I have scanned an 2 part article from the FMT Magazin 10/94 + 11/94 (German Instruction with Scale Documentation) for the beautiful Zlin 125 Sohaj Glider (J.Petran) Plan ID. oz 3279 [see supplementary file]. This plan (2 parts) was also in this magazine. Enjoy!

Included are pictures of my recently build Jet 40 from a 30 years old kit [more pics 006-009]. Not for a 0.40 engine but transformed for brushless outrunner 3548 700KV with a 5s 3000mAh battery. Also included a real cockpit with pilot! Flies a lot better than with the methanol engine!!!!!!! I also downloaded the plan from your site, because I have not saved the wing ribs!!!!!!!! And that gives a problem to build an other one........... Egrtz and a lot of thanks!

Having compared the pdf of Graupner?s X1200 to parts from an original kit, I found the Outerzone pdf to be slightly off scale. Having the pdf printed out at 98% solved the problem though. Regards and many many thanks for your excellent work!

Plan Mit. a5n2a Claude by Nate Sterman. I'm in the process of building this model [more pics 003]. Construction notes: 1. bulkhead 4T is too tall and upper stringer notches not wide enough. I removed the center top, widened the stringer locations. 2. cockpit panes a little too wide at base. I trimmed same. 3. LG strut location not indicated on plan. I used other sources. I'm 77 yrs and been able to continue using the razor blade on printed sheet. THANKS Outerzone.

Just finished an electric version of Owen Kampen's Half A Pacer [more pics 005]. I had a set of Ace Wings, so I put them to use. Did not build in the rudder control, as per the 1974 original. Hope to fly it soon.

Hi Mary, here are 2 photos of the Mini Robot MK-V I am building from the plan of the same down loaded from the Outerzone [more pics 003, 004]. It's an adaptation from the Veron Mini Robot as shown on the plan. Must say the thing is build like a tank - spruce spars and a ply D box wing. Perhaps it did not only sport German war marking but actually went to war? With some apprehension I build my version lighter. Funny how it's 1970s Germanized all the way - those kits are known to be as going down the design road of 'heavy build' and 'fast flying' as result and all that weight needs to come to a standstill on an unintentional impact with any solid object as Terrafirma might well be. As opposed to lightweight, often found in Veron kits, that is still strong enough and by no means slows down a fast engine and just saves you from closing a hole in the ground and engine to dig out on impact. Well I shall see if my apprehension is based on lack of insight this designer had or me when flying has commenced. He seems a very experienced designer, but saying that why is there no dihedral brace shown on the plan? Sure it needs that. With all these meandering thoughts I am very curious to know what the original Veron Mini Robot plan looks like. Perhaps a kit collector will become adventurous and let his plan step out of the box with accompanied thoughts and send a scan of it to the Outerzone and so the world to see.

Steve, I found the following comment about the Shoestring (ID 1923) in the Feb 1966 issue's editorial, By Don Dewey: -- "You can't get rid of me that easy. I just remembered a note that Carl Goldberg wanted passed on to youse guys that are building the Shoestring, featured in last month's issue." -- "The wing breakaway plate as shown on the plan is 1/2in wide and will break in the vicinity of 45 pounds of pull. This amounts to around 11 G's. However, since it has been pointed out that some fellows may produce far higher G's than contemplated by running the ship faster and making sharper pullouts, it may be advisable to provide for a higher breaking load. Accordingly, Carl recommends that the breakaway plate go up to 1in. Since the holes remain the same, the breaking load with the larger plate goes up to approximately 105 pounds, according to test results. This is better than 25 G's, dad, and if you need more than that, forget it. By the way, the cross member which is 1/4 x 1/2in basswood, should be changed to 5/16 x 3/8 birch. Okay?" -- Don Dewey, Feb 1966, RCM.

Here are some pictures of my Double Jabberwock, a Don Srull design I downloaded from Outerzone [more pics 005-009]. The plane is equipped with a Hobby People 2814/06, A .15 glow equivalent. 11/5.5 APC prop with an ElectriFly 25 amp Silver Series ESC. Flying weight with a three cell, 2200 mah pack is 46 ounces. This produces an 8 1/2 ounce/sq. ft. wing loading. Performance is outstanding with glides that seem to last forever. Excellent thermally abilities. LED lights installed internally for night flying. Covered with Top Flight transparent yellow Monokote. Visibility is amazing. Working on The Yogi now. Another Don Srull design.

