ok guys i have the drone in my hands
when i started the drone up it made a ringtone till i connected it to the laptop with the yuneec GUI.
in the GUI it gave like the picture
When i start enable testing
And i click on the green 1 all 3 turn but not the One that should turn. After 2 Presses it stops and i need to turn on and off the drone again.
After i try to ESC assignment when turning moter 1 that after a couple of Turns it Gives me a error, and i need to turn the drone off and back in again.
"Edit" he told me last time he flew the drone he almost hit something and while trying to react het landed it a bit hard from like 2 meters no crash but a hard landing.
not sure if this helps
after a few more tests "connecting the drone to the GUI and Enable testing pushing the 1 green moter like in the picture"
sometimes when i power on the drone the 2 back "landing lights" are red, and the front is white.
The moter that turns green in the GUI moter 1 that connected landing light does not always turn on, when it does 2 little blue light on the ESC light up and it tryes to power the moter in the test but quits fast.
When the white light is not on only a 1 little blue light on the ESC all 3 moters will spin when pushing the green moter 1 except moter 1 wont move not even try.
