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 until the helicopter is stable within
a particular fl ight mode.
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 within a particular fl ight mode.
Low Voltage Cuto (LVC)
Once the battery reaches 9V under load, the ESC will
continuously lower power supplied to the motor until
complete shutdown occurs. This helps prevent over-
discharge of the Li-Po battery. Land immediately once the
ESC activates LVC. Continuing to fl y after LVC can damage
the battery, cause a crash or both. Crash damage and
batteries damaged due to over-discharge are not covered
under warranty.
Repeatedly fl ying the helicopter until LVC activates will
damage the helicopter battery.
Disconnect and remove the Li-Po battery from the aircraft
after use to prevent trickle discharge. During storage,
make sure the battery charge does not fall below 3V per
cell.
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 notchy (sticky in places when turning) or draggy.
Wiring
Make sure the wiring does not contact 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.
Gyro
Make sure the receiver is securely attached to the frame. Replace the double-sided tape
when necessary. The helicopter will crash if the receiver separates from the helicopter
frame.
