I have a p2 with H3 3D gimbal, Hero 3 black cam, isod mini, 2.4ghz datalink and a black pearl FPV screen. Things go well in flight all systems work well and vision to screen with all data is fine. My problem is that prior to installing isod and datalink i was using go pro app for video feed. This worked well and i was able to choose when and how i started recording video or taking photos. With the upgrades added i don't know how to get control over camera? What i end up doing is starting the cam recording prior to take off so it is recording constantly. This ends up making editing etc much more wasteful and creates massive video files. Can anyone tell me what i need to do to get remote control of the gopro functions with the system described or info on what's required to get the function?
