Yeah, for me it helped alot to use the aluminum stickers to hold the flaps in place. I added a 1/2" screw to the nose of mine and it flies perfect. At 1/2 throttle it levels out perfectly and full throttle climbs great without the porpoising. The only thing is I can't seem to get it to turn any quicker. I've turned the motors in different configurations but it doesn't seem to make any difference in the turning radius. If I could get it to turn sharper it would be even more fun. One more thing. Even with different trim setting on the plane and the controler, it always turns right sharper than left. Who knows.
