Scheduled Things ---------------- Winterfest, Summerfest, and Octoberfest are large meets of the Tripoli Rocketry Association. You can expect at least 100 people (and as many as 200) flying everything from A engines in Estes rockets (not too many) to K and L engines in home-built rockets (e.g., a full-scale AMRAAM). Many rockets will use H, I, and J class motors. These meets are the perfect opportunity to get exposed to amateur high-power rocketry.
