Drones can be categorized into Classes. By racing in a specific class,
differences in design, weight, and configuration can allow for a more competitive
and fair race.
Note – As technology and usage advances, these classes may be updated / revised as needed. Please bookmark this page to see the latest version!
Unlimited / Open Class
The Unlimited / Open class is designed for basic groupings during open meets. The class definitions have no restrictions aside from frame size and battery configuration.
|ID||General name||Description||Battery type|
|N||Nano||Less than 25 grams||1S|
|M||Mini||250mm, ~500 grams – Most common racer type||3S|
|L||Large||300-250mm, 750grams or more||3S|
|X||Extra||Any frame size over 350mm or 750grams||Any|
In general, most races are being done with Class I and Class M racers
So You Want To Host a Race
So you’re thinking of hosting your own race. Great! There’s some basic guidelines to make sure your pilots will have fun, the safety of your attendees (both pilots and spectators) will be guaranteed, and everyone will go home happy.
First thing you’ll need is a race course. Designing a course should be done carefully, taking into account the available open space (or, in the case of an ‘in the woods’ or cluttered space, how much of that space you want to dedicate for racing), how easy it is to retrieve lost drones, etc.
Some good guidelines:
- All courses should be be cleared of potentially damageable items
- No spectators, animals, or pilots should be on the course during racing
- Course size recommendations (This is entire length, start to start)
- Class I – 100 meters
- Class M – 200 meters
- All pilots check in and register their craft with the referees. A basic safety check is performed
- All components secured to the frame (motors, FC, ESC’s, etc). No dangling or loose pieces
- Batteries are secured with velcro or similar, and will not easily slide out or shift
- All wires are managed via zip ties or similar, and will not interfere with rotors
- Determine a way to avoid FPV channel collisions (colored cards clipped to receivers is a common practice)
- At the discretion of the site owner / race manager, insurance or a waiver may be required from all pilots.
- Spotters should monitor the entire course to assure the space is safe to operate in. Spotters should be able to quickly and easily relay to the Race Organizer if the race needs to be stopped (Radio communications, air hornes, whistles, etc). If a spotter calls a halt to the race, all pilots must stop and land immediately.
- Some well established signalling mechanism should be used by the referees to call a halt. A handheld airhorn, radios with a specific “HOLD” message, etc.
- Pilots must be aware of race referee with them in the pits and be able to perceive, understand, and respond to conditions reported by the referee.
