Pre-Flight Check List

Before you fly, we suggest that you go through the following pre-flight checklist.

Verify that the batteries are fully charged. A small voltage monitor that connects 

to LiPo balance plug is a good tool for this purpose.

Make sure that the props are tight and not damaged.

Put all transmitter switches in the proper positions.

Turn on the transmitter and make sure the controls move freely in all directions.

Connect the battery to the FORM500 and place it on a level surface. Wait for 
the controller to get a GPS lock on at least 5 satellites.

Calibrate the compass if the Red LED is not steady or if the quad is not at the 

same location as the last flight.

Calibrate the sensors.

Power up and check any accessories that will be operated during the flight.

When the Green LED is flashing, arm the motors and take off.

Hover and make sure the quad is responding to stick inputs from both sticks. 
If the quad is making any unusual sounds or vibrations, land and investigate 
before continuing the flight.
