Rules

0. Introduction

This document describes the safety and operational regulations governing our drone races to ensure that participants will have a fair competition in a safe environment. Ignorance of the complete rules does not excuse the pilot!

In Slovakia, EU legislation applies, according to which pilots are required to hold an A1/A3 license, be registered with the Transport Authority - Civil Aviation Authority (UAS Operator Registration), have insurance for liability for damage in the area of drone flights (e.g., Coverdrone), and have a registration number affixed to the drone. (At our DRSK races, the organizer will not check this; it is the responsibility of each pilot). For international FAI races, it is also necessary to have an FAI license for the drone, which you can purchase at https://droneracing.aero/. At FAI races, registration and FAI numbers will be checked!

Competitors must be over 16 years old. In the case of competitors under 16 years of age, the presence of an adult or valid guardian who must have a certificate confirming the registration of a Drone Operator (UAS Operator Registration) at the Civil Aviation Authority will be required during the competition.

All drones starting in the race must meet technical requirements. If a drone does not meet all technical requirements, the pilot will not be allowed to participate in the races with such a drone.

The organizer is not responsible for losses or damages caused by any competitor or spectator. Every competitor is required to have valid insurance for liability for damage caused by drone operation. In the event of a damage claim, the pilot (perpetrator) is obligated to take full responsibility for damage caused to both health and property of people.

Participants under the influence of alcohol and/or other intoxicating substances cannot participate in the competition. In case of doubt about the health condition of the participant, the organizer has the right to deny participation in the competition.

Every pilot at registration for the race confirms by signature consent to these rules, instructions of the flight director, and confirms that they have the necessary experience to participate in the event.

1.0. Organizer / Race Director

The organizer is authorized to change rules during the races. Every pilot is required to follow the organizer's instructions. For non-compliance with the organizer's instructions, the pilot may be disqualified from the entire event.

The event organizer is responsible for preparation, organization, and supervision of the event and is responsible for ensuring compliance with applicable rules and safety throughout the event. The race organizer has the final word in resolving all conflicts or disputes.

In addition, the race organizer often performs many of the following tasks, which can be delegated:

1. Laptimer operation (software and results)
2. Safety officer
3. Announcer
4. Technical inspector

1.1. Technical Inspector / Chief Safety Officer

The Chief Safety Officer / organizer is responsible for pre-flight inspection of the aircraft to verify racing eligibility and appropriate participant permits.

1.2. Track Safety Marshals

Additional safety personnel may be positioned around the track perimeter to keep spectators away from the racing track and provide additional visibility of crashed drones.

1.3. Observer / Spotter

Every pilot must have an FPV observer/spotter unless the race judges determine otherwise. More info in section 4.3.

2.0. Technical Requirements

2.1. Video Transmitter (VTX)

5.8 GHz video transmitter may only be turned on at the race track or by arrangement with the flight director. If a pilot turns on the video transmitter outside the race track without the flight director's consent or interferes with a flying pilot's video, they may be disqualified from the entire race or otherwise penalized by the flight director.

After finishing their flight (heat), every pilot must immediately disconnect the battery from the drone so as not to interfere with the video signal for other pilots.

Video transmitter frequency will be assigned to the pilot at the beginning of the race during online registration verification. During the race, the frequency may be changed for the pilot when groups are redistributed.

Analog transmitters and HD-Zero transmitters

Video transmitters with output power of 25mW are permitted and must be set to the assigned frequency. We recommend VTX transmitters: TBS, Rush, Foxeer, and HD-Zero.

Digital transmitter DJI and Walksnail

Video transmitters using digital transmission with output power of 25mW, bitrate 25Mb/s (7 channels) are permitted and must be set to the assigned frequency.

The DJI O3 and O4 unit must be in 10/20MHz mode (7 channels) and have Racing Mode (O4) enabled.

Required Betaflight settings:

1. OSD element – VTX channel and power and pilot NAME
2. PIT MODE

All pilots fly together – analog + digital together in a group. Pilots with digital (DJI, Walksnail) sit at least 3+ meters away from analog pilots.

WARNING - At some races, DJI and Walksnail systems may be prohibited!!!

A pilot who has VTX transmission power more than 25mW on their drone may be disqualified from the flight or even from the entire event.

Frequency Table:

2.2. Weight and Frame

Maximum permitted flight weight of the drone (including battery) is maximum 800g

Maximum permitted distance between two motors on the diagonal is 305mm (5" drone and smaller). The frame must be carbon fiber. Other frame materials are not permitted.

