The most common mistakes made by beginner FPV pilots

The most common mistakes made by beginner FPV pilots are skipping the simulator, flying without a tested failsafe and without an observer, choosing too powerful a first drone and handling LiPo batteries badly. Most of them end in broken propellers, but some can cost other people their health, void your third-party liability insurance cover or cause legal trouble. Below you will find the mistakes instructors see most often, grouped by stage: learning, choosing equipment, configuration, batteries, flying, formalities and what to do after an accident.

Learning mistakes – too little simulator, too much at once

The first and most expensive mistake is going out to a field without simulator practice. In acro mode the drone does not level itself, so you have to build the reflexes beforehand. A dozen or so hours in a simulator will save you more than one set of spare parts.

Other mistakes in this group:

• Rates that are too high at the start. The drone reacts nervously, and you cannot tell what is a hand error and what is the settings. Start with gentle rates, the same in the simulator and on the drone.
• Too steep a camera angle. With a steeply tilted camera you have to fly fast to see the horizon, and without practice that ends in the trees.
• Flying without a goal. A pack without a task is a wasted pack. Set an exercise: hover, straight lines, circles, figures of eight, landing on a spot.
• No analysis. The goggle recording shows where you lost altitude and why a turn was uneven. Review it after every session.
• Comparing yourself with online videos. Smooth freestyle footage is the result of hundreds of hours of practice. Measure your progress against yourself a week ago.

Mistakes when choosing your first equipment

• A powerful 5″ on 6S as your first drone. It is fast, heavy and unforgiving of mistakes, and every crash costs more. To start, choose a light drone under 250 g, and buy a 5″ once you have mastered the basics.
• Incompatible components. The receiver in the drone must support your radio's protocol, e.g. ExpressLRS, and the camera and video transmitter must work with your goggles. Analogue goggles will not receive video from a digital camera.
• Saving money on the radio. The toy radio from the simplest RTF kit has few switches and imprecise sticks. A good radio will serve you for years, in the simulator as well.
• Goggles bought without checking interpupillary distance and focus. A blurred image tires your eyes and brings on nausea sooner.
• Too few packs and propellers, no charger with a balancer. One session means several packs and at least a few sets of propellers.
• A ready-made drone without a class label bought without checking its legal status. Such a drone placed on the market after 1 January 2024 does not fall directly under the transitional provisions for older models¹.

Drone configuration mistakes

• Arming on a stick or on the same switch as the flight modes. Arm with a separate two-position switch that is easy to find with your finger.
• An untested failsafe. Before the first flight, arm the drone without propellers and switch off the radio – the motors must stop or the drone must enter the planned procedure. EASA recommends that the lost-link recovery function be set appropriately for the planned operation².
• Configuring with propellers on. Every change in Betaflight and every motor test is done without propellers. An accidental arm on the table ends in cut fingers.
• Propellers fitted the wrong way round. The drone flips over on take-off or shoots off violently. Check the direction of motor rotation and the propeller orientation before the first take-off.
• No buzzer and unsecured antennas. A lost drone without a buzzer takes hours to find, and an antenna getting caught in a propeller ends the flight at the worst possible moment.
• Too much video transmitter power when other pilots are flying. With analogue you interfere with others and get interference yourself. Agree channels and take off on low power.

LiPo battery handling mistakes

• Flying until cut-off. Deep discharge shortens the pack's life and risks a sudden loss of power. Land when the voltage under load drops to approx. 3.5–3.6 V per cell³.
• Storing charged packs. If you are not flying for a few days, discharge them or charge them to a storage voltage of 3.80–3.85 V per cell³.
• Charging without a balancer, at too high a current or unattended. Charge at 1C or less, with the balancer connected, on a non-flammable surface³.
• Using swollen or damaged packs. Inspect the pack after every crash. A bulge, split wrap or dent is a signal to take it out of service.
• Charging cold packs. After coming in from the frost, wait until they have warmed up to room temperature.
• Carrying packs loose. Transport packs with their connectors protected, in a separate bag or box, so that nothing metal can short the contacts.

