Well see I am not really doing this mainly for 3D. A guy I know had a GT-80 on a Sukhoi and it hover well and pulled out great. The book really suggest a GT-80 or ZDZ 80. The only difference there might be is that I may not have as quick response for the GT-80. But I can hover a plane really well and can handle it. My parents on the other hand really doesnt want to buy another motor. They said later on in the year I can if this motor doesnt appear to work well. Then I can put the GT-80 on my Giant Stinger I have. We will wait and see. I may like it.
