Just a note. The Seamaster 120 (ID 10817) presented here is a enlarged version of the Seamaster 2 (ID 5899) published in the May, 1984 issue of RCM. As the plan details are similar, the article and building instructions for the smaller (48-inch) Seamaster 2 may be useful to anyone building this larger version. Best complements,

I built a model of the Leprechaun from APS plan about 1990. The problem I had was that every time she landed the rear end of the fuselage broke off, immediately in front of the tailplane assembly. As many models of the Leprechaun fly successfully, can anyone tell me what I did wrong? Wouldn't mind building another Leprechaun using Depron and an electric power pod.

Many thanks for publishing the Soloist plan. I built the Soloist about 1989, and learned to fly RC, without any problems, using the model. This was after about 3 attempts on other models I had built. I have now used Posterazer to print the plan out on A4 sheets. I have done the wings and fuselage separately using landscape mode. Saves paper and does not cause distortion problems trying to make one full size plan. If anyone wants copies of the Posterazor sheets just email me on

We too were very much addicted to this design. Some of friends learned flying with this Junior 60. I build this from scratch using locally available wood. No balsa.

This is more a comment than a correction on the Seamaster 120. However, if heeded, will lead to several corrections. When this plane first came on the market, I was an ACE dealer and like another dealer, in the USA, we could not wait to test it. So we each built one, being the first two on the water. Could have been much improved prior to release. Too much plywood - almost every part - meant an extremely heavy plane. My recommendation is to eliminate it in most places, including the wing ribs, minor bulkheads and especially the tail. It makes the tail end too heavy and very weak by placing the heavy horizontal stab on top of the flimsy, heavy vertical fin. Those heavy, poorly fitting brace wires don't help much. In fact, they shake and rattle so much when the engine is running that you may even generate RF interference due to the metal to metal contact. The clevises do not fit their straps properly. And the vertical fin must be strengthened to hold the stab without shaking. Also, the choice of wood for the engine pylon was weak and flexible. My first engine was a Super Tigre 2500 which proved totally inadequate for power. It was replaced by a Quadra 42. Both the other builder and myself then experienced extreme problems with flying, especially in turns. The plane would not fly properly no matter what we did. And for me, that was the case with both the Super Tigre and Quadra engines. There were continuous calls to ACE and between us to sort it out. Ultimately, the only solution to get a somewhat proper flight was to add a large dorsal fin, from about half way up the existing vertical fin to almost the trailing edge of the wing. The big issues were overall weight and improper attitude in and flight in turns. I also believe that the claim of flying this plane, as designed, on a 1.08 2 stroke or 1.20 four stroke engine is quite a stretch. It needs more power and thrust, as provided by the larger displacement and prop of the Quadra. There is no substitute for cubes.
MatthewStikeman : Seamaster 120 : 21/01/2019

Aha, got it, thanks. The "B Ashby" must refer to the draughtsman rather than the designer.
SteveWMD : Sunnanvind : 21/01/2019

Sunnanvind was designed by Sigurd Isacson from Sweden and the model was revolutionary for its time and set a new standard for singing speed and wing profiles.

Please accept these photos of the Gee Bee Dreamer biplane I built about 15 years ago or so from a GEE BEE line kit [more pics 003-006]. It, by far, was (the wings and the back half of the fuselage still is) my favorite airplane. It was powered by an Enya .40 TV from the early '80s. Covering was silk and dope. Originally it had an inverted PAW .40 in it but that was swapped to the Enya. After a major wreck, the nose was repaired to accept the Enya in a side mounted fashion and a cowl was built of balsa. You may notice the shock absorbing landing gear utilizing car shocks. Its demise occurred shortly after I replaced the Enya .40 with a first generation Fox .45 schnuerle engine with a reverse running crank. Gobs more power and reverse torque and "P" factor. I knew it would be short lived with that combo. I'll repair it some day! (It actually landed slower with the skis than the wheels which contributed to a few "dropped in" landings each spring!) The photos were taken by Dan Clune.

