Your right on about the bearings locking in the blade system. It just seems that when she's up in the air and all is perfect in the flight, the top just shoots off in its owne dirrection. I'm thinking of going to helihobby and moding this baby up. I know all is well with the blade balance and the blades are set pretty well. And the bearings lock the system down pretty well.[&o] Though I have to admit that my landins are a little rough and I do mean a little, I always go back and recheck before relaunching the heli.
