A guy at our field used one to learn how to t-roll on. He had a Saito 1.80 though. One thing he did that I really liked was modify the elevator to have counter-balances. The extra surface gave him better control. Well it worked, he is now doing 3-d with the H9 1/3 Cap. On my 1/4 Katana I have the Hitec hs5625 digitals on the ailerons and the hs5645 on the elevator and rudder. They work great. Way more than enough to fly a plane of that size.
