H9 Cap 232 (smaller one, not the big one) snapping
Almost all of today's scale aerobatic models are elevator sensitive because they are designed that way. Why, because 3D flight requires a very effective rudder and elevator. Usually, people don't get into too much trouble with an over sensitive rudder, but the elevator is another story.
When I'm flying a new aerobatic plane I set up the elevator at the lowest recommended elevator throw and I set up another rate that's 1/2-3/4 of that throw and I always dial in some expo. I also use the front of the CG range. This will greatly desensitize the elevator which is very important to me in the beginning. As I become more familiar with the plane I begin to move back the CG and then dial in more throw if I feel it's necessary. If you want 3D ability, I recommend you set up dual or triple rates so you can have wild throws while stalled and sane throws for everything else.
BTW, I've owned a couple Caps, an Edge 540, a Staudacher and a One Design. All of these planes had sensitive elevators.....nothing like the typical sport planes I was use to.
