If you want to fly RC on the cheap,

If you can pick up an old crashed plane with it's engine and radio intact,
SPAD air planes can be built for less than $20..

The SPAD3D plans are some of the best I've seen.



Here's the last one I made..



The air-foils are coroplas, the Fuse is a 3/4" al rail (plywood endcap)
and the engine mount is plastic cutting board (snagged from kitchen).

No smelly glue and very break resistant during hard landings..

Takes a few hours to build one. And they are a lot of fun to fly..


I'm making a low speed pass under a banner, before dumping a golf ball
out of a cup taped on top of my plane.. It was a contest.

Cheers,
