Talion Gear ratios after tire change.

[Jeremy20081]

Im putting Inner diameter: 3.8" (96mm) | outer Diameter: 6.5" (165mm) | width: 4.1" (104mm) | Hex size: 17mm | offset: 0.5" (12mm) duratrax lock ups the factory tires are bead diameter: 4.13" (105mm) Width: 2.24" (57mm) Wheel hex size: 17mm Overall diameter: 5.75" (146mm) I did a RC gear ratios calculator an to get back to stock gear ratio I need to put a 66 tooth spur gear on it. I want to make sure this is possible an am I looking at this right.

Or should I do this. Pro an cons of both options.

I want to keep temps down but not Scarface air control when I jump it.

the largest factory spur gear is 50. If you are putting larger tires on it i'd drop to 13 or lower if 15 is stock. The spectrum/blx system won't like pushing those large whees/tires with a very large pinion on it. Also you'll want to check temps for sure. I used some belted 3.8 badlands on a kraton once and they felt big and clunky. I like the 4s outcast backflips on my talion for off road.

I'm running a Mamba monster x 1650.
