Guess Medusa 36-80 it is. It's just that the mount I made for the XLB readily accepts motors with 4mm screws and a 30mm bolt pattern. And Mike doesn't currently have the 36-80-1600 in stock

.
Funny thing is, I'm getting a 36-80-1100 HOT in my Savage on 8s 3700. Granted it's geared for almost 50mph but still. The LT-10s ESC hardly heats up.
EDIT:
Another viable option will be the CC Neu 1520 1500 kv, when it comes out.
