Converting a Savage

[Rtsbasic]

To maintain battery compatibility with my other cars, I'll likely be sticking to 7 cell packs with my 9XL. So shouldn't need too many drivetrain upgrades?

Any chance my Emaxx strobe will fit on? I don't really need it on my Emaxx, and its almost new.

What sort of pinion do you think I'll need on 12-14 cells? My plan is to leave the car as stock as possible, from what I've read and seen its very durable for bashing and jumping as stock?
