Advanced Swashplate Settings; Maintenance - Blade 120 SR Bedienungsanleitung

• While attempting to establish a low-level hover, you can also check to see if any trim adjustments are
required to help keep the 120 SR from constantly drifting in various directions. If you find the helicopter
constantly drifts without any directional control input, land the model before making any adjustments to the
trim settings. Additional details regarding the location and function of the trim buttons are in the
"Understanding the Primary Flight Controls" section of this manual.
- If the nose of the helicopter drifts to the left or right, adjust the rudder trim.
- If the helicopter drifts forward or backward, adjust the elevator trim.
- If the helicopter drifts to the left or right, adjust the aileron trim.
Continue making trim adjustments until the helicopter hovers at a low altitude with very little drifting and
directional control input. If the 120 SR is your first helicopter model, seek help of an experienced pilot to trim
the model for you before making your first flight.
• With your 120 SR properly trimmed and maintaining a stable low-level hover, practice using the rudder,
elevator and aileron controls to familiarize yourself with the helicopter's responses to control inputs.
Remember to keep the control inputs as minimal as possible.
When comfortable with low-level hovering, you can transition to hovering and flying the helicopter at
higher altitudes of three to four feet. At these higher altitudes you will become comfortable with the flight
characteristics of the 120 SR.
• If you feel the helicopter drifting out of control during flight, release all of the controls except for throttle. You
will need throttle to maintain altitude, but because of the inherent stability of the self-stabilizing single rotor
design, the 120 SR will return to a stable hover on its own, if space allows.
• Don't be afraid to set the helicopter down on the ground quickly by lowering the throttle when
approaching walls or other obstacles to help prevent main rotor blade strikes.
CAUTION: Always fly the helicopter with your back to the sun and the wind to prevent loss of flight control.
Once you have gained experience and confidence in hovering the 120 SR, you can attempt more advanced
maneuvers including:
Forward Flight
Pirouettes

Advanced Swashplate Settings

The Blade 120 SR comes with an adjustable
swashplate. Advanced pilots may benefit from a
more aggressive setup. To achieve a more
aggressive setup, pop off the lower rotor head
links and move them onto the longer set of inner
swashplate control balls.
Note: Always attach links to control balls
opposite each other.

Maintenance

Do regular maintenance to keep your Blade 120 SR in safe flying condition.
Make sure a plastic ball link holds the control ball, but is not tight (binding) on the ball. When a
Ball
Links link is too loose on the ball, it can separate from the ball during flight and cause a crash. Replace
worn ball links before they fail.
Make sure battery is not connected before cleaning. Remove dust and debris with a soft brush or
Cleaning
a dry lint free cloth.
Replace bearings when they become notchy (sticky in places when turning) or draggy.
Bearings
Make sure wiring does not block moving parts. Replace damaged wiring and loose connectors.
Wiring
Make sure there are no loose screws, other fasteners or connectors. Do not over tighten metal
Fasteners
screws in plastic parts. Tighten screw so parts are mated together, then turn screw only 1/8th of
a turn more.
Make sure there is no damage to rotor blades and other parts which move at high speed.
Rotors
Damage to these parts includes cracks, burrs, chips or scratches. Replace damaged parts
before flying.
