Within a few weeks, I will be able to tell you how the RB T10, not the T10RC, keeps up with a Flash .12 Tuned. I guy I know recently got one, so once he breaks it in and I set up his car for the track (recently got himself a RRR Evo1 WCE) Ill say for sure how they compare.
I will tell you, if you don't have the low-end set right, it runs pretty strangely and feels like you have a little less control over the engine. Once you have it right, the response is picture perfect! Just some insight to the T10
