Problem for quad X

Hello again, dear friends
I posted log files above…
Also my battery is Li Po ,4cell,25c,4000mah and brand “ace”…
And according to what you have said , I changed the settings of the "Flight Modes"and "Fail safe"
I’ve posted pictures of both below…

Thank you very much , For help…

No expert here with logs, and I just took a quick look, but is your GPS; HDOP or sat count, showing anything in the Ground Station? I see nothing in log for that data. Also on my APM board the GPS is attached to the side port, not the top one, but you are using a MN8 and I am not. Not even sure if APM uses MN8 GPS.

Did you try loading Rover then Copter and re-doing the set-up as I mentioned above?

If not, do that, and send a log after a brief flight.

Hi, my dear friend , Good time…
Left and Right Problem Quad" X "And the front and rear solved…
In my opinion, this was done by Uncheck the “Simple” and “Super Simple” flight modes in all modes…
But because I saw it was right , Me again not loading Rover then Copter and re-doing the set-up as you mentioned above !
But today I had a short flight and posted logs below…
I think also the reason for the GPS problem , It was because the previous flight was closed area and the GPS Antenna did not…
But the today flight , was open area…

Glad to help. Lot of things to learn. I like your DYI on radio and quad. Did you build all the boards or just strip from parts that you found?

If you are only monitoring Voltage on FS use 3.5 per cell as safety value. If you have Current as well, then 80% of battery capacity.

Your post got my AMP Quad in the air for a few days, so that was fun. It has been over a year since I last flew that Quad.

I have found that setting flight modes to:
Stabilize
Alt Hold
Loiter
A good way to test things on a new build.

Then do an “auto” Tune on either on a Channel option or as a flight mod choice, not sure what you Radio Transmitter allows.

PS; I think there is a way to mark the subject as “Solved” so I would do that- but not sure how- it may help others.

PPS: I am fro Buffalo Wyoming USA and you are from where?
