8. Model type specic settings
8.1 Heli mode
Selecting Heli mode activates the governor func-
tion.
When a change in load occurs in ight (e.g. caused
by a change in the collective pitch setting) the ROXXY
Smart Control automatically maintains a constant rotor
speed as dened by the throttle channel.
You can enter your preference for the rate at which
the speed controller carries out this adjustment at the
“Governor response speed” parameter of MULTIPLEX
Launcher; any of ve stages can be selected. The
default setting is a value which is suitable for the
majority of helicopters.
Governor Stabilize mode
The Governor Stabilize function creates a xed link
between the rotor speed and the throttle position. The
result is that rotor speed remains constant even when
battery voltage declines. In the default set-up Governor
Stabilize mode is disabled.
When you set the Governor Stabilize option to “Learn”
using MULTIPLEX Launcher, the learning process can
commence.
It is advisable to congure the residual battery capaci-
ty and the low-voltage warning at the same time, since
in this mode of operation it is not possible to detect
that the power of the ight battery is declining.
You should also activate telemetry output of rotor
speed, as it informs you of the status of the calibration
process.
Please note!: If you activate the Governor Stabilize
function, you must carry out a new Governor
Stabilize calibration using the throttle stick after
each programming procedure.
Governor Stabilize calibration procedure:
· Prepare the helicopter ready for ight.
· Connect the ight battery.
If you use a range of batteries, the calibration must
always be carried out using the battery with the
lowest cell count.
· Open the throttle until the desired rotor speed is
reached; note that the servo travel for THROTTLE
should not exceed about 75% at the transmitter,
to ensure that reserve power is available for speed
adjustment.
· As soon as the controller detects a rotor speed
which remains constant for two to three seconds, it
generates a warning message at the RPM display
address to conrm that the speed has been adopted.
· Now move the stick to the THROTTLE off position
and leave it there for three seconds (landing): the
value is now stored.
· Disconnect the ight battery from the speed control-
ler. Re-connect the battery.
Governor Stabilize mode is now selected, active,
and ready for use.
