control. If the heli is tilted to one side, Spektrum AR7210BX permanently steers the swashplate opposed
to the inclination. In the region around horizontal position the swashplate will always stay nearly
horizontal to the ground. The system constantly tries to bring the helicopter back to the horizontal
position as long as the helicopter is oblique.
When SAFE technology is deactivated on the other hand, the swashplate will always be moved back

to neutral position (perpendicular to main rotor shaft) as soon as the helicopter is standing still for a
few seconds, independant of the current leveling. Here the system only corrects currently occurring
rotational movements, but does not regulate the absolute deviation from horizontal position.

movement also the collective pitch is moved in positive or negative direction when SAFE
technology is activated and the helicopter approaches the horizontal position. The pilot can
add collective pitch in the same direction by using the throttle stick, but not in the opposite
direction. Check to see if this works correctly and whether the control directions are correct.
If the helicopter is kept in hovering position, some positive collective pitch must be applied
by SAFE technology and you can use the throttle stick to add more positive pitch, but
