I would not use the FC40 camera wifi or any other GoPro type camera with wifi on a 2.4 ghz system.There are a lot of posts from people that have had control issues or worse..fly aways! I had a 1.2 ghz transmitter that put out 1500 mw. The video was great ,but it put me into fail safe at 100 m . I changed to a 600 mw 2.4ghz fpv transmitter .
