are you sure about a 128T and 45T? And why go with the bigger spur and pinion? It adds extra rotational weight. Reading this site, the TC3 guys are having a roll out of 26-27 on the CO27. A 128T with 45T we'll get a rollout of 32. Which is similar to my 120x41 gearing on my P2K.
I'm running 120T and 41T on my old P2K motor. Too bad TCS in Canada is restricted to the silver can or black can motor. Not sure how that is in the USA. But I would like to get back into GT2 TCS. Any tips on gearing for the black can?
I rear your thread on the brushless and it looks like we're running similar setup!
I like this car, too bad it is being replaced by the TA05. Funny how my stock TA04R is lighter than a stock TA05 (approximately 100-200g lighter). Although I do like the battery layout of the TA05 (reminds me of my Yokomo MR4-TC).
