Drift Calibration

The helicopter has been calibrated in the factory before
shipment, but it is possible that a crash will cause
mechanical distortion of the frame, resulting in a slight
drift in Stability mode. In this situation, please follow the
calibration procedure.
Before beginning the calibration procedure, fully charge the
fl ight battery and ensure the helicopter and transmitter are
bound properly, per the binding instructions.

Post-Flight Inspection and Maintenance Checklist

√
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
Ball Links
the ball, it can separate from the ball during fl ight and cause a crash. Replace worn ball links before they fail.
Make sure the battery is not connected before cleaning. Remove dust and debris with a soft brush or a dry, lint-free
Cleaning
cloth.
Bearings Replace bearings when they become notchy (sticky in places when turning) or draggy.
Wiring Make sure the wiring does not contact moving parts. Replace damaged wiring and loose connectors.
Make sure there are no loose screws, other fasteners or connectors. Do not over-tighten metal screws in plastic
Fasteners
parts. Tighten screws so the parts are mated together, then turn the 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. Damage to these parts
includes cracks, burrs, chips or scratches. Replace damaged parts before fl ying. Verify both main rotor blades have
Rotors
the correct and equal tension in the blade grips. When the helicopter is held up sideways, the main blades should
support their own weight. When the helicopter is shaken lightly, the blades should fall.
Tail Inspect the tail rotor for damage and replace if necessary. Inspect the tail boom for any damage and replace if necessary.
Inspect the main frame and landing gear for damage and replace if necessary. Check the mainshaft for vertical play
Mechanics and adjust the locking collar if necessary. Verify that the main gear mesh is correct and that no tight spots exist in
the 360 degree rotation. Inspect all wires for damage and replace as necessary.

Troubleshooting Guide

Problem
Helicopter is bound to a
Spektrum DXe but will not
respond to control input
Helicopter will not respond
to throttle
EN
Possible Cause
The transmitter is in 9-channel mode
Throttle too high and/or throttle trim
is too high
Helicopter moved during initialization
To Calibrate the Blade 120 S:
1. After initialization, move the transmitter sticks to the
bottom, outside corners, as shown in the illustration.
When the red
and blue LEDs
on the main
fl ight control
board glow solid,
calibration mode
is active.
2. Release the sticks.
3. Slowly advance the throttle to bring the helicopter into
a low hover. The red and blue LEDs fl ash continuosly
to indicate the calibration process has begun. Hold
the hover for approximately 15 seconds, using as little
control input as possible to keep the helicopter steady.
4. Land the helicopter by slowly lowering the throttle.
5. After landing, press the bind/panic button to complete
the calibration process. The LED will show solid blue.
Using the appropriate DXe programming cable and PC or
mobile app, either change the transmitter to 7-channel mode
or download the Blade 120 S model setup fi le to your
transmitter from www.spektrumrc.com
Disconnect the fl ight battery, place the throttle stick in the
lowest position and lower the throttle trim a few clicks.
Connect the fl ight battery and allow the model to initialize
Disconnect the flight battery and re-initialize the helicopter
while keeping the helicopter from moving
