800 motor kv?

[DaveHolland]

I am not building a Trekker 800. I have the availability to run 12, 13 and 14t pinions with a 121 main gear. I have calculated and with the 12t I could run a 530kv 750mx. Would 530 be a good kv or and I looking for lower. I am speculating my head speed to be around 1750 and I want a top end of 1900. What motor would be the best choice for power for 3d? I would however like to keep the price under $250 for the motor alone.

do the trade up on the 750 motor to a 800mx with the lower kv setting run the numbers to make sure it fits what you want to do for head speed

I am looking to run 1950 and it will get there with a 12t pinion @ 520kv. Though I feel that I wont have the torque required with that high of a kv.
