i run the LPF version; very very good, lots of adjustability, but as bigred rightly points out, you got to watch the amps going through it.
I am nearly at the limits of my motor allowance with the 6.5 in it now; and with batteries getting more and more current, the LPF can just about go to a 5.5 turn motor, so if you want to run motors like that, then the PRO is defo the way to go.
...oh, one other thing I didnt know when I bought my setup is that if you use a SP GT esc and a SP v3 motor then the esc has a temperature shut off for both itself AND the motor. Nice
