I am about to build my first scratch MPR (a few kit and scratch LPR's complete) and wanted to make sure I was on track.
I am building a 42"-ish BT-80 rocket with a 24mm mount. I ran a wRASP simulation for the rocket with an F39, which is the max I am planning on running it with and got a result of mach .39, 23G's. I think I am well within the window of 3/32 basswood and TTW fins with no other measures, but wanted to check in with the pro's to see if I am missing something simple. Once sure that this configuration is correct, I'll run the calculations for CG, CP and start the build.
I am using standard Estes type thin BT-80 (36"), a Phoenix nosecone, (4) 15 in^2 clipped delta fins and a 24mm mount with up to an F39 reload. I used the stock cd of .6 in wRASP, as I this seems conservative for this configuration.
Thanks for any help!
