I´m building my first big scale plane (GP 1/3 Pitts) and trying to fine a good 50 cc Gas engine.
Can someone tell me why is there such a difference in weight between engines?? The Fuji BT-50SB is about 74 oz(heavy end) and the DA-50 is 47 oz(light end). Same happen with other brands. There is a difference of 57% when compared to the DA 50 weight......
Please comment.....Thanks
