!!HELP!! Gearing and the Jammin x1 CRT Truggy

[Jesse M]

I also want to run a smaller spur gear in my Mutilator (43/13) because the stock spur is just way to big for the CR mount. I was wondering where you guys found the Kyosho 46T spur gear and if it was steel or plastic. I'm also concerned about the Kyosho gear fitting on my center diff housing. I have a 50T Jammin CR spur gear and it does not fit on the Muti diff housing-the diameter on the housing is about 1mm too big.
Thanks, Jesse

Just wondering why you guys are opting to use the Kyosho gear and not the Jammin CR 48T spur gear?

Correction on my last post-I guess it is a 48T CR spur gear and I did get it to fit on the Muti diff housing with very little sanding.

i use a 46t spur in my jammin, and wow did it wake up after the conversion, way more off the line and more control in rythem sections.

Riverat, are you saying it 'woke up' after switching from a 62 to 46T spur gear or just the brushless conversion in general?

Couple other questions-

Why did you switch to the smaller spur gear?

Is there a benefit with the Kyosho gear over Ofna/Jammin 48T spur gears like wider teeth or something?

yea it seemed geared way better for the track after small gear conversion, i believe the kyosho gear is plastic which is why many opt for it for quiet running and longer pinion life. there is some shimming involved to make the hot bodies pinion work and u also have to extend the flat spot a few milimeters. but its worth doing and gives u more gear options. i run the hotbodies ring and pinion set and a 46cr gear and a 14tpinion and find it great at the track. just dont swap the spurs without doing the ring and pinions as i ran it a week that way and ended up snapping my motor shaft. but yes i noticed more bottom end and responce after the ring and pinion conversion
