This is the first flight of my modified Estes Green Eggs. I modified it to also fly on E9 and E12 engines. I did not purchase this kit to launch eggs. Here on an E9-8 and carrying one of my MateCam 808 cameras. I replaced the standard rubber band shock cord with a longer elastic shock cord. Here, recovery is on a Top Flight 18" nylon X-chute. Launch occurred on day two of AAA4 (Adirondacks Air Assault) held each summer in Chestertown, N.Y. This is my longest flight with an onboard camera with a total flight time of 1 min. 21 sec. long!!
