I'm going to convert my TTR S3 to electric and have chosen 6s Kokam 2400 mAh 30C batteries. For the motor, I was set on the Tekin Neu 1509/2Y/f with 1820 kv. This will spin around 40k RPM on the straight, geared to go just a tad faster than the nitros (using truggy bevel gears).
But, Tekin is recommending this motor for 5s and the 1509/2.5Y with 1450 kv for 6s.
I'm now in doubt which motor is better for me. I thought the Neu motors could handle 40k RPM easily and since the 2Y needs less torque with the shorter gearing, should run cooler instead of hotter. I want sufficient power for racing and long run time (efficiency).
Which motor would you choose for 1/8 buggy on 6s, 1509/2Y or 1509/2.5Y, and why?
Thanks for your help.

First, skip the 1509 for a 1/8 buggy. Been there, done that, and got the t-shirt. It will run a little hot. not saying it won't work, but your gearing will need to be PERFECT. You are much better off with a 1512 sized can.
In my experience, I find the Neus to run most efficient at around 31,000 rpm, at least for racing. You can easily run a Neu up to 60,000 with no problems though. I have run a 1512 1.5d on 5s with no heat probelms. I have also raced that same motor on 4s (49k) with no heat issues too.
However, I have found I get the best run time when I keep the rpms right around 31,000 rpm.
