re-do the compass calibration. Carry out the following procedure to re-mount the GPS module.

In the following diagram (view from the top), the aircraft can appear to be rotating in both clockwise and

counter-clockwise direction, please re-mount the GPS module correspondingly.

Motors Start failure caused by TX stick(s) mid point error too big

If the TX stick(s) mid point error is too big, Motors Start will fail when you execute the Combination Stick

Commands (CSC) and lead to the aircraft will not takeoff.. And the LED will blink Red four times per second

continually to warn you.

TX stick(s) mid point error too big can be caused by the following reasons:

(1)

There is TX stick (except the throttle stick) not at center when power on the autopilot system.

(2)

The TX sticks has been trimmed, which leads to the large deviation of mid point. For example, the

SUB-TRIM has been adjusted for Futaba transmitter.

(3)

The TX stick(s) travel has larger asymmetry.

For the reason (1), please put all TX sticks at the mid point, and then power cycle the autopilot system to

re-record the mid point. If the problem continues, that can be caused by the reason (2) or reason (3), yo

u need to adjust the output range of your TX, and then use the Assistant Software to redo the TX cali

bration. Please carry out the following procedures.

(1)

Connect to the Assistant software, click Basic-> R/C-> Command Sticks Calibration, and push all TX

sticks throughout their complete travel range to see if any stick cannot reach its largest position.

(2)

Adjust the largest travel of TX stick until the cursor on the Assistant software can reach both end

positions, according to your TX manual.

(3)

Power cycle the autopilot system, note that power cycle is required.

(4)

Redo the TX calibration according to the Assistant software.
