I am running Team Associated RC8TCE, RC8Be, and SC10 4x4 all with Tekin Systems, and there ain't no way, that the equivalent Castle Systems are as smooth, and powerful as mine on the same set-ups (not including Steve Neu motors). I used to run Castle, but now only run Tekin. There is nothing else like it that I have tried with equal performance and ranges of motors for 1/10th and 1/8th Scales.
