HS-55 Pan System Holder
Servocity sells a really nice pan/tilt system for small cameras. I purchased one and really love it! What I needed was a way of attaching it to a model, and better yet, a way to move it from model to model.
This thing is a holder for a HS-55 servo which forms the base of the pan/tilt mechanism. You can bolt it to you plane and everything moves nicely. Friction fit of the servo is decent, but I added a little wee glob of hot glue to make sure nothing moves.
