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 Internet search Calvertfilm