Usually when you see an end view of an item with two parallel lines on the inside of the item, it denotes 3-ply plywood. The plan view of model shows that almost every bulkhead is plywood.
rchopper56 : Cessna Skymaster : 21/01/2019

OleBill has done a great job improving the Comet Vengeance fuselage formers, but the rear formers need a bit of a tweak. The attached photo of a Vengeance without the tailcone [more pics 007] shows the rear fuselage cross section to be similar to the front fuselage and not 'sort of elliptical'. The side view of the fuselage on the Comet plan is also not too good and would look better if it was corrected. I have included a more accurate one I found on the web. Unfortunately when you go down this road you soon reach the point where the next step is to bin the kit and scratch build the model!
ChrisPinn : Vultee Vengeance : 21/01/2019

First of all, thank you for the free download which I successfully downloaded and printed full scale on tiled paper. I would like to know how to identify which parts need to be plywood, especially for fuselage construction. Like F5, F7, F11, etc. Your kind advice would be very much appreciated.
SC : Cessna Skymaster : 21/01/2019

I noticed you did not have a picture of the John Bell H-1 racer. I have built two from the John Bell plans [model photo & more pics 003-006]. One at the original 20" wingspan as a rubber powered model, and one enlarged 150% to 30" wingspan as a 4 channel electric radio control model. These are very good plans - I had to do my own patterns for the canopy glass and for the wing fillets, everything else is shown. I deviated from the plans on the engine cowling. The 20" shows four blocks to make cowl. I used eight on the 20" and sixteen on the 30". The 30" has extra stringers in the wing to make it more rigid. Both models use the enlarged horizontal tail shown on the plans. The formers are also still 1/16" on the 30", though the stringers are 1/16" on the 20" and 3/32 on the 30". Both models are great flyers. The wing fillets are the only difficult part to get correct, they are a double compound curve. They were easier to do from 1/32 balsa than from paper or card, and easier on the larger model due to the size. I would be happy to answer other questions people might have about building this model.

Hello Steve and Mary, looking at the Zaic Cabin plan ID 10822, the stabiliser dimensions are not included (unless I'm mistaken).

Addition: If I remember correctly, Graupner continued to produce and sell this specific version as "Pilot", just like they continued the 1956 version as "Sonny", which also is on Outerzone.
Peregrine : Der Kleine Uhu : 21/01/2019

Richard's Model is a later mark of this model which has gone thru many variations from the 1950-ies onwards. The plan is for the one of the early 1970-ies whilst Richard's model appeared around 1979/80. Thus, the plan is without a prefabricated forward fuselage and can easily be built from balsa and plywood, given some skills with a jig saw. I built it myself as a kid, more than once, and they flew really well.
Peregrine : Der Kleine Uhu : 21/01/2019

Plans must be expanded to 125% to match dimensions of hardware. ParkFlyerPlastics has a 3.75" vac-molded cowl that fits perfectly once trimmed to the length shown in plans.
ScreamingCheese : Nieuport 17 : 19/01/2019

I think it was an editor's mistake. The design is 44 in wingspan, not 54. Then the rib spacing and 300 sq in all work out. However, SAM has approved it as a 54 in model and lists the wing area at 340 sq in. From a flying point of view, this is better, although it leaves the stab somewhat undersized.
Simon Blake : T-Beam : 19/01/2019

This design was featured in RCM&E in August 2018, (without a pull-out plan). I felt very much like the 'Mr beginner' referred to, so I built it as an electric conversion. Power less than 60W in 2s lipo with 8x4 prop. It is indeed easy to build and very easy to fly. I particularly liked the wing structure for easy building.
Dad_flyer : Mayfly : 18/01/2019

Um, yes indeed. Jolly good. But it saves time for everybody if the plans we are hosting here are scaled to full size. That's a useful starting point (the most useful) for everyone.

