Hi! My H901S (X4 Pro) recently started giving the message "Need reset compass" after I have succeeded calibrating it. Since then it is impossible to controll it, it drifts and yawns and so on. Please! Has anyone an idea what I should do, or how to "reset compass"?
Thanks for all suggestions! Miss my flying.
