Various launches of modified Estes kits by Laurie Calvert. These flew on Aerotech Ammonium Perchloride motors such as an E25-7 for the converted 18mm Zinger kits. Needed plastic wings (balsa ripped off, metal too heavy) and extra strength around nose and mount. Alticalc estimates speeds of over 1,000 mph. www.calvertfilm.fsnet.co.uk www.monstersmovie.com

  • 0:23 is it me or did that thing explode?

  • @samosammo123 It flew - what you see getting blasted to the side was the ignitor.

  • Why do brits love rockets? all the videos are brits!

  • @Calvertfilm

    oh ok, ty

  • @satweavers It depends what height it is when going supersoinc. It accels at about 100g, so it wouldn't be very high.

  • @Calvertfilm The multi-stage rockets I've seen have short, finned booster stages not much taller than the motor. I presume this friend-of-a-friend's rocket was similar and not that big, since he launched it out of a city park!

  • @carmium That seems pretty big.

  • @Calvertfilm First, I thought I might mention I DO know the difference between "here" and "hear." I was tired, I suppose.

    I never saw the rocket, although, if I remember correctly, he said it was three-stage. That's about all I recall.

  • @carmium As a matter of interest was your friends rocket the same size as these - 20 inches long, or much bigger?

  • @Calvertfilm Ah! I didn't here anything on the vid, so I wondered.