Mistakes in choosing the place and during the flight

• Too cramped a place. A drone heavier than 250 g flies in subcategory A3, i.e. in a place without uninvolved people and at least 150 m from residential, commercial, industrial and recreational areas⁴. A light drone gives more freedom, but never flies over assemblies of people⁵.
• Flying behind an obstacle. Trees and buildings attenuate the video and control signals. When the image starts breaking up, you turn back rather than flying on in the hope it will improve.
• Flying into the sun. The camera overexposes and you lose the image at the worst possible moment. Plan your route with the sun behind you.
• Flying after a crash without an inspection. A bent propeller, cracked arm or loose pack will take their revenge on the next take-off.
• Rescuing the drone with throttle. After snagging a branch or landing in tall grass, disarm the motors immediately – otherwise you will burn out a motor or ESC.
• Ignoring the wind. A light drone in strong wind will not make it back upwind. Check the forecast and the conditions on site.
• Flying over water or terrain from which you cannot recover the drone. Before you fly, think about where the drone will come down if something fails and whether you can get to it safely.

Formal mistakes that come to light afterwards

These are mistakes you cannot see during the flight, but which have consequences when something goes wrong:

• No operator registration and no number on the drone. A drone with a camera requires registration regardless of its weight, and you put the operator number on every drone⁶.
• No competency. To fly in subcategory A3 you need to have passed the A1/A3 online training and exam⁵.
• No third-party liability insurance. In Poland the operator of a drone weighing from 250 g to 20 kg must have third-party liability insurance, and failing to have it carries a financial penalty⁷. Importantly, the mandatory policy does not cover damage from flights without the required competency document or in breach of the rules on drone operations⁸. So after an illegal flight you may have to pay for the damage out of your own pocket.
• No flight notification. In Poland you notify the Polish Air Navigation Services Agency (PANSA) of every intended drone operation, in practice via a check-in in the DroneTower app⁷⁹.
• Not knowing the zones. Check geographical zones and their conditions before every flight, e.g. on DroneMap¹⁰¹¹.
• Flying with goggles without an observer. In the open category the observer stands next to you and watches the drone¹². A temporary exemption from the Polish Civil Aviation Authority (ULC), valid until 12 October 2026, allows flying without an observer only within strictly defined limits, including a maximum of 50 m above the ground – check whether it has been extended¹³.
• Exceeding the height limit. The limit is 120 m from the closest point of the surface of the earth¹⁴, and in geographical zones it is sometimes lower.

Mistakes after an accident or losing the drone

The worst response to a crash is chaos. Disarm the motors, remember the last image in your goggles and check that nobody has been hurt. If someone is injured, give first aid and call the emergency services on 112 – the drone can wait. When searching for the drone, start with the recording and the last known point, switch on the buzzer and do not enter private land, a frozen lake or dangerous places.

If the drone has hit a person, caused damage or there has been a dangerous proximity to a manned aircraft, remember the obligation to report occurrences. The operator reports safety-related occurrences to ULC¹⁵. Reports are accepted via the ECCAIRS portal¹⁶, and the deadline is in principle 72 hours from becoming aware of the occurrence¹⁷. Also secure the goggle recording and flight data – they will be useful in establishing the causes and in dealing with the insurer.

After a serious crash, do not take off straight away with the next pack. Check the frame, the electronics mounting, that the motors spin freely, and the condition of the propellers and the pack. A small crack in an arm or a loose wire is easier to spot on the ground than in the air.

Key points

• The cheapest lesson is the simulator; go out to the field with gentle rates, a moderate camera angle and an exercise plan.
• Check the failsafe, the arming switch and the propeller direction before the first flight, and always configure without propellers.
• Protect LiPo packs from deep discharge, store them at storage voltage and charge them with a balancer.
• Registration, competency, liability insurance, a DroneTower check-in, zones and an observer are the conditions for a legal flight in Poland, and without them your policy will not pay out.
• After an accident, people's safety comes first and the drone second; report safety-related occurrences to ULC.
