Hello All,
I just recieved my LCC (first rock crawler) and electronics. I was surprised to find you do not get a pinon gear with the kit. I have searched/reviewed many posts about suggested pinon's but nothing really says what pitch it has to be (I'm assuming 48P). Sorry for the dumb question, if someone can give me a little insight it would be greatly appreciated.

thanks

yep 48 pitch ranging from 12 to 17.I started running a brushed starter boz motor with a 12 tooth then changed to a brushless 18.5 with a novak crawler esc for a 2s lipo,but am going to go up to a 15 tooth for more wheel speed.There are plenty of threads in here about that subject.Enjoy your LCC,i know i do

Yes it's a 48p. As for the tooth count it just depends on your motor of choice. I ran a 35t warrior with a 15t, didn't have enough wheel speed, motor got hot, and run times sucked. If your gonna stay shafty, brushless is the way to go.

Thanks for the help

what happens if you try and use a pinion larger than 17? i have a 21.5t goat with a 2s battery. i initially bought a 13t pinion, but now i want more speed. the motor is in the shop currently, but i have bought a 20t pinion thinking this would be the solution, at least for now. will i be able to use it, or is it too big?

I run a 13t on my 21.5T and can see that a little more wheelspeed could be nice. I can still blip the throttle to pop the truck over obstacles so I haven't bothered to change it. I've seen rigs with so much WS that it gets them in trouble, once they overshoot, they are screwed!

I would only suggest about 14 or 15 to keep the motor running cool...20 sounds like it would heat it up. This is just a guess and an assumption from what I have read.

If you try it, let us know although I wouldn't want that much WS, just a tad more than the 13 gives. I would go 15t at most.

Oops...I am running 3S...maybe the 2S is much slower than mine so I guess I'm not comparing apples to apples?

yeah, a $3 pinion is easier to experiement with than a $30+ battery. 21.5 with a 13t pinion is just too slow with 2s

i run a 12t pinion with my 18.5t goat and its awsome (i run 8.4 volts) but it could use a touch more wheel speed from a 13t or more volts

A 15T would be pushing the limit. A 20T would just be way over the top. Unless your just driving it on a ice hockey rink.
