"great gearbox, mine came complete. thought it wouldnt come with a small tamiya connector but it did and with a fuse on it too. shimming needs a lot of work but since its not installed yet, now is the perfect chance to do it. 4 outta 5 just coz the shimming is off. be aware guys, bad shimming causes broken gears. over all amazing gearbox, highly recommend. buy a shim set with this.

"This gearbox is great, it drops right into the A&K SR-25 carbine with no modification and no resistance. It does not come with any kind of battery connector (as pictured) but if you want to change to deans, that's not a bad thing. I just used the connector from the old gearbox by cutting the wire with some to spare, and soldering it to the wire off of the new gearbox. It was an easy fix. Definitely recommend this to anyone who needs a new gearbox for the A&K SR-25 carbine. Just takes a little soldering.

"Decent internals but no battery plug comes with it and the wires for a plug are motor connectors
