    Was there supposed to be a longer burn on that motor?

    That was launched on a CTI O 25000 with a 1.3 second burn time, iirc.

    Correct. O25000 motor, 1.25sec burn time. Rocket mass 400kg. Altitude 624'. Recovery was was controlled by DTMF encoded radio signal. Primary deployment was high-pressure (20bar and 30bar) pneumatic separation systems. Backup for that was three RRC3 altimeters triggering the same pneumatics. Airbags were used to throw the chutes out of their bays once separated, again using the RRC3 units.

    Construction of this sounds similar to what you had in mind. It was detailed in Sport Rocketry a few issues back. Should upscale fine. You'll need a lot of nose weight. Click image for larger version.

    It's almost like someone posted those very same links earlier in the thread...

    Not to be petty but one reason threads get so long - folks don't read through the posts before adding their own and add a lot of duplicate information.

    Vatsaas brothers used to have some unique rockets but I can't find their site anymore so I suspect they moved on. That's one of their rockets you mention above.
    It was a take off of the fieud that Prince had with Sony. Kurt

    If I remember right they had stability troubles with that shape. As the speed increased the airflow would detach from the rocket where it decreased in diameter casing the fins to loose there airflow and the rocket would tumble.

    Need the fins to stick out beyond the rocket body to be safe.
