That has been done before and probably by several people. We had one situation where the plane had the camera and the person on the ground had a virtuality reality helmet on and flew the plane as though he was in the cockpit. It was pretty cool, to say the least. He took off with it, flew it around, and then landed it, all the time with the helmet on and facing backwards to the flying field. We captured the video in real time to a VCR recorder (this was about 8 years ago, by the way). It was pretty slick.

Ok, what you have to do is try your current setup for distances. See what it will really do as far as range is concerned. The system you currently have may not be able to do the range no matter what you do (short of replacing the transmitter downlink with one with more power). I've seen them for sale at aound $200 on - line, so somehow, I don't think your $40 setup will do as you hope it will do.

For the first trial flight, the owner had the system setup so a servo, attached to an auxiliary channel, turned the camera on after airborne, then another servo attached to another auxiliary channel to turn on the transmitter. That downlinked the video signal to a receiver on the ground that was hooked up to a VCR. The VR helmet was connected to a separate port on the VCR, as I recall it. That way both the VR helmet and the VCR got the downlink.

One thing you will really have to watch out for is if the transmitter inteferes with your receiver on board the aircraft. And, not to mention the weight of the whole on-board setup to make sure you have enough power to do what you want to do.

There is a whole forum here on RCU that has all sorts of information on this, with how-to's, where to get equipment, what they have encountered as far as problems are concerned, all sorts of information. I suggest you go there and do some reading to see what's going on with this. It's not that simple a task.
