Wanted: Brushless Motor for a 4s - revo setup

[Gee]

Thought I would check for any deals. It will be put in a e-revo running a mm/bec on 4s. It's not going in one of mine so I am open to anything that would work.

He lives close though so it needs to be able to keep him happy for a little while.

I might let go of one of my motors to him if any one has a decent motor that would be good for a 6s in a heavier Savage XL or LST2.

So
4s motor for revo size rc
or
6s motor for savage xl size rc

Thanks