Here are a couple of photos of the RCM Sportster that I built from your plans, RCM 543, OuterzoneID: 6143 [more pics 003, 004]. Converted to electric. It flies great with a Propdrive 3536-1400KV motor, APC 10x5E prop, 50 amp ESC, and a 2200 mah battery. Flies for about 8 minutes with throttle management. Needed 3 oz weight in the nose to balance (I moved the rudder and elevator servos to the rear of the plane). Weighs 3-1/4 pounds ready to fly. Thank you for hosting Outerzone!

Hello Steve, I built this A6M Zero from Dave Platt plan and semi kit [more pics 003-010]. This war plane is the easiest war plane I fly for such a long time. Easy handle, track straight with its wide landing gear, smooth, no bad habit and is a very nice thru scale line plane to build also.

Hi Steve, I built this model back in high school, probably 1951 or '52. Can't remember what motor, could have been a Frog 150. Made a colossal noise with the modelspan covered fuselage drumming. I think it had a celluloid fuel tank. Didn't last long, typical of my models in those days. Thanks for this wonderful repository of memories.

Hello Outerzone Friends. Some modifications were made to the Don Condon Cherokee Arrows 200 plan, such as increasing the wingspan to 76 in, length to 53 in and a landing gear fixed [more pics 005-011]. The wing is now a tapered wing, no more a Hershey bar wing. The scaled interior as such: coutains, control panel, etc. Thank you all Outerzone! From Brasilia - Brazil.
SergioFloripesFigueira : Cherokee Arrow 200 : 03/10/2017

I built this plane from the kit 30 years ago. Please advise builders to strengthen the landing gear mounts and try not to thin the leading edge to much. Mine flew beautifully but would hunt around on landing especially with flaps. Not until I added leading edge cuffs to the tips did it behave and become a great airplane. Consider modifying airfoil to correct this situation. It has lots of wing area and is realistic at the 9 pound weight mine weighed.

Here is the structure of my third C. B 24 [more pics 004, 005]. A rubber band model, equipped with a small electric motor. Anyway good to fly in open field. With a 450 mA 2 cells BATTERY. It flies more than 15 minutes. Very small model, but still quite fun. Thanks for OUTER ZONE.
JulienVermeire : CB 24 : 03/10/2017

The odd slant on the windshield dates back earlier than the Mystery Ship. The Vultee V-1 had this feature in 1934, as did the early Boeing 247, some Miles aircraft such as the M.3A Falcon Major of 1935, and the Stinson Model A (1934). I'm sure there were many more. Some photos and drawings of the Spartan Cruiser II show what appears to be a perfectly vertical windscreen.

Correct name is Fidia Piattelli Yaakov - Born in Roma 1907, Died in Tel Aviv 1957 due to gun shot while trying to stop a rape in a cinema. He was a modeller, aeronautical engineer in Officine Reggiane and an artist too.

Mary : Peres I : 29/09/2017

The initials stand for Ing. (engineer) Fidia (apparently a Greek name) Piattelli. He was an Italian aeromodeller and aeronautical engineer. He was imprisoned in WW2 for being Jewish. After the war he went to Israel and continued his career. He made some unusual and beautiful model designs.
Pit : Peres I : 29/09/2017

Many thanks for posting this cleaned up plan of an old favorite. The usual caveats should be heeded, as with any build; the right wing panel is significantly longer than the left side panel, and the discrepancy carries over to the stabilizer as well, although being of shorter span, it is not as obvious. I actually have a copy of this plan, ordered many moons ago from John Pond. I should check that copy for symmetry.
DavidD : Piper Tri-Pacer : 29/09/2017

The plan identifies the designer as F.J. Piattelli, whereas the article credits (Dr.) I.F. Piattelli. It's a minor point, but does anyone know which is correct?
Mary : Peres I : 29/09/2017

A little more (trivial?) information: the plan showing the prototype Draken (dragon) and the real thing (the prototype) is on display at Svedino's Automobile and Aviation Museum in southern Sweden. A museum well worth visiting.

NorbertoStabile : Tom : 25/09/2017

I built a model of this from M.A.P. plans in 1964 and remember well the first flight. After adding four (imperial) pennies as noseweight for balance, a beautiful straight and very gentle descent of something like 100 feet was achieved even though launched only from shoulder height. I think this aircraft has very elegant lines.

