So just wanted to share my experience with this config. I'm a new flyer, having upgraded to 1.6.8 out of the box, only managed to get 100m range on the DJI Go app before it returned to home. This is in a huge open park, not ideal but I'm in the city so it's the best I can do. So I do all my reading and research and try some new configurations. As others have found using 1.5.7 with the new version of the DJI go app (3.0.0) causes the telemetry and video operation to lag - basically unusable. So I thought I'd try using Litchi as my primary flight management app - together with 1.5.7 and the FCC mod (I'm in a CE country). Well just got back from from taking it down to one of the local high schools which have like 3 huge adjacent ovals. Unfortunately as soon as I took off I'm still getting low range before the video cuts out - but get this. So I'm flying and I'm about 350 meters away - video is breaking up. Controller disconnects, loss of signal - but no return to home! The app became unresponsive and I could just make out the flashing green lights in the distance. So I'm trying for about 5 minutes to adjust the orientation but I'm freaking out at the same time and accidentally using the wrong stick going up in altitude! Finally I get the orientation right and fly back to where I'm standing - all of this flying manually. Then while I've got the bird on the ground footsteps and a figure emerge out of the dark. Turns out while I was trying to reorient and bring it back home, I was just over the edge of the oval hovering over this guys house! so he understandably pissed at this point. I apologised and told him what happened and he was OK with it. So lesson learnt - I'm reverting back to stock and just gonna leave it until my windsurfer antenna arrives. Was my bad as well flying just on sunset got dark quick and I lost track of time..will just have to wait till the weekend so I can get out of the city! I'll still look at Litchi for waypoints but won't use it as FPV again - will stick with the stock DJI app for that. Just glad I got it back in one piece!
