Hey Near Hit, I am using an ibec with my Evo 10 cc and I am also having problems. I flew mine today and could only get one short flight on a 2000 mah battery. The enigine quit suddenly after about a seven minute flight and I could not even get the engine started for a second flight. My voltage checker indicated the battery was weak after about a seven minute flight. I am going to put a second battery and switch in mine and get rid of the ibec and see if that fixes the problem.
