This is the Phoenix Stinson Reliant with a Saito FG19R3 gasoline radial engine and Keleo exhaust ring. The engine has enough power to fly the plane in it's scale form which is all it really needs. Its not a very powerful engine, but it does sound cool. Not as cool as the larger Saito radials like the FG60R3 or the FG90R3 but cool enough.
The engine doesn't fit in the cowl very well on this plane. I had to cut holes for the valve covers and grind out areas in back to let air out of the cowl. I think the engine is getting a little too hot so I'm going to buy a custom canopy or order a Phoenix Waco cowl when they are in stock and try to develop some baffling inside to keep the engine cooler.