KhalidKhan : Baby : 16/01/2019

This is an interesting model of the prototype, hence the cutaway wing roots, lower rear deck and open cockpit [more pics 003]. Interesting construction with sixteenth sheet to top only of trailing edges, built in quarter inch washout to both wings and extra incidence to the port wing. The wing joiner is specified as an aluminium welding rod. I changed the bottom of the fuselage from half inch sheet to built up sixteenth sheet to save weight. Possibly this model inspired Phil Smith's design for Veron but I'm afraid that one is only semi-scale as it misses out on the fuselage being raked up sharply to the tail plane. It also incorporates a lot of heavy block which needs hollowing out to keep the weight down. Now to find a suitable engine. The plan specified a D.C. Dart but for a 24 inch span that might be a bit hot.

Thought you might like my take on the Owen Kampen Pacer (oz7186), built for a brushless motor, rather than the original Cox TD 049 (even though I have a couple available!). Flies lovely on a 1000 mAH 3 cell LiPo pulling around 75 watts on a 7" x 5" prop, for around 7 minutes, with the battery only slightly warm at the end of a very spirited flight. [more pics 006, 007]
Roger_Harpenden_UK : Pacer : 16/01/2019

It's difficult to see the model in Rafaello's photograph and he hasn't given any clues as to wingspan, planform or a date for the model, but the profile looks suspiciously like the Baloney, a slope soarer featured as a plan in the January 1976 RCM&E magazine. The Baloney had a parallel chord, swept back, semi-symetrical wing of 48" span, located midway on a diamond sectioned crutch based fuselage. I had a photocopy of the plan and article and drew up a powered version to suit a .15 glow. It flew fast but, due to the rather large removeable top section over the midwing (for access to the radio gear), was a bit weak and therefore was not one of my longest surviving models! I still have the photocopy, with the dubious enhancement of a major blob of dried 'O' negative, added when it was on the back of my car during a road accident 39 years ago! We both bear the scars!! Hope this helps Raffaello and many thanks to you both for the terrific Outerzone site.

Last year, I built a R/C electric adaptation of an old free flight design, called the Double Jabberwock, by Don Srull. Here are some pictures of another Don Srull adaptation called the Electric Yogi [more pics 005-012]. I installed LED lights on the inside of the Double Jabberwock, and have done the same here. Hand launching, and hand catching, is a breeze. Easy build. If you ever try night flying, I think you will agree. It's addictive.
RobertS : Electric Yogi : 14/01/2019

I'm in the middle of a build of a Phantom Mite from the plans (in the kit my brother built in the early 1970s - with additional material from OuterZone!). One item I have - very bashed up - from the original model is a 1-1/4 inch (1.25 inch / 32mm) spinner. Try as I might, I have failed to find a replacement spinner, or indeed any spinner suitable for a 0.5cc Mills look-alike diesel with a M3.5 (3.5mm diameter) prop shaft. Likewise, finding 6x4 or 7x4 props for the same engine is proving. Does anyone know of a source today? Or knows a manufacturer looking for an opportunity at the small end? 8-)

Hello, In a recent document on RCLibrary [Title=AeroModeller_1943_01.pdf. Filesize=16908KB], link :] on pages 636-640 there's a lot of information about how to construct the model, and even a cutaway drawing giving a lot of good detail on construction as well as functions e.g. the working retractable gear. I'd like to suggest using the images as well as pages extracted as an additional PDF as well as illustrations for the plan. When I've finished mine (I've just started!) I'll send along some photos - I'm doing one as an SAAF Harvard, of the sort that used to produce a blatting roars over flying over my house when I was a child in Cape Town.

Please find attached photos of my recently completed & flown Phil Kraft Bi Fli built from your OZ plan 823 [more pics 003-005]. When I first saw the Bi Fli in an old magazine found at our local hobby shop I was hooked on the design. Must have read over the article a dozen times. Quite some time later I found the plan on your site, downloaded, printed it off & started construction right away. I made a few changes to the construction of the nose area to suit modern motor mounts & fuel tanks. I also intended to use servos instead of three escapements! The engine used is an OS 15FP with 8-5 prop - which worked out well - not over powered but enough to allow takeoff's from our grass field. This model has a terrific flat stable glide. The fuselage is covered with silk span & dope, wings & tail with Solartex. After the colored dope was applied the entire model was then sprayed with automotive two part clear in order to fuel proof. This summer I will fly it with my 2.4Ghz converted Kraft Reeds transmitter for nostalgia sake (and a step up in technology from rubber driven escapements).

