4, General Operation

4.1 Before Powering-Up the System

All connection must be made before powering up the system. Ensure the GPS antenna is

facing up and not blocked from the sky. Make sure all components are securely ﬁxed in the

plane. The GPS must be kept away from all electronic components, especially the

electrical speed controller, video transmitter and wireless modem transceiver.

4.2 Before Taking-Off

Connect battery for the on-board video system if there is any, turn on the ground video

receiver and display system. Turn the RC transmitter on, make sure the throttler stick is

pulled at the low position. and then connect the power battery to power up the OSD

system. If there is any separated battery pack for RC receiver, power the RC receiver up

before the power battery is connected. Place the plane at the taking off position, and keep

it to be stationary until the position is locked by the GPS, and the HDOP reading is not

more than 3. It may take some time for the position to be locked, and the HDOP reading is

dropped to 3 in the poor weather condition. It is not recommended to take off if the HDOP

reading is more than 3.

4.3 After Taking-Off

You may take off the plane after a standard range check for the radio system and the

plane condition before the ﬂight. Do please prepare to return to the take off position and

land the plane when:

- The power battery is low

- The video battery is low

- The video link is not stable

- The RSSI reading is low

- The HDOP reading is close to 3

- The GPS signal quality indication is low

And the plane must be landed as soon as possible when:

- The video link is not stable

- The RSSI warning is indicated

- Any GPS failure is indicated

- The HDOP reading is suddenly increased for more than 3

4.4 After Landed

After landed, you may press the red reset button on the infrared remote controller while the

OSD system is in the in-ﬂight interface screen to reset the Relative Altitude, Maximum

Altitude Reached, Distance to Home, Home Direction and also the Timer (if it is set to the

“Take-Off Start” mode) back to zero. In the same time, the home position recorded in the

system will be replaced by the current location coordinate.
