5. SETTINGS

5.1. Servo Reverse

If the servo directions are correct, the
swashplate will tilt only to the front of the
helicopter, when you hold your hand behind
the 2 rear sensors or cover them with 2 fin-
gers (Pic.2.).
If you cover the front 2 sensors, the
swashpalte must tilt only to the tail of the
helicopter. Covering the 2 left sensors or
holding your warm hand in front of them will
cause a tilt of the swashplate only to the
right (Pic.3.).
Pic.3
If you cover the right 2 sensors, the
swashplate will tilt only to the left. For all
(90° and 120°!!!) swashplates only nick- and
roll-corrections will occur, if the Stabilizer is
correctly set, no pitch-corrections. Gene-
rally, if you hold the helicopter in the air
above your head and tilt it, the swashplate
must always try to stay horizontally. Only in
