Hello everyone, I'm getting my saito 180 this week and I sould have my stearman in the next couple weeks following. Anyway are there any thoughts as to weather or not use 2 or 4 servo's in the wings??? I am hearing that the 180 might but at the far end of the envelope as far as power to airplane ratio goes and I wouldn't want to end up with another pile of smoldering fuel soaked balsa. So are any opinions on this subject? Also I am curious about this vibration phenomenon with the 180, soft mount or soes it really matter? I'm thinking 18-8 and low rpm 8000-8500. Low RPM = low noise oh yeah gotta like that putt putt sound
