One of the favorite KOSMO events each year is drag racing. This usually takes place during our late summer Final Frontier Fun Fly. The KOSMO style drag racing rules are simple (but different than the NAR rules):
- Your rockets must meet the minimum requirements for the class (See table below).
- Races are conducted in heats of two rockets at a time. Pairing is decided by drawing names from a hat. In the event of an odd number of participants, single "runs" must still be flown.
- Contestant may only use one model per class.
- Three points are awarded for each run. One for first off the pad, one for the highest altitude, and one for the first safely down. The flyer getting the most points wins that heat.
The following table includes the minimum specifications for all of the classes.
Note: At the 2010 Final Frontier Fun Fly we will officially have drag races in the Junior Drag, Top Gas, and Funny Car classes. You are welcome to bring others and have "grudge" matches with each other if you wish.
| Name | Motor Impulse |
Minimum Body Tube Diameter (inches) |
|---|---|---|
| Junior Drag | A | .75 |
| Stock | B | 1.00 |
| Pro Stock | C | 1.25 |
| Top Gas | 20n-s (D) | 1.5 |
| Top Fuel | E | 2.5 |
| Funny Car (Goony) | A | 1.5 - 1.75 |
The "Top Gas" class is a 20 newton-second class. This means that your total motors must equal 20 n-s in impulse. Specifically, your rocket can use 2 "C" motors or 1 "D" motor.
The "Gooney" class must be at least 1.5 inches in diameter, but no more than 1.75 inches. The total body length, including nose cone should be no longer than 11 inches. A single "A" motor is allowed on the Gooney class. A good starting point would be the Estes Mini Bertha. A "whimsical" paint job is encouraged.
On all of the "racing" classes, a racing paint theme is encouraged.
