When i was flying mine i had to build a new rudder. Even then it didnt knife edge real well. I couldnt get enough throw out of the elevator and couldnt get the cg back far enough so i mounted the elevator servo in the tail along with the batt. After that it flew pretty good. Waterfalls were pretty good but still had a hard time holding a hover. It would hold knife acrossed the field but it was on the prop mostly. If the motor was not tuned perfect it would fall out of KE.

I striped the fuse and modified it. Still have to cover and fly it. That will have to wait till summer time. If you want to see it click on website button on the bottom.
