Hi Stoik, although I merely designed the model and didn't build it, I have a lot of photographs of the prototype being built. If you send an email to the admin of this site, they can pass my email address to you and I'll send you the pictures of the control linkages that I have. Another modeller is building a twice sized version from the plan, when complete, I'll post images of it here too.
Pete Theobald : Avro 641 Commodore : 09/12/2025

Someone needs to build this. If not to fly, at least to light on fire and throw from the attic window. (When it's wet outside.)
Lincoln : Supermarine Racer : 08/12/2025

Nevermind. I see the stabilizer slides into the fuselage.
A label for the stabilizer would help
Richard Briggs : Boston Revere Speedster : 08/12/2025

The lower longeron at the tail shows it going all the way to the bottom of the vertical rudder. the photos on line show the horizontal stabilizer attached to a horizontal stick. Not the lowest longeron. The plan Should show the lowest longeron ending at the last vertical stick. Allowing the stabilizer to be horizontal. Without the photos online the rookie modeler (me) wouldn't have found this out until completion of the fuselage
Richard Briggs : Boston Revere Speedster : 08/12/2025

Fixed now, see update. The page at ivcmac.bmfa.uk/malmstrom-plans has two available versions of this plan, on A3 and A4 sheets. This A4 version is complete.
SteveWMD : Livesey DL5 : 08/12/2025

Nice plan but no ribs shown just the leading edge and spar position.
Simon Rogers : Livesey DL5 : 08/12/2025

A very nice little aeroplane! I am currently trying to build it. Would it be possible to get some more photos? I would like to take a closer look at the aileron/elevator and rudder linkages.
Stoik : Avro 641 Commodore : 08/12/2025

Hii Mary and Steve, New model done [main pic, 006-009]. Original scale 12 inch span.
Best regards,
Maciej : Ercoupe : 08/12/2025

If I make a 44.25” version can I call it 1/4 Scale?
Dave : Toadstar : 07/12/2025

Kent is company of drawings instruments, it seems that draw straight was a kind of ruler. Considering the all square shape...
pit : Toadstar : 07/12/2025

I'm in process of building one of your gliders to use as a parasite (strap on) glider to be released at peak of flight form one of my model rockets.
Harry P Neuman : Balsa Baka Bomb : 07/12/2025

Draw Strait is fine, but Too Rich A Mixture is quite a stretch :)
Miguel : Toadstar : 07/12/2025

It appears there is a typo error in the instructions. The wing construction refers to the setting dihedral at the No.1 rib, but if you examine all the pictures the center section is flat, no dihedral. However, if you number the ribs No.1 at the center and No. 5 at the wing tip then the instructions should read; ‘
Pin down the leading and tip trailing edges on the plan.
Cement the No.1 rib in place. Use shims to raise the center section trailing edge up off the plan and cement to the No. 3 (NUMBER THREE) ribs.
Add the rest of the ribs, trimming them at the aft end as necessary.
When everything is dry, crack the leading and trailing edges at the No. 3 (NUMBER THREE) ribs and raise each tip 1-3/8 inches for the proper dihedral.’
This way when removed from the board the center section will be flat and the outboard tips will trail below the center section trailing edge.
Also note if you print this on tabloid (US 11x17) it will come out under sized, it has to be printed in poster mode.
Thomas Solinski : Zephyr : 07/12/2025

For those of you fool enough to actually build this monstrosity, realize that the plan as downloaded is 1/4 full size, only the rib is correct as shown. That means you have to enlarge the plan by 400%. If you plan to print it in "tiles" on your printer, get 170 sheets ready, may take a while. Buy some more ink. Draw your plans on a roll of WalMart poster paper on a LARGE table, each part a new drawing. The fuselage, as measured, is 32" to the tip of the rudder, which works out to 128". Go ahead and buy yourself a bread truck and get it over with. But there are good ideas here, the foam board ribs worked out just fine on my 84" Ugly Duck, still flying after 20 years. Not Dollar Tree foam, not strong enough. I didn't like the foam spars, used 1/4" x 1/2" pine for the Duck. No struts needed, cut the ribs stacked 4 each with a scroll saw. Fuselage could easily be made from 1/4" balsa sticks, lighter and stronger. Go for it Dude, lotsa leftover 61 engines available for free. Cover with Doculam, cheap enough to be classified as no cost.
Doug Smith : Toadstar : 07/12/2025