Little V is a lovely plane and a nice easy build. It is a pretty good flyer for a "ruddervator" v-tail, once I'd used the designed dihedral. I built it too flat at first for the rudder to be effective but after test flights showed the problem I sawed the wing in two and re-joined it with the correct angle and it now turns well. It's robust, too, as it's easily survived some harsh landings on the South Downs. My only I wish is that I had added a ballast box under the servos as penetration could be better. My photos attached for the web site of the plane and my take on the sliding servo tray [more pics 009-011]. I tried to copy covering design of the original but used tissue and Ezedope instead of solarfilm - so perhaps even more retro than the original? So, thanks for putting this plan on Outerzone!

Here are a few pictures of my Invader, throughout the ages ;<) [more pics 006-012]. At first (in 2010), it flew at 38 oz. with an Enya 15-IV, and very well at that. Then in 2014 after much flying, I thought I would make it a bit more aerobatic if I fitted a Supertigre G20/23. There was not that much difference, the silencer being quite restrictive. A Fox 25 took its place and it began to move along. Then this year (2017) I was given a Supertigre S29 with the larger silencer, with which it really scoots at 50 oz. flying weight and will loop from level flight when applying full throttle. But during all this time, I could not make it take off because it would ground loop. So, I added a nosewheel and now I really enjoy flying the Invader. It is such an incredibly versatile workhorse, yet definitely very agile, so much fun. It is all the original advertisement claimed. Present trim is with -2.5 degree tailplane incidence (instead of 0 degree - I cut 1/4" off the rear of the tailplane saddle) and C.G. moved forward at 24% (slightly in front of the wing spar). Engine is at 0 degree down thrust and 1 degree right thrust. Next and probably final step will be to put some engine up thrust to tighten the loops a bit. Thanks again for the Outerzone, best modelling regards.
JMP_blackfoot : Invader : 18/09/2017

Ah, thanks Pit, of course - that makes sense. Correct at 56in span, then.
SteveWMD : Heinkel he 162 : 17/09/2017

The difference in wingspan is due to the angled wingtip on the finished model and the tip shown flat (for true shape) in the elevation wing plan. It is all correct, to me.
Pit : Heinkel he 162 : 17/09/2017

Note this one looks to be slightly out of scale - thanks to DerrickScott for checking - the wingspan measures 60in, but the title block says it is a 56in plan.
SteveWMD : Heinkel he 162 : 17/09/2017

I found this plan in the local model shop's bargain bin some time in the early 80s and took it home to build as a radio trainer. I flew it very successfully for several years on an AM10 diesel which had plenty of stoke, with 2 channel R/C. As the blurb says this is a very light model and I would make 2 recommendations from my personal experience. The tailplane is of very light construction as designed but is also quite vulnerable where it is positioned in a taildragger. Eventually I replaced mine with a 3/16 sheet version with a couple of keys inset across the grain. I had no further problems with it. The second recommendation is the wing. If like me you can't resist a few loops and wingovers with pretty much anything you fly it would be worth webbing the upper and lower main spars. After several years of this sort of treatment I was happily flying S&L one day when the wings just clapped hands and it was all over.

I have a few photos of the Lanzo Bomber [more pics 003-005]. It used to be free flight, once landed in the water even. It took about an hour for it to float to shore, almost no wind. Later due to loss of flying site I converted it to r.c. with the same engine it used for free light. Not flown it after conversion yet.

Well spotted Mark. My mistake - this was mentioned, but I somehow missed out Marcelo's note re moving the gear location. Have added it into the 'About' section now.
SteveWMD : Pucara : 14/09/2017

Hi, looks like a nice model - but the plan does not tie up with Marcello's picture. The u/c on the actual model is one bay forward of the wing not at the leading edge, Something to do with ground stability & cg I guess, its a long nose. Perhaps Marcello would like to comment. regards, MarkM.

