Thanks guys for the help. I was assuming that the Feigao 380c 6L was a 6 turn equivalent motor thus being much to high rpm for a 3 cell lipo. For my revo I am thinking 1940/9. On the rustler I am still up in the air. I think for the rustler its between either the BK 10s or the Feigao 380c6L. The 380c6L looks amazing for the money but the question is....is it low enough rpm for a 3cell lipo?

If you go here you can see the packs I am using

I have the Lipoly 6000mah 3S2P 11.1V Pack for $119.99.
Rated at 60 Amp Constant Discharge
Rated at 72 Amp Burst for 10 seconds
I hope that battery pack has good enough discharge for what I need.
