just wanted to get you guys opinion... i have both the xerun 120a 3.5t 9100kv combo and the castle creations sv2 6900kv 4pole combo.. in my on road touring car... ive tried both in the exact same car with exact same gearing and battery pack.. i havent tested this with a spped gun or gps yet. but by the look and feel of it my castle system is faster, isnt the motor with the higher kv supposed to create more rpm thus more speed?

sonspit

never mind after getting to know the xerun and all its features.. its a great combo, dont get me wrong so is my castle.... i will test the actual speed and post results....

The 4 pole is a high torque motor and it will need more gearing to make it work like it should.

i have them geared the same, and my 6900kv seems faster.... why? does 4pole make that much of a difference?

Best results would be the Castle motor behind the XE Run speedie!

ithought about that!! but i want to try every option available with the 3.5 motor first to make sure i got the most out of it and the castle motor ran very very hot! but eventually i will test that out

Being a 4 pole I would have expected the 2 pole 3.5 motor to run hotter of the two.

me too. go figure, after i updated the mod firmware on the esc it ran very cool... only gets skightly warm after a hard run
