When you apply a lot of elevator, this thing snaps, just like "Caps" do. if you let the airspeed bleed off it will stall straight forward, but i notice pretty much every time i want to pull hard to the vertical, or pull hard out of a dive it'll drop a wing really quick.
This is not unique to Caps, as many people know. Any aerobatic plane will snap out with too much control throw.
The reason it happens more easily on a Cap or a Giles is the tail is so high, it's out in clear air and can push the tail farther and increase the angle of attack more than a plane with the elevators in-line with the wing like a Yak.
You just have to learn how to fly this kind of plane, set it up with less throw. Different layouts require different techniques to get the most out of them.
Everything on an airplane is a compromise. More strength requires more weight, better performance requires less weight.
And a more powerfule empennage means it can do things other planes can't do but it reqires a more gentle touch. You can't take a plane with a powerful tail like a Cap and just hammer it around like a trainer. They don't work that way.
