Eric builds a camera and video transmitter into an RC plane.
The HS-55's fit very well into a corner of the cavities for the elevator and rudder servos.
I CA'ed in a support for the sleeve of the rudder control to give it extra rigidity.
The antenna comes out the "anus" of the plane :-)
The completed plane. Next I need to test it. I found that even with a 2100 battery, the center of gravity was well back of where it should be. This is good, as I will be adding quite a bit of weight to the front of the plane.
I also constructed a mechanism to hang the plane from my office wall.
Kenny can hold the plane as well. Not a good long term solution, though :-)
Next, I turn to the camera pan and tilt mount. I decided to machine a piece of plastic in which the camera would mount. Here is the first proto type.
I used a old disk enclosure for the plastic because it was about the right thickness, and had a 90 degree bend in it already. My Dremel tool investment has paid off :-)
Here's my third attempt at the plastic part of the mount. The first two were meant to mount on the side of the servo. Here I decided to mount it to the bottom.
Most of the tooling of the plastic piece was done with an exacto knife. Very tedious.
Here's the complete mount. I used an HS-5245MG digital servo for the pan. This servo can be programmed to move through 180 degrees or more of motion and seems to be fairly tough.
I used an HS-56HB for the tilt. It does not have to support as much weight nor does it have to move as much as the pan servo.
Pan and tilt servo
The metal bracket connecting the pan servo to the tilt I got from Lynxmotion. I cut off the part I did not need. Hopefully this mount will be sturdy enough. It weighs in at 68 grams.
Here I load up the Easystar with all the components with which I expect to fly. With battery, it weights 760 grams. Note that I intend to mount the camera pretty far forward. All seems to balance well.
Head mounted Gyro.
Here I have installed the camera at the nose of the plane. I wanted a good field of view without the nose present all the time. I may stick a carbon fiber rod in front of the camera to give me a visual reference as well as a potential indicator of speed. Perhaps I'll even mount a small gun sight on the tip :-)
I purchase a tripod on which the antennas and receiver are mounted. Fixed to the tripod are two smaller ball and socket tripods called UltraPod II's. This way the antennas can be pointed in the right direction, and I don't have to extend the coaxial cables.
