Minimizing weight as much as possible is what ultimately brought my search to the RC world.
Thanks Joe, understand now.
Just checked the Motor and it runs at 1800 watts. (Surge to 3600 watts)
With 12S (around 50 Volts) you will need an ESC that can handle 12S and 60 amps. (80 would be better)
As for controlling it. The servo driver you listed will work but requires a separate 4.8 volt power supply (a typical RX flight pack like
one of these )
If the ESC has a BEC then it will power your Servo Driver and you won't need the separate 4.8 volt pack.
Hope that helps.
