Flying with Patron FPV

In this section you will learn basic flight controls of Patron FPV.

Prerequisites: This tutorial assumes that you have already completed RC Transmitter setup tutorial.

Manual flight

1

Pre-flight check

Make sure, that:

• propellers are facing correct directions and are tightened firmly.

• FPV battery is charged.

• transmitter and FPV goggles are charged. (FPV goggles are optional)

• there is no visible damage to FPV or loose parts.

• other devices, like RC Transmitter and FPV goggles are working properly.

Pair devices

1. Make sure, that transmitter control sticks are in their default position. Left stick must be pushed fully down (zero throttle value) and right stick is in the center.

2. Check if arm switches (3) (4) are in disarmed position. (toggle switches are pushed farthest from you)

3. Turn on Transmitter by holding power button in the middle of the transmitter.

4. Plug in FPV battery, which will automatically turn on FPV.

5. Wait until FPV initializes itself. Successfully initialized drone with GPS lock is signalized by LEDs on the GPS module flashing green.

You can take a look on all GPS LEDs meanings in the following documentation: https://ardupilot.org/copter/docs/common-leds-pixhawk.html

Pairing and using FPV goggles (optional)

This section is a quick guide to set up FPV goggles Skyzone Cobra X V4. (tested)

1. Turn on FPV goggles by holding power button located on the top of the goggles.

2. To find current FPV streaming video channel, hold right scroll wheel located on the top of the goggles, which will open channel menu.

3. Press the right scroll wheel again to start channel scanning. When scanning ends, your goggles will automatically select streaming channel with strongest signal. You can still move across channels using scroll wheel and selecting another one with pressing the scroll wheel.

4. Close channel menu by holding right scroll wheel.

3

Displaying telemetry

You can see part of the telemetry information by holding down button (10). This way you are able to see e.g. GPS coordinates of the drone, or FPV battery voltage.

You can find more information about telemetry screen here: https://manual.edgetx.org/bw-radios/model-select/display

Video recording

You can turn on/off video recording by pressing (9) button. You can also see ongoing recording in OSD HUD through FPV goggles.

In flight controls

We recommend to move the sticks very gently at first. By doing so you can prevent sudden and unexpected changes in movement of the drone and possible crashes.

Controller	Fly direction	LOITER MODE Description
		Ascend/Descend - Changes drone's throttle. Move the stick up to ascend and down to descend.
		Rotate - Changes drone's yaw. Move the stick right to rotate clockwise and left to rotate counter-clockwise
		Forward/Backward - Changes drone's pitch. Move the stick up to fly forward, move it down to fly backwards.
		Right/Left - Changes drone's roll. Move the stick right to fly to the right, move it left to fly to the left.

Changing default flight modes can be done through GCS in Vehicle Setup/Flight Modes by changing Flight Mode 1 to 6.

Emergency stop

Emergency stop is mainly designed to immediately stop all motors whether the aircraft is flying or not. Its purpose is to prevent damage, injury, or further operational issues.

Emergency stop can be activated anytime.

To activate emergency stop push upper switches (3) (4) to their first position (away from you).

It is also used as alternative to Disarm.

6

Arming and takeoff

Always make sure, that throttle stick is on its zero value (pushed fully down) before arming the drone. Not zeroed throttle may result into instant takeoff after arming and loss of control.

It is recommended to take off in Loiter flight mode. Loiter mode maintains the current location, heading and altitude automatically, which makes it suitable for beginner operators.

To use Loiter mode, your GPS has to be successfully connected to satellite network. (signalized by flashing green LEDs when FPV is disarmed)

1. While holding throttle fully down, arm the drone using upper switches (3) (4) by switching it towards you.

2. To take off with the drone, slowly move the throttle stick up, until the drone starts slowly moving up in the air.

7

Landing and disarming

Always check your landing area for obstacles or uneven terrain to avoid damaging or crashing the drone.

1. Switch your drone to Loiter mode (optional, although recommended for beginners)

2. Position your aircraft about 10m above the desired landing area.

3. Gently decrease your throttle using throttle stick until your drone starts slowly descending and hold your throttle stick on the same level.

4. When the drone touches the ground, disarm it by pushing upper switches (3) (4) to its first position (away from you).

5. Wait until the propellers stop spinning.

Always keep your distance from landing or armed drone. Rotating propellers may cause serious injuries.

Post-flight

If FPV is disarmed, turn it off by unplugging the battery.
