Post-Flight Inspection and Maintenance Checklist
Ball Links
Make sure a 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 notchy (sticky in places when turning) or draggy.
Wiring
Make sure wiring does not block moving parts. Replace damaged wiring and loose connec-
tors.
Fasteners
Make sure there are no loose screws, other fasteners or connectors. Do not over tighten
metal screws in plastic parts. Tighten the screw so the parts are mated together, then turn
the screw only 1/8th of a turn more.
Rotors
Make sure there is no damage to the rotor blades and other parts that move at high speed.
Damage to these parts includes cracks, burrs, chips or scratches. Replace damaged parts
before fl ying.
Stunt Mode
Stunt Mode allows the helicopter to fl y inverted and perform aerobatics. The throttle runs continuously when Stunt
Mode is ON, regardless of throttle stick position. Turn Stunt Mode OFF to return control to the throttle stick.
Throttle Hold
Throttle hold is used to turn off the helicopter motors if the helicopter is out of control, in danger of crashing or
both. Activate throttle hold anytime the helicopter is in danger to reduce the chance of damaging the helicopter in a
crash. Throttle hold will stop the motor in normal or stunt mode.
