RE: Zenoah 62 for 3D?
I know the Zenoah 62's are heavy but I would think it would to the job, as long as you could get the plane to balance right without adding weight. However the 62 might be just enough power, My motto is too much power is better then not enough. If it was me I would buy a DA 85 or the biggest engine I could fit on the front of it.
