RE: Which Engine
Hey Tanner,
Take a look at the Magnum 46XLS. It looks ike a sweet engine. Apparently the guy who started the magnum company used to work at OS so the engines are of the same calibre if not better. It also only costs $90 and the OS 46Fx costs $105(?) yet it still is a Ball bearing meaning you could put it on your next plane.
Just my 2 cents
Oh yeah, have you finished the lt-40? I'd love to c some picturez
