Yeah, that will help with the snap but then doing a loop is out of the question. I can keep it from snapping being really easy on the elevator and catching it with the aleirons but I still need about 100 feet going in to the loop and end up damn near dragging the ground... not really a good feeling. I would like to pull a tight loop and end up and the same elevation as I started.
A snap is nothing more than a stall. A stall happens when the load the wing is carrying at the speed the airplane is flying needs lift that requires the wing to pitch to an AOA that's beyond the stall. Speed affects it, load affects it, and your ability to hold the correct amount of elevator affects it.
Adjust the elevator rigging and it'll be easier for you to fly as tight a loop as the airplane can fly. Then you'll have a clue if redesigning the airplane would be sensible or worthwhile.
