disarm command

[FR MD PHB]

Hello,
I couldn't find an answer on the forum.
maybe you know where is the solution?
my H520 no longer arms.
in "take off" "angle" mode I drag the arrow and I get the alert (see yellow rectangle)
up-to-date software.
waiting time (20 mins) done just in case .... but the drone flew in January
at first it happened a few times but now it's permanent.
Thank you for your advice.

Hi, i guess you have to calibrate the sticks, because one of them is not in center. I had this problem as well , weeks agou.

You are suffering from the fine oxidation that affects the sticks on the ST16S. You will need a plastic safe electrical contact cleaner. Then follow the information in this thread at post #9 Typhoon H+ takes off When starting rotors. The controller for the H Plus and the H520 are physically the same. Make sure to read the PDF attached to that post also. This should cure your problem.

hello,
I took a little time to answer but the weather conditions in the north of France did not allow flying.
Thank you for your advice because indeed the J3 of the calibration of the sticks remained at red.
So dismantling the back shell of the ST16, spraying it in the right place and everything is back to normal.
Well almost because the camera tilts but does not go up.
Probably a final adjustment problem.
I'll look at it tomorrow.
