I use a Turnigy 9x radio for additional channels to control this pan and tilt camera (
http://www.hobbyking.com/hobbyking/s...5FNTSC%5F.html) from HobbyKing with the FatShark 5.8Ghz goggles. The pan and tilt is controlled by the HOV Pitch and HOV Throttle controls on channels 7 and 8 (until I can get the headtracker module I purchased synchronized). The view in the goggles is amazing as you actually control the tank from the tank.
