See, just what I feared - engine requirements on kits are just like computer requirements on computer game packages - you can *run* on the minimum, but no garentees it will be enjoyable!

I am really hoping not to buy a new engine, in fact, the reason I bought the OS engine was that I was hoping to use it in my second plane. I'm currently on a Midwest Aero-Star, and I rarely ever go to full throttle, mostly cruising around at 1/3 to 1/2 throttle.

The reason I want the chipmunk is that I really like it's looks. Do you know of any chipmunk that might perform well with the .46fx? I did think of the airsail chipmunk (not quite the same variant), but the amount of information on it is lacking, couldn't find any reviews really.

Otherwise I may have to start settling for another good-looking sport-scale aerobatic plane.
