We are the Denver-area chapter of the International Aerobatic Club, a division of the Experimental Aircraft Association. Our members come from all along the Front Range from Ft. Collins to Colorado Springs, as well as from neighboring states. RMAC's goal is safety above all else. We share a love of aerobatic flying, whether for personal enjoyment, the precise demands of competition, or working on the sidelines as judges and support personnel at contests. Our activities fall into three main categories:

  • Competition
  • Recreational flying, including critique and practice days
  • Group meetings and social events

Jim McKinstry has passed
