This is my first attempt of making an inexpensive, fast-builded small plane.
The wing is made of two 60cm*10cm*0.5cm (23in*4in*1/4in) balsa sheets and powered by a 12 engine.
It flew, but had a sewere pitch stability in high speed. I later fixed this by building a profile in thin (0.8mm/1/32in) balsa sheets over the flat wing so it got a Clark Y profile.
Now it is a funny, inexpensive little plane with flight characteristic of a F16: high wingloading and tolarerates high AoA.

The Cub in the bushes just before the field. Something just reached out and pulled it into the bushes!! (The gravity maybe!)
The Cub piggybacking a small foamdelta. The delta was mounted on a servo-operated stand which was attached to the Cub with rubberbands. The servo locked the delta until flipping the 5channel switch on my radio.
My buddy then guided the delta back and lost hisfight against the gravity.
It worked very well.
