Hi All, I know this has been reported but I havent seen it for awhile not sure whats happening with the  error. I sent an email to both DJI and Litchi

Phantom 4 Pro , Using Litchi  3.10.3 , RTH altitude set @ 98 feet, All firmware and software up to date.

  

  

I had a problem with RTH on at least two occasions. On 2-11-2017 I was at 126’ and pressed the return home button and the aircraft ascended to 751 before I cancelled the RTH. ( I was talking to someone and not paying attention to what the drone was doing) and before that on 2-10-17 I was at 92 feet and used the RTH button and the drone flew to 219 feet before I cancelled the RTH .

This was corrected in Firmware version 1.4.10
Confirm that is what your Phantom is running.

Thanks for the reply,  
Looks like the Phantom 4 Pro is running under  firmware V01.02.0304 (CURRENT according to DJI Assistant), the controller in 01.03.00.00 and the DJI app version is 4.0.2, the Lichti App is 3.10.3

Where do I get the 1.4.10 ? I looked on the DJI website.


Thanks
Dale

I thought latest ac fw was v01.02.0304???

Sorry ... I was looking at an old screenshot from a P3.
You are right, the correct firmware for the P4 pro is 1.02.0304.
Users that did have the rising RTH issue reported that was fixed with the new firmware.
Test it with the Go 4 app and see if that behaves any differently.

UPDATE: I used the RTH button a few times today without any problems (Litchi) so I will have to do a little experimenting to find out what causes the problem.

Just thinking out loud, what could cause it to keep climbing ? perhaps it was seeing an obstruction, real or imagined by the collision avoidance sensors and was trying to climb to get above it. Did you have collision avoidance on at the time the RTH was triggered?
