ORCA R32 Electronic Speed Controls

Where can I download new firmware as it becomes available for my R32?

 I was a big fan of the VX3 Electronic Speed Control - is the R32 its replacement?

  • The ORCA VRITRA R32 Competition ESC is the follow-up to the popular VX3.  

    The new ORCA VRITRA R32 features all new hardware and firmware.  The hardware improved by 4X through the use of a new 32bit CPU and new circuitry.  The MOSFET design delivers 40% less resistance.

    Firmware improvements have also delivered an ESC that has more detailed and direct programming parameters which means you get more exact control of the brakes, throttle, boost and timing that make drivability and power more exact. 


    • Next generation 32bit ultra speed 4X CPU
    • 40% lower resistance than the previous models
    • State-of-the-art, newly developed board architecture for quicker and smoother response time
    • Completely new design firmware for easier hardware tuning
    • microSD card support for easy updates
    • ROAR Approved
    • Part# OES833VG
