Landing
Establish a low level hover. Deliberately lower the throttle
until the helicopter lands.
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 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 Fusion 270 or injury and/or property
damage could occur. Only use Blade Fusion 270
replacement carbon fi ber main blades.
Gyro Gain Adjustment
• If the tail wags or oscillates, lower the gain on the gyro.
In the transmitter gyro menu, decrease the gyro gain
values a small amount at a time until the helicopter is
stable within a particular fl ight mode.
• If the tail is drifting while hovering, increase the gain on the gyro.
In the transmitter gyro menu, 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 fl ight mode.
Tail 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.
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.
Post-Flight Inspections and Maintenance
Ball Links
Make sure the plastic ball link holds the control ball, but is not tight (binding) on the ball. When a link
is too loose on the ball, it can separate from the ball during fl ight and cause a crash. Replace worn
ball links before they fail.
Cleaning
Make sure the battery is not connected before cleaning. Remove dust and debris with a soft brush
or a dry lint free cloth.
Bearings
Replace bearings when they become damaged.
Wiring
Make sure wiring does not block moving parts. Replace damaged wiring and loose connectors.
Fasteners
Make sure there are no loose screws, other fasteners or connectors. Do not over tighten metal screws
in plastic parts. Tighten screw so parts are mated together, then turn screw only 1/8th of a turn more.
Rotors
Make sure there is no damage to rotor blades and other parts which move at high speed. Damage
to these parts includes cracks, burrs, chips or scratches. Replace damaged parts before fl ying.
Flight Controller
Make sure the AR636A is securely attached to the frame. Replace the double-sided tape when
necessary. The helicopter will crash if the AR636A separates from the helicopter frame.
