I used the OS .60 on mine and it was about perfect for the plane. I just flew it, I didn't use it as A tow or anything. A G-62 could be A lot of fun.
Mine didn't have any aileron control problems and I cut the ailerons down by A third for flaps. It did need some rudder input on turns though just to give it some help and I had A lot of throw on the ailerons.
One of the planes I had the most fun with. Got to fly another one two weeks ago and loved it, could have had some more wind though, that's when they start getting with the program.
