RE: new cmp spitfire - man cmp is getting good
Pay close attention to stall speed. Practice way up high cause its a nasty surprise. It will warn you, its just real sutle. I used a saito 120 in mine. It wasnt over powered by any means but more like scale speed. Just enough spare power to get you out of a little trouble. A 150 would be perfect. I couldnt get a 180 to run in my CMP zero. I needed about a 24oz fuel tank and it was too high causing too much head pressure, couldnt get past half throttle. I swapped the 24oz tank with a 12oz tank and the 180 would run fine (reduced fuel head pressure). But run time wasnt very long. So, swapped out the 180 for a 120 and it worked fine. Just enough power for decent scale flying. Had to build a led box over the engine in the zero to get it to balance (about 2lbs of led). They are nice planes once trimmed out. Get too nose heavy and its a chore to get a good desent rate when landing. They come down kinda fast and hard. I had two spitfires and a zero.
