Hello. I'm fairly new to this site, so please excuse me if I'm starting a thread in the wrong place. I couldn't find a previous thread about my question.
I have Lanier Yak-54 ARF in the box, 87" span, and 16-18 pounds flying weight. The plan calls for a 50 to 80 cc. engine, and the manual shows a DA-50 installed. I know a guy who has a Zenoah G-62 in his, but he is not heavily into 3D flying, so he's OK with the extra weight of the G-62. But I was hoping to go with a lighter engine, because I'm learning some 3D stuff. I was thinking of trying the new DA-85, but some guys at the club think this would be too much engine for the Yak. So my question is, how would you guys compare the potential performances of a G-62 vs. the DA-50 in an airplane of this size and weight? Would the DA-50 provide enough power? Thanks.
