GOPRO Camera Operator?

I want to put a pan tilt on my tricopter in the future and have my dad control it from another TX. i wanna make some cool video by doing this. now how would i go about doing this? would i have to buy another Tx and Rx and put it on? or is there a cheaper easier way to do this? thanks for the help

You can build one yourself!

Innovative thinking a little fantasy could bring you to a reasonable good result that could work.
