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. |

Here is what you do. Take that G-62 Tie it to a rope, and now you have your new boat ancher. Zenoah needs to do something because they are being passed up by all of the other manufatures making new engines. If you want an engine that will be with you for along time never by a weed wacker motor, IE Zenoah, Fuji, or anything like that. You will have more Problems then you have time for. The lanier is a heavy plane. There are alot of other planes the same size that way less. But you allready have it so make the best of it. I am a big DA fan. But I think a better engine would be a 3w55i or if you can find one a 3W75ius. They will give you the extra power you need to HUCK that tuna boat around. Spend the little bit of extra money for a good engine and you will not regret it.
