After a little testing...
The lowest ratio i could get was a 56/11 (5.09) on the stock spur.
If you remove the spur gear cover/backplate you can swap out the stock 56t spur to something larger.
The Associated SC10 4x4 spurs are 32p and available in a few more sizes.
The will require the AE slipper pads.
# 91170 "high torque slipper pads"
# 91096 is a 58t spur
# 91095 is a 60t spur
I have a 62 tooth, but I wasn't going to shoe horn it in there.
The larger spur allows me to go to a 10t pinion too.
58/10 = 5.8 ratio
60/10 = 6.0 ratio
I can now gear down my mid level KV motors for better crawling, and more torque (that I do not need)
This can equate to about 15% reduction in overall drive speed.
I don't run a gear cover, rocks, grass & dirt just fall through the teeth, but is a little noisy.
