slower gears.

The motor will work with those gears but it's a high power consumption motor on a set of gears that requires more torque to efficiently turn them. That setup is likely going to draw 26-30 amps on a constant if pulling 10:1s probably 24-26 on 12:1s. Burst draw is probably closer to 100 amps, so the likelihood you kill battery packs will be higher. A better motor to use in a low ratio gear set would be a shs torque or zci torque motor. A zci will draw closer to 15-16 amps and you can run it on a stick lipo if you are space restricted... though I like bigger batteries for larger margin of safety. What you give up in top end speed in full auto you retain in your semi cycle speed. It will complete the first cycle much faster and much more efficiently.
