Thanks to everyone for all the help. I received a lot of useful information. I've checked everything mentioned and made some corrections, so as soon as the weather gets better i'll try her out again. I've been flying this cub for over a year. It's always flown great with no problems until one windy day when it made contact with a tree. Until then i could toss it, throw it hard or take off from a runway. It has never stalled or crashed in at least 50 or 60 times out.. This cub flies great and is very forgiving. It always takes off without the use of the elevator or rudder, until is is far up in the air. I was going to try to launch it without power because the last three times it crashed and of course broke the prop. I even changed the motor because i thought the brushed motor was just wore out and didn't have the power to launch it.. When i bought this cub i did notice that the motor had a thrust angle of down and to the right, but the problem was that was over a year ago. I'm thinking this angle has changed from a few hard landings. If i took this angle out would it still launch o.k. When it is flying, i noticed it always went to the right.
