  There were a couple of posts with a similar thread, I think that my comments
will apply to all of these...

  I have been looking into this for a short time now.  Here are my thoughts
and findings to date:

 I have the required FCC license to use a video transmitter for this type
of operation.  For those of you who are interested, you will need an Amateur
Radio license of at least a "Technician" grade or higher.  Note that it is
NOW VERY EASY to get this license.  There is no longer a need to learn Morse
Code. You only need to pass (70%) a 55 question multiple choice exam.  This
is the SAME license that will allow you to use the 50 MHz R/C channels
(channels 00 through 09) in addition to a lot of other stuff.

  I decided that to properly do airborne video without a monster plane I
would need a small, light camera, and a small and light transmitter.  It
would be nice if this equipment didn't draw a lot of current so that I would
not need a heavy battery to supply the operating voltage.

 In my search I found the following items:

  Camera:
      Black and white, 240 lines
      1.4 x 1.3 x 2.25 inches
      2.5 ounces
      7 to 14 Vdc at 80 mA.
      $289.00

  Transmiter:
    Mini board:
        1.0 x 1.3 inches
        weight unspecifed, but it must be lite!
        output 80 mw on 434 MHz
        7 to 10 Vdc at less than 100 mA.
        $129

         This unit is great (small, etc) but limited to
         only ONE frequency (434 MHz).

    Small board:
        2.25 x 4 inches
        2 ounces
        output, adustable from 80 mw to 1.5 watts.
        13.8 Vdc, 350 mA at 1 watt, 200 mA at 100 mw.
        Crystals can be changed for different frequencies on the 434 MHz band
        $129

 All of these can be purchases from:
 
   P. C. Electronics
   2522 Paxson Lane
   Arcadia CA 91007
   USA
   (818) 447-4565

 They also have the converters to allow you to view this on a normal
Television receiver

  Note: They will not sell a transmitter to you unless you have a valid
Amatuer radio license (their policy, not mine).  I have no connection to
this company and am just forwarding this info for interested parties.
I do own some of their other ATV (Amateur radio TeleVision) equipment, and
it works fine.

 Note: You will need to be very careful to sheild your R/C reciever and
servo system to be sure that you do not get any interference from any on
board transmitter!!!

 I am very close to purchasing one of their transmitters and cameras.  I
just can't decide on the micro transmitter (just one frequency and 80 mw
of power) or the larger, more flexible transmitter.

 I hope this information helps.