2.3. Batteries

3-6S cell Li-Po batteries are permitted. Maximum permitted voltage per cell is 4.25V, meaning maximum voltage of 17V for 4s battery and 25.5V for 6s battery. Battery voltage measurement may be performed before each flight in the qualification and elimination phase of the race. Battery capacity is not limited, however, the drone together with battery and propellers cannot exceed 800g.

2.4. Propellers

Propellers of any number of blades and pitch are permitted. Maximum propeller size is 5.2". Propellers must be plastic (carbon, wooden, or metal propellers are not permitted).

2.5. RC System

RC systems using 2.4GHz or 868MHz bands and maximum power less than 100mW are permitted. The RC system must have FAIL-SAFE enabled to ensure immediate motor shutdown (drop).

2.6. LED

Drones do not need to be equipped with LEDs. However, they are welcome. LED lights are mandatory for all night flights. LED strips should then be mounted on the drone arms. It is recommended to have 4 LED strips with color change capability: Blue - Green - Red - Yellow.

2.7. Antennas

Omnidirectional antennas are recommended. For analog and HDzero systems, RHCP polarization is recommended. LHCP polarization is recommended for digital Walksnail and DJI systems if permitted at the race.

2.8. Registration Number / FAI License

At international FAI Drone Racing World Cup, every drone must have the pilot's registration number and FAI license number (or FAI drone usage permit) affixed.

Letters and numbers must be readable (without aids) from arm's length and must appear at least once on each drone.

3.0. Technical Inspection

At the beginning of races, every pilot is required to undergo technical inspection. Each pilot submits all drones they plan to fly in the race for inspection (maximum number of drones is 3). A drone that failed inspection (in terms of materials, workmanship, construction details, size, weight, or evidence of damage) may not be used in the race.

A pilot may only use their own drones at the race. It is prohibited for a pilot to fly during the race with another pilot's drone! Pilots who violate this may be disqualified from the entire event.

During technical inspection, Fail-Safe mode is also tested - the pilot arms the drone, adds 30% throttle, and turns off the transmitter. Motors must stop immediately *(Fail-Safe mode must be set to drop in Betaflight). During failsafe demonstration, propellers must be removed from motors! This mode is mandatory and drones that don't have it functional will be eliminated from the race.

During technical inspection or at latest during training flights, pilots will also have VTX channel and power and pilot NAME OSD elements checked.

During races, the flight director may perform random drone inspections. If a drone does not meet any of the requirements, it cannot be used further in the race. If a pilot does not repair or withdraw the drone and continues to fly with a damaged drone, they will be excluded from the race.

All drones must have a valid registration number affixed as required by legislation. This will only be checked at FAI World Cup races.

4.0. Race Rules

4.1.0 Pilot Registration Verification

At the beginning of races, along with technical inspection, verification of online registration and payment of registration fee will occur. Pilots will then be assigned a frequency for their video transmitter and each pilot will be placed in a flight group. Group composition and order in races will be determined by blind draw, or pilots will be added to groups in the order they were progressively registered. Then technical inspection of drones the pilot wants to fly during the race will occur.

4.2.0 Briefing

After pilot registration, a briefing will occur that all pilots are required to attend. During the briefing, pilots will be informed about the schedule of race proceedings and brief rules. Pilots together with the flight director will walk the entire track and be informed about individual obstacles and how to correctly fly through each obstacle. During the briefing, pilots will be informed about safety boundaries of the field (if they exist). If a pilot flies outside the safety boundaries, they will be disqualified from the flight.

4.3.0 Spotter (Observer)

During drone races, a spotter monitors a pre-assigned pilot either through goggles or on a monitor and reports pilot errors. If a pilot doesn't fly the track in the pre-determined manner or skips an obstacle and doesn't return to correct it, the spotter first alerts the pilot and if the pilot doesn't correct their error, the spotter reports it to the race director and the pilot will be disqualified from that flight.

Spotter use is mandatory in qualification and elimination flights. Spotters for currently flying pilots are pilots from the next group.

Each spotter monitors the pilot on their frequency – pilot on R1 monitors pilot on R1, etc. If a spotter cannot participate in monitoring a pilot (repairing their drone, etc.), they must find a replacement and inform the flight director about the situation, otherwise the flight director may decide on their exclusion from subsequent flights!

The spotter also monitors their surroundings and informs the organizer and pilots of dangerous situations.

