So im trying to fix my friends gun. The original problem was that the stock 8.4v (fully charged) wasnt powerful enough to turn the motor. I tried adjusing the height and that did nothing.
Today I took his gun home with me and just for kicks, plugged in my LiPo. The gun actually fired. I then tried my 9.6v and it fired. I also opened up the GB and everything was fine. The only weird thing is, is that when i use the 9.6v with it, after every shot i hear something vibrating inside the GB. It didnt do this with the LiPo.
Is this just a case of a faulty battery? I dont understand how a non-upgraded gun wont shoot with a stock battery.
