Hey guy,

Need some help. I order a brand new E90 gearbox from airsoft gi.
Anyway using a normal 9.6v 1100 batteries and hook it up with the gearbox. I notice the wires and the batteries get super hot after trying to shoot it, and also the piston is stuck half way.


My guessing is the batt but no clue....


Thanks,
