Hey Saris,
With the Savage XS and the dual battery configuration which can run up to 4S. We don't have a system rated to 4S, even in the smaller Savage XS. The Copperhead system coming out in November is 2-3S only but will have no problem pushing the little Savage around. If you plan on just running 2S the VX4 or VX4R's will have no problems. The VX4 is the 3.17mm shaft size and comes in 3900kv and 5200kv, the VX4R's are the 5mm option and are longer than the VX4's at 62mm length.
I would not suggest using the 2 pole motors and VTX10 with this setup, while it's not been tested in the Savage XS, it would be fair to say you will want a little more flexibility for bashing.
If you have any questions feel free to give me a call 425-985-0655, my name is Trey.
Thanks!
