I think a Feigao 8L don't will be a good choice for a savage.
It will be work very very Hot and so will be Mamba Max and Intellect Battery also.
Moreover, you'll get cogging that is very dangerous for ESC (a friend of mine fried a Mamba cause cogging) and annoying while driving.
I think best motors for a Savage should be XL series because have more torque of L series considering that the savage isn't a lightweight truck (more of 5,5 kg RTR).
I used a 9L on my savage only for little time and now I'm using it on a buggy 1/8 that weighs 3,5 kg RTR and works great!

I think you may consider at least a 10L or better a 9XL.

Lipo are however strongly advised.
