All rules mentioned in this site are based on FAI Volume F3 Radio Control Drone Racing with adjustments and additions where applicable. Participants must follow FAI Volume F3 Radio Control Drone Racing and CIAM General rules
This competition is part of FAI F3U World Cup so all participants must hold a valid FAI Licence or Drone Permission during event. If you don't have a FAI licence and you are either a citizen or a resident of Latvia licence can be obtained by contacting Drone Racing Latvia.
Every drone (which will be used in the event) must be clearly marked (sticker, engraving, etc.) with participants National ID number and FAI Licence Number/Drone Permission. Text size for these markings should be at least 6mm high.
For the event, each pilot can register and use up to 3 drones. Use of unregistered drones is not allowed! Use of other pilots drones (even registered ones) is not allowed! If you crash all of your allocated drones beyond repair your event run is over.
BE ADVISED: In order to validate licence holder event organizers might ask for identification document (ID, drivers licence, passport, etc.) during attendance registration/drone technical inspection process. Failure to provide information that is needed to validate licence holder will be a reason to decline participation!
Currently there are no participation limits although we reserve the right to limit the amount of participants at any time by updating information here. If a participation limit is imposed new participants will be handled on first come first served basis.
Registration deadline is August 9th at 23:59:59 but can be subject to change at a later time.
Currently in Latvia there is no insurance requirement by law. However, we do encourage pilots to obtain one as organizers are not responsible for any damage done during race to third party property or other persons.
Drones must meet these general requirements:
Participants are allowed to use 2.4Ghz and 868Mhz (Crossfire etc.) radio control systems. Both systems must abide by the European Union and Latvian regulations:
Participants are allowed to use only 5.8Ghz TBS Unify (all variants), ImmersionRC Tramp, FuriousFPV Stealth video transmitters in combination with circular polarized antenna. Video transmission must abide by the European Union and Latvian regulations:
Video transmitters not mentioned above cannot be used during event. Linear/dipole antennas are not allowed!
NOTE: We reserve the right to add or remove (removal can't be done less than a month before event) video transmitters from the existing list by updating information here.
Each drone must be equipped with at least 12 RGB LED functioning elements (for example - 2 RGB LED strips containing 6 LED elements each) which are located under drone arms/body or in the back. These RGB LED elements must be switchable either by hand or electronically to adjust to any of these colors - WHITE/RED/ORANGE/YELLOW/GREEN/BLUE/DARK VIOLET/DEEP PINK. During flight each color will represent a video frequency.
Frequency -> Color combinations will be the same as in Betaflight so if you are using Smartaudio/IRC protocol to switch VTX channels in combination with LED VTX channel functionality you are already set (how to set up LEDs in Betaflight).
In order to continue using a drone in upcoming flights after RGB LED elements have been damaged/stopped working at least 6 RGB LED elements must be in working order.
Drone cannot be used if at the start of flight RGB LED elements are not in working order or pilot is not able to set up the correct color.
Must be set to drop or no pulses. Any last RC input holding or other methods that try to keep the drone in the air after it has lost RC signal are not allowed.
Horizon, angle, level and other stabilization (including GPS assist etc.) modes are not allowed. Anti-crash, turtle or similar modes which are meant to either stop the "spin of death" after hitting an obstacle or flip drone after a crash are allowed but use of these can be limited by the assigned judge if drone is deemed not fit for flight.
Event will utilize VTX timing system so there is no need for transponders or 5v output on drones.
Any other situation not mentioned in this section of the site is covered by FAI Volume F3 Radio Control Drone Racing. If a situation that is not covered by either set of rules arises it will be dealt on a case by case basis by the Race Director.
