Super Sportster 40 mk2

This plan is a modernization / redesign of the Great Planes Super Sportster 40 that was immensely popular in the mid 90's. My intent with the redesign/update was to convert the plane to electric and to modernize the parts so they are ready to go for laser cutting. I have drawn this up over the original Don Anderson plan, to keep the overall shape of the aircraft the same. The parts and build process are all new. I have not built this model yet, but am planning to build it over the fall. ...

Aeronca C-3

The Aeronca C-3 was a light plane built by the Aeronautical Corporation of America in the United States during the 1930s. Its design was derived from the Aeronca C-2. Introduced in 1931, it featured room for a passenger seated next to the pilot. Powered by a new 36 hp (27 kW) Aeronca E-113 engine, the seating configuration made flight training much easier and many Aeronca owners often took to the skies with only five hours of instruction—largely because of the C-3's predictable flying...

A/Wonder A1

Oregon's Bob Stalick designed the A/Wonder for the A1 towline glider free flight event. Bob, a lifelong leader in the National Free Flight Society, has utilized the Jedelsky approach for the wing: all-balsa construction with 1/4" balsa for the forward wing sections, 1/16" balsa for the rear wing sections, braced with triangular sheet balsa ribs that provide alignment and flow straightening on the wing's undersurface. This type of construction is surprisingly effective in free flight...

The Folkerts SK-2 was a single-seater racing aircraft designed by Clayton Folkerts for the 1936 National Air Races, racing quite successfully with three first places, two second places, and placed fourth in the Thompson Trophy Races. The planes in the SK series used thin-winged airfoils with spruce spars, manually retracted landing gear, and a variety of high performance engines. The SK-2 was also known as "Sky King Two" and "Toots" and was the predecessor for the more...

Week-ender

Nice little RC .049model. This is a real find. There is very little outside of the magazine it appeared in about this modeller. In my opinion this would be a great little plane to convert to two channel or even three with new little micro-servos and receiver. It should be easy enough for a novice to build may be a little help will be required for some minor shaping and engine mount. It would be a great experiment for an RC throttle. Just fyi: The 049 used is includes the rear engine mounted...

Doug's Trainer

This 4-channel, radio-controlled, trainer is built from pink Insulation foam board, and is electric-powered. By itself, the foam is lightweight but needs reinforcing for expected flight loads and stiffening to keep the wing, rudder, and elevator from flexing, so I have incorporated carbon-fiber tube (wing spar), and carbon-fiber rods (tail feathers). To further help with crash impacts and protect the foam from solvents found in common "rattle-can" spray paints, I have wrapped the...

Polikarpov Po-2

This model is a 1:6 rendition of a Russian utility aircraft produced from 1928 to 1959, and may be the most produced biplane ever with up to 30,000 aircraft claimed! The Po-2 fulfilled several roles including flight training, aerial reconnaissance, and ground attack as a light bomber. Perhaps its most unusual missions were nighttime attacks during WW2 against German ground troops - the plane would glide in at low altitude, engine at idle, and drop bombs on unsuspecting troops before powering...

1948 Glider

Alan Barrister designed the "1948 Glider", a 48" span sport free flight glider launched by towline. The plane would be an easy build with its flat-bottom wing airfoil and single wing spar (the overlapping spars between the main and tip panels will ease wing panel joining). If built for sport free flight use as originally intended, a tip-up horizontal stab dethermalizer would be a prudent measure to prevent flyaways in thermals or breezy weather. The wing mounting shown has...

Grey Ghost

The Grey Ghost was a sleek prototype pylon racer designed in the 1940s by Ed Allenbaugh for the Goodyear racing series. Several of the plane's design details are quite unusual: the pilot flies the plane from a 'prone' position in the slim fuselage, the 'pusher' propeller is driven by aor extension shaft from a mid-mounted engine, and the underslung vertical stab also serves to hold the tail wheel. The plane crashed during its development, killing its pilot, terminating the project. The model...

