RotorCross NZ Racing League Rules

Rev 6 July 2016

Contest Director

The Contest Director is “The Law” at the event. Decisions are Final.

Treat him/her like a God, more so if they are wearing a silly hat or have exceptional facial hair, their powers increase.

Seriously though, we are all here to have a good time, if that’s not on your agenda, then maybe consider not attending.

LED Lights

Lights are not mandatory but heavily encouraged, useful for the spotters, public, lap counters (you WANT them to see your miniquad), and finding it when you unexpectedly land in Jonathans lake.

Video Transmitters
Preferred 5.8 GHz
Frequencies in use 5740, 5780, 5820, 5860 MHz (Band 4/F channels 1/3/5/7)
Frequencies must be able to be changed at the field
Output Power max 600mw
Other Frequencies 2.3/2.5 GHz allowed at some events

Lost Model Alarm
Must be fitted and working, or some other clearly audible method for finding lost craft.
General – We are all here to have fun – its no fun when your stuff doesn’t work, and it frustrates everyone else. Make sure your gear is in good order, transmitters that have been crashed too often, damaged antennas, leads and loose connectors have caused all the issues to date. Make sure you know your gear, you know how to operate it.


Must be set, all motors cut on signal loss from radio transmitter, at their discretion the Contest Director may test all machines before racing, or during the day

Event Rules
Everyone –
Listen to and follow ALL instructions from the Competition Director (C.D.) or their designates.
We only walk onto the course when the racing has finished, not while people are still flying.
When you retrieve a multirotor after the race ensure it is powered down straight away, the next racers are getting ready.
Pilots –
Fly only in designated areas, Fly only at appropriate times.
Keep at least 14 meters away from the pilot area – flying any closer can cause your video transmitter to interfere with the other pilots reception . When finishing a race, land ON the race course, at least 14 meters away from the pilots.
When flying on the track, make sure you are located in the pilot area. Do not fly from any other area.
Only power up your multirotor/video transmitter while in the start/finish area (part of the track) ,we do not power up in the pits, or walking from the pits to the track.
If you need to check your Video channel/Change channel, this is done between rounds, Ensure you have a frequency peg for the frequency you wish to check.
If you are flying before the event, after the event or between rounds ensure you have a frequency peg for the frequency you are using. Make sure you have a spotter, someone who can see the area you are flying in and warn you of any approaching hazards (people/animals/vehicles).

Silly hats are encouraged, and may be mandatory at the Contest Directors discretion. A beanie or baseball/trucker cap does not really cut it….a sombrero however, now you are talking !
Spectators/Pit Crew –
The event is fun to watch, and fun to talk about. Please keep away from the pilots while they are flying (keep away from the pilot area) unless you are acting as a spotter,as we need clear communication with the pilots for lap scoring, penalties, and warning of hazards.
Race Rules
There is approximately 5 minutes between heats, be ready on the start line a minute before your heat starts, race lasts for 2:30 – make sure you land on the TRACK , AWAY from the pilots, at least 14 meters. DO NOT enter course to retrieve your multirotor during racing. As soon as racing has finished, switch off your multirotor (to clear the video channel).

Check you finishing position directly after your race…do not attempt to try and correct and mistakes two weeks later…..


Missing an obstacle, flag, or cutting a corner, you must stop forward flight, and perform a stationary 360 deg turn in the air. Failure to do this can result in a disqualification for that race. Missing 3 obstacles in a row can result in a disqualification.


All flying must be done with spotters, looking over the course for any dangers, members of public, animals, other model fliers, low flying aircraft. You should help with spotting for the heat before yours. Spotters stand in the pilot area.

Race Format

Traditional System

There must be at least 4 pilots registered for a class for it to be official.
Classes raced separately.
Minimum pilots per heat = 2 max =4
Each pilot will get 4-5 rounds per event, per class , your best 3 rounds count towards your placing for the day.
10 points for 1st, 6 for 2nd , 4 for 3rd, 2 for 4th. No points for not finishing, all pilots must compete all laps to count in the results

Alternate System

Most laps, you will have 5 heats, each of 2 minutes (unless stated otherwise) to complete as many laps as possible. The total number of laps determines your placing on the day

Course Design

Race length will be adjusted to be close to 2 minutes, a number of laps to get close to this target will be determined by the C.D. before the start of the rounds. Duration may be specified by the Contest Director
The course should consist of a start/finish line, a number of corners a slalom area and 1 or 2 flyunders to create a “flowing” course that promotes smooth, competitive flying, and allows the maximum number of pilots to complete (too many obstacles results in DNF’s).
The Start/Finish line will be directly opposite the pilots, with the closest part of the track at a minimum of 14 meters away.

Event Flow (recommended)

Course setup before 10am – NO flying before course is set up……get out there and help the organizers.

10am – Pilot Briefing

10am to 11am – Practice time, FREQUENCY board is in USE, you must have a PEG for your frequency on your transmitter while flying/testing. SAFETY CHECK , all competitors multirotors will be checked, not checked = no racing, you must bring your craft for checking during this time, or Before pilot briefing if possible.

11am Racing starts – 4 or 5 rounds then ½ hr break, followed by 4 or 5 more rounds. Will have 10 minute break between rounds for frequency changes

Finish approx. 4:00pm , walk the course for broken bits and pack up.
