if this is a new gun why are you doing this , why not take it back?

it's pretty clear it is a flawed product

Because I live in Croatia (Europe), and WGC shop is in Hong Kong.

check you tube dude I'm sure you will find something

I think it might be your motor! lol

But seriously, you may have a bent armature on your motor, it's not uncommon. You may just need a new motor

i say hook up your motor to a battery outside of your gun. then, watch it burn! >:D

Watch the battery go kaboom when the fire from the motor reaches it...
