My Sledgehammer weighed in at 56 lbs.
An imposing 9 feet tall… with wings, and a M1675 motor
and RF transmitter, festooned with video cameras, two logging flight computers, and a cool Rousetech CD-3 gas ejection system for the parachute deployment (no charring of the fabric).

The pink plume propellant was developed in Canada for the ladies.

It will take a bit of time for me to compile the best video segments from the four cameras. It was a perfect flight, with a powerful roar going a mile straight up.

    Max altitude was only a mile?

  8. thanks y’all. She sure is pretty in pink.

    [http://www.flickr.com/photos/79289632@N00] – Well, she’s quite heavy and phat. I was trying to revisit the mile high club. Computer logged 5,120 ft., so pretty close!

    I just read in the LUNAR flight report:
    "At the heavy end, Steve Jurvetson’s ‘Sledgehammer’ flying on an M1675 made for the most outrageous “Mile High Wall” flight we’ve had yet. How do you keep an “M” motor rocket down to only a mile? His altimeter told us his flight to 5,120 feet was pretty much on the money."

  9. Pretty in Pink…congrats on a great flight!

  10. Video posted anywhere yet?

  11. not yet – been too busy to pull it together. Maybe this weekend.

    Oh, the propellant even came in pretty pink boxes…
