I’ve recently had an issue with my ACR’s motor and wanted to find a replacement that was close to OEM with some added reliability.
The issue was the motor threw a bunch of copper-looking dust into the grip which worked its way up into the gearbox. Everything still works after a full gearbox clean, but I want some protection against it happening again in two-months time.
It’s the stock nylon box with an upgraded O-Ring and a 1.18 Ausgel spring, feeding off a BosiLiPo ACR specific battery. Most of the offerings I found would make it a speedy-boi and make the gearbox scream.
