Getting my Level 3 just wasn't difficult enough...

A few of us were sitting around lunch one day, discussing another "to 100K" project, when we decided "Hey, we can do that!"
 
Then Cliff asked Wedge to borrow a "P" motor, and he agreed.  The James turned a nozzle, and started doing Burnsim work.  Then I started using RockSim and WRASP to see how high this would go.  Then we got a fin can for the sustainer.  Then I ordered $1300 worth of stuff from Performance Rocketry, and eventually it showed up - including an ISC that's to die for.
 
Well, we're started, and it's a huge, exciting project.  A truly scary and awesome project.
 
We've designed the beast.
 
We've done simulations.

And, we've tested one of the motors:

N2900 Test at Black Rock, Aeronaut 2006. Exciting!

We did a second test.  It worked much like the first!
 
We did a third test.  That failed as well!

3rd N-class Motor Test, at the Rocket Ranch, March 2007

But we have successfully burned the P8800 motor!
 
Update 05/28/08 -  At Dairy Aire (Saturday May 17th), we flew the sustainer on a K458 to 4500 feet, and recovered without error!!
