For what it's worth, I just got in from flying my T-craft for the first time with the used Supertigre 2500. All I can say is "I love it!". I've got some smaller ST's and I've had great luck with them. This one was used and has an OS carb on it and it flew great. Take-off was easy at half-throttle and the uplines were fine for me. I don't care to get satellite clearance when I fly so I'm not sure how high it COULD go. The Hangar 9 T-craft has a LOT of rudder authority! I've got a lot of throw in my rudder and on the first flight, it made itself known. I put about 40% expo into it and it flies just great now with AWESOME hammer-heads.

I didn't need to use the throttle much and it just sipped on the 5% Nitro fuel. I got the plane and the engine used but it is quickly becoming one of my "must-fly" planes.
I think I've just found myself a new favorite airplane!
