Blade Helicopter Belt Tension; Troubleshooting Guide - BNF BLADE 450 X Instruction Manual

AR7200BX Parameter Menu Tips
Refer to the Spektrum AR7200BX manual to fine tune the Blade 450 X to your
flying and control style via the AR7200BX parameter menu.
If you would like to change the control behavior of the flybarless system to a
pre-defined behavior in the AR7200BX, adjust parameter B (default behavior is
transmitter).
AR7200BX Fine-tuning and Adjustment
Observed Behavior
Cyclic response is too slow or too fast
Control inputs feel delayed
The helicopter seems to overshoot control input and
then return
The helicopter tail stops too abruptly
The helicopter tail does not stop precisely
Blade 450 X Troubleshooting Guide
Problem
Helicopter will not bind to the trans-
mitter (during binding)
Helicopter will not link to the trans-
mitter (after binding)
AR7200BX will not initialize
Helicopter will not respond to
the throttle but responds to other
controls
Helicopter power is lacking
Helicopter will not lift off
Adjust end points to fit your flying style. Refer to your transmitter instruction manual for
more information
Adjust the control behavior parameter in the AR7200BX to fit your flying style.
Increase Dial 2 on the AR7200BX
Decrease Dial 2 on the AR7200BX
Decrease Dial 3 on the AR7200BX
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
Possible Cause
Low flight battery or transmitter battery voltage
AR7200BX is not in bind mode
Transmitter is not in bind mode
Transmitter too close to the helicopter during binding pro-
cess
Helicopter is bound to a different model memory
(ModelMatch radios only)
Flight battery/Transmitter battery charge is too low
The helicopter was moved during initialization
The transmitter is powered off
Controls are not centered
Throttle not at idle and/or throttle trim is too high
The transmitter is not in normal mode or throttle hold is on
The motor is not connected to the ESC or the motor wires
are damaged
Flight battery charge is too low
Throttle channel is reversed
Flight battery has low voltage
Flight battery is old or damaged
Flight battery cells are unbalanced
Excessive current is being drawn through the BEC
Tail drive belt tension is not correct.
Main rotor head is not spinning in the correct direction
Transmitter settings are not correct
Flight battery has low voltage
Main rotor blades are installed backwards
If you would like to have the cyclic behavior to feel more linear OR more like
a flybarred helicopter, increase the cyclic response by adjusting parameter G
(default is 'slightly increased').
Refer to the Spektrum AR7200BX manual for specific details on each
parameter.
Suggested Adjustment
Fully charge or replace the flight battery and/or transmitter batteries
Make sure the bind plug is connected to the AR7200BX BND/DAT port
Refer to your transmitter's instruction manual for binding instructions
Power off the transmitter. Move the transmitter to a larger distance from the
helicopter. Disconnect and reconnect the flight battery to the helicopter and
follow binding instructions.
Disconnect the flight battery. Select the correct model memory on the trans-
mitter. Reconnect the flight battery
Replace or recharge batteries
Lay the helicopter on its side during initialization if windy
Power on the transmitter
Center elevator, aileron and rudder controls. Make sure the throttle is at idle
Lower the throttle stick and lower the throttle trim
Make sure the transmitter is in normal mode and throttle hold is off
Connect the motor wires to the ESC and check motor wires for damage
Replace or recharge flight battery
Reverse the throttle channel on the transmitter
Fully charge the flight battery
Replace the flight battery
Fully charge the flight battery, allowing the charger time to balance the cells
Check all servos and the helicopter motor for damage
See "Checking Tail Drive Belt Tension" in this manual
Make sure the main rotor head is spinning clockwise. Refer to the motor
control test
Check throttle and pitch curve settings and pitch control direction
Fully charge the flight battery
Install the main rotor blades with the thicker side as the leading edge
