Default Novak GTB with 13.5 motor on 2wd Slash

Ok i have a question if i can use this motor on my 2wd slash ? Its the first generation of the brushless Novak motors . I just bought a 32 pinch jato spur gear conversion and i only have a 10t , 11t, 12t.

But i do have my 48 pitch spur gear and pinion as high as 21t .

How many teeth are on your 32p spur gear? Is it like 54t? If so, even running the 12t pinion you will be a little undergeared, but it should work ok. Just run the 12t pinion and keep a close eye on temperatures on both the motor and speed control, check it every three minutes in the beginning and don't let temps get over 160F.

About 3 teeth on your spur is equivalent to 1 tooth on the pinion. The bigger the pinion the More top speed less torque, bigger the spur the more torque and less top speed. If that guy recommended a 12/54, than a 13/58 would be really close.

Ok got you i dont have a 13t pinion inless my Lhs does i do have a 48 pitch spur gear and pinion so i think a 18t or a 19t or 20t whould work good . I race on a tight indoor offroad track with a meduim size straightaway.

I know that usually brushless motors are geared higher than brush motors usually.

I got the ballistic 13.5, motor timing at 38-40 degrees, I'm running 21/86 I think. I will check when I get home. I race on a 13sec indoor, clay track. Start off with a 19/90 if you can.maybe a 20. But check your temps for sure.

Ok well i have a 86t spur and do have a 21t but i think a 20t whould work the best on a tight indoor track though.

The track im bashing/racing at will have carpet also.

With that 20t pinion and the 86t spur, you would be under geared about 4 teeth on the pinion. Might even be able to jump up to a 26t pinion....

Dam lol thats a big pinion i dont even gear my E-truggy nearly that high but that is diffrent though. Ok il try a 21t and see if my Lhs has some 32 pitch pinions and some higher tooth 48 pitch pinions.

hahahaha.... I am running 36t pinion with 91t spur in my tc, that's a 17.5 though....

If you have an i-phone, or any smart phone for that matter, get the novagear app.... It's pretty good.

This works too...http://www.rcgearhead.com/Gearing/Browse
