I'm getting alot of questions about the "Short Stack" TSR 17.5
Here's a quick run down:
Original motor : 19.8mm over laminations
Short Stack : 19.3mm over laminations (only 1 lamination was removed)
Original motor : 21.4/5 to 21.9/22.0r
Short Stack : 21.2/3 to 21.5/.6r
We're using the same rotor combos, just a few degrees less timing now.
RPM's are up across the board with the Short Stack.
This is an ongoing change, not a "new" motor or "another" motor
