had a crash with my hb cp2 this morning, now one of the servos is just humming like mad, and doesn't seem to move in it's proper range. Is there any way to test it to see if it's broken or what's going on? is this a known problem?

Thanks

You may have broken some of the gears inside, they are tiny. Since this is a possibility, be careful, you could burn out your 4-1 if the servo is jammed. You can check the servo on a different channel, if it doesn't work on that channel while another servo does, then it is your servo. They sell a gear kit for around $4.
