Thanks for the response to my question. There is a member at my club that has a DA50 in the Aeroworks 35cc Extra 300 which is the same size and weight as the 260. Other than for takeoff, he doesn't go to full throttle very often. He does not fly 3D maneuvers, just routine aerobatics. It is an impressive plane with that engine. Aeroworks says the 35cc 260 or 300 uses a 35cc to 45cc engine so the DLE55 isn't too far above that. I don't think it will be too much for the plane to handle. I don't want to spend the money that a DA commands. From what I've read I'll be very happy with the performance of the DLE55 at much less cost. By the way, Aeroworks has the 260 on sale for $150.00 less than regular price. I think it's a very good buy.
