Today Richard Dick and I helped (Well, we offered what assistance we could) to Bob Galler. He maidened his MG 2 after an extensive rebuild of the wing. Bob's only flight of the morning was the result of using a 3S LiPo pack. Bob worried about that power but the big model lifted off and was going well at 3/4 throttle.
After a graceful landing, Bob admitted that he would really use a 4S pack in competition.
