5. Gyro mounting

     The gyro should be mounted to a steady platform which is perpendicular or parallel 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: use a 2-3mmm foam pad only.

 

 

Mounting on a large or a High vibration helicopters: use a 2-3mmm foam pad on each side of the damping shield plate.

 

     There are three directions can be selected for mounting the gyro.

Direction 1:        

Direction 2:            

Direction 3:        

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. 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 modeFutabaH1JR1 servo NORMin 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.

9. Parameter configuration

Turn on the transmitter, connect the gyro to receiver. If the servo type is not selected, disconnect the servos to the gyro. Connect the gyro and the G-BOX with data cable.

Power on the gyro, the G-BOX displays: “Helicox Connecting gyro!”.

If they Link well, the G-BOX displays: “Connect succeed!”.

Then it displays: “Basic setup”.

Generally, you just need to tune the “Basic setup” menu.

9.1 Monitor

In this function, you can check the transmitter configuration and the gyro connection.

     When the G-BOX displays “Basic setup”, Press the “ENTER” button to enter “Basic setup”. Press the “ENTER” button again, the first item is “Monitor”. The first page shows the 4 channels of receiver: “A is aileron channel, “E is elevator channel, “R” is rudder channel, “C is collective pitch channel.

     Use the Servo reverse” function in your transmitter to adjust the signals satisfy the requirements as follows. When you move the rudder stick to the left, the G-BOX displays “L” behind “R”. When you move the rudder stick to the right, it displays “R” behind “R”.

     When the stick of each channel is centered, the value of the channel on the screen should be 0otherwise you should adjust it to be 0 by using the “Sub-tirm” or “Trim” in your transmitter.

     When the stick of each channel is moved to each end position, the value of the channel on the screen should be 100otherwise you should adjust it to be 100 by using the “End point” or “EPA” in your transmitter.

     

      

     Press the “DOWN/DATA- button to switch to page 2, the screen displays the tail gain given by transmitter and current parameters group in gyro.

“G” shows the tail gain given by transmitter. “A”: gyro is in AVCS mode. “N”: gyro is in Normal mode. “Condition” shows the parameters group in gyro. There are two parameters groups in gyro.

 

     Set up a gain switch in transmitter, which is used to control gyro’s working mode (AVCS mode and normal mode). The relationship of the gyro actual gain and the displayed value in some popular transmitters are in the table as follows. We recommend that you can set the gyro actual gain to be about 40%, and then adjust the gain during practical flight. The gain should be raised until the tail begins to oscillate quickly (also called Tail Wag). Once this point has been achieved, reduce the gain a little and do a test flight again. Check and set the gain for each flight mode.