Lovely model flew beautifully and a pleasure to build. It was my first electric plane. I taught a few people to fly on the Flittermouse back in the late 80's no buddy leads needed as It has very forgiving flight characteristics, I hope that this model goes down in the history books as a classic and a pioneer of accessible electric flight as it really made the best of the available power back then. A tribute to the designer for sure.

Bentsch : Junkers Ju 87B Stuka : 05/01/2019

I built one of these based on plan from 1/2A projects book of Ken Willard designs. It is a hoot to fly, and never fails at pleasing a crowd. A couple of notes: The center part of the wing is mostly dead weight... consider lengthening motor stick and only keeping the outer 2/3 or 3/4 of wing. This will also shift moment of blade outward, which will reduce coning. My balsa wing is bit prone to spitting. Consider covering it with light tissue with tissue grain running chordwise. This may end up lighter than trying to fill the balsa grain for a smooth finish. As shown, the engine thrust line is not tangent to rotation, as would be optimal. This also causes fuel in integral tank to move forward (toward crankcase) once up to speed, but rearward due to acceleration as rotor spins up. This makes it difficult to get the thing to run on partial tanks, as needed to prevent losing it. A decent solution is to angle the engine mount so that the crankshaft is tangent to rotation. Note that due to thrust of engine, and drag of wing, the center of rotation under power is a bit forward of wing LE, not where pivot hole is shown. The pivot hole is near the CoR when autorotating. G-loading causes considerable leaning as the rotor spins up. I had to set the needle sloppy rich (barely able to stay running) in order to have enough power to fly when spinning. Uniflow venting would help some, but venturi suction still has to lift fuel the length of pickup tube under G loading. A pen-bladder tank setup and FF fuel cutoff timer would be very advisable. A tall launching pole is needed if there is more than a faint breeze. The wind causes the rotor to tilt downwind when on the pole, so it 'slides' downward once free. The dynamics allow it to self level, once it is moving with the wind, but some altitude is needed for this to happen. De-thermalizer isn't really needed. Under autorotation, it performs about like a D-T'd fixed wing.

Thanks for adding your comment Bob. It's always really interesting to hear from the actual designer of a plan.
SteveWMD : Miss Martha : 04/01/2019

Good point. They do seem to have bent the nose down a bit, looking at the side view.
SteveWMD : Rudder Bug : 04/01/2019

This so called new drawing does not carry the original "nose lines".
Gene Rock : Rudder Bug : 04/01/2019

The Miss Martha was designed by me in 1979. This was in the earliest days of fun-fly competition, for which this plane was designed. The plans here are not original, but do appear to follow the original outline except for the rudder - I don't know where that came from. The original airfoil has a slight amount of reflex at the trailing edge, but had problems with flutter at high speeds. The cure for the flutter was to add counterbalances at the tips of the ailerons, which consisted of 3/32" music wire and wheel collars for weights. (the original plans showed this). The last MM I built was in the mid 80s, and had an OS 61 four stroke. The best flying ones, IMHO, were ones built very light and with an OS .32.
Bob R : Miss Martha : 03/01/2019

Hey there, Thanks to Tom Solinski for sending in those 18 in span Guillow's WWI plans. I sure built a lot of them when I was a kid. None flew, but they were a good pastime. I'm sure I built the Fokker D8, the Se5a, the Spad, and the first plane I ever 'participated' in building (Dad doing all the real work) was the Sopwith Camel from this series. Here's to 2019!
dfritzke : Fokker D8 : 02/01/2019

To keep it simple and allow for easy detachment of the stab for transport, I did not fit a steerable tail wheel to my model. A quick blast of throttle with some rudder and a little down elevator steers it around on grass OK.
Mike Foister : Miss America : 31/12/2018

