2200kv MMM

Hum, keep in mind that higher voltage means higher RPM so higher losses in the motor bearings.
But for heavy trucks like truggys or MT, with the 2200kV, 5S with small gearing is the way to go, maybe on 6S the motor loses a lot of efficiency in the bearing...
A 1520 1Y on 6S should give you better efficiency anyway...
Brushlessboy, I would have a question : The efficiency at full throttle is best for the motor or ESC ? Or both ?

I don't think you are grasping the whole point, or understanding what we are talking about...

When you go UP in voltage, you also go DOWN in gearing, resulting in the exact same RPM & Top-Speed as before...just with higher voltage.

So, going with higher voltage does NOT mean higher RPM since you are going with lower gearing at the same time. RPM remains the same with higher voltage and lower gearing, but the efficiency and run-time greatly increases.

No kidding
Read again what I wrote, I talked about MOTOR RPM, not transmission RPM

if you are at half throttle the fets must turn on and off a lot to "limit" the voltage in laymans terms.

but at WOT the fets only need to shunt power to the 3 phases and that's it, no more in-between-phase-switching.
