I was a die hard 4s guy, but I never ran anything higher than 2050 kv.
I settled on 4s and 1900 and had great run time and the car was great on the track.
I have taken the plunge and moved to 1400kv and 6s. I have not driven my car yet with this set up but I hope it is smoother on the track.
It seems that it will have more RPM with the 6s
14.8X1900=28120
22.2X1400=31080
I gues I should run a smaller pinion?
I run 15/46 on 4s
What would you guys sugest for 6s?
