RE: Skywalker FPV
Some of the equipment I tested while I was building my Skywalker included the 800mW 900MHz video system and a few different cameras.
The 15" HEC TV makes a nice transportable display that will run on a 3s 5AH pack for about an hour. My Skywalker FPV plane also uses a 3s 5AH pack for the motor and R/C system. The video camera and transmitter run on their own 3s 1300mAh pack.
I bought the [link=http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=11442]Fiberglass Pan-Tilt Camera Mount[/link] from Hobby King for only $4 to support the camera that came with the video system. You add your own micro servos and it assembles very quickly with medium CA. By adding a head tracker device to your hat or goggles, the camera will tilt and pan to match your head movements as if you were in the cockpit. One of the reasons I decided to use my older Futaba 9C radio system for FPV was that the head tracker products can plug right into the trainer jack on the transmitter. Another reason was that the lower 72MHz frequency provides longer control range when flying beyond line-of-sight.
The camera that is included with the HK video systems is a Sony CCD 510x492 color pixel camera. It offers an affordable and acceptable start to your FPV adventures.
As an upgrade, I bought the FlyCamOne HD camera which has a 1240x720 color pixel display. It can also record video on-board while streaming video back to your FPV base. Now I have the added flexibility to always record my flights even when I am not flying FPV.
