http://www.artapplewhite.com On 8/20/2011 My brother and I launched our modified Saturn V Rocket on a Aerotech G64 White Lightening 29mm reload. This was the Maiden flight of highly modified Estes kit that was revived after 30 years. The altimeter read 817 feet. This was a 2lb rocket fitted for 38mm motors, so this was just the beginning. Rocket was very stable and capable of taking J-motors.
