How to start in the "Actual Direction Control" Mode

1. Turn on the transmitter and lay it down so the

antenna is pointed at the LED on the back of the

1Si as shown in the photo to the right. Connect

the ﬂ ight battery to the quadcopter. Do not move

the 1Si or the transmitter until the LED stops

ﬂ ashing and is steady. This procedure will help

the 1Si to maintain the correct orientation while

in ﬂ ight or returning to home position.

2. Press the "ICM" button on the top left corner

of the transmitter and hold it down for at least 3

seconds. When the LED on the back of the 1Si

starts ﬂ ashing slowly, the quadcopter is now in

the "Actual Direction Control" mode.

3. Before advancing the throttle to take off, hold

the transmitter so the antenna is pointed at the

LED as described in step 1. Keep the antenna

pointed at the quadcopter at all times to help

the 1Si to determine its position while in ﬂ ight.

Entering the

Adjustment Mode

1. Turn on the transmitter and connect the ﬂ ight

battery to the 1Si. Wait for the transmitter to

link with the quadcopter (rear LED is steady).

2. Press down on the right stick and hold it down

so the transmitter will start to beep.
