This is the first Flying ving my buddy had. It was made of something similar to EPP-foam, so it was rather crash resistant.
First flying attempt was done with a electric motor taken from a hyperfly. (witch he wrecked earlier). He managed 30 sec in the air. It would not climb at all. The following attempts destroyed the hyper-electric motor. Too mutch boinking on the shaft, I think!
After that he added a lot of noise and improved the power-to-weight ratio. It transformed into a good flyer
At the same time I builded a wing of the same material with a larger span, making it less areobatic and with a better glide angle.
The elevons where made of cardboard. taped to the wing with duct-tape.
Notice the yellow silicon tube attached to one of those cox-mufflers (muffler??!). This setup killed some of the noice and power :( and reduced the amount of gugge hitting the wing.

Of course we flew at the same time. And did dogfighted a bit. We tried to hit eachother, but it was indeed very difficult!
One time we managed a midair, without actually trying. Mine wing survived and my buddy lost his engine. We spend some hours kicking grass before we found it.
This is my buddy's flying brick. It's made of a 50 cm (20 in) section of wing from a low-wing-airplane called Atlas. Power is a enya 25. Three standard servos and a standard battery pack made it heavy!!!
It is not even remotely stable and he had to re-learn how to fly, becouse it does not behave like a plane at all!
It was not possible to land it, becouse it entered a spin if you tried to reduce the trottle to mutch. He managed to land it once, with a power-off glide of 1:1.
The picture is taken after one of his landing-attempts.
