Agree, did not compute in my pathetic brain until quoted.

What about a 1527/1500KV motor on say 8s with a CD, the gearing will still be ugly high for the application ?

Most definitely. 44,400 rpm's and a fast FDR sounds like a high speed running rig. The standard flux f/r diff ratio is 3.3 and the bulletproof is 3.22 so they are relatively high speed compared to Truggy(4.3).
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.

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?

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