Max altitude of 2269 ft. Max velocity of 505 ft./sec. Binder Design Thug with an Aerotech H128W-10 motor.

Big thanks to Toma for being my mentor and guide throughout this process. It was a perfect flight.

If I had more time, I could have jammed a J570 motor in there… and if it survived the transition to Mach 2, it would go 1.5 miles up…. But, much more likely, the paint would burn off and the structure would shred from the supersonic transition. To survive that, I need to wrap the airframe in fiberglass.

  1. …or wrap it in duct tape!

  2. ah, the magical cure-all… Here is the little guy, just after I built it….
    Two Rockets
    He’s been waiting a long time for his first launch…

  3. Are those rotated "J-curves"? 😉

  4. complexify: nice connection. An inverted J-Curve for Mach Number and Velocity…. Something about a rocket blasting off… The only problem is that these ones do not cross above zero…. So, we’ll just call these inverted ’99 vintage J-curves… 😉

    By the way, I am dreaming of jamming a J-size motor in this puppy… If it does not spiral out of control, or burn up at MACH 2, then it will go very, very far from where I launch it. In any case, I figure that I won’t be seeing it again…

  5. Incidentally the classic phrase for burnout dates right back to Von Braun and the early days of rocketry . It is Brennshluss!

  6. What kind of flight computer are you using to get such nice data?

  7. Oh, it’s a rocksim simulation before the flight.

    I just got a G-wiz download from the flight computer for my Firestorm54 launch at BALLS with a J350, but I have not posted it yet (just under Mach, at .96, flew to 10,566 ft, with a max G loading of around 10 g’s). I might wait for the supersonic flight on my K550 motor.
