Congratulations on the purchase of your new FPV Drone! You’re about to experience a new type of freedom in the form of 4 propellers.

Before you go ahead and plug that battery in, there’s some very important basic safety tips we have to tell you first!

5 Important Safety Tips!

  1. Always turn on the Transmitter Radio before plugging in your drone.
  2. Ensure you stand at least 2m away from the drone before arming or preparing to take off.
  3. Always remove the propellers before changing any software settings on the drone.
  4. Never leave any charging batteries unattended.
  5. Never fly over other people.

It is important you learn and remember these 5 basic rules before your first flight.
Not following these rules can result in severe injury or bodily harm.

Okay now we’ve got that out of the way, it’s time to get to know your new FPV drone. We know you’re itching to fly, but we recommend reading up on the basics first if you’ve never flown an FPV drone before.

Installing the Propellers

Before attempting to put the propellers on your new model, it’s important to understand the difference between CW and CCW propellers. Each set of 4 propellers includes two of each. CW and CCW are paired diagonally across from eachother.

You’ll need an M5 spanner or propeller tool to fasten the propeller nut. It is very important the nut is reasonably tight and the propellers cannot loosely spin.

Binding your Drone to your Transmitter

If you’ve ordered an RTF (Ready To Fly) package with a transmitter, you can skip this part – we’ve already done this for you. If you ordered a BNF model, you will need to bind the receiver with your transmitter. Please read the guide below.

Practicing on a Simulator First

To save your drone from the first few crashes when flying it for the first time, we highly recommend practicing on a simulator first. There are plenty of great programs out there that will allow you to accurately experience the controls and flight experience of fpv drones using your very own controller.

Our top picks:

To connect your controller to your simulator, you can either use a Simulator USB Dongle, USB cable, or wirelessly by connecting it straight through your drone’s USB port on the flight controller. Tutorial here

Betaflight – the Software on Your FPV Drone

You may have heard the term Betaflight mentioned a lot during your reading. Betaflight is an open-source software project built by hobbyists and other drone enthusiasts. The software runs on your drone’s flight controller which also controls the OSD (on screen display) you see in your FPV headset. Betaflight can communicate messages to you through the form of messages on the FPV feed, LED patterns on the flight controller, and beeper tones if you have one attached to your drone.

Betaflight has a configurator which can be run on Windows/OSX. The configurator software allows you to tweak with just about every setting on your drone, including how the controller inputs feel, the behaviour of your drone, and the configuration of the OSD in your FPV feed.

To connect to betaflight, you’ll typically need a micro-USB cable which plugs into the USB port on your flight controller board. You may also need to install some drivers the first time you connect.

As you grow more comfortable using and flying you new FPV drone, you’ll likely want to change some of the flight characteristics of your quad to better fit your stlye of flying. You may also want to fine tune some settings which includes calibrating your voltage and current sensor to get a more accurate measure of the battery.

The 5.8GHz FPV Video Link

With the introduction of DJI’s HD Digital FPV technology, we now have two main technologies for getting video feed to your FPV goggles. If you’re using an analogue FPV feed, read ahead. Otherwise, you may want to read our article on DJI HD FPV here: Everything you need to know about the DJI HD FPV System.

The video connection between your FPV drone and FPV goggles relies of analogue radio wave transmission – which is the same technology used to get radio in your car. Just like in your car, if you go out of range, your received signal degrades until you see just static. If your signal starts to become full of static, you’ll need to fly your drone closer to get better reception.

Other factors that influence your FPV signal include flying behind metal structures, mountains or hills, buildings and other obstacles, the hardware used such as antennas on your FPV drone or goggles, and also the output power of your video transmitter.

The easiest way to enhance your FPV feed is by using a high powered video transmitter (or VTX) and a decent set of FPV goggles such as the Fat Shark Scouts or better. To set it to maximum power, you will need to change the output power of your VTX by changing the setting in the OSD in Betaflight.

Max range / Drone Failsafes

When you fly your drone, you’ll gradually get a feel for your maximum range. This can be in the form of increasing video static, or through the RSSI (Received Signal Strength Indicator). The RSSI reading can be configured to be displayed on your OSD and is a value between 0-99. Generally you do not want to go below 30-40, which means your receiver is only receiving 30-40% of your input. Keep an eye on this value while flying and you’ll quickly feel more comfortable taking your quad further distances.

