guys thanks fo your responses i did use a soldering iron per the instructions when i cut off the covering for the stab and i was barely in the throttle at all i taped all the hinges before the first flight and as far as speed im running a os .70 fs with a 14X4 so its not fast to begin with but who knows i think im going to build be a stab and then send the other one to great planes and have them send me a new one thanks guys oh if you look in some of the older forums on the u-can-do 46 there was alot of talk about the wings buckling i figure from wing loading
