Virtually any airplane will snap roll upon application of "up" elevator, if the elevator travel is in excess of what is required to force the wing in a stalling angle of attack. For normal, non-3d aerobatic flying, I try to adjust elevator travel until it is just sufficient to stall the wing. I take the model up high, apply full power, and full up elevator. If the model fails to complete a single loop before yawing and rolling away off track, the elevator travel is excessive. If it continues looping steadily, staying pretty much on track, the elevator travel is insufficient. I find that best overall results are obtained by fiddling with elevator travel until the model flies roughly one full loop before going crazy. This means that you can apply full "up" elevator close to the ground without having the model snap over on its back and bore into the ground. I repeat the process with the model inverted, applying full "down", to set the "down" elevator travel.

I have seen too many nice models crashed by application of too much elevator when recovering from a dive at low altitude.

So-called 3d flying normally requires much more elevator travel than normal aerobatics, so great care has to be exercised to avoid inadvertently applying too much elevator deflection. The best way to do this is to fling the model around at a safe altitude to determine what you can get away with, and how quickly you can recover.
