I tried it out with a 7 turn .
The Astro is for my 'steath drive', it is a lot quieter than the outrunner. Not sure what it will end up on yet.

Edit- While I was typing this I left the motor running about half speed in Delta with no load and it got very very hot in about 5 minutes -like water boiled off when the outside was made wet! (it is now cooling down wrapped in a wet rag ).

atleast that is my experience with these motors when i was playing with rc cars

Not if it's a good motor (or running at too high a voltage)
