All flybarless gyro systems require uninterrupted power.
During even a short power interruption/brownout, the flybarless unit must reboot and reinitialize.
CAUTION: If a power interruption/brownout occurs during flight, a crash will occur.
It is your responsibility to ensure the Spektrum AR7210BX has sufficient power
without interruption.
Some of the power system components that affect the ability to properly deliver adequate
power include:
• The switch harness, battery leads, servo leads, regulators etc.
• Receiver battery pack (number of cells, capacity, cell type, state of charge)
• The ESC's BEC capability to deliver current to the receiver when load is placed on the
servos. This is the number one cause of power interruptions in electric helicopters.
The Spektrum AR7210BX has a minimum operational voltage of 3.5 volts. Test the power
system according to these guidelines:
Recommended Power System Test Guidelines
Perform the following test with a voltmeter. The Spektrum Flight Log or Telemetry Modules
(TM1000/TM1100) work well for this test.
Plug the Flight Log into an open channel port in the receiver and, with the system on, load
the servos by applying pressure to the swashplate with your hand for 3 minutes. Monitor
the voltage at the receiver. It is important to load the swashplate for 3 minutes. If a voltage
regulator becomes hot, it can lose its ability to supply current. An alternate method is to power
on the system and rapidly move the control sticks (stir the sticks) with no load on the servos
for 3 minutes. The voltage should remain above 4.8 volts in both cases.
