Important:
no exceptions are allowed regarding the setup of Horizon and Rescue modes, in particular:
•
The coll.pitch travel must reach its 100% marks as displayed in the DIAGNOSE menu, positive and negative, with correct signal
direction.
•
For using the horizon modes ‘Acro’ and ‘Upright’ and the corresponding rescue modes, the main blades’ angle of attack must be
set to exactly 0° when connected to the DIAGNOSE/TRIM menu, otherwise the proper function of the system’s horizon and rescue
features cannot be ensured.
Self-leveling can be used for various purposes: primarily as a training aid (“safety net”) for beginners, but is also useful for advanced
pilots. Self-leveling remains useful from the initial learning phase right up to practicing to master complex maneuvers. Self-leveling
stabilization may be used wither purely as a „rescue switch“ in an emergency, or in a permanently activated (“Coax mode”) state.
Self-leveling can act as an invaluable support during aerial photography flights, for example, particularly at greater distances, as an
in-real-life orientation-training tool, or in deed in many other ways.
HOW TO ACTIVATE THE HORIZON STABILIZATION
First optimize the head gain setting. We suggest using a pot or slider on the transmitter for instant adjustment access in tuning.
This should only be done with deactivated Horizon modes, as these would interact in such that a perfect head tuning would not be
possible.
Now choose the desired option from the HORIZON/RESCUE menu. Afterwards you can tune the gain (assistance) and engage the
desired mode of the Horizon stabilization via the Horizon channel in flight.
It is recommended to use a switch for the Horizon channel, to activate and switch between modes.
Note: in ‘Acro’ and ‘Upright’ mode the mode (Horizon or Rescue) depends on the signal’s polarity (direction) on the Horizon channel
(see next page for more details).
FLYING WITH HORIZONTAL STABILIZATION
Begin with a low stabilization gain and increase carefully. Too high a gain may increase the tendency to oscillate. A very hard set up
head stabilization can also increase the tendency to oscillate in Horizon modes.
Usually lift-off and landing is possible with activated self-leveling. This should be tested first at a gain not higher than 30%, and defini
-
tely not in Rescue mode. The tendency to oscillations may also be increased before lift-off, if standing on a hard surface, and during
high speed flight.
IMPORTANT
W
hen flying with permanently engaged self-leveling, do not reduce servo travels for aileron and elevator at the transmitter too much
(no exessively low Dual Rate setting), otherwise, the priority of the manual control (override) may get lost.
The Horizon stabilization can also make pirouettes out-of-round, since it wants to bring the main rotor disc into its neutral hover
attitude.
