Hello everyone. I have always wanted to build a radial engine, so about 3 weeks ago I finally started one.
I thought I would post some pics, and get some input. The project started out as a 4 stroke, but midway through I decided to go 2 stroke.
The bore and stroke are 1" x 1.125" and the displacement is 130cc.
I started to duplicate the 5 bears hodgson radial. The bore and stroke dimensions are the same and that is all. I have completely designed all parts from scratch, including the supercharger.So far all parts are machined from 6061 AL except the jugs they are 12L14, and the crank is 4140 PH.
I hope this is durable and reliable enough to power an rc aircraft, but I'm not sure what to expect. Anyone have any experiance in this area?
Thanks for your input. I will keep posting progress.
