RE: FG MT tips I found helpful!
The kill switch sticking problem is easy to fix. Put a small machine screw into the plastic button of the switch. When the button is stuck 'in' you can pull it back out easily with the screw head.
Drill a hole in the plastic button of the switch slightly smaller than an small machine screw. Screw the machine screw in enough to hold but not too deep and you're done.