By 1955, RC models were not new. The 1937 US Nats had a contest for radio-controlled models. The 1949 British Nats had an RC aerobatic contest. For history on this see For some pre-1955 RC plans on Oz, see Walt Good's 1940 Big Guff (oz7456), 1949 Rudder Bug (oz7009) etc, etc. Using the advanced search, there are currently 88 plans on Oz tagged as RC, dated 1955 or earlier.
SteveWMD : Piper Cub J-3 : 30/12/2018

The magnificent coloured drawing of the full-size aircraft included in the article probably came originally from the reference to [now known as]. However, it was probably enhanced by Paolo because it contains Italian text. On briefly perusing that website it's not easy to find, so if someone is any the wiser then please let me know.
GreggD : Fieseler Storch : 29/12/2018

I really appreciate the other comments and just want to add mine by saying that Paolo is probably the best combination of scientist and artist in the model aircraft field today, whom I'm aware of. Hopefully he's still alive, but if not then there are evidently others carrying on his work because his website contacts includes a laboratory in Italy plus dealers in America, Germany and Japan. Even his website is a scientific and artistic example for others to follow. It's dated 2008, but one of his models on this website is dated 2011, so maybe it's just an oversight. However, I just checked his blog on RCGroups and it says that he joined in 2008 and his last entry was also in 2011. Maybe he's just retired, rather than dead, because a web search of his name says nothing about his death, and check out the attached file. Anyway, whether he's still with us or not, his words at the top of the website are very encouraging to all of us who love scale model aircraft: In order to build a beautiful scale model, you only have to make the most faithful replica of the real plane.
GreggD : Fieseler Storch : 29/12/2018

After Paolo Severin, I would rate Svenson as one of the top modellers today, assuming that he's still alive too. I'm not the only one to say that because the RCM&E article attached to the plan calls it a masterpiece.
GreggD : Fieseler Fi 156 Storch : 29/12/2018

This plan and article are very interesting because of the use of RC back in 1955. The only other one which I've come across in the outer zone about the very early use of RC is the Kirby Motor Tutor (oz2969).
GreggD : Piper Cub J-3 : 29/12/2018

I built the Apex 14 when I was 12 in 1963, at that time living in England. Powered by an ED 1cc diesel, on the tiniest amount of fuel it would fly for miles with me running behind it to see where it landed.
JimmyL-C : Apex Mk14 : 29/12/2018

Since I sent in the plans for the Ace Simple Ultimate I felt I should send you a few pictures of mine [more pics 004-008]. I got this at a swap meet 90% built. I put it on a diet before covering it by removing as much of the heavy ply fuselage sides aft of the wings as I dared. Installed an Enya .15, and after a glowplug change, it ran great and she flies pretty well. 35 years ago I designed an Ultimate loosely based on the Ace All Star and Scratch built that from some of the molded Ace Wings I had. That one has a SuperTigre .23 in it. It's pretty much the same plane, so I am sending a picture of that one too [more pics 009].

15/10 is metric system; 10 is 1 mm and 15 corresponds to 1.5 mm. It means 1.5 mm thick (20/10 for 2 mm, 30/10 for 3 mm and so one); 10 is a reference for 1 mm. It is as logical as feet and inches (and others....) for me!
DenisR : CB 36 : 28/12/2018

Commonly indicated as Mig 19 or Yak 25 in reality it's a fantasy non-existent plane. Based on not good information from the red curtain journalist, this model was kitted by Aurora in scale plastic kit in 1954 and from this kit was drawn this plan (and others). Obviously it's neither a Mig 19 or Yak 25. The real ones are completely different.

