Thanks for the comments. Yeah, I threw that Interpolate video in to show Litchi misbehaving. To keep the video "short", its already almost 15 minutes, I left out a LOT. I flew many times with Litchi with some simple loops, one point POI etc. The gimbal was all over the place straight up to straight down, and Litchi wouldn't let me get control from the RC gimbal roller. Another time it stayed out of focus the whole time. I really tried not to trash Litchi because their online mission feature is amazing and fantastic, and they have a good history with Phantoms. I just think they rushed this one out the door while clearly beta. There are other youtube reviews on Litchi with Mavic that show similar behaviour. I'm sure it will get fixed.
Its unfortunate that Autopilot is iOS only, their loss really, and DJI GSPro is hard enough to adjust its tiny settings on an ipad, a phone would be impossible. However, I have a mini4 and they both run well. I have also had software crashes or lock-ups occasionally but no problems rebooting without issue. Never in a mission though.
Really all are good value given the price. Patience and learning from simple challenges before expecting too much is the way to go with all of them.
