RE: What engine on a Power Mac 310?
Ralph,
I would appreciate you letting me know how your Moth does on the Homie. When I get mine, I'll check to see if the Ryobi will fit or if your Homie does well, I may put it on there and save the Mac for a warbird. I had converted the Ryobi to put on a Dynaflite SE5a that I am building. Although the Ryobi is narrow it is also Loooooong. May be too long for the Moth. I already know that I will have to move the firewall back on the SE5 to make it fit. But since I haven't built the fuse yet that is no problem. Also it will move the weight back a little. Either way, both bipes should have plenty enough wing area for a Ryobi.