The French, for some reason, label all sheet material as a fraction. 15/10 simply means 15 divided by 10, so 1.5 mm. 20/10 would be 2mm and so on.
MHodgson : CB 36 : 26/12/2018

Hi Karl, the thickness of balsa sheets or ply was expressed, in France, in tenth of millimeters. 15/10 is 1.5 mm (approx. 1/16 in). Standards were 10/10, 15/10, 20/10 for balsa. On some plans (peanuts or duration indoors) you could find 5/10, 8/10, or 12/10... Aaah, a long time ago...
Yannick : CB 36 : 26/12/2018

It's covered with transparent orange monokote. The other picture of the framed Yogi is Yogi #2 [more pics 004]. I omitted the optional false ribs to save weight. I was fortunate enough to find another 05 cobalt motor recently. Brand new in the box - and for a cheap price! Yogi #2 will be fitted with a modern brushed ESC and use the more powerful, lighter LIPO batteries instead of the old huge heavy pack of NiCd batteries from years past. It should fly even better than Yogi#1 with the weight savings.

The pilot is G.I. Joe, who is roughly the right scale, and the receiver battery pack is in his chest with the wires running up through the hollow member just behind his seat. The receiver and servos are in the wing roots, receiver and aileron servo on one side, rudder and elevator servos on the other with the receiver antenna running through a nylon tube inside the wing leading edge and out one wing tip. The rudder and ailerons are coupled to deal with adverse yaw. Season's greetings and very best wishes. Thanks again for your wonderful work. Cheers!!

I have made several models from your web-site, including the Red Admiral which was brought to my attention today. It has always been one of my best favourites, ever since it was introduced in The Aero Modeller back in 1958 when I was a mere 15 years old. I have kept it in a position very close to my back burner for all those years, and at last I printed and Sellotaped your plan and built it. A thoroughly enjoyable build it was too. I've attached 4 photos of it here for your amusement, and if you wish fit them in with your collection [more pics 007-010].

Apologies for the confusion. It turns out the plan previously in this slot was a duplicate of the Ron Warring Hobbies Floatplane (oz7602). Many thanks to JonPutnam for spotting this. Have removed the Noname Rubber Floatplane plan now and replaced it with this Minuteman Team Racer plan.
SteveWMD : Minuteman II : 18/12/2018

I'm intrigued by the fact that this plan uses a convex aerofoil, but the KielKraft plan oz1033 uses an undercambered aerofoil. The latter would have been used by the full-size aircraft, so it's strange that a German model doesn't use it.

Question on the Ranger 30 plans: Do you know the origin of these plans? They're quite a bit different than the model I build 40 years ago, and they're quite a bit different than what you see in the instructions. I'm wondering if they're either historical drawings, or someone's drawings based on a model. I cut out the pieces in mat board and found several differences between it and the original, and several pieces that just don't fit together. Thanks for posting these, and other plans, it's great to see the old models available.

Reading the text which comes with the plan, I noted that Keith Humber, in comparing what he could do with his model (loops, stalls and spins etc.) with the full size Eagle, remarked that he doubted if the full size was robust enough for such maneouvres. When I belonged to the Westcott Club in Bucks., in the 60s, our 'Swallow' was often looped, spun and rolled. Even our S 21 'Sedburgh' would loop and spin! Whilst under instruction in the 'S 21', my instructor insisted that I learned to stall and spin and even, one fine cloudless day after we achieved a high launch, demonstrated the looping ability of that big 2-seater!

Davidterrell80 : Viewpoint 4 : 28/11/2018

I am trying to learn to fly rc models. The model is not balanced with the rc equipment only so I had to put some lead in the nose, about 100g. And the Cox .049 is perfect for this glider. My teacher told me that gliders or powered gliders with .049 engines or similar are very easy to fly and learn. It took it very well with a lot of wind........ and I crashed it! It was a really windy day. I crashed it with a wall!!!! I almost crashed a teacher's car! (I was at the school sports field with my teacher.) But I think that I am very lucky because the Hi-Fly didn't have serious breaks. It only broke the left ply dihedral reinforcement and the hard balsa nose block.
GJoseRosalesRuiz : Hi-Fly : 27/11/2018

Yes, the fuselage is welded from stainless steel tubing, forming an exact scale replica of the full size machine. Without using any jig, or indeed any 1:1 drawings, according to the article. It's an incredibly skilful and complex build, using techniques that the rest of us would simply describe as magic., there are no formers. Although he does sell a complete kit, so there must be some way of replicating the build.