Image transmission for spotting will be provided by HDzero Event VRX transmission to a monitor (analog and HDzero image).

The DJI or Walksnail pilot must provide their image to the organizer throughout the flight by connecting their goggles to an HDMI converter via USB-C, or alternatively arrange spotting by another pilot with the same image transmission system. (not yet supported, work in progress)

At some races, DJI and Walksnail systems may be prohibited.

Despite the fact that race proceedings (all flights) will be recorded by the organizer to PC, it is advisable for every pilot (and possibly spotter) to record DVR footage, which if needed (mid-air, etc.) can also be examined by the flight director.

4.4.0 General Rules

During the event and before its start, any flights on the race track are strictly prohibited, except those planned or permitted by the organizer!

In case of violation of this rule, the relevant competitor may be penalized up to disqualification from the event.

Pilots, spotters, and spectators at the race may move exclusively behind the safety net and in designated areas unless otherwise permitted by the organizer. The organizer is not responsible for any injury if this regulation is not followed.

At the start of each flight, pilots place their drones on the prepared starting stands. If a pilot for some reason cannot use the prepared stand, they may place their drone in the area behind/beside the starting stand by arrangement with the organizer.

After the flight group is announced, the pilot has a time limit of 2 minutes to place the drone on the starting stand. After placing the drone on the starting stand, pilots have 30 seconds to exit the flight area. If the drone or pilot is not ready after the time limit expires, the pilot is disqualified from the flight and goes for their drone together with other pilots only after the flight ends (unless the flight director determines otherwise).

Pilots race together in individual groups they were placed in during registration verification.

Each pilot uses only the frequency assigned to them either at the start of races or during races when groups change for image transmission.

The pilot is required to fly through all obstacles on the race track in the correct order and correct manner as informed at the briefing. If a pilot misses an obstacle or flies through it incorrectly, they are required to immediately correct this error and fly through the obstacle correctly, otherwise they will be disqualified from that flight. If during this corrective maneuver a collision occurs with another pilot, the pilot performing the corrective maneuver will be disqualified from the flight.

After finishing the flight, the pilot is required to safely land at the designated location.

All pilots flying in the current group remain quietly seated at the pilot seat until the last pilot finishes their lap and lands. All pilots go for their drones together and immediately disconnect batteries from drones, DJI and Walksnail system pilots also turn off goggles.

Pilots use the prepared pilot seats in the safety zone. Each pilot seat will be labeled with the video transmitter frequency. Pilots may only fly when seated at one of these chairs.

Proper sporting conduct is required at the race. Examples of inappropriate conduct include, among others: influencing races or another pilot's equipment through speech or any kind of manipulation or aggressive behavior (under the influence of intoxicating substances). No harassment of organizers, pilots, sponsors, or spectators will be tolerated!!! Pilots with unsportsmanlike conduct may be disqualified from the entire event.

The organizer is not responsible for damages caused by competitors.

4.4.1 Timeout

Every pilot is entitled to one 5-minute TIMEOUT but only during elimination! During qualification, pilots are not entitled to timeout. The pilot either loses their qualification flight or may be moved to another group with fewer pilots, based on the organizer's decision and possibilities.

4.4.2 Crash

If a pilot crashes but is able to continue flying without outside help (using Turtle Mode = Flip Over After Crash), they may continue the flight. However, if they are unable to continue the flight, they are required to wait until all pilots finish flying on the track and only then can they go to retrieve their drone on the track. The crashed drone's pilot who cannot continue flying must immediately switch VTX to Pit mode to minimize signal interference for flying pilots.

The competitor must clearly indicate that they have finished the flight by removing goggles from their head. The pilot remains quiet in their place until other pilots finish their flight.

4.4.3 Track Condition Change:

During training flights, race restart for a fallen obstacle does not occur (pilots fly as if the obstacle were there). The pilot does not use the situation to their advantage.

During qualification and elimination flights, a restart / re-run of the flight may occur, at the organizer's discretion.

After completing the current lap, the organizer repairs the obstacle.

4.4.4 Drone Fire

A fire extinguisher will be placed in an easily accessible and visible location. All pilots and spectators will be informed before the flight about the location of the fire extinguisher, container for burning batteries, and first aid kit.

If a drone / battery starts burning during flight, the pilot of the damaged drone is required to land as soon as possible, or immediately disarm the drone. Other pilots immediately land at the designated location. After extinguishing the drone, there will be a flight restart. If the pilot of the damaged drone has a spare drone, they participate in the new flight. If they don't have a spare drone, they are excluded from that flight.

