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.
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. Turn throttle hold off at this
time and confirm the transmitter is still set to normal flight mode. 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, reduce the
throttle to low immediately. Turn throttle hold on. Disconnect the battery from
the helicopter and reverse any two motor wire connections to the ESC and
repeat the motor control test.
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 300 CFX is intended to be flown outdoors or inside a large
gymnasium.
CAUTION: The Blade 300 CFX is intended for pilots with experience
flying aerobatic, collective pitch helicopters. The Blade 300 CFX is
more responsive 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 outside of ground effect to verify proper
operation of your helicopter. You must not set any trim; the flybarless design
of the Blade 300 CFX renders trim unnecessary. Setting trim or sub-trim can
cause an unwanted drift or rotation of the helicopter.
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 300 CFX.
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.
If the cyclic control is too slow or too fast, adjust the transmitter dual rates,
expo or throttle curve to fit your liking.
Flying the Blade 300 CFX
❏Check all screws to ensure that they are tight
❏Check belt tension to ensure that it is not too tight or too loose
❏Check main and tail blades to ensure they are not damaged
❏Check all links to 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
❏Check gears to make sure no teeth are missing
❏Do a complete control test
❏Check that the servos are functioning properly
❏Check to make sure the flight battery is properly secured
❏Check to make sure the AR7200BX is properly secured
Blade 300 CFX Pre-Flight Checklist
Gyro Gain Adjustment
If the tail wags or oscillates, lower the gain on the gyro. On your transmitter’s
gyro menu, decrease the gyro gain values a small amount until the helicopter
is stable within a particular flight mode.
If the tail is drifting while hovering, increase the gain on the gyro. On your
transmitter, increase the gyro gain values a small amount at a time until the tail
starts to wag/oscillate. Afterwards, reduce the gain until the tail stops wagging/
oscillating within a particular flight mode.
