6 gears runner gearing chart?

[ra272]

Hi I want to race my RC10 CE 6 gear with a 19Turn quadmag Reedy. I have a 54 teeth diff gear and 2" rear wheels, what pinion should I use ?

Are use using newer batteries too, like 3000+mah? If so, use an 10 tooth pinion:

This won't answer your question but here is some info about gearing -


Car Transmission ratios : (according to a Twister Motors spec sheet)

RC10 w/6-gear - 1.85:1
RC10 w/stealth - 2.25:1
Dominator - 2.25:1
M.I.P. - 2.00:1
YZ10 - 2.33:1
Losi JR X2 - 2.18:1
Optima/Ultima - 3.00:1
MID-Optima - 2.64:1

I was running a 10T with a robinson 56 tooth spur and a 19Tspec motor and I could pop wheelies if i used a bit of reverse then nail the throttle...it was fun to do but hard on the rear skid plate lol. Anyways the top speed wasnt so good so i switched to a 13T pinion and a 50T spur and the top speed is awesome. I dont think I'll gear any higher than that unless at the track something changes...

Thanks, the B4 gearing chart said 9.57:1 for a 19T spec, my CE has smaller wheels: I will try to gear it 9:1.


I think I have to found a 11 teeth pinion....

First run today



I ran it with my Reedy Quadmag 19T spec, I finally used the 14 teeth pinion: on an indoor carpet track, it was a very good ratio.

It was the first time I ran a 6 gears RC10, it was very fun (and noisy ). I was surprised by the overall good performance of this car (compared to my T4), on a carpet track.
