I fly combat also. I make my own planes, as I can make them cheap. Airframe ready for eng-radiogear for $30 bucks. I make and sell them to the guys at our field for $45 bucks. Actualy If they give me their eng-radio gear I hand it back to them installed in the plane ready to fly. This has increased the combat pilots by alot. One person has used electric gear in one of them and it worked quite well. The planes come out at 2.5 lbs. Blue foam wings (I cut them) downspout fuse, and coroplast tailfeathers. We had two midairs last week so I got three more orders. Our planes must weigh under 3.5lbs, and be powered by a .25 or less...................What is the cost of a store bought combat in the .25 size?
