I am thinking about designing a 29mm minimum diameter phenolic rocket, conical cone, small sleek but effective fined rocket. It will hopely fly on an Ellis mountain H275. I have not simmed it yet but the H275 took my 2.5" diameter 1.5 pound rocket a little over mach so this 29mm rocket should go about 950-1050 MPH, it might even get 1100 MPH. Will public missiles phenlic tubing be able to take the speed, it will be motor mount tubing? Also do nose cones fit into motor mount tubing?
