Honestly, that one I cannot answer. I think it has to do with the rating of the motor, what it's capabilities are as far as amps, volts, etc. which may be due to the resistence factor in some ways. But the motors are built for certain KV's. There's a lot to this and gets real technical which I cannot get into. But, let's say for example you try the 10xl on 4s. It will run poorly and most likely get hot. Remember, you want the motor to be running around 30-35,000 RPMS technically, which 14.8 won't reach. Now, an 8xl on 4s would give you decent run times and what not. It's rated to handle or "do" the lower voltage, this is due the the number of winds...8 vs 10 and the kv rating...if this makes sense. I know it's a bad explination, but this is the best I can do without knowing all the technical stuff.

thanks for trying.
many thanks for that.
but i kinda start to understand now, you cant make a truck go slower then certain speeds with BL it seems.
so if i would want good performance ( temps, runtime, response time, ... ),
i have to get to a certain speed on a certain motor.
so on 6s it would work well with 10XL and on 4s it would work good with 7 or 8XL.
wich would now accelerate faster given the correct gearing and top end?
