Flying The Blade 450 X - BNF BLADE 450 X Instruction Manual

Motor Control Test
Place the helicopter outdoors on a clean, flat and level surface (concrete or
asphalt) free of obstructions. Always stay clear of moving rotor blades.
1 The motor beeps twice when the helicopter's ESC arms properly. Before
you continue, confirm that TH HOLD is ON.
WARNING: The motor will spin when throttle is increased while TH
HOLD is OFF.
2. Check the swashplate directions to ensure they are moving in the correct
direction. Please refer to the diagrams above for reference.
Blade 450 X Pre-Flight Checklist
❏ Check all screws and ensure that they are tight
❏ Check belt tension and ensure that it is not too tight or too loose
❏ Check main and tail blades to ensure they are not damaged
❏ Check all links and make sure they move freely but do not pop off easily
❏ Check that flight battery and transmitter battery are fully charged
❏ Check all wires to ensure that they are not cut, pinched, or chaffed and
are properly secured
❏ Check all wire connections

Flying the Blade 450 X

• Always keep aircraft in sight and under control.
• Always turn on throttle hold at loss of control or rotor strike.
• Always use fullly charged batteries
• Always keep transmitter powered on while aircraft is powered.
• Always remove batteries before disassembly
• Always keep moving parts clean.
• Always keep parts dry.
Consult local laws and ordinances before choosing a location
to fly your aircraft.
Select a large, open area away from people and objects. Your first flights
should be outdoors in low-wind conditions. Always stay at least 30 feet
(10 meters) away from the helicopter when it is flying.
The Blade 450 X is not intended to be flown indoors where it might be
possible to fly a Blade SR or Blade CX2. Experienced pilots may find it possible
to fly the helicopter in a large gymnasium.
CAUTION: The Blade 450 X is intended for pilots with experience flying
aerobatic, collective pitch helicopters. The Blade 450 X is more respon-
sive than other Blade helicopters, such as the Blade SR. If you are not an
experienced 3D or collective pitch helicopter pilot, do not attempt to fly
this product.
Takeoff
Deliberately increase throttle and establish a hover at least 24" (0.6 meter)
high, outside of ground effect.
CAUTION: Do not give any aileron, elevator or rudder commands before
takeoff or the helicopter may crash during takeoff.
Flying
The helicopter lifts off the ground when the rotor head reaches a suitable
speed. Establish a low-level hover to verify proper operation of your helicopter.
You must not set any trim; the flybarless design of the Blade 450 X renders
trim unnecessary. Setting trim or sub-trim can cause an unwanted drift or rota-
tion of the helicopter.

WARNING: Stay at least 30 feet (10 meters) away from the helicopter
when the motor is running. Do not attempt to fly the helicopter at this
time.
3. Ensure the throttle is lowered completely. Confirm the transmitter is
still set to normal flight mode. Turn throttle hold off at this time. Slowly
increase the throttle until the blades begin to spin. The main blades spin
clockwise when viewing the helicopter from the top. The tail rotor blades
spin counterclockwise when viewing the helicopter from the right-hand
side.
NOTICE: If the main rotor blades are spinning counterclockwise, make sure you
are in normal mode and reduce the throttle to low immediately. Turn TH HOLD
ON. Disconnect the battery from the helicopter and reverse any two motor wire
connections to the ESC and repeat the motor control test.
❏ Check gears and make sure no teeth are missing
❏ Do a complete control test
❏ Check that servos are functioning properly
❏ Check to make sure flight battery is properly secured
❏ Check to make sure AR7200BX is properly secured
• Always let parts cool after use before touching.
• Always remove batteries after use.
• Always keep people and pets at least 30 feet away when the flight battery
is connected.
• Never operate aircraft with damaged wiring
• Never touch moving parts
First flights should be performed in normal mode and low cyclic and rudder
dual rates until you are familiar with the flying manner of the Blade 450 X.
Discover the rates that fit your flying style.
CAUTION: Always fly the helicopter with your back to the sun and the
wind to prevent loss of flight control.
Landing
Establish a low level hover. Deliberately lower the throttle until the helicopter
lands. Do not give any aileron, elevator or rudder commands when the helicop-
ter is landing.
When the helicopter is in stunt mode:
- The rotor head speed is constant.
- The main rotor will increase negative pitch as the throttle/collective stick is
moved from the middle stick position to the low stick position. Negative pitch
allows the helicopter to fly upside down and perform aerobatics.
Change between stunt and idle up modes in a hover with the throttle near the
hovering stick position.
The helicopter may go up or down when you change between modes due to
the difference in the throttle and pitch curves.
WARNING: Do not use wooden main blades with the Blade 450 X or
injury and/or property damage could occur. Only use Blade 450 X ap-
proved carbon fiber main blades.
If the cyclic control is too slow or too fast, adjust the transmitter dual rates,
expo or throttle curve to fit your liking.
