Was landing the air and as it landed the one proper hit a shoe that was holding the landing pad down. Contact stuttered the motor.

Shoe was flexible and going slow enough that the prop has no damage. Can something like this hurt the motor or are they pretty resilient?

I've done worse hits than that with no problem.  Of course, test this by simply raising your quad about 6 feet off the ground and let it hover for awhile.  If there's a problem, it'll show up there.
