I will gladly tell you anything you want to know. I'll start with the basic technical specifications:

Range: 1/4 mile with very good video. The system operates out to about twice this range, but with reduced video quality (snow, drop-outs, etc).

Hicam uses the same CCD camera that I use, so the specs will be the same.

All up weight of aerial portion: 2.0 ounces, which includes camera, transmitter, and antenna.

Transmitter power requirements: 5 to 11 volts. The RF power output is the same (100mw) regardless of whether you run the system at 5 volts or 11 volts, due to the design of the voltage conversion circuitry. I run a system on 2 lithium-polymer cells (which are gaining popularity among electric flyers) which gives excellent run time with very light batteries.

If there any other questions, please let me know!

Regards,
Bill
