Make sure you use good quality pushrods to the tail feathers, as they are long and need support. Try to keep all of the weight up front, if not they can get tailheavy fast. It really needs flaps to land, it is a challenge to land without them. They fly GREAT. I have flown a couple of them, and each one is a ball to fly. BOth had G-62's, you do not any more motor than that.
