Yes that is a camera

Yes under the middle part of the body there is a wireless video camera.

I plug the receiver to my camcorder and record video. (that is why I need the stabilizing system)

It operates on 2.4 Ghz and is very low powered...the RC transmitter/receiver is ALSO 2.4 Ghz. So I put the camera at its lowest frequency (within the 2.4 spectrum) and the RC system gets out of the way. If the RC transmitter is between the video transmitter and receiver, then I get some noise or drop outs.

I don't have any demo's yet...I only recently installed it on this helicopter (I originally had it on another smaller helicopter).
