How to build things that fly with these model airplane plans. Ever since I was young, much younger than I am today, I have been interested in unusual flying objects.
Trying to decide what to include on this page was quite easy. I did not want to compete with the hundreds of free model aircraft plan sites that I have come across in my research. Instead I wanted something unusual, interesting, different.
They could be free flight, RC, control line, rubber powered, Jetex or gliders. You could build them as they are, or use the existing design as an inspiration for one of your own.
For example, take a free flight model airplane design and convert it to RC.
A free flight canard biplane model airplane plan designed and built by R Wrisely. 25 inch wingspan, 200 square inches wing area, powered by a Cox 020 Pee Wee.
There are a few modifications I would make to this design.
First, use the good old Clark Y airfoil section for the wings. Maybe scale it up for electric radio control. Change the shape to something more round.
If two wings is good, three wings must be even better, yes? Just one of the many model airplanes designed by Ray Malmstrom.
To quote the article from Aeromodeller Annual:
This design from the Tel Aviv Experimental Center for Areomodelling and Low Speed Aerodynamics, inspired by ING F. Piatelli.
Looks like playing with model airplanes was a serious business back then.
The original built from hardwood and hardwood veneer. I’m sure it can be built with balsa wood.
An unusual feature is the anti lift tail plane, an inverted aerofoil section. Apparently it was something favoured by the Italians, used in many of their flying boat designs.
No tow hook position is shown, but according to the article, it should be about 3 inches back from the nose of the pod.
If I was to make one, as an experimental prototype, there are a few things I would change. First, change the construction of the wings with a few more ribs and a more substantial leading edge.
Also, vertical grain webbing between the spars for the first third of the wingspan. For the pod and boom, I would more than likely use soft balsa sheet instead of the polygonal pod as shown.
It would be an experimental prototype, after all, and I would hate to see all my hard work come crashing into the ground on the maiden flight.
Dimensions in inches:
Span 39 ½
Length 27 ¾
Main plane Chord 5 1/8
Tail Plane Span 12
Tail plane Chord 4

Another vintage toy airplane plan from the 1948 edition of Aeromodeller Annual. This is the Dutch tailless glider by W. Luxemburg.
It is only a sketch with not much by way of construction detail. Dihedral appears to be 1 3/8 inches at the wingtips, with a 7/16 inch washout.
It also features an unusual method of fixing the rudder, which I imagine would make it detachable, why I'm not sure.
I could use it as inspiration for my own design one day.

Featured in the 1952 Aeromodeller Annual, it is a free flight design which I think can easily be adapted to Radio Control.
With a wingspan of 82 1/2 inches the original was powered by a 5 cc Bonnier diesel (similar to a Micron) with a four blade propeller.
Purely out of curiosity, I searched for the term Bonnier diesel, and found Adrian's Model Aero Engines.

This is a free flight balsa model airplane plan for an autogiro powered by an 049 engine.
Simply for the joy of building something that flies. If I was to make one today, I would use a brushless electric motor with radio control.
Apparently an 049 engine has the power output of 80-100 watts, so that is what I would use.

Designed by Paul DelGatto, from the Handbook of Model Planes, Cars and Boats 1965.
Powered by the popular Cox 049 or 020 engine.
I made this air powered hydroplane model many years ago.
Very simple construction using a half a sheet of 12mm balsa, which means you could make two.
It was powered by my favourite Cox 049 Baby Bee.
I have made a 3D model using Sketchup.

It should have been a tethered model, I suppose, but at the time I had no idea about this sort of thing. It was an experiment. I ran it on the Olympic size swimming pool at school. I managed to convince one of my co-conspirators to catch it at the other end.
Quite a feat of bravery if you consider this small object making the noise of a thousand angry bees coming at you at a million miles an hour. Not to mention an unguarded 6x4 propeller spinning at about 10 000RPM quite able to do some serious damage. I still have the scars to prove it.
One more thing, seeing that you have read this far. One of the teachers did mention the (very) thin but easily dissipated film of oil left on the surface of the pool. Ah, the joys of growing up in the 70's.
