Ed, thanks for the reply. Well the weather gods smiled on us today. Headed out late this afternoon for a good 4 hrs. of flying and general BS. Watched two guys put six planes in, one right after another. Comical. Then it happened, the wind went flat, dead calm. All you could here is me gigling putting the wing on my UCD. I'm likeing the 15/4 prop. Slows down more than the 15/6, but its comfortable. It will torque the plane in a hover and still has authority on pullout. Didn't have the tach with me (again) so i don't have any data to pass along, but it had a noticible increase in RPMs over the 16/4 and spool up was much quicker. Still impressed with the Cline regulator, talk about smooth performance and low idle. Once I get a tach on it I'm going to run the high end needle out just to see what happens. I've read that some engines are at about 2 3/4 turns out. I'm still at 1 1/2 turns. This plane is a sweathart, its so light, I don't think it leaves tracks in the grass when it lands. Talk about floating in. Still can't figure out the too doo about knocking the gear off. I guess thats just what it is, their knocking them off. With a little luck, tomorrow will be flying weather as well. Joe