Hello all, Here are two pics of the Jay-Pee built from the plan in the magazine way back then [pics 004, 005]. It is a simple but strong model, easily assembled. Mine came out at 36 inch span although I can't remember why. It was built without the wingtip pods and canopy. Mine flew originally with Cox .15 Sportsman, then later with the first style Fox .15, steel cylinder fins, as you see it now.
An excellent flyer as you can tell by it being intact with no repairs.
Ed Shearer : Jay-Pee : 06/12/2025

Hi Steve, Here's a picture of my Talon [main pic]. I built one when I was 14 (more than 55 years ago now). He had a Super Tigre 15 without an exhaust, simply because I didn't have enough money to buy one at the time. I recently built another Talon, hopefully, this one will have a longer life. The previous one only flew two laps, because I'd never flown a CL before.
Greetings,
Dirk Wijns : Talon : 06/12/2025

Good tip! thanks Hubert, (the Zero is oz7419). I built a Guillows Zero for Cox Medallion 049 for control line, which flew really well.
JimP : Spitfire Mk XIV : 06/12/2025

Hi Steve... since you were given all this new information, might as well have the published date, which is June of 1985. Will send you the article by e-mail, from which you can grab a couple pics.
RC Yeager : Yak-3 : 06/12/2025

HPA and Sand T were a scheduled 'change of supplier' but it was due to be back up two days ago. Nothing yet.
bill dennis : Breguet 960 Vultur : 06/12/2025

Got it. Have updated these details now. Many thanks :)
SteveWMD : Yak-3 : 06/12/2025

Designed by Jaroslav Fara, published by Modelar. Wingspan 1090 mm, which is approx. 43 inches. For 0.15 to 0.21 cu.in engines.

Hi Jim, as an exercise both in building and especially flying try the Zero first.
Hubert : Spitfire Mk XIV : 05/12/2025

Thanks for another great plan which will be going on my to build list.
Ps is the stick and tissue website down? I've been unable to get on it for over week.

Andrew Snelson : Breguet 960 Vultur : 05/12/2025

Oh I like the fake engine! I will have to do that for the MK Curare I am going to FINALLY finish off in 2026 in honor of the designs 50th anniversary. Maybe I will hang one of my unused tuned pipes on there as well.

Hello Steve & Mary, Please find attached a couple of photos of my Quick 60 [main pic, 005-007]. It is powered with a McCoy 60 series 20 just like the original. Many thanks for keeping Outerzone up and running, it is a great resource.
All the best,

Hi, Here is a clip from the instructions [pic 005] that lightened my day (aka lol..), following up on my comment enthusing about the instructions. (They are concise but definitely useful for a quick build, and I found them interesting to read; most unusual!)
(Well.. I found this clip amusing anyway)
cheers,
JimP : Spitfire Mk XIV : 04/12/2025

I wouldn't normally consider this type of plane, too fast and small for me, what with tip stall worries et al... but I was really impressed with this one; I am going to give it a go !(with a stabilizer elev thingy of course). And it is tough and simple-to-repair so "landings" are not to be feared(?)
What really sparked my interest tho are the instructions which are the best I have seen (in this category). I even learned a few things..amazing. Now where did I put that OS15?... wait a mo I expect a 10fsr would work built light?.. or a diesel....
JimP : Spitfire Mk XIV : 03/12/2025

Have changed the spelling here now from 'Gymn Dandy' to 'Gym Dandy'. Which is the way it appeared in print, and in the index.
SteveWMD : Gym Dandy : 03/12/2025

Amen!
Jan Novick : Bloch 175 : 02/12/2025

Sigh. What is it that you want to happen now? Some policing of the use of correct terminology? I'm not convinced as yet that anyone else here wants that. Everyone else here seems to be just having fun.
SteveWMD : Bloch 175 : 02/12/2025

By definition, an approved pseudo dimer plan is 11"x 17" (ledger size) with a letter sized parts sheet, so everything fits nicely in a magazine-sized format at 100% and does not need to be rescaled!
Also, several nice "approved" dimer sized twins have already been published, and examples flown in FAC competition.
Join the FAC, rather than telling them to "rejuvenate" their in-house rules. In fact this particular requirement was clarified in a recent rules revision. Lots of organizations send out exclusive content to their members. Nothing wrong with that!
DA : Bloch 175 : 02/12/2025

