Has anybody running a slave controller for the camera used something like this? http://www.newegg.com/Product/Product.aspx?Item=9SIA1GK2CS2999&ignorebbr=1 At $129 (plus $20 for a battery and charger) it would seem to be a pretty good way to go? no lag due to direct HDMI output? Lot cheaper than an ipad or shield. Could possibly even pair with the hobbyking FPV kit to get a HD FPV setup for less than $200. Any thoughts?
