In the end, they are very very very minimal differences.
And for the record....it's a 100% illegal to do on any stock or 19t motor under ROAR rules....while one could argue that polishing the shafts is the same thing, there is absolutely no way to tech it......
I understand the physics: less centrifical force.
Has it been proven on a dyno? Under a load, if the mag poles of the arm are farther from the magnet, wouldn't it less torque; thus reducing the arms ability to push that load to a higher RPM?
No modifications to the physical construction of the motor can, endbell, or armature will be permitted (e.g. adding or removing material from the armature stack, changing brush hoods from stand up to lay down, etc...)
This may sound stupid, but then wouldn't turning the comm be a violation of this rule. It is "removing material" and it is a "physical alteration of the armature"????
OK, maybe thats just "rant"...
