I’m going to overhaul an ICS M4, and want advice for the lowest stress combination for my specifications. So, a 22 TPA motor can easily pull an M120 on a 12:1 set. The stress on the gears, however, gets to be pretty impressive. A 16 TPA motor can easily pull an M120 on an 18:1, and here the gears are experiencing less stress due to greater mechanical advantage. I want to make a build that, unless there’s a grievous unseen error, functions reliably without subsequent tinkering. I already have a gun that requires that. So, for the lowest stress possible, and achieving 20+ RPS with an 11.1v battery, what would you recommend? Any motor, any ratio, and brand. I already have a parts list for the rest of the gun.
