Well I finally maidened my ultimate today. I only ran 2 packs (TP 2100's) through it though. A couple clicks and the plane flew great. I flew with a 10x5e apc prop and it seemed to have plenty of power. It slowed down pretty good too. Run times were roughly 10-12 min. I didn't throw nothing hard at it. I did notice (with my set-up) on tight loops it liked to snap out at the top. The knife edge is pretty good too. I flew mainly at 1/2 throttle (full throttle a couple of times) and the ESC and battery were pretty warm, but I had no cut outs. I need to get a watt meter so I can tell how much power I'm pulling. I think I need larger arms for my aileron servos, as my roll rate was kind of slow, but still not bad, compared to my rudder and elevator. On high rates I have as much as I can get on all the tail feathers, and it seems to flip the plane around pretty good. On the second landing I came down kind of hard, but no damage other than the landing gear was bent some. I think I'm gonna put some checkers on the bottom, as this plane can get small quick if you don't keep it close. This is a great little bipe. [8D]
