This is one that I just wanted to see if I could get a F-motor to go mach. Built from a Estes BT-50 tube with a length of 18" And coming in @ 4oz. Its got two layers of 2oz glass cloth. And a motor retainer I turned myself. Just to keep from kicking motors. On a F-72-15 it will go 830MPH. And 56G's will do 2600' in 3seconds. On a E-18 it would go 3600' surface mounted plywood fins. That I airfoiled on the table saw. And glassed over with 6oz. cloth. Should be a real fun rocket to fly on a clear day.photos.yahoo.com/rockets_r_us2
