My second Xerun v2.1 ESC. Great product ! I use it on a SC10.2 Short course and it has far enough power to handle every track conditions.
The picture shows a v2.0 ESC but don't worry, you will receive a v2.1 !
Don't forget to update the firmware and put the v3.0 which brings some new features and better reliability !
I have 2 of these ESC, the Black one and the TRF Blue one. I run only mod class and this ESC is excellent. However it lacks rpm on high side this will only become obvious if you are running on a track that has long straight, not a problem on small to med size track. The best thing about this ESC is it can run sensored or sensorless motor, even if you are running sensored motor and somehow the sensor wire detach itself during running, it will still be running as if nothing is happening, it will switch itself to sensorless mode. One more thing, this ESC is the easiest to be set, no lights to be counted and no PC is required, just plug in the card and select whatever set up you want. Overall a very good ESC.
I have the blue version of this speedo fitted in my TC5R for racing, and it's a very good speedo. The programming box is a very good idea, as is the optional kit to link the speedo to a PC. I have just downloaded the latest firmware, and it has made a vast improvement over running the previous firmware. My motor (Speed Passion 13.5t) runs lots cooler now, and also has higher top-end. The speedo is far better than my old GTB, far easier to set up and has lasted more than 2 months without catching fire!
