Hello All,
The discussion on the recent thread about minimum-cost model rocket kits for schools and youth groups, especially those in low-income areas (see:
http://www.oldrocketforum.com/showt...10&page=1&pp=10 ) raises another possibility, for a "new" motor.
To achieve impressive altitudes with 13 mm mini motors, the models could be minimum-diameter rockets not unlike the Aerospace Speciality Products 13 mm Streamer Duration and Parachute Duration kits (see:
http://www.asp-rocketry.com/store/c...fm?Category=176 ), although equipped with standard sport streamers. Depending on the rockets' size and mass, even BT-20/#7 size models could perform well on 13 mm motors.
Such rockets (especially minimum-diameter ones) could get the maximum altitude out of the Estes A3-6T mini motor (see:
http://www.ninfinger.org/rockets/ca...74/74est54.html ). Also, if Estes put the A3-6T back into production, it would greatly improve the performance capabilities of their new two-stage mini motor powered kits. As a bonus, this motor would again be available to competition flyers.
