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?

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!