The plane is an ideal candidate for a 100-150 watt electric propulsion system, and an inexpensive Speed 400 brushed motor would be more than adequate for this lightweight model. The plane would be a 'quick build' with its simple structure, and the wing is built 'flat' without...

Moonco & Crossbow

Moonco and Crossbow are two John Kay designs for CO2 motor sport free flight models. Both span 24" and are all-sheet, using modified "Jedelsky" wing design to provide camber and airfoils. Moonco is a high-wing cabin free flight design while Crossbow is a flying wing with the CO2 motor in a 'pusher' arrangement. Both designs are suitable for beginning modelers and light balsa should be used throughout; painting should be kept to a minimum, just enough for sealing against wet...

Gym Dandy

INDOOR R/C flying has always been a tantalizing thought. You know - sitting in your living room, with a little six inch job buzzing around at your command. Maybe we'll see it one day - in fact, we probably will, in some modified form not in existence. Meanwhile, we have to settle for what is currently available. And it's not too bad, either. Several years ago I published a design, called 'Warpy' (for obvious reasons) which was reasonably successful for that time. Since then, the .010 engine...

A few nerve-wracking lessons are a part of every designer's life and the R/C Intimidator handed Marty some to remember. it's a well-tested, capable stunting machine. Intimidator, by Marty Meyer. When I first started working on this design back in 1969, I had but one thought in mind. I wanted it to look sleek, yet built from a minimum number of parts. I wanted to get away from that usual boxy square look that you find in so many of today's multi airplanes. I was striving for a durable, light and...

Sword

Sword is a British style control-line plane designed for combat or sport flying, powered by a 2.5 cc (.15 CID) or larger engine, glow or diesel. The design is pure British with the horizontal stab and elevator attached to the wing trailing edge. Construction should be fast and easy, usually the case for combat models due to their normal "expendability" in competitive matches. The long nose moment is perplexing as all the "heavy stuff" - the engine and tank - are ahead of...

3d Printed Cessna 152 Kit Includes a mod (an extra part) to allow you to fix the motor from the back side so it does not gets too hot and also includes an extra cowl that instead of the motor fixing has a wide opening to allow air to get in and cool the motor. It´s also advisable to secure/lock the wing with a nylon screw on top. The wing is attached to the fuselage by a sliding rail, this works pretty well to secure the wing but it may slide back so the screw is just a security...

Stinson SR-9 Reliant 1-4 scale

Stinson SR-9 Reliant 1/4 scale by Dick Barron. A real beauty drawn out on 6 sheets including formers and ribs. This is a fairly difficult model to find. Scratch builders will want to have several builds under their belts before attempting a model of this scale and detail. While this model is difficult to find Top Flite makes a very similar 1/3 scale kit which may be better served for the less experienced builder that may want to try their hand at large scale models. The video shows this...

Loffler L-8 Wakefield Winner

East Germany's Joachim Loffler competed in the 1963 Free Flight World Championship, held at Wiener-Neustadt, Austria, with his L-8 Wakefield rubber-powered free flight design, and emerged as the World Champion flying two similar models, one of which is shown here. The design is elegant with its elliptical planform flying surfaces, a fairly long tail moment, and a relatively small horizontal stab area. Compared to today's state-of-art Wakefield (FAI class F1B), the L-8 design isn't cluttered...

Little Joe

Little Joe is a 'cute' low-wing 1/2A sport control-liner designed by Carl Snyder in the early 1950s. The 21" span plane has a attractive racer-like appearance and would be well suited for a Cox reed-valve engine or equivalent power motor, not a high-revving competitive motor such as a TD 049, Holland Hornet, or a CS 049. This editor notes that the plane is built with substantial amounts of 1/32" balsa for wing and fuselage planking. Working with balsa sheet this thin requires extra...

