Motor question slec 47" huntsman
Hi
I was going to replace the 850 brushed motor in mine (but then sold it) with either an Overlander 5045 720kV or Leopard 5055 650kV (from The Component Shop). The slightly higher kV over that of the motor specified with 500kV means that you can come down on the battery voltage - 4S would give you around 10k. RPM which will give good speed. Both of these motors require a minimum ESC of 80amps.
Motors in this size/spec are few and far between, unlike with the plentiful 28 and 35mm diameter, and these are the only ones that I could find. I would have gone for the Overlander as that is my standard choice for my builds and has a higher kV.
