I have a gear/wheel assembly that I pulled out of an old junked VCR, and I am getting a mini cam to put in my plane. I want to make the wheel into a camera turret, but have a lot to learn about RC hardware. I have yet to buy my first 6 or more channel transmitter. (I've been only flying Aerobirds and Firebirds so far). The idea is to turn the wheel with one a gear on one servo, and control elevation with a pushrod through the hole in the center of the wheel. The pushrod should be easy, but the question is: What kind of servo gets the most rotation? I would like to get a full 360 degrees of rotation out of this without too much fiddling with gear ratios. How will the programming in the transmitter affect its behavior?

The need for 360 degree rotation... ???
This requires a very special airplane.
Tilting and panning is relatively simple to do, with two normal servos, if the range of motion is restricted to a useful amount in both axes.
From level to straight down for tilt, and full right to full left for pan, although straight ahead to full right or left is easier to do.. Just turn the plane around to look on the other side.
The photographer will be very busy, hand-eye coordinating all this movement.
I use a 90 degree tilting mount, with changing the airplane heading for the pan option.

Saul,

Sounds like fun stuff. There are a handful of ways to do it that I can think of, but I'm sure others have handfulls of other idea's. What size of plane does it need to fly on? Thats a big first factor. The most motion you can get in a standard off the shelf servo is with any retract servo. These typically operate at 180 degrees. You can throw out all but the Airtronics 94739 though. It's the only one with proportional motion in that whole 180 degree range. The rest of them are full one way or the other. It's an expensive servo though.
Check out these links for options that are more do it yourself type projects.

Good luck.

Give this site a try too: http://www.robotstore.com/
Get the catalog, it's worth it. They have links to some good stuff that you might be able to use in this project.

You might want to take a look at ServoCity.com. They have what I think is just what you need.

how about using a 3d glass system and have your head to move the camera around while keeping your hands on the sticks? just use the 3d glasses that wil be cool

Just in case anyone's interested, I have a NIB Airtronics 94739 servo I'll never use. I bought it for a project I never finished. I'll let it go for $50 shipped.
