If you''re wanting a 26 size engine, you''ll have a hard time finding a better engine and customer service than a Brillelli 26. You''ll find several lenghthy threads in the gas engine section of RCU about these guys and their engines. I have a 71" Sea Fury I''m putting a 36 on and the help I''ve received from Scott at Brillelli has been second to none. The egg shaped cowl on a P-47 would be great for hiding a gasser.
