its always hard to recommend gearing to someone.... first of all will you be racing? bashing? etc etc. Also what spur gear will you be using?

Cheers

Will be using the standard 72 tooth pinion. Wont be racing as there is no track in my town but probably just parking lot racers with my mates. I think it comes standard with a 17t motor running a 23t pinion but I bought it as chassis only

If you really want some rip with your TC4 try a 66t 64 pitch and a 45 through 50t pinion.Tats what we used to run blacktop and carpet.And that will work great with a 27 or 19 turn.If you want mre run time try a 72t 48pitch with a 35 pinion.Hope this helps.

35t seems pretty big, the standard rtr comes with a 17t motor and a 23t pinion with the standard 72t spur

In the manual it recommends a 30t pinion for a 19t spec and 27-28 for a 24-degree stock motor. Is the Peak 15x2t motor a stock motor?

No the 35t is not very hot for racing,thats why I said if he wanted more "run time",not speed,if he is just bashing.

I have been racing my TC4 in club races and I usually ran around a 21 pinion with a stock spur and a 27 turn trinity motor. I am putting a 13.5 SS Novak system in it, what should I consider when switching to a brushless? Should I consider changing my spur gear to a smaller size? What are the advantages?
Thanks
