||In April 2006, Tripoli Oklahama will host a Big Daddy Drag Race. This ain't no sissy drag race with a whimpy Estes kit. It is a "run what ya brung" drag race of the baddest Big Daddy's you may ever see. How often do you see the Big Daddy fly with a 54mm J motor?

- Only certified commercially made rocket motors may be used to propel entries. Manufacturers such as: Aerotech, Animal Motor Works, Cessaroni, Ellis Mtn, etc. There is no size limitation, so feel free to pull out your 75mm motors.
- Entries may be constructed of any material that the builder wishes to use with the exception of metals. Refer to Tripoli Safety Code.
- Entry must be painted with no less than two colors of paint. Primer does not count as a color. Remember to somehow identify your rocket. If we have 20 going up, you want to know which one is yours when it is recovered.
- Entry must have a functioning recovery system
- Entries must pass RSO inspection. Since these vehicles will be marginally stable - we will be checkin 'em.
- Winner to be determined by the first rocket that crosses a streamer held by crosspieces behind the pads. The BDDR committee will review video to determine a winner if needed - but we're all weiners.
I've heard several people mention fiberglass and I motor. Word to the wise: If it's gonna pull 40g's off the pad - glass it!
