Scratch Building RC Planes

I like to make FPV RC planes from scratch. My first build was based on a chuck glider 'Air Rider'. I basically took a kids toy glider and added control surfaces and a motor and prop. An ELRS receiver was paired with a CRSF->PWM module for radio control. It flew terribly. The first two hand launches failed miserably, I think I was not launching into the wind amongst other errors. By the third launch it was haphazardly taped back together in the field, but I got a very short flight (maybe 10 seconds) before it came apart and crashed. Some joy was had though and I was not ready to give up.

Plane Two : An Armin Wing Build.

So the toy glider remains were stripped of parts and and the foam still sits in a carrier bag in the shed. The next plane was going to be different. I had seen the awesome Armin wing builds of Ed from the YouTube channel Experimental Airlines and was inspired. Ed's tutorials are great. The Armin wing is a wing made from 6mm foamboard, the boards are sheet of styrofoam covered both sides with thin cardboard. The wing is formed by folding a board across a spar made from thin strips of board creating an air foil profile. The boards are covered with packing tape on one side to offer some water resistance and also to stop the cardboard ripping along the fold at the lead edge of the wing.
