is my motor blown - from a noob

[exploreh2o]

Good evening everyone, as a noob to the group, I am posting this similar question to a couple of groups via FB. I welcome direction to various forums to find the correct answer. Situation, have a new P2V+, today was day two of test flights. Needless to say, I did have a crash in a small brush. The concern is now, my rear left motor seems to be miss aligned. It shudders. The other 3 motors are fine, but the one motor, doesn't have the speed and has a visual skip. I have taken the props off, but I haven't dismantelled the whole unit yet. Trying to find out if there is a simple way to confirm if the motor is shot or if there is a way to reset it. Thank you.

Didn't have to take the motor out, just take the top shield off. So if anyone needs clarification, there is a total of 12 hex screws and 4 philip screws that need to be removed so to be able to take off the cover / shield. After several on / offs, and much compressed air, I am glad to say I have the sweet sound of a smooth motor again.
