Project: Savage Flux 5T

Mmms, you'd need a different pinion for the front and rear diff. Instead of a 13 tooth pinion, you'd want to use a 10 tooth pinion. This would give you the same gear ratio with a center diff as a truggy. Or if using the bulletproof diffs, you'd need to run a 7 tooth pinion instead of 9 which would give you a 4.14 ratio so you'd need like a 47 to 52 tooth spur and a 11 or 15 or so pinion.

Basically you'd need someone to machine a replacement for parts #86031 or #102246. Or try and replace the diffs with something else. What is the ratio of the Cen diffs?

In order to run a CD would would need a lower KV motor or big spur/little pinions, which tend to wear out faster. Even on 6s with that motor, you would need about a 15/51 pinion spur combo and still push 50+ mph.

Uuug, more comlpications
Maybe getting the Flux trans to work is best then.
Thank you for the explinations on the gearing aspect gentlemen.
