With the help of some great ideas from members here, I have refined a way to easily alter the timing on can motors with a large tubing cutter. (camera is on the fritz)
Place tubing cutter on terminal end of motor and gradually cut through the can, this will free the brushholder (endbell) assembly from the can allowing you to rotate it to whatever timing you choose, whether it be increasing advance for ccw or cw advance for counter rotating applications.Various motors will have different thickness of a plastic assembly that holds the brushes and goes into the can, if you cut it right,there will be enough left to hold the motor together while you test run to decide whats best, after you determine that, fix the can back together with solder or glue. I think you will find it wakes up a lot of motors,my highest so far is a 42% increase in KV (with 8x4 airplane prop load) over stock. as you can probably imagine you will need to either prop down or drop down in cells with these kinds of rpm increases. This is not legal for 700 spec classes as you are now running a modified motor.