Hi Steve, this is the Competitor newly kitted by a local producer, parts are laser cut [more pics 010]. This bird has a lot of good memories for Iranian old modelers.
EhsanM : Competitor : 14/09/2017

I remember this magazine but never considered building the model because of its small size, waaaay too tiny for my radio gear. I had a Berkeley Aero-Trol, bought mail order from America's Hobby Center in New York, and it turned out to be a hopeless piece of crap. It featured a single tube receiver, multiple expensive batteries and a crude escapement that never worked, even on the bench. Besides that, the whole concept was out of date by at least ten years, AHC dumping the remains at a cheap price. Don't remember the cost but it was a big wasted chunk of my paper route money. Another year went by until I was able to acquire a real, working R/C system. But that's not the subject, it's the magazine listed as American Aircraft Modeler, incorrect for 1961. For many years, the title was American Modeler, so why the change? In the early to mid sixties, the slot car phenomenon hit the modeling world, and slot car tracks sprouted like weeds in strip malls everywhere. Some of the model magazines carried a couple of pages on slot cars and a few ads too, but not like American Modeler, who rapidly went all-out into the slot car craze. Soon, that's all there was, no airplanes were to found inside the covers. Hobby shop sales dropped to zero among modelers and subscriptions plummeted. Then the predictable came to pass, the go-fast boys took over and ruined the event like they always do. It got to the point where, if you wanted to be competitive with your slot car, you had to send your cheap little Mabuchi motor off to a guru in California to get it reworked for more power. At that time, my brother, who ran slot cars, packed his in and wished them well. Sometime about '65 or '66, the entire slot car movement died suddenly, tracks shut down and it was all over. Somewhere in the USA there must be a slot car track still in use, frequented by aging hippies clad in ponytails and bell bottoms, but I haven't seen one in decades. Now, what did this do for American Modeler, without ad revenue from defunct slot producers, and no readers from the airplane guys? Simple, just change your name to American Aircraft Modeler and say "never mind". It didn't work of course, modelers being a non-forgiving bunch, not willing to risk another worthless subscription. AAM hung on for another couple of years but eventually faded into obscurity after their financing ran out. And that's the rest of the story, with credit to Paul Harvey.

EdShearer : Schweizer 1-30 : 13/09/2017

I built one of these back around 1990 and powered it with an OS 48 Surpass 4 stroke. This seemed like an ideal power plant giving plenty of performance (though not compared to today's 3D style of flying of course) and the CG was perfect with no additional trim ballast required. The Sportster Bipe is a beautiful flying aircraft that is quite stable and easy to land yet can be tossed around to give a nice aerobatic performance and being a biplane it looks larger in the air than it actually is. It's a real pity that Great Planes discontinued the model. Definitely worth the effort of scratch building if you want one.

Hello friends, I commend your commitment to the most beautiful hobby of all. I'm sending you pictures of my 2nd Kombat King [more pics 004, 005]. After the loss of the 1st one I had to build it again. He flies really well.
CarlMichaelNowak : King Kombat : 12/09/2017

I was wondering when this aircraft would surface. When I was a young teen back in the early 60s plans for this plane were included in one of the model magazines I subscribed to ... probably Model Airplane News. As they were only magazine page size I took a few days to draft them up to the 24 inch span and then started scratch building. Kids couldn't afford RC gear in those days as it was huge money so I built it up as a free flight. Then I got my driver's license so it sat around for a few years as model planes took a back seat. I gave it to a young kid I knew who put in a Baby Bee .049 and I saw it fly once. It was a pretty looking biplane with nice proportions that flew reasonably well. Would probably make a nice electric three channel for today's use, or put ailerons on the lower wing.
SteveC : Radi-O-Too : 11/09/2017

I have just measured the original plan I sent to OZ and I find: width: 33.85ins, height: 21.50ins. Wing chord: 6ins, wing rib: 5.33 (or perhaps more exactly: 5.325ins). I think it would be a good idea if the exact dimensions of all "full size", (e.g. kit) plans, were published each time they are put up rather than just relying on wing-span.

I managed to find a drawing of the Swan with wing rib and tail rib sections, and working on the wing ribs being spaced at 2 inches was able to scale up OK using GIMP. This link gives many Swan diagrams which should help anyone building her:,+Mercury+kit. Not sure how accurate my guesses have been, but I ended up with the wing chord at 6 inches and the main wing ribs at 5.33 inches. Overall size of the plan before putting through Posterasor is width 34.11" by 21.42". Hope this is of help. Beautiful looking aeroplane.
MalcolmJ : Swan : 10/09/2017

