Hello everyone! I'm new to the forum. Have owned several J-3s in previous years and recently owned (and just sold) a Zenith CH-701. I now want to build a J-3 in the experimental category but really want a "helicopter with wings" so here's my question: What would be the best engine (experimental) weight to HP ratio to install in a J-3 frame for maximum takeoff performance. I've emailed Don Swords and waiting an answer but thought with the tremendous talent in this group, there may be other options. Thank in advance. Jim S
