Brandon Nebel Verified Owner Thursday, Jun 12 2025 (4 months ago) REDS VX4 540 “Pro Stock” Sensored Brushless Motor (17.5T) (EFRA) One of the best motors I’ve ran in a long time. Very high quality build and the gauss rating is close to what they claim at 1850, which means it’s got a super strong rotor and stator and is a super high torque motor. With a motor like this you can gear up 1 to 2 teeth on the pinion easily. When I placed this on the motor analyzer all 3 phases were incredibly matched wnd there was no deviation in the degrees between any of the phases, unlike the lower quality motors that have a few degrees of difference between the phases. I highly recommend this motor, you wont be disappointed. This has become my favorite motor dethroning the Surpass Rocket V6 which is another great motor at its price point.
