[size=14.6667px]Today's flight started well but when I turned it around to manually fly home the following happened.
[size=14.6667px]As I put in some down stick the Mavic went backward and then started rotating clockwise at about 1 revolution per second. Then started to climb to its' max altitude of 120 meters. Then I tried the right sticks (I'm mode 2) to see what they did. They did nothing. The only way to stop the spinning was to put in full left rudder but letting go just caused it to spin again.

[size=14.6667px]The only way to bring it back was to perform an automated RTH which it did respond to and then came home to about 1 meter high. When it got to this height the spinning stopped and it landed fine.

[size=14.6667px]Firmware is the latest and I'm running Litchi on my Galaxy S5

[size=14.6667px]Not tried another flight since until I get my head around what happened.

The siganl being reported on the flight back was deemed poor.

Did you recalibrate after the latest firmware install? If so, what did you calibrate?

Must be something with Litchi then, heard of more problems with it.

Try flying with DJI GO app and see if it repeats itself.

Hmmm. Seems like Litchi need to evolve their Mavic code quite a lot.

IMHO, at this early stage of it's development, everyone should probably consider Litchi's Mavic support only at beta, and fly accordingly.
