|  gear ratios
just see what everyone final ratio is....... If you dont know how to figure it out 1st gear = 2.76 (with 72t spur 3.1 G.R and 9t pinion = 194.4) 2nd gear = 1.72 (with 72t spur 3.1 G.R and 9t pinion = 121.14) diff = 2.84 teeth on spur = 72 or 64* If you running a pede/ruslter the trans ratio is 2.72 if your running a gd-600 GD-600 Ratios, 18t pinion = 2.5 15t pinion = 3.1 13t pinion = 3.5 12t pinion = 3.8 here to formula... (# of teeth of spur)/(#of teeth of pinion)x(trans)x(diff)=crawl ratio If you are running a gear reduction take that ratio ratio and multiply that to your entire crawl ratio. = your final ratio in which case I'am shooting for 124 final ratio with a 55t lathe |

you may have 124:1 but with the lathe, it wil be more like 160:1

| It's been a while since I ran a maxx, but IIRC, mine was somewhere in the neighborhood of 90:1. (and I used a lathe motor as well) -WRM |

i think my last setup with the gd600 was right around 120:1 and it was too slow..90-110 is fine.

That is the ratio was in my truck when I got it. Really like but since iam ditching trans which is a..... david engle trans and parts are hard to come by I'am switch it out to pede trans. I may try without the gd first and see how I like it. if not i can add on later or add and get mm motor for some speed.

i had mine at like 300:1 with a gd600, way way way to slow, took it to like 115:1 and it was fine, would have liked a little more wheel speed.

300:1 would be pretty dope with a 4000kV 8 pole brushless
