Below is a project I will soon begin.
In the picture you can see the transmitter, color camera, battery and a switch plug.
Just to give you an idea of size comparison I've placed an American Cent in the picture :-)

Below is a picture to simulate a snapshot with the camera placed on the side of the rocket.

I've placed the transmitter and the camera in a battery casing. I'll use this configuration and place it under my ECO 8 flying helicopter. It should be interesting to see how the videos turn out.