Excellent! Thank you
Rodrigo Burgo : Bloch 175 : 02/12/2025

"This plan was drawn to see if a viable twin Dimer could be built to fly in the Dimer style construction."
The design is an exercise in building in that type of construction.
pmw : Bloch 175 : 01/12/2025

I'd hazard to say that the Outerzone has as large a circulation as all the publications mentioned. If not larger. As for credibility, I'd also state Tom Akery's scale designs are generally recognised to be as accurate to prototype as any.
His plans may contain errors? Perhaps (where?), but so can plans from the Great Ones in printed sources. No one is exempt.
Also, these plans in online format are also much more practical to print into building size than magazine plans that you have to rescale. Perhaps that rules paragraph is in need of rejuvenation.
Miguel : Bloch 175 : 01/12/2025

From the current FAC rulebook: "New pseudo Dime plans must appear in a recognized print publication such as a local club newsletter, NFFS Journal,
FAC Newsletter, etc. to be approved as an Official Dimer for FAC events." Emphasis on "print publication."
Da : Bloch 175 : 01/12/2025

I bought a "Bird of Time" on a fleahmarket , quite cheap, because the elevatorpushrod was disabled by a drop of epoxy....Unluckly I had no plan so I had to get the CG by experiment, later a comrade gave me the right place....Flys fine now, but I didn`t ad spoilers yet...
Reinhard Lehmann : Bird of Time : 30/11/2025

Ok, sorry for the confusion. Have replaced the plan in this slot here now. Previous was a duplicate, see Gymn Dandy (oz5120)
SteveWMD : Zephyr : 30/11/2025

Doh. Turns out this plan (Gym Dandy) was a duplicate entry, see oz5120. My mistake. Ok, will replace this plan with another in a mo. Bear with me.
SteveWMD : Zephyr : 30/11/2025

Hi Bill, yes it is my recommendation, I put at least 1/16" under the TE of the tail, on the plan it is drawn at positive incidence
Mike Hollamby : Pixie : 29/11/2025

Hi Mary, hi Steve, attached are two pictures of my Helio Courier profile model [main pic, 006]. The model flies very nicely. I've re-done the nose to add a bit of downthrust.
Here is also a short video: https://www.youtube.com/watch?v=z9zuDtTNeio
Thanks for this wonderful site and cheers
Alexander Weber : Helio Courier : 29/11/2025

In the new SAM35 Speaks, the recommendation is to add some incidence to the tail because it is zero-zero. Any thoughts on this, anyone?
bill dennis : Pixie : 29/11/2025

Nitra is a cute town in Slovakia with a lot of history. Notice the shield on the fuselage.
Tom : Nitra 3 : 28/11/2025

I love quirky models, and this one is right up there at the top. Thank you for sharing this masterpiece. I'd love to see this on my slope.
John Green : Nitra 3 : 28/11/2025

Such exceptional artistry, the most romantic and whimsical of scale aero models.
Madhukar : Nitra 3 : 28/11/2025

James Adams built two CGMs. The first film covered one was RC which he later converted to FF. The Red one Big Red had a Brown and was flown exclusively freeflight.
He said he had to shim them at the TE because they had too much incidence. This goes against Otto Bernhardt’s experience but he used an all-flying stabiliser. Take it for what it’s worth.
The 1/2A Texaco was campaigned by Colin Borthwick who also had a full-size CGM. He named the Arrogance & Impudence.

SteveWMD : Sportmaster : 27/11/2025

FAC has an Embryo event. AMA has Bostonian. So, the notation on the plan, and the comment in the description (FAC reference) are confusing.

