Although I haven't had a Super Sportster 60 I have extensive R/C experience. The extra servo will give a better aileron response, although since it's your second plane I assume that your flying skills may still be toward the learning curve. In this case, the response speed may not be essential for you. Response speed comes into play when you want to whip the plane around for advanced aerobatics. I would not recommend this for learning on your first low wing. As far as shortening the ailerons, I would build the Sportster according to the instructions. Hope this helps. Good luck and happy flying!
