Hey guys (skip to end if you really don't want to read it all), I have had my CA MOE for around 7 months now and while back I shot around 1000 bb's with around a 1 minute stop between each mag change/reload. After shooting all that, I tried to shoot again and it made a whirring sound, I tightened the motor screw, and it worked. That has happened (the sound) multiple times after and I fixed it by fiddling with the motor screw. Then one day a month ago, I tried fixing it after hearing the sound. and it didn't work. I cannot access the motor due to a stripped hex (Magpul uses hex for the stock screws). So I was looking around and saw that I should use a discharger (I knew that before, but looked past it). Would this be it? Do I need to get a discharger and a new battery or is it the motor? In short...My motor is making a whirring sound, I cant access it due to a stripped screw, should I just go to a store? But I think I might need a discharger cause I never used one, would the un-discharged battery be the problem maybe? Please help. Thanks for all the help in advance.
