Had a couple of unsettling experiences last week. I have used Litchi very successfully with P3, P4, Mavic and P4P on many occasions. These two were quite different.
These were planned waypoint flights but Instead of going to altitude and then moving to the first waypoint the drone hovered about 2.5 metres above the ground. Too high to grab so I managed to terminate Litchi and regain manual control - in a fashion. The controls went squirly - ie. Pushing forward on the right hand stick sent the drone up rather than forward, pushing back on the right stick brought it down enough so I could grab it. Holding the drone I pulled the left stick back to stop the motors and they immediately went to full speed. Finally managed to shut it down by holding down the RTH button at the same time.
I shut the drone down and fired up DJI GO and everything was fine. So I tried Litchi again and everything behaved flawlessly.
Next day the same thing happened - first Litchi flight went crazy, motors spinning at top speed, hovering etc. Emergency shutdown, DJI GO worked fine and then the remainder of the Litchi flights that day behaved themselves.
I cannot understand what could have happened although I note that there are issues with Litchi and the latest DJI firmware that I had just uploaded (although posts indicate the Waypoint mode is not affected).
Really the reason I am posting this is to say to anyone who is using Litchi, if your drone hovers within grabbing range rather than moving off correctly, grab it and hit RTH and pull back the left joystick - thats the only way I could stop the drone. Mind you I had a helper as 3 hands are required to do this!