Sam Howe : Contender Gold : 27/11/2025

I'm Dave Surace, I designed this model PCA-2. I used three rotors as they worked very well. Four rotors = more drag and rotors that need to be 3/4 the cord of origanal 3" rotors. That being said, the lift is significantly less and your need a stronger motor to pull all that drag and weight. The frame will not support all that weight. Only one guy did it succesfully. He put a radial engine on it!!!! I dont think it lasted long.....
Dave Surace : Pitcairn PCA-2 Autogyro : 27/11/2025

Perfect thank you all
Dave : Vought F4U-1D Corsair : 27/11/2025

The same design I mean a single prototype for test in the US, according to the wiki link above.
SteveWMD : Dornier Falke : 26/11/2025

Dave, the center and anhedral portions of the wing require 14 total ribs... four W1C ribs, four W1LG ribs and six W1 ribs, so they're all there. I think your confusion stems from interpreting that the outermost portions of the center section consist of two W1 ribs glued together, but in fact its a W1C rib glued against a W1 rib (then followed by the two W1LG ribs, spaced apart and two W1 ribs glued together).
RC Yeager : Vought F4U-1D Corsair : 26/11/2025

Hi Bill,
Nice to hear from you - that was the Rollason Condor.
Dick van Mourik : PZL P.24 : 26/11/2025

Jim Adams--SAM President in the early 1990s flew one of these in FF Texaco event. Hal Wightman flew another in the aughts at Perris California using a small four stroke glow engine. There was a half size (48 inch wingspan) version which did well in FF 1/2 A Texaco events at Taft in the 80s and 90s.
Mike Myers : Contest Gas Model : 26/11/2025

Fixed the missing article page now, thanks to JeffGreen.
SteveWMD : Vought F4U-1D Corsair : 26/11/2025

Thanks Mark. I hadn't heard of Bessie Coleman before - she must have been a remarkable woman. I found this great photo on Wikipedia [pic 012] here: https://en.wikipedia.org/wiki/Bessie_Coleman
Mary : Curtiss JN-4D Jenny : 26/11/2025

The Wright WP-1 is very similar or the same design, depending on which internet source you trust.
LR : Dornier Falke : 26/11/2025

Would anybody have the missing instuctions from the centre of the article regarding starting the fuz build ,also theres not enough w1 ribs on the parts sheet , it needs 8 and theres 6
dave : Vought F4U-1D Corsair : 25/11/2025

I downloaded it this when in was published.
What are the updates on the Winstanley version? lt looks the same.
Mike Windsor : 1989 Bomber Beater : 25/11/2025

Yup, not TeeDee power, but a good little throttled engine. Your only other option is a G-Mark or PAW .03, or an old light 1/2a motor (like a Cub or a Fox) adapted to RC. Exhaust restriction is usually the best choice.
Dave : Littlest Stick : 24/11/2025

A question for DFritzke, wouldn't a Pee Wee cylinder revert the motor back towards Pee Wee Power, the porting was different just like the .049/.051. I bought a LS from a hobby shop along with an Ace single channel radio and put a Pee Wee .020 I had in it, it was pretty sporty with that. Unfortunately, the radio was on 27MHz and CB radio was still quite popular, so I ended up chasing it more than a few times since I flew it near a freeway.
Douglas Babb : Littlest Stick : 23/11/2025

RC Yeager,
Thanks for your encouragement. I'm closing off the requested plans for now. Ha Ha! It was fun. The most challenging was this model. I appreciate your words!!
Tom
Tom Akery : Junkers G.38 : 23/11/2025

Hi Tom... If I may, I would like for you to design three planes for me. The first one is... JUST KIDDING TOM... don't fret, I'll do my own work. You are an IMMENSELY better man than I am Tom.
RC Yeager : Junkers G.38 : 23/11/2025

I made this model from the CAP kit some 25 or 30 years ago. Building was great fun on dinner table (we ate at a different one). Not difficult and fun to put together. Was the building instructions, I don't remember. Installed simple servo-operated retracts, covered with polyester fabric, sprayed with filler, sanded, painted with Humbrol scale colors and final fuel proof mat.
The only problem with this model was the set up for a pusher .60 engine with two (pressured) fuel tanks. Ingenious, but hopelessly impossible to service except by cutting open the fuselage. I made it, but after many tests runs the first take off was nice. 20 meters up, engine cut.
Crash landing? No! The model came down like a pancake; slow, flat and stable! In the grass of the very end of the strip. Only the light ply supporters for the retracts broken.
What happened and why? I do not know, and so parked it under the ceiling of my study - till now. Not happy about the complex fuel system, the mess of fuel on models and the using two-cycle engines on jets, like this amazing one.
This plan can easily be converted to El by a person with some knowledge of modeling: for a single or several pushers. I may also inform that this very plan - by Rob Fraser - is now also available at SARIK HOBBIES with the plastics.
I can send you photos of the model.
Odd Terje Branteberg : Avro Vulcan : 23/11/2025

