Hi All

Is there a big difference between the 700mx and the 750 mx Motors
I have the 700 motor in mine and have a friend that has a 750 for sale is it worth changing it over

Lower kV can mean lower Wattage but I prefer 480kV over 530kV because it has more torque. It means RPM is more constant and without governor flies better.

If you want high RPM you can chose higher KV with governor. Higher kV gives you more headroom for governor in power hungry situations. You simply can have throttle curve lower to get high RPM.
