Just to add my experience with the 9918 (9920 now). When I used it in my 1/8 buggy going off of jumps, one normal landing caused my buggy to stop moving. After asking around, I removed the shrink wrap to find that one of the components on the bottom of the circuit board had cracked, even though there had been some padding below it (one layer of velcro on the chassis only). Later, Mike had the controller and was looking at it, and saw what he thought was a thin fracture in the circuit board. At that point he pretty much just sent it to BK.

So, if what has already been suggested doesn't work, it may be worth it to take the shrink off.