4.4.5 People on Track

If people run onto the track and would be endangered by flying drones, all pilots are required to immediately safely land at the designated location. If people are near the landing zone, pilots land anywhere else on the track so as not to endanger anyone. The organizer then announces a restart.

4.5.0 Flight Repeat / Restart / Rerun

In training and qualification rounds, flights are not repeated, only in exceptional cases recognized by the flight director (e.g., fallen gate, fire, people on track, unless the organizer determines otherwise).

Pilots must continue racing until the race director calls for a restart. Only the director can call for a restart. Pilots should ignore any external instructions, influences, or encouragement from spectators and should only follow the director's instructions.

When a restart is called during elimination rounds, a pilot who crashed by then will not be able to participate in the new flight. Only pilots who were flying at the time of the restart announcement will participate in the restart. This rule is applied at the race director's discretion.

Restart occurs:

1. If a critical safety incident occurs (such as fire or unauthorized person on track), which requires the organizer to stop the races.
2. If an obstacle collapse occurs (gate, flag, etc.) during qualification and elimination. Whether there will be a flight restart or racing will continue as if the obstacle were there (like during training flights) depends on the organizer.
3. External influence preventing one or more competitors from fair competition, such as disrupted video transmission of one of the pilots due to connection of another pilot, proven by DVR, the pilot may request the race director for a flight repeat. If a pilot wants to request a flight repeat, they must immediately land and report the situation to the flight director. If the pilot continues flying, they lose the ability to request a flight repeat.
4. Deliberate interference by a competitor participating in the races, found to have provided them with an unfair advantage over other competitors in those races.
5. If the organizer / timer operator is alerted to a technical problem during the start procedure, they must immediately stop and reset the flight start.
6. If two or more drones collide (mid-air) in the air before the first gate and the incident results in unintentional change of flight path of any of the involved drones, then involved pilots may immediately request a restart, but must land immediately. If drones continue flying through the first gate, races are not restarted!

Only one restart caused by such a collision will be permitted per flight. Competitors will have the opportunity to change their battery on the drone before the restart.

Restart does not occur: 7. Mid-air collision beyond the first gate is in no case a reason for flight repeat. 8. Drone fails to take off from starting ramp, falls to the ground and doesn't take off = Pilot out of races. 9. Pilot lost video for unknown reason = Pilot out of races.

4.5.1 False Start

Any competitor whose drone leaves its starting position before the start signal and passes through the first gate will be disqualified from that flight.

If a drone leaves its starting position due to factors beyond the competitor's control (e.g., during arming), the competitor must immediately land on the ground and start the race from the ground (i.e., from the "back of the starting grid"). A competitor who starts from the ground and collides with another drone in the air during start will be disqualified from the flight.

As soon as disqualification is announced, the relevant pilot must immediately land. Violation of this requirement may lead to disqualification of the relevant pilot from the entire event.

4.5.2 Exclusion from Restarts

1. Any pilot who caused a safety incident
2. Pilot who at the time of this event had already signaled they were out of the races (by removing their protective goggles)
3. Pilot found to have given themselves an unfair advantage by violating the rules

Competitors will have the opportunity to exchange their battery for a new one before the restart.

4.5.3. Safety Problem

A competitor may be asked to stop flying if the organizer determines that the model no longer meets acceptable technical requirements. This could be, for example, when the model is damaged after a collision or crash, or when the battery is hanging from the drone.

In case of a serious safety problem, the race director may decide to stop the races and disqualify the competitor who was responsible for the safety problem. Races will be restarted for competitors who were not disqualified and were still in the air when the safety problem occurred.

4.5.4. Individual Repeat Flights

The possibility of an individual repeat flight will be considered in the qualification phase only in situations where an incident beyond the competitor's control prevented them from completing the flight.

Repeat flights will be organized at the end of the respective qualification round or as part of any flights that have fewer than the required number of competitors.

For a competitor who is granted a repeat flight, the original flight for which the repeat flight was granted is definitively cancelled.

During the rest of the event (elimination rounds, final round), individual repeat flights will not be granted.