Little Sabre

Little Sabre is a 1/2A sport control-line model, a "sorta scale" of the F-86 Sabre jet, designed by Walt Musciano for Scientific Models in the early 50s. Common to Musciano's numerous other similar aircraft, the 18" span Little Sabre is all-balsa with a hollowed out "balsa log" fuselage and all-sheet flying surfaces. A more practical, and lighter, fuselage would easily be created using a simple 'box' construction or a simple sheet balsa profile fuselage. The drawing...

Magee "Challenger"

The Magee "Challenger" is Peter Miller's whimsical sport free flight model of a 1920s era aircraft, not scale by any means but having a certain pixie-ish personality with its single parasol-mounted wing configuration looking similar to a monoplane wing Jenny biplane. Span is 23" and power is a GM 120 CO2 engine and extremely light building materials are needed to produce a good performing model. The attached Aeromodeller construction article has a delightful (and evidently...

Blizzard

(...) [To make the Blizzard] My first step was to adapt a version of my HI-Tee and Executioner open power models from the 60's. I rescaled them to 36 inches projected and this is what I came up with. The fuselage is of 1/16" triangular section with carbon longerons. The wings are based on the Hi-Tee planform with Executioner semi Geodetic structure. Hardware is coming from Hobby King (various Escs motors and batteries). Fuselage is complete but I left it with a bit of nose overlength to...

Optimo

Optimo was designed in the mid 1950s by Czech modeler Z. Tucek for competition gas-powered free flight use. The plane has a classic look with a high fuselage pylon, elliptical shaped flying surfaces, and slightly undercambered NACA 4409 wing airfoil; in many respects, the Optimo has a strong similarity to Carl Goldberg's Sailplane gas model that was designed and flown in that same era. The model was later modified to incorporate radio-controlled rudder & elevator control, plus throttle...

P51-D MUSTANG

3D Printed P51-D MUSTANG This plane has two possible front sections, the one you see in the images above and one with the inner structure pulled back about 2.5cm. This second front section allows the use os a longer can motor like a D3530 that will be fully enclosed in the fuselage. A D3530 1200 kv with a 3s 2000/2300 mA/h battery is more than enough to fly this plane pretty fast. Lenght: 807mm (31.8in) Wingspan: 992mm (39.1in) Height: 226mm (8.9in) Wing area: 17.1 dm2 Wing...

Mig-3

This is an excellent set of plans and one BIG airplane! While it may not be perfectly scale, it is close. It is 1/4 scale which makes for a an unusually large airplane for only a 3 cubic inch engine. I am downloading the four pages of plans and it is on my list of things to do. I think it will make an excellent scale airplane capable of some mild aerobatics. The full-scale Mig-3 was not considered "successful" as far as fighters go, but we must remember this was the era of the...

Lil Tri Squire

This plan is from a Lil Tri-Squire 1/2A RC trainer kit designed by Vince Micchia in the 1970s. It has a 41 inch wingspan with an approximate ward of 8 1/4 inches. The plans call for Cox TD or medallion.049 glow engine. The plans contain ample information to build this model airplane as the fuselage is rectangular cross-section built of 3/32 sheet balsa with balsa formers. The wing being constant cord of 8 1/4 inches requires one template to trace the wing rib outline onto 3/32 sheet balsa. It's...

Stylus Glider RCM

The Stylus was designed for hand launched thermal flight. Launching is a little different, however. Since the Stylus has such a low wing loading, it is harder to get a high launch than with a heavy glider. But once up in the air, the Stylus flies slower and has a lower sink rate. Flight times in still air seem to compare closely with the other hand launch designs I have seen. Thermal flight is a joy. The slightest wisp of lift is enough to keep Stylus airborne. Turns are very tight and flat....

The history making Sr. Falcon ARF is a sharp, sport airplane built from the blueprints of the classic Sr. Falcon kit. Back in the 60 s & 70 s, the Sr. Falcon was a 60 size airplane. With today's engine technology, the Sr. Falcon performs better than ever with most 40 size engines. For true tracking, smooth control response and predictability, nothing has ever topped the Sr. Falcon. Its light loading puts things in slow motion for beginners, but its semi-symmetrical airfoil and airfoil...
