jammin x1 crt gearing

anyone running these know the best combo for the 62t spur?
About 10t or 12t. Running the hobbywing 2350kv motor, on 4s 25c pack

id say thats about right maybe a 13 or 14 just watch ur temps,

well it will be on a track so top speed isnt a must could it be geared lower?

u dont want to go too low as u will hit the center brace with the motor id say 13 maybe 12 is as low as u can go, sorry i didnt mention that first but it just popped in my head

thanks

i just got a jammin x1 crt with jr 8711 steering servo // mamba max 2200 motor and speed controller 5 cell 4000 mah 35c lipo battery.. zeilke racing body andand spare 3 size pinion gears truck was clocked at 70 mph on a wheelie insane speed also with spectrum receiver 2.4 dsm 2.0 controller

u must have some great tires,

I had a 13t on my hobby wing system in my CRT and motor was 150deg/f and lipo's 115deg/f and esc 90deg.So went up to 15t and motor was 145deg esc and lipo's round 90deg/f.So going to try a 14t this weekend and see.Should be sweet spot I think..BTW i'm running the 2300kv HW system on 4s!

But getting my Tekin RX8 tomorrow with 2050kv motor.Think 15t will be good there!

on 4s i would gear around 35mph for best efficiency and cool temps, the bottom end power will not draw as many amps

Why would you want to use such a small pinion gear with a such a huge spur gear. I have a 17t spur with 62t Mutilator spur gear with 2300kv motor and 4/5s and its is dam slow.

[riverat1540]

you are geared for 47mph on 4s and 60 on 5s not including tire ballooning, i think your system is under too much load to get up to speed if u think it is too slow with a 17 tooth pinion and a 2300kv motor, i used a 14t pnion on the 62spur with factory diffs on 5s and neu 1515 1y geared for about 46 and it was plenty fast and was not under alot of stress , cool running setup. also the reason to use a smaller pinion with such a large spur is that the crt x1 has buggy diff's in it and does not use the truggy diff ratio which is why it uses the large spur.
