XX-4 Brushless gearing help needed

I just bought my first 4wd and my first brushless motor system and I'm looking for some help in the gearing dept. At this point, I'm not looking to push the performance to the max on the system, I'm just looking to keep from overheating the motor at all - especially when I do 10-15 minute practice runs.

My set-up is:
XX-4 - unfortunately, I haven't checked the spur size yet - let assume stock at this point
Neo1 2 Star brushless with the Sphere Competition

I'm going to be racing off-road at what I'd think are smaller to mid-sized tracks. (If any of you are from the mid-west I'll be racing mostly at Chillicothe, MO & Ft. Dodge, IA)

Thank you in advance for your help,
Shane

Hey Shane, I'll be running at chilli some this winter. I run at novelty all the time. I just got the 5.5 and ran it with a 17 pinion and didnt have any problems. I would think for chilli I'd run a 14 or 15 its quit a bit smaller, at least thats what I'm going to try. Hope that helps.

You want to be running a ratio of about 13.00 which is 15t pinion 84t (kit is purple) spur. That was the advice from LRP at the recent European Championships.
Hope that helps.

Thanks for the input guys. I won't be running the XX-4 after all, but your advice should transfer well to what I will be running, a new BJ4WE

Thanks,
Shane
