I haven't done much aerobatics other then some rolls and loops and a few high speed snap rolls. I was just basically flying around to break in the engine. Will get more time on the plane this coming weekend, and will tune the engine for better throttle response. Then will start throwing it around. As for expo, I never could get used to it. I too like things to start happening as soon as the stick is moved off center. I think I might need to move the CG back a little as it doesn't hold the 45 degree inverted line, and takes quite a bit of down elevator to hold it level inverted. It's balanced right now at the aft edge of the leading edge sheeting at the wing tip.