The banana shaped wing panels are unlikely to become a trend. Reminds me of the COX control line plastic planes that always seemed to have warped plastic wings. Not a look most aviators would admire.
Patrick : Sky Flieger : 23/11/2025

Thanks for all the info, Tom. Helps a lot. It's a great looking plane.
John Washam : Breda 39 : 23/11/2025

elliptical dihedral is used to have a better airflow at the wingtips. In order to have this result spars are to be omitted and the secret is to cover and strenght the top of wing firstly.
Pit : Sky Flieger : 23/11/2025

Hello, if I may ask I have one more request. I’ve been looking everywhere for 3 views that show a cross section of the fuselage shape at separate points of this aircraft, it is the Stout ST-1. I believe it would make a very good and “floaty” model with the wide wing chord, but there is just very little information on it that I believe you would be the right person to ask.
Gage Van Vranken : Breda 39 : 23/11/2025

Hmmm. Seems like the whole point of this design is to have an open, high lift and very undercambered wing. Without spars.
SteveWMD : Sky Flieger : 22/11/2025

The electric conversion Curtiss JN4D Jenny partial kit by Joy Products came in at 3.8 lbs [pics 009-011].

Hello Mary, I recently unearthed a Southern R/C "Compensator" kit that I have had for 50 years. When I opened it I discovered there were plans for the wing but not the fuselage. For whatever reason the fuse plans were for a "Bobcat". Another kit that was made by Southern R/C. Thanks to your website archive I was able to download a copy of the proper fuselage plans.
Here are a couple of photos of where I am at in the build [pics 006, 007]. I will send more photos when I get it finished.
Thank you again for all the work you put into this wonderful archive.

bill dennis : PZL P.24 : 22/11/2025

Tom, Like you I like the odd ball aircraft. I have been wanting to draft up a plan for myself of the Ursinus/Gotha Seaplane WD10, but have not got around to it yet. While thinking of the long list of models I want to build from your stable of plans I thought, hemm, I wonder if Tom would think that the Ursinus/Gotha Seaplane WD10 is quirky enough for him to draw a plan set up. What do you think is the Ursinus/Gotha Seaplane WD10 enough of an odd ball for your tastes? Would you want to do your magic and draft one up? I would love to add it to my loooong list of Akery plans to build. Thanks.

Have shuffled the photos around, so now the main pic here is Bryan's model, previously shown on the other RQ plan page. This is a much better pic to illustrate this particular plan. The previous main model photo is now at pic 003, shows Col Taplin himself with a much-modified electric model.
SteveWMD : Radio Queen : 21/11/2025

Oops,
John,
I assumed I used the Sliced Rib construction on this plan. I did not! Rather I used the "Cracked Rib" wing construction. This method makes a quick and light wing. Here's a tutorial on this method on my site, stickandtissue.com : https://www.stickandtissue.com/forum/cgi-bin/yabb2/YaBB.pl?num=1750020740
Regards, Tom Akery/Sky9pilot
Tom Akery : Breda 39 : 21/11/2025

John,
I left out the great tutorial by Mike Stuart on his site: https://www.ffscale.co.uk/rees.htm
It's a great explanation how the Rees' Sliced rib wing is constructed.
Thanks again Tom Akery
Tom Akery : Breda 39 : 21/11/2025

John,
My apologies for not making this clearer. I tend wing it with what I have in my head during construction. It has been pointed out to me just recently. To help you out John, If you have a good ruler, just make a measurement of the wing root airfoil on the plan's side view. Then take off 1/16" from the top and bottom of the airfoil which leaves the size of the root dimension of the spar's height in 1/16" sheet and taper to the 3/32" tip height. I hope this helps in you understanding. Often I will place the rear spar after the upper sliced rib is in place and measure the gap between top and bottom of the ribs and cut the spar and slide it into position. I'll try to do better in this area and thanks for looking at my plan.
Regards,
Tom Akery/Sky9pilot
Tom Akery : Breda 39 : 21/11/2025

Hi Steve. Nice looking plane. Tom has a good eye for choosing them. Would like more info on the wing, like the spars and ribs. It would make it easier to build, especially for a novice. Thanks, John

In the parts list of the Edwards, the Perry #302 or #205 carburettor is recommended, see "General Notes". I made a down-scaled version, 30 cc instead of 60 cc, and I use a 50-year old carburettor of a Super Tigre 35 ( 5 cc).

