They are pretty awesome, but what are the extra spacers and o rings for?

The shims are in case you switch rotors and lose some or want to try and shim it differently.

Not ready to release these as we still need to figure out how to optimize the stock motors. Waiting on some new samples and also need more info from ROAR as the current rules are not clear.

Just added a Bearing section to our website. We offer 4x10 regular and ceramic hybrid bearings which is the size used in our SM-1 motors.

The rotors are 4mm/12.3mm which is very similar to a 5mm/12.5mm rotor.

Just pulled my motor apart as it is making loud whining sound in forward, but quiet (like I would consider normal) in reverse. I didn't see any shims in the motor, but the rotor does have some play in it. Is this movement what the shims are used for? If so, do they go on the front or the back of the motor, or doesn't it matter?

Thanks in advance.

Is this a SM-1 motor ? If so there should be an aluminum sleeve on the rotor on the tops side and a small shim on the bottom of the rotor.

SM-1 7.5T. Here is pic of what I have.

Put the motor back together and the whining sound is now gone. Bearings spin free, not sure what it was. I did have the motor apart once before for the same noise, so it is possible I overlooked something then as I'm new and never done this before.

Just add the smaller shim on the bottom. Could be some small debris that creates the noise.

Are these motors louder than other brands? I just installed a 7.5 in my Serpent buggy and it sounds like I am running a 1/8scale steel drivetrain. It also reminds me of a Castle 1/8 BL motor with it's strong loud magnets.
