am in process of having a 90" P47 finished up. Fiberglass fuse, foam core/sheeted wing. Builder is conserned about weight at 25#, including engine, etc. a BME 50 is rated at 4.8hp, while a G62 is 4.75Hp and heavier. Do you think the BME50 will be enough for scale flyinf at 100' above sea level?. Thanks
