Idler Gear Set : Recommended Motor / Gearing?
Just received one of the new idler gear kits from Atomic Carbon. Seems like the smallest pinion that can be run is 25T - is that correct?
I'm wondering what kind of pinions and motor setups are recommended for this. I'm primarily running on a small-medium technical dirt track which is generally medium-loose in grip. Thanks. :) |
i've got a 23 on and im pretty sure i could go smaller. Are you using the morot plate or did you drill your own holes?

I got the same idler kits and with any pinion smaller than 25, the motor screws will foul the idler. See pic.
Also, do I have to mod the stock losi gear cover if I want to use that? |
8,5T motor, 25/78 gearing, just perfect :thumbsup:
Btw: I ran the car with a 24 pinion without any issues... |
Put a small spacer behind the idlear gear to step it out a touch? I havent got a kit so i dont know. So the motor screw can sit slightly behind it.

I have ran an SP V3.0 8.5 with 23T on my CR2 SE would have a larger pinion if I was running outdoors. It went very well.
|
hmmm actually i lied...its a 22 just looking again, but the screw squeezes under without fowling because i have the red carbon motor mount which has a small indentation so the screw sits further in.

Thanks to all who shared their input. I'll try some of the ideas suggested and report back! :)

You can do two things:
put a spacer under the idler post so reaches out further. But that's probably not the best idea because then you get less overlap with your spur. Dremel your motor screw head to make it flatter, and don't use a very thick washer. That way the screw will fit under your idler. You do have to remove the idler to tighten this motor screw! Wouter |
There is 2mm clearance between the motorplate and idler gear, either a button head screw or a countersunk screw with a countersunk washer will be fine.
If you space the idler post the idler gear will not be meshing fully on the spur gear (ie only part of the spur will contact the idler gear) which could lead to extra wear and it stripping. |
These solve a lot of issues and are favoured by some of the HHUK team!
