From Gravity RC:
The USVTA would like to announce the availability of the new USGT Spec 21.5 racing motor (p/n GRC2000) from Gravity RC . The motor market for spec racing has become more competitive and ever changing, and challenging for the racer to navigate. As such, handout and “equalized” motor formats have become popular recently, so the USGT Spec motor has been developed to address the concerns of racers. The motors are fixed timing, with no rotor tuning options. The motors have “USGT” etched on the rotor shaft for easy identification. The motor can is also boldly marked with “USGT” lettering.
Each motor is inspected by hand for adherence to tolerances in a number of categories. Motors and motor parts outside the range are rejected before the motor ships out, ensuring quality and close standards of performance. Stator resistance, motor timing, sensor asymmetry, and rotor alignment are all variables confined to a small window to help equalize each motor.
All official standards for these motors will be published on the USVTA website shortly.
This motor will make it’s race debut at the US Indoor Championships in Cleveland, Ohio this Thanksgiving as the control motor for USGT, but racers and clubs that would like to use the motor can purchase it now from Gravity RC. The USVTA will adopt this motor as the official USGT motor in the Spring of 2020, to allow racers plenty of time to transition from the current crop of 21.5 motors.
