Volts do not matter on brushless, it is the amps.

16 thumbs up!
Very powerful motor, but actually not suited for usage without good cooling.
The motor gets hotter and hotter with and without load.
I'm using it with a silicone cooling jacket in my micro outrigger. After 5 minutes of driving at about 30km/h it's just handwarm.
Setup is a small 750mah 3s Kokam Lipo, and a Turnigy plush 12A ESC.
So a good and powerful motor for usage in boats.

2 thumbs up!
powerful motor, works good with CC ThunderBird-18. I tried TowerPro MAG8 ESC -the motor gets too hot to touch even even if turned off. It seems TP ESC only usable with outrunners.

These get so hot! Did want it for a pusher prop but without being prop cooled will have to make other plans.

1 thumbs up!
Used this on my mini slinger too and burned out 2 of them within the first flight each. I bought 1 third one and this time used a 7.4v 2s 1300mah battery instead of a 11.1v 1000mah battery and it works perfect! It doens't get hot and more importantly it doesn't burn out! BTW I am using a 4.75 x 4.75 prop on the mini slinger. This setup is FAST and I don't think you can have a more perfect setup with this mini slinger plane.
