Help! CTW Problem!

Here is what has happened

I put in Celcuis 11.1 Lipo, gun blew 2 fuses right off that bat

Put in 9.6 and the gun motor is attempting to turn it just chugs alittle but doesnt move ( gun is open so i can see if the gears are moving at all, it just attempts to move )

any idea's? The fuse is good, just motor isnt turning, this motor has been modded by hotspot. I just dont know much about these guns

thanks for any help

Can you turn the gears in the gearbox by hand?

They do Now, after I turned them earlier using the motor

Hey try another battery also I would check the wires in the gun to the motor or from the battery to MOSFET sounds like you have a short somewhere on the gun. If you can turn the gearbox by hand a full revolution there wouldn't be any problems there so either wires or the motor which you said works I would also try pulling the grip off with the battery in pull the trigger with the gun open if the motor turns and gearbox turns no problem you could have a cylinder problem
