Tonight I put my gun back together the first time. I popped my motor back in an put the plate on the bottom. (I have a G&G CM16 so it has an adjustable motor plate) After I put the motor back in I plugged my battery in to see if it would work. I pulled the trigger and this odd whiny noise, stupidly I pressed again and again until it just stopped. I don't think anything in the gearbox was damaged besides the wiring, which is what my dad thinks. Any ideas to what the problem would be? Please help, I'm getting extremely worried as it was a bit pricy with a few external upgrades.
