Troubleshooting Guide
Problem Possible Cause Solution
Helicopter will not bind
to the transmitter (during
binding)
Low fl ight battery or transmitter battery
voltage Fully charge or replace the fl ight battery and/or trans-
mitter batteries
AR7210BX is not in bind mode
Make sure the bind plug is connected to the AR7210BX
BND/DAT port
Transmitter is not in bind mode
Power on the transmitter while holding the Trainer/
Bind switch. Hold the Trainer/Bind switch until binding
is complete
Transmitter too close to the helicopter during
binding process
Power off the transmitter. Move the transmitter to a
larger distance from the helicopter.
Disconnect and reconnect the fl ight battery to the heli-
copter and follow binding instructions
Helicopter will not link
to the transmitter (after
binding)
Helicopter is bound to a different model
memory (ModelMatch
™
radios only)
Disconnect the fl ight battery. Select the correct model
memory on the transmitter.
Reconnect the fl ight battery
Flight battery/Transmitter battery charge is
too low
Replace or recharge batteries
AR7210BX will not initialize
The transmitter is powered off Power on the transmitter
Controls are not centered
Center elevator, aileron and rudder controls. Make sure
the throttle is at idle
Helicopter moved during initialization
Make sure the helicopter does not move during initial-
ization. If necessary, shield the model from the wind until
it initializes
Helicopter will not respond
to the throttle but responds
to other controls
Throttle not at idle and/or throttle trim is too
high Lower the throttle stick and lower the throttle trim
The transmitter is not in normal mode or
throttle hold is on Make sure the transmitter is in normal mode and throttle
hold is off
The motor is not connected to the ESC or the
motor wires are damaged Connect the motor wires to the ESC and check motor
wires for damage
Flight battery charge is too low Replace or recharge fl ight battery
Throttle channel is reversed Reverse the throttle channel on the transmitter
Helicopter power is lacking
Flight battery has low voltage Fully charge the fl ight battery
Flight battery is old or damaged Replace the fl ight battery
Flight battery cells are unbalanced
Fully charge the fl ight battery, allowing the charger time
to balance the cells
Excessive current is being drawn through
the BEC
Check all servos and the helicopter motor for damage
Tail drive belt tension is not correct See "Checking Tail Drive Belt Tension" in this manual
Post-Flight Inspections and Maintenance
Ball Links
Make sure the plastic ball link holds the control ball, but is not tight (binding) on the ball. When a link is
too loose on the ball, it can separate from the ball during fl ight and cause a crash. Replace worn ball links
before they fail.
Cleaning
Make sure the battery is not connected before cleaning. Remove dust and debris with a soft brush or a dry
lint free cloth.
Bearings Replace bearings when they become notchy (sticky in places when turning) or draggy.
Wiring Make sure wiring does not block moving parts. Replace damaged wiring and loose connectors.
Fasteners
Make sure there are no loose screws, other fasteners or connectors. Do not over tighten metal screws in
plastic parts. Tighten screw so parts are mated together, then turn screw only 1/8th of a turn more.
Rotors
Make sure there is no damage to rotor blades and other parts which move at high speed. Damage to these
parts includes cracks, burrs, chips or scratches. Replace damaged parts before fl ying.
Gyro
Make sure the AR7210BX is securely attached to the frame. Replace the double-sided tape when necessary.
The helicopter will crash if the AR7210BX separates from the helicopter frame.
