Shopping for a motor. I'm looking at a CSI I175-White for the maiden flight. It seems that offwegorocketry is offering the Cesaroni free case deal, and an I motor will get me a 3-grain. With $50 saved, I plan also on getting a couple spacers and a drill-out tool. No rear closure needed on a 38pro, I think. Do CSIs have forward closures? I was sure they didn't but this is like a last-minute sanity check. Won't be placing the order tonight.
Running the flight test on my spreadsheet, the rocket should reach a max velocity of 283 or less m/s (the sheet doesn't calculate anything special for near Mach) and reach an altitude close to 3000ft. Too much for a maiden? I haven't seen too much of the flying field but will look up some vids to get a better inspection. With a flight ceiling of 10,000, I don't think I'll lose the rocket, and I won't launch if it's windy.
Max-V (and prolly Max-Q as well) is 2.4 sec into flight with apogee around 10s later, so I'll need to drill 4 sec off the delay charge, will recheck before I go.
I'm curious if any other manufacturers are running the special, or if there is any other hardware I may have overlooked, as this is my first HPR launch. Will be contacting the club as well with a couple questions about their procedures, field, etc. And I'll have to save up, and COVID-19 possibly interfering. Planning to launch on the 3rd Saturday of next month or possibly the following month.
Can you take your Lvl 2 written test after the flight (TRA) or do you need to wait for your Cert to be sent in? Once you pass the test, how long is that good before you can cert L2? Or is it better to take the test prior to the L2 flight? Kind of excited about getting into bigger motors once I have all the electronics figured out and purchased for higher altitude flights.
