Each club meeting the club runs 3x 5min qualifying heats with the fastest drivers over those 3 heats determining the grid for the 20 minute final. The cars are fuelled up before the start of each heat for a few minutes warm up and then each car is sent off on their qualifying runs with your 5 minutes starting as you cross the line for the first time. This means you are always racing against yourself for the most number of laps in the best time to determine your grid position.
Finals are a staggered grid with all cars starting in the position determined by their qualifying results. Finals are 20mins long so are required to pit for fuel every 5 mins or so to complete the race. Finals at national events can be up to 45mins long meaning drivers have to also pit for new tyres as well as fuel and are required to concentrate for long periods of time under pressure.
1/8 scale 4wd ic nitro onroad rc racing is more for the experienced racer due to the nature of the cars, the difficulty level of driving and the equipment required to run them, set them up correctly and maintain them. These cars do require regular ongoing maintenance and a good technical knowledge of RC racing and car setup in general. The engines require regular tuning and maintenance and due to the nature of the class, a lot of specialised equipment is required to set these cars up, run them and maintain them to keep them operating at a high level so is not recommended for the novice or inexperienced racer.
As with all classes, we run to the NZRCA rules and there is a great group of club members that are more than happy to help and explain things to you if you are interested in 1/8 scale onroad RC racing 4WD IC so pop along to one of our next club meetings to watch and have a chat to one of the club members.
