I'm building a Hangar 9 .60 size P47 and need some feedback on the engine for this plane. I was going to put a OS .61FX in it, but I needed it for another plane that is already built. I am torn between the Tower Hobbies .75, the Evolution .61NT, and the Evolution 1.00NX. I have even considered an OS .65LA, but I feel that it might be a little under powered. I am also on a budget, sotthe engine can't cost much more than $170.00. Thanks in advance for the input.
