These are the motors..... http://banebots.com/pc/MOTOR-BRUSH/M7-RS775-18
They are actually Mabuchi RS775WC-8514. The part number is on them under the BaneBots sticker.
I had lots of questions about these so I had to test them. I was looking for more torque and the 1175 mn-m rating on these was astounding. The stock PW motors are under 400 mn-m. They are advertised at 273 watts at peak efficiency. (scooter motors are 250 watts)
I was concerned about the gearboxes and the wires. These draw lots of amps!
The first thing that caught my eye was the thickness of the torgue sleeve....one big chunk of steel!
I put these in my 18 volt 4x4 jeep for testing. Since they are 18 volt motors I installed them without heatsinks, just like they came out of the box.
The motors bolted right to the #7 gearboxes without issue. The pinion , however, required some "tinkering". The shaft on this motor is not long enough to install the pinion gear "backwards" as required for the #7 GB. I installed it frontwards(set screw side facing the motor) and made a shim out of some lexan scraps to line up the gear. It was nessassary to grind a flat on the motor shaft for the set screw.
It was easy to trace the motor onto the clear lexan. I cut out a few cooling slots, along with the monting holes, so the air could pass into the motor.
Due to the slightly lower rpm of this motor, I swapped out the 19ts for some 21ts.
PERFORMANCE......WOW "TORQUE MONSTER"
I am using a 60/80 amp throttle relay in this jeep. I have no idea how stock stuff would hold up. The 12 ga wire will all 4 motors running off it, gets slightly warm. The motors have not exceeded "warm" either
At one point there were two kids in this (about 80 pounds) in deep wet snow. Barely any straining and no slowing down. It became stuck at one point and the rear wheels (with traction aids) never stopped spinning! Those of you in the snow belt know what usually happens.....stall....SMOKE!
The gearboxes are ok so far. I do have the drivers start in low and shift up to high. The one time he forgot, the front tires lifted a good 6 inches off the ground.
I also think that they have so much torque that they are running at the "no load" RPM. A PW on flat ground does not load them enough to slow them down. This also means that they draw less than the advertised amps under "normal use".
If you have upgraded your wire/switches....and are looking for excessive torque....These are a good choice.

DRIVE IT LIKE YOU STOLE IT!..........Out of somebody's garbage
I'm trying to get out of PWs.........That idea's not working out real well......
My time on MPW is limited these days. I'm trying to check in everyday.....please be patient when awaiting responses.
