If GPS antenna is laid at Point B, then B’ coordinate value is the offset of
GPS (Figure 3. 32).
As for the same reason, users can get GPS offset by the position of
GPS installation. If users install it at the point of 1/2 length of the tail pipe
approximately, the offset values of y and z is usually 0. Then users only
need to find out the distance between GPS and the c.g. of helicopter in x
direction. Pay attention to the positive and negative of GPS’s offset
value in x direction, and it should be always negative.
Attention：
1. By default, users do not need to change the offset value of GPS in y and
z directions in the software. But if the users do not install GPS in the
recommended position, you can modify the value of y and z by clicking
“Advanced”nearby.
2. To set the expected parameters into the Main Controller to finish setting,
do click “write” after filling the parameters in
3. “Meter” is the unit of all the offset parameters
Note:

1 :
The way to determine the c.g. of helicopter: take down the main rotor, tie the long line with gravity
hammer to the tail pipe, raise the helicopter’s tail, and let the helicopter and the ling hang down
naturally. Then the intersection point of the line and the helicopter is the c.g. of helicopter.

STEP2.
【Autopilot/ Manual Mode Setting】
1）
Click “next” button after finishing the operations above to enter
autopilot/manual mode setting. After turning on the remote control, users
can try to shift autopilot/manual switch. Then users can notice the slide
also shifts between the topside and bottom side, which shows the
autopilot/manual switch, has linked correctly. Users should set the switch
normal and reverse according to the slide direction (upward pushing,
slide locates upward side, and vice verse)

In the default situation, the TRVL ADJ (End Point in Futaba) of
manual/autopilot channel should be 100%. Transfer the up and down
TRVL ADJ to 0% and set this position as Fail Safe. Refer to the Figure 3. 34
after turn off the RC. 4.2 Fail Safe setting will lead users to complete the
unfinished part of fail safe setting.
