I have seen pics of them but dont know where to get them, they look like basically a box, or I have seen round ones, that you glue into your model and the servo goes into them and you screw the cover on, look like a great way to mount aileron servo's and what not.

I appreciate any help or links.

Hobby Lobby/Graupner, Hitec and others offer these servo boxes.

You can easily fabricate these as well with aircraft plywood.
