Blade 300 CFX 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 transmitter batteries

AR7200BX is not in bind mode Make sure the bind plug is connected to the AR7200BX BND/DAT port

Transmitter is not in bind mode Refer to your transmitter's instruction manual for binding instructions

Transmitter too close to the helicopter during the

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 helicopter 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

AR7200BX will not initialize

The helicopter was moved during initialization Lay the helicopter on its side during initialization if windy

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 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 throttle trim to the lowest settings

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 Power down helicopter. 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

Helicopter will not lift off

Main rotor head is not spinning in the correct direc-

tion

Make sure the main rotor head is spinning clockwise. Refer to motor control

test

Transmitter settings are not correct Check throttle and pitch curve settings

Flight battery has low voltage Fully charge the ﬂ ight battery

Main rotor blades are installed backwards Install the main rotor blades with the thicker side as the leading edge

The helicopter tail spins out

of control

Rudder control and/or sensor direction reversed

Make sure the rudder control and the rudder sensor are operating in the

correct direction

ﬂ ight

Cyclic gain is too high Decrease Dial 1 on the AR7200BX

Headspeed is too low

Increase the helicopter's head speed via your transmitter settings and/or

using a freshly charged ﬂ ight pack

Dampers are worn Replace the main rotor head dampers

Observed Behavior Suggested Adjustment

Cyclic response is too slow or too fast

Adjust dual rates to ﬁ t your ﬂ ying style. Refer to your transmitter instruction manual for

more information

Adjust the control behavior parameter in the AR7200BX to ﬁ t your ﬂ ying style

Control inputs feel delayed Increase Dial 2 on the AR7200BX

The helicopter seems to overshoot control input and then return Decrease Dial 2 on the AR7200BX

The helicopter tail stops too abruptly Decrease Dial 3 on the AR7200BX

The helicopter tail does not stop precisely

Increase Dial 3 on the AR7200BX

Increase the rudder gain in your transmitter

Adjust the rudder heading lock gain parameter in the AR7200BX

Make sure the tail drive belt tension is adjusted correctly