4.6.1. Flight Disqualification

A competitor may be disqualified from a flight under the following circumstances:

1. If they start before the start signal. (see 4.5.1)
2. If they cause a collision with another drone while performing a corrective maneuver. (see 4.4.)
3. If they fly off the track / off the area designated for flying and landing (crossing the safety line).
4. If the pilot flies after removing FPV goggles.
5. If the pilot performs a celebration maneuver, especially after completing the flight.
6. If the pilot dangerously pilots the drone and endangers race participants.
7. If the pilot arms their drone on the starting stand and thus endangers other pilots placing their drone on the stand.
8. If they are responsible for a safety problem. (see 4.5.3)

The race director decides on disqualification. If a competitor is disqualified, they must land immediately upon being informed. In no case will their result in that flight be valid.

If a competitor disqualified from races is deemed insufficiently cooperative in landing, the affected competitor may be disqualified from the event.

4.6.2. Event Disqualification

Event disqualification may be considered in the following situations:

1. Use of unauthorized RC equipment (see 2.5.) or other equipment not in compliance with rules.
2. Video transmitter power output exceeds maximum permitted amount (see 2.1.).
3. Unauthorized activation of video transmitter and interference with flying pilot's signal (see 2.1).
4. Use of the same model by different competitors during the event (see 3.).
5. Use of a model that does not meet specifications stated in the rules (see 2.1. - 2.8.).
6. If flights are made on the race track other than those planned or approved by the organizer (see 4.4.).
7. If the competitor does not land after disqualification for false start (see 4.5.1).
8. Cheating or unsportsmanlike conduct according to CIAM General Rules (see CIAM general rules C.19, also see 4.4.).
9. If a pilot arms their drone on the starting stand and injures another pilot placing their drone on the stand.
10. A pilot who exhibits dangerous behavior or is under the influence of intoxicating substances will be disqualified from the event!

4.7. Race Procedure

4.7.1 Training

Pilots fly in groups of 3-4-6 (unless the flight director decides otherwise).

Pilots start consecutively (Staggered Start) and the time limit is measured from passing through the first gate.

Pilots may agree among themselves on the order of starting to avoid collisions.

The organizer / timer operator clearly announces "Pilots, arm your quads", signaling that the start has begun. After an interval of 2 to 4 seconds, one clear tone sounds, signaling the start of racing. There will be no countdown before the start signal.

A time limit of 3 minutes is available, during which the pilot tries to fly as many laps as possible. The time limit is measured from passing through the first gate and is measured separately for each pilot. Once the time limit expires, the pilot completes their current lap and lands.

The goal of training is familiarizing the pilot with the track and testing the racing drone. Organizers use training flights for equipment checks.

Training flight results are not counted. Training is not mandatory! If a pilot is not interested, they don't have to participate.

4.7.2. Qualification

Pilots fly in groups of 3-4-6 (unless the flight director decides otherwise).

Pilots start consecutively (Staggered Start) and the time limit is measured from passing through the first gate.

Pilots may agree among themselves on the order of starting to avoid collisions.

The organizer / timer operator clearly announces "Pilots, arm your quads", signaling that the start has begun. After an interval of 2 to 4 seconds, one clear tone sounds, signaling the start of racing. There will be no countdown before the start signal.

At DRSK races, a time limit of 2 minutes is available, during which the pilot tries to fly as *fast as possible and as many laps as possible (*only the 2 best consecutive laps from all in that heat count - TOP 2 Consecutive). Once the 2-minute time limit expires, the flying pilot must land with their drone (does not complete their current lap).

At FAI races - A time limit of 3 minutes is available, during which the pilot tries to fly 3 laps (laps) as fast as possible. Once the pilot completes 3 laps or the 3-minute time limit expires, they must land with their drone (does not complete their current lap).

After all pilot groups have flown, a new qualification flight (heat) begins. Qualification flights repeat until the predetermined time of day or number of flights.

Final ranking of pilots in qualification is determined by one best flown flight (heat).

At FAI races, pilot groups are re-drawn each qualification round (or after three rounds) to prevent the same competitors from flying in the same group during all qualification rounds.

At the end of the qualification stage, a ranking will be compiled that reflects the best result achieved by each competitor in their qualification flights.

According to the ranking from the qualification stage, pilots will be divided into the first groups of elimination rounds.

4.7.3 Final Flights

Finals proceed in double elimination format. In case of bad weather, finals will proceed in single elimination format, or the final ranking will be determined according to qualification results.

1. Double Elimination (Double elimination bracket / Double knockout / DKO)

The top 16, 32, or 64 pilots advance from qualification to final flights, depending on the total number of pilots at the race. Pilots fly in groups of 4. All pilots start together (*Hole Shot). *Time limit is measured from the tone.

The timer operator clearly announces "Pilots, arm your quads"", signaling that the start has begun.

