RE: 1/2A Size Boat Club
Especially when these engines are used to pulling around a 20 ounce plane.
That's a great effort you put into the riggers to get the engine to work.
I would like to see more pics of the machined exhaust.
Is the prop soldered onto the propshaft or are you using threads? It's hard comming up with a streamlined strut without making custom with these. Is that the Dumas metal prop?
I see your using a five fin texaco head too. How about the flywheel?
