Gyro Gain Adjustment; Blade Helicopter Belt Tension - Horizon Hobby BNF Basic Blade 270 CFX Manuel D'utilisation

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 helicop-
ter may crash during takeoff.
CAUTION: Always fl y the helicopter with your
back to the sun and the wind to prevent loss of
fl ight control.
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 fl ybarless design of the Blade 270 CFX
renders trim unnecessary. Setting trim or sub-trim can
cause an unwanted drift or rotation of the helicopter.
First fl ights should be performed in normal mode and low
cyclic and rudder dual rates until you are familiar with the
fl ying manner of the Blade 270 CFX . Discover the rates
that fi t your fl ying style.

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 at a time until the helicopter is
stable within a particular fl ight mode.

Blade Helicopter Belt Tension

Belt tension that is too tight results in loss of power and causes the belt to wear more quickly. Tension that is too loose
can cause belt damage and loss of tail rotor control in fl ight.
To check for proper belt tension:
1. View the tail rotor drive belt through the opening at the
back of the main frame.
2. Use a hex wrench or standard screwdriver to compress
the belt through the opening.
3. Apply light pressure on the belt, compressing the belt
toward the left side of the tail boom.
4. The belt tension is correct if the compressed side of the
belt reaches approximately halfway to the opposite side
of the belt.
a. If the compressed side of the belt reaches farther than
halfway to the other side of the belt, the tension is too
loose.
b. If the compressed side of the belt does not reach
halfway to the other side of the belt, the tension is too
tight.

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 helicopter is landing.
When the helicopter is in stunt mode:
• The Castle Creations Talon 35 ESC comes pre-pro-
grammed in Governor mode. To alter the settings, use
the Castle Creations "Castle Link". Do not adjust the
throttle curve in the transmitter.
• 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 fl y upside down and perform
aerobatics.
Change between stunt and idle up modes in a hover with
the throttle near the hovering stick position.
WARNING: Do not use wooden main blades
with the Blade 270 CFX or injury and/or property
damage could occur. Only use Blade 270 CFX approved
carbon fi ber main blades.
• 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.
To adjust belt tension:
1. Loosen the two horizontal stabilizer screws.
2. Loosen the 2 screws at the back of the main frame.
3. Slide the boom forward or aft to adjust the belt tension.
4. When the belt tension is properly adjusted, tighten
the 2 screws at the back of the frame.
5. Tighten the horizontal stabilizer screws.
