widowmaker.. there are some good threads on the ucd60. It is a great plane. I fly with a ys1.10fz and it is well overpowered. cg at 5.5. Make sure you put some thinned epoxy around the firewall with that big of engine in there. I don't care what anyone says on the threads either... the apc 16x4W prop is an awesome prop for that plane and engine combo.. fast spool up and great response. I put a 16x6 and the thing won't sit still or land w/o killing the engine. The 16x4W will act as a break when let off... gives you full throttle control.. it is awesome.. hovers between 1/4 throttle and 1/2.. I had to put some expo on the low end throttle curve to give some resolution and the 16x4w helps with that too.

On the twist. Has anyone got it to harrier yet? like a good 45 degree straight down the runway harrier? I just bought one of these. Was talking to a guy that was able to get it to do a climbing inverted flatspin (tornado)... ROCK!!!
