I haven't run a motor that needs to geared that low in a long time and I can't remember for sure if the 12 fits. A 13 will (with the old mount) and gives you the same top speed as a 1900kv motor geared 18/44. A 14 tooth is a little faster than a 1900 geared 19/44.
Alright, I see, thanks for the detailed information. Yeah, I guess I'll experiment around with it when the day comes and I hope that 13t pinion should be sufficient, I run 12t pinion on 46t spur for this x-ray xb9e. 12t pinion is more than fast for it. I probably will have to go for 11t pinion. Or maybe switch to a 46t spur if it even fits in eb48.3
The worst case possible would be for me to sell the motor/ESC and eventually get 1900kv motor and go 18/44 or 19/44
Thanks RCmatt, I am going to look that up.
