JettPilot,
The dome is kind of small, so a conventional servo-on-a-servo PT system is hard to engineer to fit. I have given some thought to it though, and would appreciate any input. I have thought of putting the whole camera on a swivel, leaving the tilt to fit only one servo in/on the enclosure which is feasible. Finding/building a ball raced "Lazy-Susan" kind of swivel in a 2" diameter is the challenge.
These dome cameras are pretty high quality at 480 line and have good light transition qualities. Easy to install and good protection for the camera.
As far as the battery times, I guessed on them as I have been working on the setup for over 2 weeks with on-off-on usage with one battery which just ran down this weekend. A more considerate estimate would fall closer to your numbers.
What is the cost of your 1W unit w/ receiver? Which GPS/OSD did you settle on? I have looked at the SkySpy Telemetry board:

and the PicoPilot system:

For all the possibilities a FPV could encompass, the PicoPilot, with its autonimous navigation capabilities via it's computer configurable GPS waypoint routine, w/ altitude and throttle hold and such, covers just about all the bases. A 900mhz wireless modem is also available under Accessories for real-time telemetry/commanding. PicoPilot-NAT being $900.00 for the package, is a bit high, but delivers.
BoosterVision.com has a 2W unit as well as a 1W unit available. The 1W I ended up getting for a friend cost $169.00 + shipping. I ordered a 600mw unit, but they ran out of stock and sent a 1W for the same price, pretty good service IMHO.
Look forward to hearing your thoughts,
Cubby
