Motors may be rebuilt as follows:
- Fasteners may be replaced with other fasteners of similar type and size
- Bearings may be replaced with any bearing of the same size as originally used.
- Sensor assemblies, end caps, sleeves, stators may be replaced with components identical in construction and function to that used in the original motor approval
- Rotors may be replaced with any rotor approved for the motor in question. Rotors from other motors or which have not been approved may not be used.


It's pretty clear that you're not allowed to put a different stator in there.

I'm sorry. I'm not sure what you mean? The stator/can isn't really good anymore once it comes apart, unless someone knows what they're doing to fix it. So a new stator/can needs to be purchased and you can interchange the endbell, sensor, rotor, screws, bearings, and timing ring which are exactly the same between motors.

I was told not to touch the timing but I'm getting a little bit of cogging around ~5% throttle. Should I play around with gearing? The HW motor I took out of the car ran fine with no cogging. The R1 motor runs fine past the initial throttle. Would it be a bad idea to run the car as is anyways and monitor temps?

(I am new to this and have no idea what I'm doing).
Sometimes cogging can occur by your ESC settings, I'm not familiar with your ESC but try disabling your fwd/reverse setting, or change the delay setting to minimum, even if reverse is disabled.

Default Is this normal?

Got this R1 v21 22.5 motor with a used F1 package off here about a month ago… I bench tested when I got and it worked..BUT working on the car today I noticed this “crack”? In the glue?epoxy?

Is this normal? Get too hot at some point? Will it affect its performance? To what degree?

thanks for any insight..

You can repair that with a little JB Weld. It is not really on a critical part of the stator, so it won't affect the performance of the motor. I do not think this was caused by a heat related issue, the coating can flake off after several runs caused by general vibrations. If it were mine I would do the JB Weld fix just to satisfy my OCD.

Appreciate the feedback, glad to hear it shouldn’t affect performance.

Do the new V21-S long rotor kits also fit in the older V21 motors. I'm thinking of replacing the rotor in my 21.5T V21. If the motor gets over heated, the rotor is the only think you need to replace to get it back in shape right?

Yes. They fit. However, there may be another reason fir the excessive heat.

Depends on how hot. If the epoxy coating on the stator windings has darkened, that may be toast too.