I first built this model in 2009. After my first flight I wrote some comments [see supplementary file]. I'm currently re-building the model as because of an error on my part the first one finished up in pieces. In contrast to the first model, I'm using Century jets electric retracts. I'm using the same Saito motors but mounted in the 2s position. As well, I'm covering the model in 1/2 oz fibreglass cloth using Deluxe Products EZE Kote. I would strongly encourage anyone to have a go at this build. It's easy to build and easy to fly. Just pay attention to engine reliability.
SteveSutherland : A-26 Invader : 10/09/2017

Hello, here are 3 photos of my KK Ajax converted to run on a BR1103 motor, with 400 ma 7.4v battery [more pics 004-006]. As explained previously, when I built the wings from the plan originally, none of the 3 wing sections matched up, so I re did the wing plan by using the port wing and then inverting it on the printer for use as a mirror image on the stbd wing, and then drew a new centre section to build the whole wing in one piece. As you will see in the photos I added two ribs in the ctr section to take the load of the elastic bands holding the wing on, and changed the LE to bamboo to stop the bands crushing the LE. I am not sure if I am going bonkers with old age but the wing centre section seemed incredibly weak to be held on to the fuselage with rubber bands. I ended up adding the 2 extra ribs to transfer the load on to the fuselage longerons, as well as a stub spar at the ribs deepest section to take the load of the unsupported tissue covering. What I cannot understand is that, as the plan has been around since 1939 and flown very successfully, why have I had so much trouble with the balsa being crushed by the mounting bands?? Anyone got any ideas? Any way the wing looks OK for a test fly this coming Sunday morning, 10th September 2017. Fingers crossed. I'll let you know how it goes, and hope the CG is in the right place.

Suggestion rather than a correction: I built my Aquila about 1978 and before starting the project took the plans to a meeting of my model club and asked if there were any modifications I should make.

I had to laugh at the ad copy for this model, "and can be powered by any Rogers or other first class motor". As any old timer knows, the Rogers is widely acclaimed as one of the worst pieces of crap ever made. The vast majority never ran at all, and the ones that did, broke in and wore out at the same time. Thousands of poor kids wasted their paper route and lawn cutting money on one of these disappointments instead of a Bantam or Ohlsson. There's a sucker born every minute.

A few pictures of the a Sweet Stik 40 I built following (approximately) the later version by Pete Frankenthal [more pics 003-007]. Power is an OS Max 46 AX, radio is a Futaba Skysport 4. Changes made were building the wing flat, utilizing two servos in the wing instead of torque rods, using wing bolts to hold the wing on, and substituting 3/16 balsa for the fuselage sides and bottom instead of using lite ply. The servos were installed 3 abreast as shown on the plans, there was enough room behind the servos to install a flat battery pack. This was a necessity to balance the plane, as the plane came out quite nose heavy with the set-up shown on the plans, which I attribute to the lighter engines of the day when the plane was originally designed. It flies very fast, smooth, and is capable of doing most aerobatics on the power setup shown.

Hi Mary - I thought you would like this photo of Don Anderson which was taken in my house in Detroit in 1972 [more pics 004]. Don was a test engineer in the General Motors' Pontiac Motor Division's Bumper Test Laboratory in Pontiac, Michigan. I was on a 1 year working assignment as a Body Engineer from Vauxhall Motors in England. This included two work experience periods and two at the General Motors Institute in Flint. I met Don during the second work period finding out about 5 mph bumper tests and we spent a lot of time talking about model aircraft. Don went on to set up 'Great Planes'. I don't know what model he had on his lap, but it certainly has the look of models he designed later in life for Great Planes.

Steve and Mary, Thanks for your efforts with Outerzone, a fantastic website that I check frequently. Attached is the Komander instruction booklet you may elect to post [see supplementary file]. I still have a flyable Komander that is about 40 years old. The canopy attachment was tricky, I laid up a few layers of fiberglass on the wing upper surface, like making form fitting gear doors, to completely seal the canopy and stiffen it, This was then trimmed and glued to aft end of canopy to create a canopy module.

