RE: Aeroworks Extra 300 35cc QB Question
Yes, I was worried about the balance problems that I read about with the 300. I guess I will go with the 260. For an engine, I will use a DA 50 since I am at 5000' altitude. I have seen someone here fly a H9 260 with a DA 50, and I liked the way it performed.
About moving the engine forward to help the balance problem, according to my calculations using a 3 lb. engine on a 14 lb. aircraft, moving the engine 1/4" forward will move the CG approximately 1/16". That is not much. A 1.5 oz. weight on the engine box will accomplish the same thing.
