RECAUTIONS
WARNING!
Failure to follow these safety precautions may result in
severe injury to yourself and others.
• Read through the entire manual before operating this product.
• The GY520 requires 5-10 seconds to initialize when the
power is turned on. Do not move the helicopter and do
not move the tail rotor stick during this initialization
or the gyro may not initialize properly. Once the
initialization process is complete, the tail rotor servo will
move to the left extent and then to the right extent. This
will occur twice. The indicator light will change to solid
blue for AVCS Mode or solid red for Normal Mode.
BEFORE EACH FLIGHT:
• Always check the transmitter and receiver battery voltage to
ensure they have enough remaining capacity to complete
the fl ight.
• Verify that the gyro is operating correctly.
• Verify that the gyro compensates in the correct direction
before flight. If the compensation direction is incorrect the
model will pirouette uncontrollably, at a very high rate.
• Verify that the gyro is operating in the desired mode.
• Verify that the gyro mounting pads are in good condition.
• Verify that the gyro wires are not contacting the frame of
the helicopter.
• The servo type parameter within the GY520 must match the
type of servo you are using. Incorrect setting may damage
the GY520 or the servo, possibly resulting in a loss of control
during fl ight.
