I use the tilt/sensor setting on my Android Cell Phone.
I start the EC135 manuel and accelerate. At ca. +60kt engage HDG and ALT (Autopilot is engaged). Now the Instructions say that I can now lay the Cell Phone flat on the Table and the Helicopter will maintain the Altitude and Direction of flight. For me the Helicopter lowers and goes into a nosedive.
What am I doing wrong?
Request for Information.
