The Giles is fine as long as you keep the speed up when landing, BUT it is one of the worst models around (especially when it's on the small size like a 40 size) for snapping when you don't want it to.

It will slow speed snap when you apply too much elevator and will even snap when on a fast downline if you use too much elevator to pull out of the dive. In fact, I would recommend you spend the first few flights taking extreme care to adjust the elevator throws so that you don't accidentally apply the amount that will induce a snap. Fly high and try a tight loop, and reset the throws so that maximum elevator doesn't make it snap out at the top or bottom of the loop.

Good luck!