Hi Admin please see attached photos [main pic, 005]. Fop flight Jr Flite Streak plan oz14458. Flys on 50 ft lines 40 year old fox 15 for power. The fuel tank is far from perfect (looks awful but it works) flight is stable fast and manageable. Fun little mojo build put together in 5 days start to finish.

Have finally found the propellor for power models that I used inthe 1980's.
It is on page 52 of the AEROMODELLER ANNUAL - 1952.
I tended towards the speed propeller. Carve the prop in form the squared off blank then shape the tips to desired shape. Use a close grain hard wood, and if laminating use a strong glue.

The negative dihedral of the rotor it's only with the rotor stopped. When the rotor starts to rotate, the blades take horizontal position, thanks to the centrifugal force. And, in fly, the blades take positival dihedral because the weight of airframe.

Steve, Mary, Here are some pictures of my rendition of the Mystic Model Co. dime scale Miles Sparrowhawk (oz16378). Mine was built in 2020 from the plan as published in the March/April 1991 Flying Aces Club newsletter (issue 180). The designer is Daniel Marcus.
Color and markings are from 1949 pictures of G-ADNL. The model is light and flies well, although the high thrust line limits how much rubber you can stuff into the fuselage for outdoor flying. Best time from it so far is around 100 seconds, with a bit of help from thermals.
There's a short build thread for the model on the Stick and Tissue forum here: https://www.stickandtissue.com/forum/cgi-bin/yabb2/YaBB.pl?num=1595736763/0
Thanks again for all you do to keep these plans available. Cheers,
Mike Kelly : Miles M-5 Sparrowhawk : 12/11/2025

Dear Mary & Steve, Just to show my version of Ray Malmström's Saab J-29 [pic 003]. Jetex Atom-35 being very rare, I went with an enlargement to 13" wingspan and rubber power as a no-cal. This model has a very minimal balsa frame with 2mm wall foam covering sprayed with Tamiya acrylic paint (shake can). Flies very well!

CoG should be very little in front of rotor, but the negative dihedral of the rotor will lead to instability it should have positive dihedral as we know from the wings otherwise it will fall put of the sky. Another problem will be the angle of attack of the rotor as the air should pass from the underside to the top it is helpful when the axis points some degree to the back.
Matzito : Pitcairn PCA-2 Autogiro : 12/11/2025

Jan... from A.I. (yeah, I know, but based on my own knowledge, I believe this is more or less correct:
"No, the center of gravity (CG) of an autogyro should ideally be slightly forward of the center of lift, not directly under the center of the rotor. This forward CG position is crucial for stability, as it creates a nose-down tendency that is balanced by the rotor's lift, allowing the pilot to maintain control. If the rotor's center of lift and the CG are aligned, the autogyro could become unstable.''
RC Yeager : Pitcairn PCA-2 Autogiro : 12/11/2025

If memory serves correctly, the CG of an auto-gyro should be directly under the center of the rotor.
Jan Novick : Pitcairn PCA-2 Autogiro : 11/11/2025

KW has you covered. Almost all kit plans show how to assemble and are not intended for scratch building so some interpretation is necessary to do so.
One more point, your maximum width is twice the distance from the center line (C/L) to the flap. This is shown on the wing plan, and you will be building to slightly less.

pit : KA-10 : 11/11/2025

Matej
You are right - there are no fuselage formers shown.
However - determine the width of your engine bolt pattern - you now know the center line of the hardwood engine mounts.
Add the width of one engine mount to the width of your engine bolt pattern - you now have the distance between the two outside faces of the engine mounts - assuming the engine mount bolt holes will be on the hardwood engine mount center line.
Use this figure to determine the inside width of the fuselage sides. Add the thickness of the ply doublers and the two balsa sides to determine your actual fuselage width.
You can also incorporate side thrust with wider engine mounts that are cut to suit and downthrust using a thick firewall and a second fuselage former.
Or - use a commercially available engine mount and a thick reinforced firewall.
Size your total fuselage width to suit whichever mounting method you use.
Also - look at other plan sets - there is literally a whole world of ideas there.

