Hi twfowler; On the subject of home made guided rocketry, and the likelihood that the developed world will eventually be faced with them: The Sunseeker is an electronic marvel designed and built by Dave Mandot. It utilizes a three axis, gyro stabilized, fully proportional sun seeking guidance system. The rocket is constructed of LOC 4 inch airframe tubing and stands 5 feet tall. Empty weight is 10 pounds and fully loaded with an I140 motor lifts off at 13 pounds. ... The Outlaw launch flight of the Sunseeker was a total success. The rocket was launched approximately 45 degrees away from the sun and made a graceful arc into the sun. After the rocket was locked on to the sun, and as velocity increased, some Sidewinder-type "hunting" was evident. This demonstrated the need for AGC (automatic gain control) that turns down control deflections as speed increases. ourworld.compuserve.com Radio-Control Rocket with automatic sun-eye roll holding.
