WFRCCC 2007 Rules

WFRCCC entry form

WFRCCC 2007 Rules

1. Wheel-driven vehicles only. Vehicles powered by thrust (jet, rocket, propeller, etc.) are not allowed. Turbine power is allowed only if the turbine is used to drive the wheels, not for thrust.

2. Vehicles may be powered by engine(s) or motor(s) of any number and configuration.

3. Vehicles may be any weight, with any chassis configuration and any number of wheels—but the completed vehicle may not exceed 40 inches (1016mm) in length.

4. All vehicles must use commercially available radio gear with a functioning fail-safe system set to apply full brake in the event of signal loss or interference.

5. Vehicles are not required to look like any type of "real" car or truck, but all entries must have some type of 3-dimensional "cockpit area" with windows (clear or painted). It's OK if your car looks like a space ship as long as it appears to have a place for a guy to sit.

6. No sacrificial power systems. Motors or power systems that, by design, are inoperable after a single run are not permitted.

7. Drivers must operate their vehicles from a fixed position. Chase cars are not permitted.

8. Drivers or teams may enter as many cars as they like.

9. For a speed record to count, the vehicle must make a second run and achieve a speed that is within 2% of the record speed. The second run can be made at any point during the event, the runs do not have to be back-to-back.

Entrants will be divided into three classes: Manufacturer Team, Independent Team and Individual.

MANUFACTURER TEAM: entries fielded by RC companies will run in the Manufacturer Team class.

INDEPENDANT TEAM: if the entered vehicle is the collaboration of three or more individuals operating without the support of a manufacturer, it will run in the Independent Team class. High school shop teams, university engineering departments, RC clubs ... this is your class!

INDIVIDUAL: any vehicle entered by a single person will run in the Individual class.

Each vehicle will be given three attempts to make its fastest run. The vehicle with the absolute highest peak speed will be declared the overall winner, and separate awards will be given to the fastest vehicles in the Manufacturer, Independent and Individual classes.

Some questions I've received:

What is the length of the track? It's a full-scale 1/4 mile drag strip. Use as much of the track as you like.

What’s the run up and slow down length See above. You'll have the same shut-down area as a full-size drag car.

Do we need to do 2 runs in either direction? Covered in rules posted above.

Are they one after the other or do you get a period to prepare the car for the 2nd run? Once you're up, you can make more than one run if you want, but once you take the car off the track, it will be the next driver's turn

What happens if you can’t make the 2nd run? Skip your turn, then go in the next opening. If the event runs like it did last year, we'll be following a simple "go when you're ready" system. If you're not ready to go, the next person who IS ready will go. If you're ready after him, you can take the track. It's pretty laid back, we want everyone to get all the track time they can and have a good time.

What constitutes a manufactures team? See post above.

What frequencies can we use for radio equipment? (We don’t have the same ones in Europe and don’t want to get there and have to buy new equipment) Anything you bring should be fine. All radios will be off except for the driver's on the track. I'll bring a spare radio and receiver just in case any driver has an issue.

Are we allowed to modify radio equipment? The rules state "All vehicles must use commercially available radio gear with a functioning fail-safe system set to apply full brake in the event of signal loss or interference." Personal comfort mods (aftermarket wheel or grip, that sort of thing) are ok, but electronic mods are not allowed. I changed my mind, after seeing a few of the radio-mod posts. As long as your "base" radio is an available hobby item, then it's all good.

Are we allowed to boost the output of the transmitter (2.4 ghz is no licensed up to 100 mw but you can get a license for more and boost the signal to 5 watts and get 5 miles range. Can I use this equipment in the USA?) Sorry, need to use out-of-the-box gear.

Can you use other digital frequencies? 900 mhz, 1.2 ghz, 1.4 ghz….. up to 5.8 ghz. These are not available commercially but people are looking at these systems (Me!)
I'll allow this as long as there's no performance advantage.
