I am getting the Great Planes Patty Wagstaff 300s. It has a wing span of 78" and final wieght of 14 - 16 lb. The specs call for 41-65cc gas engine. The guy at my LHS says the 58 would be to much engine because it is more powerful that other brands. I thought the 58 would be best but he says it would be to much engine. I know people who have Zenoah g62 on it and he says the MVVS 45 has more power. Is this possible.
