Considering trying out a 550 sensored brushless motor. Currently running a 540 7.5T (4700kv) motor. I'm trying to figure out what pinion I would need if I went with the 550 motor in the same application. The 550 motor I'm looking at is also rated as a 7.5T but the kv rating is 2650.

I'm currently running a 17-tooth pinion on the 7.5 540 motor. What would I need for the above mentioned 550 motor to get similar performance?

Thanks in advance for any insight!
