had my first flight today with the redone ucd. found out theres lots of vibration with the new saito 91. took off at half throttle, fly around at 1/4 for awhile , then decided to see how much verticla this puy took. pointed her up and away she went. flat spin back down to do the same thing, but as i pull up, i chop the throttle, and sit it out above the runway. start torqing a little, then back to putzing around the cool sky. gota love it. jeff
