I unintentionally try to teach the plane to float without enough speed. The good thing about this plane is that it crashed a few times and nothing happened - this is made of Coka-Cola type plastic, just 3 times thicker. The wet mud helps too.
The fact that the landing gear is a little soft helps - it bends on almost all landings (even good ones) and absorbs a lot of the energy. There was a rubber sign on the underside suggesting that the front wheel hit it! I am sure a balsa plane would have needed major repairs. This thing will retire when I have a 10-20 flights after soloing, so I am glad it survived the learning process.

However, for aerobatics it seems most airplanes are very durable: I built the wing without a wing joiner (just a strip of fiberglass cloth). The thing survives VERY tight loops in spite of the heavy fuselage.
