Default 380 or 540 sized low kv high voltage motor?

I have a traxxas rally and a kontronik 10s esc lying around and thought it would be fun to find a low kv motor, maybe 1000-1500 kv to run on 6-10s lipo for a high torque, high speed rally build.
On a side note, anyone ever do a transmission delete center diff setup on a traxxas rally?
Thanks in advance!

You'll probably need to use an outrunner motor from a plane to get a kv that low. There is probably one that will bolt on, maybe an E-flite Power 15 or similar.

There is few options on 380 motors.

380 Sensored: Novak THREE-80 MICRO 18.5T - 4,400Kv - 82Watt

There is a few options on the 540 sizes.

540:
Novak Ballistic spec 25.5T - 1,550Kv - 82Watt

LRP stock spec 21.5T - 1700Kv - 148Watt

GM PRO 21,5T metal - 21.5T - 1650Kv - 140Watt

I don`t know about a lower turn 540 motor who is not a crawler motor.

I have some doubts about using a crawler motor.

Thanks for the input guys. Looks like all those are low voltage.
I did find these:

Looks like some of the 1110,1112,1115's would work. I think these are about the right size. Damn expensive though and I've not been able to find any for sale yet.

I entered some scinarios ink the speed calculator, looks like I need to go with a kv closer to 2000, maybe 1800-2100, anything lower and I'd have no more top speed than stock On 3s.
