i have a quick gearing question...
im running a xxx-s graphite plus with a kevlar 128t 64p spur gear...
i have 2 motors i want to run i have a 19t reedy quad mag motor and i have a teamcheckpoint 10xdouble...
my question is this i just want to know what pinions i should run on that 64 pitch gear i called losi and they like blew me off and told me to look at the manual....but what they dont know is the manual dosent show 64 pitch gear ratios so my question is what pinions should i run with my 19t and my 10t on my 128t 64p spur...

Pick your car and spur here. You can print out a gear ratio chart, then compare the ratio number to what the manual uses.

Like the 2nd post said, gearchart.com will do the trick for ya. But, on a side note. The reedy 19 turn should be geared around 5.6 to 5.9 Not sure on the 10 turn. You may also have a hard time fitting the correct size pinion with the 128 spur gear. PRS use to make an adaptor to fit on the xxxs so you can run regular spur gears. If not, you should be OK with the losi green colored spur gear for the proper gear ratio's.

i just like the smoothness of a 64 pitch over a 48... a 48 pitch feels like a stadium truck to me the way the acceleration and drag on it so... lol

You won't have an issue running any pinion with a xxx-s. The motor cam moves over such a wide range.

You will have a problem with the 128 getting to 5.6 to 5.9. Losi also sales the xxxs spurs gears in 64 pitch. Three different colors. red, green, and blue.

Yes...3 colors in 128, 118 and 108 (I believed)...I have a red alum adaptor and can use with any Kimbrough or Robinson spur gear...I think XXXSG still a great outdoor rubber/foam cars....I am keeping her for the 3.5 brushless outdoor foam outdoor outlaw race...parts are cheap, and car is strong.

For something like 10T (mod)...I would think start with 11 and up. like 21/128 and check the speed and motor temp. However, if 21T is too tall, you might need to lower your spur to 118T cause I don't know how many pinion you can buy are less then 20T...(I don't have pinion that lower then 22T)
