Installation:
1. Mount Gyro on the Helicopter, to avoid fixing air output and heater position.
2. 4CH mode connector:

• Step A: Rudder servo connects to Gyro
• Step B: Insert GYRO connector to receiver (e.g. Futaba is CH4, JR is RUDD)
• Step C: Gyro, GAIN single connector (red) requires to the negative side of the battery power

3. 5CH mode connector:

• Step A: Rudder servo connects to Gyro
• Step B: GYRO connector to receiver (e.g. Futaba is CH4, JR is RUDD)
• Step C: Insert Gyro, GAIN connector (red) to the receiver (e.g. Futaba is 5CH, JR is AUX2 or AUX3), connects to receiver sensitivity switching channel

Attn: Connector Form GAIN required the Transmitter of Dual rate operation

Setting Up the Gyro:
1. Turn on your transmitter.
2. Turn on the power of helicopter receiver, before LED lights turns red to blue, do not move Gyro and helicopter (about 5 seconds), This will influence the set-up.
3. Set up your transmitter
3a. Set OFF for the following fuctions (if there is any) of your transmitter:
--ATS (automatic tail stabilization)
--Pilot authority
--Throttle to rudder mixing
--Rudder to gyro mixing
--Pitch to rudder mixing
--Revolution mixing

3b. Recommended Radio Transmitter Settings

4. Dual Rate adjustment:
4a. 4CH mode: Adjust gyro mount to the proper position
4b. 5CH mode: enter to remote function, adjust gyro mount to the proper position

5. Adjustment before operation:
5a. Ensure the switch dual-rate gyro is on the standard mode or lock mode, this can be checked on the rudder servo.
5b. In lock mode, direction servo acts to single side to the maximum (excluding 4CH mode)
5c. When selecting lock mode to fly helicopter, it has to keep the rotor blade stop (if tail moves to another side) you can use transmitter adjustment to adhust tail move back to netral.
5d. In standard mode, if you find the tail is not fuctioning well, don't adjust transmitter, but only adjust tail & back to neutral
5e. If the tail shakes when dual-rate adjust to the lowest position, you may move Rudder servo to proper position (suggest to adjust to the forth)

HAVE A NICE & STABLE FLIGHT...
