A bit of info please (savage conversion)

Hola amigos!

Been bashing with some colleagues during spring. They drive nitro savages and Ive been driving a brushless Tamiya buggy (Baldre). On flat ground Im faster and has better handling... but whos bashing on flat ground? As soon as we hit some rough off-road action Im left in the dust... and often with some broken parts! Ive lost count of the number of times Ive been told that batteries is what they use to start their nitro engines.

Now its time for a change!!

Ive bought a used savage chassis on e-bay & the eZrun 150a ESC + 2000KV motor combo.

I plan to lock the transmission in 1st gear (same as the flux gear ratio). In order to fit the motor in between the TVPs Id like to run with the smallest possible spur... but will the flux heavy duty spur fit the standard savage transmission (Id guess so but dont want to order it if it wont).

If/once the standard transmission break down Im guessing the easy route is to buy the flux transmission from a chop shop on e-bay... or?

Another question for the pros: What tooth count would you pick on the pinion with a 43t spur and a 2 speed tranny locked in 1st? With a 22,2volt setup and a 2000kv motor that is. Im not really looking for crazy top speeds...

Battery tray and motor mount will be home brewn... we have a really nice workshop at work :)

I did consider running this setup with 4 cells... but would I be able to trash the nitro guys (4.6) with the ezrun setup on 4 cells? 6 cells will most likely break gears and flip me on the lid.
