not too unusual i dont guess but with an eaglet 50 on its maiden flight it needed a lot of down and right trim so of course it immediatly climbed and turned left in to a tree hit about 25 ft up and fell landing on all three wheels with no damage done. then about 100 flights later i was playing tag with a heli well he thought it would be cool to go in to a hover in front of me by the time i saw him it was all i could do to roll knife edge and pull full up but still put a wing tip through the main rotor blade i flew around and landed with a crooked wing and missing tip but you know he beat me to the ground
