Hello ? We only have 1 short test flt on our Razzle so far and have not tried any real tight loops with the flaps mixed in yet so not sure , but it sounds like you have to much ele in it.
On most of our FF planes I dial in as much ele as it will take for a tight as possible loop , then start to dial in the flapps about 10 % at a time untill it tighten's up even more. Normally the flapps will not make it snapp out - it will just get real musshy and not pull thru the loop at all (to much drag) ! How much flapp do you have in it now ? Let us know how you make out.
