It's an awsome speedcontrol. It runs great with any brushed motor and runs flawlessly with the Tekin Redline motors. I reccomend to run the 448 or 537 in 2 wheel mod buggy. Have not had the oppurtunity to run any other brand motors with the R1 yet just playing around only. There has been some issues reported that cogging and hesatation is there with other motors and that hardware is available to make it smoother with the other motors. The Hotwire is available to keep up with all the latest updates and you can change the timing characteristics of the motors with it also.