The article explains, ribs are produced by the sandwich method. So all you need is the root and tip rib patterns. You know, I wonder how many times have I typed out these exact words.

Hello, I have build the Kwik Fly from Graupner [pics 014-018] between January and May of this year. It is equipped with Electron retracts, a Saito FA 82b fourstroke engine controlled with an on board glow system for easy engine start by hand. This system can be controlled by hand via a push button located on the left side of the aircraft fuselage or by a switch on the transmitter. In addition there are navigation and strobe lights as well as a beacon on the lower side of the fuselage. The aircraft was covered with Proficover 2 from Tony Clark.
Best regards,
Matthias Todt : Kwik Fly Mk3 : 10/11/2025

Hi Steve and Mary -- Here's another of my projects "in the bones". This pic is the MiniTelemaster [pic 003] about in 2017. After this little beauty, the sadly departed Hobby Lobby produced an updated version of the plane with die-cut fuselage bits and simplified wing structure, but this one is the version in the Outerzone plans and this is the one that's much prettier and more satisfying to build :)
Thanks for the Outerzone, and best wishes,

Hi Steve and Mary -- This is the Esquire my dad built from a Midwest kit in the early 1960s [pic 010]. The finish is nylon and dope and (although I don't think it shows) control was single channel, rudder only, pull-pull.

This is my version of the Comet Super Star P-51 [pics 009-012]. I modified it to look like the pylon racer Voodoo with custom art from my wife’s (Sheena Lange) graphic designs. I call her Ghost Cat.
When I built her I also vacuum formed custom P-51D and Voodoo canopies that fit directly to the original fuselage.
Thomas Lange : P-51D Mustang : 10/11/2025

It says 51 in the article and 48 on the plan, so I guess you can take your pick? Just measuring the plan now, it will print at slightly over 51 (flat, of course), so let's go with that.
SteveWMD : Minnwatt : 10/11/2025

Looking at the article, in the specifications it states wingspan as 51 inches, I guess that is flat on the bench with no dihedral?
Douglas Babb : Minnwatt : 10/11/2025

It's a great flying model but I strongly advise you a) sheet the LE, otherwise it will pull in b) use separate wing panels c) don't be tempted to use a separate rudder; it's very powerful.

Thanks Doug. I'm keen to build this from the actual KK kit plan, mainly from nostalgia, but I'll take a look at the Jetco plan, thanks.
SteveWMD : Piper Super Cruiser 40 : 09/11/2025

Steve, consider the Jetco version of this plan, same size, same designer, appears identical. 15067. No instruction book, but plans show extensive construction notes on the plan, a cheaper alternative used by many kit makers back in the day It's not a real good scan but text is readable.
doug smith : Piper Super Cruiser 40 : 09/11/2025

A wonderful airplane! In the early 70s, I built two "Champs". I recently completed my third.
Thank you Mr Debolt for all you have done for modeling.
Wes : Live Wire Champion Mk III : 09/11/2025

Does anyone have a copy of the instructions for this kit? I'd really like to build this myself. Would be good to have a scan of the original instruction pages.
SteveWMD : Piper Super Cruiser 40 : 09/11/2025

Thank you for the amazing plan. The super savage is one of my favorite aircraft in general. It really gives that flashy yet vintage appearance. After I finish my dumas sparrowhawk, this will be next.
Gage Van Vranken : NAA XA2J Super Savage : 09/11/2025

This plan is good because it has the outline for the cabin version. That version is easier to balance because the wing is further back. You could scale this cabin outline up 108% and apply it to the1989 Bomber Beater (oz16371)
Michael Togni : Playboy Senior 93 : 08/11/2025

A remarkable rendition that shows what can be done. The simplest way to improve an SE5a model like this is to take a sanding block to the wing tip and increase the radius at the LE.
bill dennis : SE5a : 08/11/2025

Re: Roger Smith's 2021 comment above - this is not correct. Memory playing tricks no doubt!
I had an email exchange with Dave back in 2022 and this is what he said:
'Sorry if this is a disappointment -- my memory says the scheme was Grey over White, with Black trim.'
Richard Scott : Fleetwing : 07/11/2025

