If you look at my profile pic you'll see that I have a few plane builds under my belt, that is only some of my builds from the past 2 years... There are just as many built up balsa / nitro planes at the other end of the shop.
I've done durablility testing on the tape technique at Flitefest (by accident) with my FT Flyer. As I was running out of planes to fly do to mechanical failures, I had to put my turnigy 2826-2200kv speed plane motor on my beloved FT Flyer with a 4s and a 6x4 prop for something to fly. While doing rolls at a rate of 4-5 rolls per second, my wings (yes, front and rear wings bent slightly causing loss of control. Since I was in the middle of a high speed low (10 ft) pass while rolling, there was no time to recover... 65mph to zero in 1 second as it piled into the ground in pieces... upon further investgation I found that the glue joints all popped on impact releasing the energy of the crash. I used a monokote iron set to low to gently flatten out the bends then press a steel ruler on it to cool and flatten my parts. I glued it all back together and it is stronger than it was previously. It flies great again!
