HI! I am new to the 3DR solo and I haven’t really been able to get it to work… i have the gimbal and for some reason the app and the go pro aren’t really connecting. Before i put the gimbal on the HDMI cord wouldn’t show the footage off the app with either of my HERO 4 blacks. I also tried a HERO 3 which worked temporarily.. now that i have the gimbal i am able to control the go pro (start and stop it) but i can’t see the live video and am pretty much flying by line of sight. I have tried re-connecting the HDMI inside the drone and turning everything off multiple times. What else can i do??
