IF you can turn down the Mura endbells per my article you can also use the Slot-It 26k-29k arms from their motors. They come with the better cummutators, to get a rebuildable motor and brushes. They are not that fast for the homeset cars and do a good job for me.
If I need a hotter arm for it I then rewind the Slot-It arms to what I want. You can also just put the Mura endbell on the Slot it can, so you don't have throw that away. That gives you a shorter over all motor that fits in places better than the Cheetah/Falcon can, which though, also can be shortend if you want to.
Here is a shot or two of the motor and parts.
