5. Gyro Mounting
The gyro should mount to a steady platform which is perpendicular to the main shaft and far away
from the engine and other electric devices.
Mount the gyro to the platform by using a soft foam pad, relax the cable of gyro to reduce
transmission of vibrations through the cable. Do not allow the gyro case to touch other parts of the
helicopter.
Mounting on a small electric helicopter: just use a 2-3mm foam pad.
Mounting on a large or a High vibration helicopters: use a foam pad on each side of the damping
shield plate.
There are three directions can be selected for mounting the gyro.

6. Installation of Servo Horns
and Linkages
Make sure all the mechanical parts of the rotor head, the swashplate and the tail rotor are installed
correctly, all parts can move smoothly, and all the servos are installed firmly.
Mount control balls to swashplate servo horns. We recommend the distance from the ball to center
is: 12.5-13mm (250,450size), 14-14.5mm (500size), 14.5-15mm (600 or larger size).
Mount control ball to tail servo horn. We recommend the distance from the ball to center is: 4.5mm
(250size), 7.5-10mm (450, 500size),13.5-15mm(600 or larger size).
Install the horn to tail servo temporarily, adjust the horn position to make it perpendicular to the
linkage, then set the tail pitch to be approximately 8° in the direction that compensates the main
rotor torque by adjusting the linkage length.
Notice: Don’t connect servos to the gyro until finishing the servo type configuration.

7. Set Parameters by using Transmitter
7.1. Transmitter configuration
Power on the transmitter and create a new helicopter model, set the trims and sub-trims of all the
channels to be zero. Set the swashplate mode as a no mixing mode (Futaba: H1; JR: 1 servo NORM)
in your transmitter. Make sure all the mixing functions related to swashplate and tail are turned off.
Do not adjust the collective pitch curve now, remain it as a straight line.
Take DX7 and 8FG for example, conservative configuration shown below.

7.2 Configuration of system menu and setup menu
There are two menus in programming mode: system menu and setup menu.
Notices:
• Always exit programming mode before attempting to fly the model.
• The items of the two menus can be called circularly.
• When complete a setup, press the SET button to save the setup and enter the next item.
• If the servo type is not selected, disconnect the servos to the gyro.
• When complete and save all the setup, restart the gyro to exit programming mode.
7.2.1 Configuration of system menu
Enter the system menu
Turn on the transmitter, connect the gyro to receiver, power on the gyro , rapidly hold aileron stick

In this item, the swashplate tilts to a direction. Now
you can consider the swashplate to be a compass,
the direction of tilt is the compass orientation. Pick
up helicopter and rotate it around its main shaft for
90 degrees, check the swashplate compass
orientation, if it maintains it’s orientation, the sign of
“Pirouette optimization” is right, if it goes to the
opposite orientation, reverse the sign of “Pirouette
optimization”. If the configuration is not complete in
40 second, the swashplate will go to level, you must
press SET button 6 times to enter this item again.
(This is the last item of configuration, you must
complete all the other configuration before this
item)

8.2 Check before each flight
• Always check the transmitter and receiver battery voltage to ensure they have enough remaining
capacity to complete the flight.
• Verify that the gyro is operating correctly.
• Verify that the gyro compensates in the correct direction
• 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.
9. FAQ
Tail oscillate quickly(tail wag, hunting).
• Make sure the helicopter is in good mechanical condition. All shafts must absolutely straight. Limit the vibration as
low as possible. Make sure the tail rotor pushrog is straight.
• Decrease the gyro sensitivity setting on transmitter until 15%(JR:57%).
• Select parameter group 1 (F3C mode) in system menu
Helicopter swing randomly.
• Make sure the helicopter is in good mechanical condition. All shafts must absolutely straight. Limit the vibration as
low as possible.
• Use the accessory shield plate and mounting pad. A coin also is OK.
• Decrease the setting of Rsps parameter within gyro.
Rotate uncontrollable.
• Check the Installation direction of gyro
• Check the Gyro Compensation Direction
• Move all the stick to check the servo direction.
Rotate on a direction slowly and continually, drift.
Remain the airframe immobile and the aileron elevator and rudder stick centered during initialization
Red lamp keep flashing
Error occur during Initialization, restart the gyro
Helicopter unstable when fast Pirouette
Enter the system menu ,check the Pirouette optimization direction again
About gyro initialization
When power on, the gyro needs several seconds to initialize. During initialization, Remain the airframe immobile and
the aileron elevator and rudder stick centered, red yellow and blue lamps flash synchronously. When initialization
complete, the tail servo will move right and then left to indicate.
Quickly dial the gain switch between Normal Mode and AVCS Mode for several times, the gyro will initialize again
