James - I used one of these [link=http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=34063&item=3188533 231&rd=1]wireless cameras[/link] that I bought from ebay. It works well using a 9v battery or if you feed it with the heli's pack. Problems I encountered: if you use the heli's power source and you have a brushed motor you'll always have interferance...not the case with a brushless motor. The picture quaility isn't to Hollywood standards, but it's pretty nice for the money. It is a bit slow reacting to light changes though.