AR : Pacific Ace : 26/11/2018

Great stuff, but as a "newbie", I have a rather fundamental question: I would like to build a replica "flying" model, ideally a biplane (Fokker D.VII?), at 1:72 scale. This equates to a wingspan of no more than 4 inches. With an electric motor and battery weighing no more than 10 grams altogether, all-up weight (i.e. wing loading) doesn't seem to be the limiting factor, but ... It seems to be the "stickiness" of the air at this scale that is the problem. There seem to be no RTF models at this scale. Has anyone tried to tackle this? How would the speed and pitch of a "scale" airscrew bear on this? I am not looking for "FROG", and RTP would be perfectly acceptable. Ho hum, I may end up just having to experiment ....

Enclosed find a picture of an odd experience with my "Old Timer" (RCM ref:1026). Since she is floater, I have to initiate approach farther to the runway than usual. On final, the motor quit at a low altitude, and way far from the runway. Hit a pole and fell behind a line of trees. After receiving condolences from my friends at the club, we went with a big plastic bag to retrieve the remaining pieces. To our surprise, she was proudly resting on the roof of a hen house, with only a broken prop [more pics 008]. No one saw how she managed to land. Now I have learned to always track with a stop watch the remaining battery time in flight, so I may have plenty of time to even perform a couple of go arounds, and fly safely :-D

Hi folks, here are a few pictures of my Curtiss Jenny from the Comet plans on Outerzone [model photo & more pics 004, 005]. I built it extra light with split ribs, balsa wheels and laminated tail surfaces with the intent to fly it this summer. But, I have to admit, I'm thinking of letting it be a Hanger Queen for a while first. Thanks for making these old plans available again!

Hi, I would love to get a copy of g code or stl laser cutter file as I have access to a laser cutter.

Hi Geoff, I think you're putting the cart ahead of the horse as the Fi 156 slats were fixed. No extend/retract mechanism, just bolted in open position. Regarding fuselage formers, the original had none of these, the fuselage was welded metal tube - I'm not sure of the material right now - and Mr Severin followed the original.

Does anyone have a link to a build thread for this one? Thanks.

The C of G is not shown on the plan or text. I have started building and would appreciate your help. Thanks.

I had been painting my glider last week, it was my first time at painting a model so it it isn't perfect but it has a good look [model photo & more pics 011, 012]. It's finished now so the next step is: FLY!!! I put Futaba standart servos, FM radio transmitter and a AA battery pack. I hope the weather gets better here, it was so rainy these days. I will fly it in the school with my teacher, an experienced modeler, he helped me with the build of the Hi Fly, there is a big sport field there. In the last photo I am with my teacher [more pics 013].

If anyone can help Geoff, please chip in here via Comments. He's also happy to engage in direct email correspondence, so let me know if you want me to put you in touch.

Have always LIKED this airplane and would love to build this model. It seems to lack any detail on fuselage formers, though, so it's hard to determine fuselage cross sections at various stations front to rear. Is there another plan sheet that's missing ? Any additional detail on a mechanism to open leading edge slats in concert with trailing edge flaps (maybe a cam arrangement to add slats at >20 degrees of trailing edge flaps) also would be useful/helpful. Or I could set up slats on a separate channel, perhaps. I would plan to make it a 6-channel R/C model - rudder, elevator, ailerons, engine speed, flaps/slats and lights. Many thanks for any added info.

Beautiful old design.

Some pictures for you, hope you like them [model photo & more pics 003-005].

Concerning the previous comments I would like to add that Neville Shute was also one of the brains (brains?) behind the Great Panjandrum for Lord Mountbatten. This was one top-secret weapon too be displayed in plain sight to distract the Germans. This is one of its least embarrassing videos: . And my thanks to Joel Cimmino, he has a firmer seat than what's above in my private Hall of Fame.
