I first saw a Binder Jaguar at a ROC launch back in 1997 or 1998. I remember it was on Pad 39A (our club's big rail, built by Leslie Seiders) and took up nearly the entire length of the rail, and flew really nicely on a White Lightning motor. I found a marked-down Jaguar kit in one of the bins at RocketSilo and picked it up to build. The airframe has a layer of 6 oz glass to stiffen it and make finishing easier, and there is a dual-deploy altimeter bay in the center section of the rocket.

Flights

Event: Perchlorathon May 2005

Date: May 21st, 2005

Motor: AT I218

Apogee: 1,900 ft

The first flight for the day was my Jaguar. In an attempt to color-coordinate (and make Kathy Gilliand proud), the red rocket used an AT I218 Redline motor, with red tubular nylon and a red-and-white PML parachute. Prep went quickly, using only apogee deployment, and the rocket was on the pad in no time. The boost was fast with a significant wiggle - fins are a bit too small, I think - but the major problem developed about 1 second after burnout, when the delay burned through and ejected the parachute as the rocket was still traveling upwards at a good clip. This was an old reload, and I'm betting that the burning rate catalyst migrated from the propellant into the delay. The result was a 2" zipper down the side of the rocket - oh well.

Event: Perchlorathon June 2004

Date: June 19th, 2004

Motor: Kosdon I130

Apogee: 5,460 ft

For the first flight of the Jaguar, I wanted to push it high, but not fast. The c-slot load for the 640 case seemed to be just the ticket. Prep was easy, using the spacious altimeter bay, and the rocket was quickly on the pad with an igniter installed. A well-known (infamous, even) flyer kept telling me how the motor was going to blow up since it was a c-slot; I think he was just bitter that I like Frank's motors better than his. At zero, the rocket ignited and lifted smartly off the rail. It wagged its tail a few times on the way up, and coasted up to apogee. The drogue appeared waaaaay up there, and the rocket fell for a long time to 1000 feet, where the main deployed. Good first flight!

I like to design, build, and fly rockets. PostFlight started as a project to help me keep track of them. Now I've opened it up so you can follow along, too.
