UAV technology is continuously evolving

– all Harris Aerial customers agree to operate

custom

- made UAV builds as beta testers. This guide is designed to assist you in

understanding safety and operation best practices. Familiarizing yourself with the

equipm ent, understanding basic anatomy of the UAV, and following the guidelines herein

are prerequisites for successful and enjoyable flying experience. Harris Aerial LLC is not

liable for any damages to persons or the environment caused by operator error,

equip ment malfunction or any other events/circumstances. Users assume full liability and

responsibility for the operation of the UAV.

Thank you for flying with us!

# Futaba 14SG

Prior to every flight, ensure all switches are in their default positions, and the Tx

battery is sufficiently charged. We recommend charging your Tx fully for every use.

Use the following infographic to memorize the default switch positions and their

4Your UAV is a machine with numerous moving parts.

f

light conduct a thorough inspection of your UAV’s components. Ensuring all

components are intact will reduce incidence of mechanical failure and will allow

you to have a more enjoyable worry

- free flight.



## WHAT SHOULD I INSPECT?

1. L anding gear:

If you operate a UAV with retractable landing gear, ensure the gear components,

and especially, screws attaching it to the frame of the UAV are not loose and

servos/motors are functional.

2. Motors:

Inspect motor mount screws for ti ghtness. With your hand, grasp each motor and

check for strong attachment to the motor mount. If the motor “wobbles”

, inspect

the four inner screws under the motor mount. Motor replacement is advised if

significant vibration is observed, and steps above are not remedia l.

3. Propellers:

Improper propeller mounting could result in motor failure due to overheating, as

well as decrease in performance and efficiency. Whether you are using self

tightening propeller mounts, or directly mount the prop onto the motor, apply

signif icant torque to the mounting screws.

4. Battery Plates:

Ensure the battery plates’ columns are torqued fully , and the carbon fiber plate is

snug. When using Velcro straps over the plate t o secure a battery, tighten just

enough without bending the plates on either edge.

5. GPS & IMU

Make sure arrows point directly forward

# Calibration

Source: DJI A2 Manua l Calibration is paramount to every successful flight. Perform compass calibration

at every new location. When in doubt

– just do it!

• It is easier to calibrate your UAV with all eight booms (arms) still collapsed

and gimbal off.

• You can lift the UAV chest level by grasping the landing gear mount or any

other part of the UAV that allows you easy positions and frame rotation.

• Grasp the UA V from the rear (t he FRONT of the aircraft MUST face the same

direction as you.

• Initiate calibration switch with UAV still on the ground.

• Yo ur Futaba controller must be 15 ft away prior to calibration trigger.

### Procedure:

1. Turn on the transmitter, it begins to send signals after 1.5secs.

2. Power on the flight control system (Battery/USB). Ensure the

Receiver type is configured as DR16 in the Assistant software.

3. Press the LINK button, hold for 2 secs ; wait until the LED blinks

4. Release the LINK button, the LED turns Green on after

successfully linking. Distance: 2ft

## LED INDICATOR

Knowing your LED indicator sequences is crucial. As a pilot you MUST know what

your UAV is communicating to you . Use the following chart to understand LED

blink sequences and remedial actions, when necessary.
