i had a WM CAP232 with an OS FS70. the plane itself seems too heavy for 3d aerobatics. on the FS70, the plane would hover but will not pull out of it. i had a buddy though who has a 40 size aeroworks edge 540 with a 91fx slapped on to it. that plane could basically do everything. perhaps the CAP 232 might be able to do the same things with a 91fx.
