Ok, have done some testing with a variety of setups.

First thing, the sx27 is slightly longer than a feigao 540 s can. The rcm heatsink/clamps for the s length motors fits fine. The sv27 motor has pinned on end caps, but they are not on that well, so the clamp is a good idea.

The motor does not lik 5s, no matter how low the gearing is, it just heats up too much. 4s is much better.

My most successful setup is in the LS10 on 4s lipo with a quark 65 esc. Plenty of power, using 3600 12c 4s lipo (poly rc). This is the same lipo that I use in my supervee boat.

Ls10 setup with 14/54 gearing runs about 30-32mph with the sv motor on 4s lipo. Not really all that fast, but it has tons of torque. Motor and esc did not go over 140 deg f and battery stayed at 100deg f.

I will gear it up to a 16t, which should be good for 35mph or so. We will see how it holds up.

This motor definately likes the water cooling of the boat, it is never hot even after a 15min full throttle run. I guess it is not very effecient, but has way more torque than a feigao. Not sure what it would be best to use in, maybe a lightweight 4wd truck like a crt.5?
