I finished up my SE the other day and have been waiting for a nice day with no wind to go. Well today was the day. I have a OS 70 FS on it with a 12x4 APC prop on it. I could not have asked for a better day. It flew like a dream. Engine was flawless (only about 3 tanks through it). Only trim needed was a little up elevator. The vertical was awsome, although I would like a little more. What prop should I try. Do I go longer on prop like to a 13x? or do I up the pith to a 12x6. What would be the better for more torque? Anyway I will post pictures in the morning of my little SE.
