Spektrum BEAST X AR7210BX Mode D'emploi page 21

Combustion Drive System (Nitro/Gas)
Magentic sensor
located at clutch bell
Menu Point A verifies (1) the RPM sensor is functioning properly, (2) the RPM sensor wire
is connected correctly and (3) if there is a usable RPM signal. Caution: at this menu point
the throttle channel is unlocked. This means you have full control over the throttle output
[THRO] with your transmitter to control the speed controller or throttle servo.
Electric Model — For safety, remove the rotor blades from the model. Give some throttle so
that the motor starts to rotate and the phase sensor or the ESC outputs a RPM signal. Once the
motor starts, the Status-LED on the Spektrum AR7210BX lights up Red.
WARNING: Use extreme caution when performing the Governor Function Test.
Never touch the motor when it's running. Keep all hair, hands and dangling or
loose items away from rotating parts.
Nitro/Gas Powered Model — You can rotate the clutch or engine crankshaft by hand until
the signal generator (magnet or similar) passes the sensor. When the signal generator is within
the detection range of the sensor, the Status-LED lights up Blue.
If the Status-LED on the Spektrum AR7210BX does not light up as described:
• double check the wiring
• verify the sensor's power wires are of correct polarity
• if you have a magnetic sensor, verify the magnets are installed with the correct polarity
• using a crankshaft sensor, verify the sensor is mounted correctly
In addition to the sensor' s function control, check the throw setting for the throttle servo in the
transmitter and adjust using the following steps:
1. Set the throttle to mid-stick position and attach the servo horn, so that the throttle linkage is
at a 90° angle to the servo horn.
2. Adjust the linkage length according to your helicopter's instructions, so that it is positioned
perpendicular to the linkage lever at the carburetor.
3. Adjust the lever at the carburetor so that it is halfway open noting the markings on the carburetor.
4. Move the throttle stick to full throttle and adjust the servo travel in the transmitter
accordingly, so that the full throttle position is reached without binding.