Tim, to get the best out of these old plans you are going to have to put in a little work for yourself. Start by reading the KnowledgeBase pages here on Oz at https://outerzone.co.uk/knowledgebase/index.asp that detail how to work with PDF files, how to check page size, how to check scaling. Once you've learned that much, you don't need a scale bar any more. And that means you can use any one of these (thousands of) plans.
SteveWMD : Tiny Twister : 07/11/2025

That [main pic] is the late David Baker--one of the founders of SAM 35 in England--and later the founder of SAM 1066. David was an enthusiastic promoter of old time models both in his home in England and on his many visits to the United States.
Mike Myers : Falcon : 07/11/2025

A good addition to this plan would be a scale indicator so it would be easy to accurately know the size of each piece.
Tim : Tiny Twister : 06/11/2025

I don't see the wing rib drawings for the airframe on this Balsa Nova plan or any other similar plans. Anyone have a PDF of the wing rib drawings? The dual taper ribs are clearly called out in the original kit.
Dave Thomas : Balsa Nova 1.20 : 06/11/2025

Update 06/11/25 yes European format! Doing a little research. The drawing is odd that it says 'DEFENDER' with registration NC9A on the tail. But, NC9A was Goodyear's original 2 passenger blimp the PILGRIM. Defender was NC12A But the gondola on the drawing is too big to be the Defender. So, that leaves the Puritan NC 7A, the Volunteer NC8A, or The Vigilant NC 11A as the closest candidates for what this model was supposed to be.
Thomas Solinski : US Baby Blimp : 06/11/2025

M Stikeman : Dixie : 06/11/2025

In about 1982, a friend / schoomate and me developed a craze for rubber powered models. Among them was another biplane called Twinny by Günther Flugspiel. Like most model aircraft by this manufacturer it had styrofoam wings and a vacuum formed fuselage which definitely limited lifespan. It flew quite well and it looked just great. Seems like in these years people were a lot more relaxed about the names they or others gave their products...
Martin K. : Twinny : 06/11/2025

Hi Mary, I recently built the Stiletto 660 from your plan download and thought you might like a few photos [main pic, 005-008].
I managed to get a Stalker 46 from the Ukraine two weeks after the Russian invasion had begun. The engine arrived safely but I didn’t have a project in mind at the time. I have always liked the Stiletto appearance but as I got into the build I was quite impressed how easy it went together. The top block arrangement is both easy and economical compared with hollowing out thick block. The model flies well but the motor was more economical than I anticipated giving me an 11 minute first flight. Fortunately the tank is removable and I have since experimented with 3 different tank sizes.
John Lewis : Stiletto 660 : 04/11/2025

During the COVID lockdown I scratch built one of these from plans using an OS 15FP as recommended. What a little cracker! Three years and many flights later I'm still hand launching her on still mornings, thoroughly enjoying slow, elegant aerobatics using amounts of glow fuel equivalent to that spilled refuelling a large model. Great fun!

Steve, I was quite surprised to see the plan for the Thermic Traveler. It was a kit I produced in the early 1980's. It was a long lost hand drawn ink plan. Thanks to the donor for scanning the drawing.
I found some pictures that are attached [pics 007-011].
The Traveler was designed to be taken on trips in a plastic gun case. I recollect that it flew great with electric power and even better as a pure glider. This was a time when folding props were new. I had a Geist prop on an Astro 05 on the model shown in the photo [007, 008]. The prop hub broke off during the climb and vibrated the plane to pieces.

Mike : Albatross 47 : 04/11/2025

Built this one a couple of years ago - overall a nice sport model and I always liked the look. If I were to do another I'd think about adding an inch or so to the fuze length as she's a little bit twitchy in pitch.
Jerry Cashman : Fantasy 2 : 04/11/2025

HolaHi, excellent plan!! A great contribution to the wonderful RC flying community! I'm about to build my Extra300 with this plan. Just to confirm, is the material for F1 to F5 plywood? Or was it made of balsa wood? I can't tell from the photos. From F6 onwards, I see it's 2mm balsa.

You don't need more Littlest Stick photos, but here are a few anyway [pics 009-012]. I ran across some remnants of my very first LS stashed in the basement rafters of my father's house. Back in 1977 this had a Cox TD .010 and an Ace rudder waggler radio. I cut some bulkheads, built a wing, added 2x9 gram servos and a Park 250 motor and Volia! Another one to bash around the local schoolyard.