If your RSSI drops too low, you will experience a failsafe condition. This is where your drone will disarm itself and drop wherever it is to ensure it does not fly away. The video feed will display a message “FAILSAFE” and you may need to rearm the drone.

Arming / Disarming your Quad

One of the distinct differences between a quadcopter running betaflight and a photography drone like the DJI Mavic is the ability to Arm and Disarm at will. This is essentially turning on and off the motors’ power at the flick of a switch in the case of an emergency, or immediately after a landing or a crash.

FrSky Taranis Q X7 Radio

We generally set the Arm switch to the top left of the controller for quick access. It’s important to develop a habit of reaching for the arm switch if you’ve crashed. By disarming the motors quickly, you can save the motors from a ‘burnout’ where the motor will try to spin even when it’s stuck in the ground. If the motor tries to spin but is stuck, you may damage the internal coils which will result in costly repairs to the Motor or Electronic Speed Controller (ESC) board.

A pre-arm switch (optional) is an extra switch used to prevent the accidental arming of your drone. To arm the quad, you will need to hold the pre-arm switch (usually a momentary switch) down before flicking the arm switch to on. If you don’t do this, the quad will not arm and you will see a “NOPREARM” message displayed on the Betaflight OSD. The pre-arm switch is not set up by default. You will need to enable this yourself through the betaflight configurator if you wish to use it.

Betaflight Flying Modes

There are several different flying modes built into Betaflight which control how your quad responds to stick input. We’ll break these down into the three most basic modes below. We recommend starting on Level mode so you can practice how each stick input feels and practice throttle control.

Acro mode

This is the default setting on your quad if no other mode is set. You have complete control over the quad when flying, with no assistance at all. This is the most common way of flying but certainly not the easiest.

It is worth mentioning Air mode is a variation of Acro mode where the propellers will always spin, even if the throttle is at 0.

Level Mode

Level mode means that if you let the right stick (pitch/roll) center itself, the quad will balance itself back to level. This does not include any momentum or drift as the quad will not hold itself in place. You will still need to apply the correct throttle control as the quad will not keep itself hovering automatically. Level mode also applies an artificial limit to how far your quad can tilt in any direction. This means you will not be able to do any flips or tricks.

Horizon Mode

In Horizon mode, your quad will self balance just like level mode does, except with the artificial tilt limit removed. If you apply a full forward pitch, your quad will continue to pitch forward until it goes upside down.

Betaflight Error Messages

Below you’ll find the most common faults you will see in the Betaflight OSD. For a full list of Betaflight error messages, see the official documentation on GitHub here.

NOGYRO – If you’re seeing this error after a flash, you’ve likely flashed the wrong Betaflight Target to your flight controller. If you haven’t recently flashed your board, this error may indicate a hardware fault.

FAILSAFE – Your quad has experienced a failsafe state. This may be due to a loss of connection between the transmitter and receiver, a receiver hardware fault, or a bad soldering connection which has caused the link between flight controller and receiver to fail.

RXLOSS – Your flight controller has lost connection to the receiver. It may indicate a bad connection or loose wiring.

BOXFAILSAFE – You have activated the ‘failsafe’ mode which is dictated by the Modes tab in the Betaflight Configurator.

RUNAWAY – The likely cause of this is you’ve got either the motors spinning the wrong way, or you’ve put the propellers on wrong. A runaway is a safety prevention to ensure your quad does not go crazy if something is incorrectly configured. This condition is triggered in the first few seconds of flight. It can also occassionally be triggered accidentally by launching too fast.

THROTTLE – You need to ensure the throttle is at 0 before arming. If you’re seeing this and your throttle is at 0 before arming, then your channels are likely misconfigured. You may need to change your mapping from AETR to TAER in the Receiver tab in Betaflight Configurator.

ANGLE – This condition triggers if the angle of the quad exceeds the Arming Angle setting in the Configuration tab in Betaflight Configurator. To disable this check, set the Arming Angle to 180. This fault may also indicate a need to recalibrate the gyro on your quad.

NOPREARM – You have not triggered your pre-arm switch before your arming switch.