After an interval of 2 to 4 seconds, one clear tone sounds, signaling the start of racing. There will be no countdown before the start signal.

At DRSK races, eliminations proceed in "First-to-X Laps" format, also known as Headsup Races, where the race ends when the first pilot passes through the start/finish gate and completes the required number of laps (3). For each subsequent pilot, the races end when they pass through the start/finish gate next, regardless of the number of laps they complete.

If a pilot crashes on the track and cannot take off (Turtle Mode = Flip Over After Crash), their last time at which they passed through the finish gate counts. It doesn't matter how far they flew in that lap.

At FAI races, a time limit of 3 minutes is available, during which the pilot tries to fly 3 laps (laps) as fast as possible. Once the pilot completes 3 laps or the 3-minute time limit expires, they must land with their drone. (Pilot ranking is determined based on recorded time needed to fly 3 laps.)

If a pilot crashes on the track and cannot take off (Turtle Mode = Flip Over After Crash), their last time at which they passed through the finish gate counts. It doesn't matter how far they flew in that lap.

The first half of pilots in the group (2/4) advances directly to the next elimination flight, the second half of pilots who lost or did not finish the races have one more chance and advance to "losers bracket". If pilots also lose in "losers bracket" (i.e., lose for the second time), they definitively end the races.

A pilot who only loses once and thus enters "losers bracket" still has a chance to reach the grand final and win the entire race.

In the last final flight (heat), pilots fly until one pilot wins twice - CTA (Chase The Ace).

2nd - 4th place is determined by the sum of points earned in the final.

If two pilots have the same number of points, ranking is determined by the last final flight.

2. Single Elimination (Single elimination bracket / Direct elimination)

Proceeds the same as Double Elimination, however, The first half of pilots (2/4) advances to the next elimination flight, the second half of pilots ends the races.

In the last final flight (heat), one win is enough for the pilot.

5. DRSK League Point Allocation

N = number of pilots at the race

6. Safety Guidelines and Brief Rules

1. Pilots are required to follow the organizer's instructions. The organizer may interrupt the race or flight for safety reasons at any time; all flying pilots must land immediately.
2. If safety guidelines are not followed, the organizer is not responsible for any injuries and damages incurred.
3. Every pilot is fully responsible for their flying and any damage to health or property of third parties.!!!
4. Pilots must not consume alcoholic beverages or other addictive or psychotropic substances before and during the race.
5. For violation of safety guidelines, pilots may be immediately excluded from the race.
6. Pilots must not turn on their drone outside the track without the flight director's consent (if you have any problem and need to try something, change the video channel, come to the organizer who will choose an appropriate moment for you to turn on the drone).
7. Flying is only permitted to the height necessary to overcome obstacles.
8. Flying outside the marked track is prohibited.
9. Entering the track without the flight director's consent or invitation is prohibited.
10. Pilots arm their drone on the starting stand only when pilots are at a safe distance (min. 1.5m)
11. Every pilot has their spotter from the next group who monitors the pre-assigned pilot either through goggles or on a monitor and reports pilot errors
12. All pilots flying in the current group remain quietly seated at the pilot seat until the last pilot finishes their lap and lands.
13. Pilots, spotters, and spectators at the race may move exclusively along the safety net and in designated areas.
14. The track can only be entered when all pilots have finished their current lap.
15. Pilots are required to safely land at the designated location.
16. After landing the drone, pilots immediately disconnect the battery; digital system pilots also turn off goggles.
17. Every drone must have functional Failsafe on Drop, OSD element – VTX channel and power and pilot NAME and functional PIT MODE
18. If pilots do not have 100% control over their machine, they are required to immediately turn off motors - activate Failsafe.
19. Every drone must have VTX power set to 25mw, digital 25mw and 25mbs (7 channels), DJI O3 and O4 must be in 10/20MHz mode (7 channels) Racing Mode with assigned VTX channel set. For analog VTX, functional Smartaudio.
20. Video transmitter frequency (VTX channel) may be changed for pilots during the race.
21. If a mid-air collision occurs before the first gate during an elimination flight, the flight is repeated. Mid-air collision after the first gate is in no case a reason for flight repeat.
22. If there is a change in track condition during the flight (fallen gate), pilots must fly as if the obstacle were there (unless the organizer determines otherwise).
23. Every pilot is required to clean up their area before leaving the race and keep the venue clean
24. Every pilot understands that if it rains, we may use qualification ranking to determine winners.