It is not so much a correction but an error on the printed plan. The Ace which is the Elfs larger brother has the leading edge swept back and I believe that so should the Elf. There has been an error in my opinion from whoever drew it. Regards,

Hi Steve - concerning C.H.Grant, I always understood that he was more a theorist (in aeromodelling) rather than a designer or builder. Now some of his theories are considered wrong. I have two books of his - none of the published plans or model photos were credited to him, and in the foreword page he regularly thanks many famous modellers of the period for contributing with plans and photos. For me KG1 is the only published plan designed by Grant, who asked Kovel for the construction. I feel Bellanca is from Kovel, but probably it's not inked by him. It's possible to find some construction similarities with Kovel's Waco biplane in March 1934 MAN that prove the Bellanca ownership. This plan too was not inked by Kovel.
Pit : Bellanca Aircruiser : 25/08/2017

I suspect this plan was designed by Charles Grant, and that Joseph Kovel simply wrote the article pages to go with it, rather than being the designer. Can anyone confirm this? Thanks.
SteveWMD : Bellanca Aircruiser : 24/08/2017

Hi Steve, I am building the Ajax and am installing a BR1103 electric motor. I ran into problems building the wing in 3 sections as per the plan. Building the wing in this way the 3 seperate sections do not line up. To get round this, I printed the port wing and then printed a reversed port wing, so the two outer wing section matched up. I then laid the two outer sections on the building board with a blank piece of paper between them and drew the centre section with a pencil and ruler. This has worked OK with the finished wing balancing on the centre rib. When I put the wing on the fuselage the wing rocks from side to side as it balances on the wing centre rib, but has no support where it contacts the fuselage sides. I suppose infill under the LE above the cabin wind screen would cure the problem, but I added a 'stub' spar on the deepest section of the wing running through the centre rib and two adjacent ribs.. I hope to have her finished by next week and will send some pics.

SteveWMD : Fly-Boy : 21/08/2017

Hi - I just wanted to add a bit of info about the Fly-Boy as I learned to fly with one of these in the mid-nineties, flying it probably around a thousand times if not more. I also flew two others. Mine was powered by an OS.15 which was more than enough power, I also flew one powered by a 'hot' 25 and another with an OS.35 in the nose. With the OS.35 it was heavy and the most powerful version I flew was by far and away the worst handling of the three. The version powered by the OS.25 was also overpowered and more of a handful than the 15 powered example. As a primary trainer this is not a great design, it has a habit of snap rolling at any speed if excessive elevator is used (even with the prescribed throws), it also spins like a top. As a three channel aerobatic model it was very capable though, the only thing that it struggled with was sustained inverted flight but it would roll very well just on rudder, looped smartly and spins were easy to enter and recover from. It could be flown slowly but great care had to be taken with the elevator, if stalled at low speed and in any sort of turn, it would spin straight in. Structurally there are a couple of points that could be improved: The arrangement of the fuselage with plywood pre-cut panels featuring those big open areas aft of the C of G isn't great when covered with iron on film. There's too much movement in the structure and no matter what, the covering over those parts of the fuselage will sag and require re-tightening on a fairly regular basis. If building one, I would put in some diagonals to stiffen these areas up and provide additional area to stick the covering to. 1/8th square would be adequate and add very little weight. The undercarriage as designed is also a weak point. It will spread and splay. The version I flew with the 25 in the nose was the second example built by the owner and he had added a second undercarriage leg and a rubber band bungee arrangement. This was a massive improvement. Build this one as light as possible, don't overpower it and you'll find you've got a fun, if snappy, three channel sports model. If you want to learn to fly from scratch, build a Super Sixty (just beef up the centre section braces if you do go that route)! Hope this helps somebody.

Hi, Do the rib patterns match up with the plans? I have checked each one and it seems that they do not, being too long. Nice plan though and very interesting. It looks as though the centre section is untwisted. I have one on the board now which is 170 inches with a centre section untwisted. The outer section is twisted to 8 degs with a further 3 degs aerodynamic twist. It seems too much to me but I hope that my numbers are correct. I wonder if there will be a tuck under problem with all that washout!! The model is electric launched. Regards,

I've lusted after this design since I first saw it published in RCM. As a member of the USAF with but two stripes on my arm, there was no way I could afford the required radio equipment. The Digicon radio set it used sold for about $1000 in 1966 non-inflated dollars. Doug Spreng and his buddy Don Mathes were the creators of that system, the first in the world that used their revolutionary servo design, instantly copied by all the other radio makers. Problems doomed the Digicon to a short commercial life but others used the servo circuit with success. The exact same system is used today in the vast majority of current servos.

