held in Medina, Ohio from 1982-86. In 1987 the use of the name was given to the Tripoli Rocketry Association (TRA) to use for their annual national high-power sport launch. The launch continues to this day, however, LDRS has never returned to Ohio. North Coast Rocketry was moved to Salt Lake City, Utah in 1992. During this time, NCR branched out into making composite motors based on potassium perchlorate that would produce a pink flame during the burn. North Coast Rocketry was subsequently purchased by Estes Industries' around 1995-1996 and served as Estes' mid/high-power model rocketry division. The NCR motor technology was changed by Estes to the more industry-standard APCP (ammonium-perchlorate) composite propellant). All Estes versions of the NCR models used the F62 Dark Star motors, which emitted a dark black smoke trail. These motors were made specifically for NCR rockets and were slightly smaller in diameter than their competitor's motors. The motor was unique in that it had a molded aft thrust ring on the motor. A G70 motor was announced but never produced. The "North Coast Rocketry by Estes" line of mid-power rocket kits was very popular and command high-prices on the kit collector market today. Especially in-demand is the "Maxi X-Wing" and "Interceptor G" kits. Estes discontinued the NCR line of rocket kits, motors and other products in 2000. Since the brand has been discontinued, when building the kits today, many people modify the motor mounts to use industry-standard 29mm size motors. NCR also sold a heavy duty launch pad, launch controller and relay system. They were also the first to sell rocket electronics, manufactured by John Fleischer of Transolve. These included the first rocket altimeter, a radio tracker, a beeper, a variable timer for staging and recovery system deployment and a strobe light. NCR sold a series of rocketry technical reports, authored by Chris Pearson and Matt Steele, with collaboration of Scott Dixon of Vulcan Systems and John Fleischer of Transolve. These reports were later adopted by the National Association of Rocketry as their technical report series. The Tripoli Rocketry Association also published these same reports in their official monthly publication, the Tripolitian. At NARAM-53 (the National Association of Rocketry's Annual Meet) in Cincinnati in July 2011, Matt Steele (one of the principals of the former North Coast Rocketry) announced that he had sufficient rights to the name and products and that he and his daughter
