C Full Throttle Position
At Menu Point C, you have to set full throttle position of your ESC or throttle servo. Here
the output [THRO] can be only controlled by the throttle stick when the RPM
Governor type is set to "nitro." In "electric" mode the throttle output will stay locked to
your low throttle value. You can set the full throttle position without the motor running high.
Otherwise there is no difference between the modes "electric" and "nitro."
Move the throttle stick to full throttle. The Status-LED lights up Blue. This means that a new
valid throttle position has been detected. If the Status-LED lights up in Red, the distance
between the lowest throttle position and the full throttle position is too small. Since this will
have a negative effect on the control behavior of the system, this throttle position cannot be
used. In this case, check the setting of the transmitter and the programming of the ESC or
readjust throttle servo, carburetor position and throttle linkage rod. If necessary, set the lowest
throttle position at Menu Point B again.
Similar to Menu Point B the Status-LED is OFF when entering Menu Point C. As long as
you do not move the throttle stick, the currently stored position will not change. Press the button
to skip Menu Point C without changing the throttle position when performing subsequent
adjustments in Setup menu or Governor menu. You need to move the throttle stick at Menu Point
C at least once to change the current full throttle position.
Press the button to save the configuration and to proceed to Menu Point D.
D Adjusting throttle curves in the transmitter
Similar to Menu Point A, Menu Point D only serves to give you some status information. At
Menu Point D the different activation points of the RPM Governor will display based on color
and state of the Status-LED. You can prepare your transmitter for use with the RPM Governor
function. The information conveyed by the Status-LED is basically the same in every Governor
operation mode. However, the setup of the transmitter will be slightly different, depending on
whether the mode "electric" or "nitro" is used.
Electric
In "electric" mode, the ESC is no longer controlled by the pilot via the transmitter. The
Spektrum AR7210BX takes over full control of the ESC. With the transmitter you only specifiy
the desired rotor RPM you want the helicopter to maintain. When setting an RPM higher than
zero, the Spektrum AR7210BX will speed up the rotor smoothly and ensure that the rotor RPM
is kept constant throughout the flight. To practice autorotation landings, you can keep the
Spektrum AR7210BX in a special mode, which causes the ESC to be switched off during the
maneuver but speed up the rotor RPM faster when aborting the autorotation (faster than with
the initial soft start).
The rotor RPM is set via the transmitter's throttle channel. You may use the transmitter's
throttle curves for instance, so you can switch the motor on and off and simulate different
speeds using the flight mode system of the transmitter. Instead of curves, you only have to set
horizontal lines so that the rotor RPM value does not depend on the throttle stick position but
is fixed in each flight mode. The flight mode switch then acts as a switch that switches between
different speed settings.