I must say the QB 20L is a wonderful model, very stable yet responsive. I built one almost 30 years ago, in 1988 to be precise, from the kit. Powered by an OS 25FP it could do all the usual 'club' aerobatics - rolls, loopings and the combinations thereof. The only thing it did less well was the stall turn as, no matter what I tried, it would always 'snake' a little on the downwards leg - maybe it needed less dihedral/more fin and rudder area?? But the things I liked most were the take-offs and landings - with careful use of throttle, one could balance the model on its main wheels, not letting the nose wheel touch the ground for a couple dozen yards. In fact, one of the enclosed photos shows it doing that 'stunt'. I still have that model in my attic, so one day... Well, there you have it - another group of grainy photos from Portugal. All the very best to you both; thank you for your work - and for the joy you give us, true aeromodellers, every single day (yes, I make a point of getting my 'Outerzone/RC Library' daily 'fix'!).

In France, this plane is a legend ... and it's the same for the SVENSON kit !

Does anyone have the article for this one?

I've built this one: it's complete. It looks a bit quirky on the drawing but once built it looks surprisingly attractive.

Exactly it's a D.H. 83 Fox Moth, it seems no mention about engine size.

I have just built from your plan an AIRKNOCKER to use at OT competition here in Sweden. Here are some images of my model [more pics 007-009].

Sturdy? This was my first plane, printed wing ribs and all. Glide was fine .. (we did that in those days .. ) Sadly, the southerly wind blowing across the marsh was quite lively, but as a determined 14 year old , I was keen that my masterpiece should fly. And fly it did, the AM 15 howling, .. one gigantic loop, way above the tops of the pylons and very nearly starting another .. but terra firma intervened .. not by much, but enough .. I still have the diesel, thirty bob from the secondhand shop from a big save with my pocket money.

I've never heard about a "1947 champion", but what was famous was the "1946 Champion" of 111 inch w/s. I think this is a reduced version of the 1946 version that was the final evolution of the "1943 Champion" There's more at

I have attached 2 photos of my WACO Coastguard for your website [more pics 003, 004]. Thanks for all that you do.

Hi Mary - here are two shots for the Voodoo plan [more pics 003, 004].
EdShearer : Voodoo : 31/07/2017

Built by Keith and Cole Bryant in Lancaster, Ohio [more pics 004]. Saito .80 for power.

The RCM Stuka is quite similar: flaps travel - 30 degrees, aileron travel +20 degrees up and -20 degrees down, elevator and rudder not specified but as usual not more than 30 degrees up or down and left/right.
Pit : Junkers Ju 87b Stuka : 29/07/2017

I have built this JU-87 Stuka from your plans but I could not find the aileron, elevator and rudder movement in mm in order to get it ready for flight. I would be grateful if you could sent me the above details. Regards,

Use the wing plan for the Dick's Dream oz5747, and build two constant chord center sections using the root rib. Easy. The Ace airfoil is usually considered to be a NACA 2414 but a 2412 is probably a better thickness to go with (12% vs 14%) Especially for a glider.

This design was built around using the pre-formed Ace Foam Wing. You could build a replacement from balsa using the Ace Foam Wing (oz8557) plan thanks to AndyKunz, if you wanted to go that route.

Here are two photos of Scientific's American Boy, built by Phil Page [more pics 005, 006]. It originally was painted and decaled as per the box art.

Hi Mary - An old well used model with a Fox .15 [more pics 003, 004]. Our club contest stunt flier wanted to fly it as he had flown both the full size Nobler from the kit and the Chinese ARF. After doing the pattern, he said "pretty good".
EdShearer : Jr Nobler : 27/07/2017

Here are a couple of photos of an old Mustunt II [more pics 006, 007]. It still flies well with a Fox .35. The cowling is lost.
EdShearer : Mustunt : 27/07/2017

Do you have any info for a built up wing. Ribs specifically. Or possibly a wing kit?
JohnL : Ace High : 27/07/2017

I am an experienced scratch builder and these plans showed fuselage former's and wing trailing edge were not the same as stated on the plans as used on the finished model , also lacking on wing to fuselage connection. I started this model then shelved for another day due to the inconsistencies in the plans. These plans should either be removed or amended to show the changes made that were required to complete the model. the author of these plans has a blog on rc groups showing these changes. thank you

Hello, I thought I'd share a few pictures of the "Flash" I built from your website [more pics 003, 004]. The "Flash" is a fantastic flying model! I took a few liberties during the build, namely the wing and strut attachments. Great website for those who like to build!
