Basket Case - High Power Rocket

thingiverse

Please note that you need to be either TRA or NAR Level 2 Certified in order to purchase and fly motors big enough to get this rocket off the pad. Don't attempt to build this unless you are. And even then, probably don't. (-; These are STLs from a high power rocket I built and flew on an Aerotech J450. All tubing was LOC 3" cardboard. Main parachute and Drogue parachute sections had one layer of Soller fiberglass sock (3", 10oz or so), the small section that fits into the top of the fincan had 2 layers. All fasteners were #10-32s 4 shear pins on the main side, 2 shear pins on the drogue side to prevent drag separation (all #2-56) - brass shear plates installed on the inside of the tubes to help protect the screws Flight computers are 2 Eggtimer quantums, 4 9V batteries (one for computer and one for deployment for each computer). Switched on with screw switches from Missile Works, mounted in the middle and accessed through the holes in the Av Bay. Av Bay had one 1/4"-20 rod through middle. Has studs for both 1515 and 1010 rail buttons - used 10-32 screws for 1515, 6-32 for 1010 Charge holders and flight computers mounted w/ #4-40s, zip ties for the batteries Please note one side of the av bay and av bay sled is longer than the other - this is to help make sure that the drogue/main sides don't get messed up. Used 1.6 grams FFFFg BP for the main, 1.5g for the drogue. Both were probably overkill. All printed on a CR-10 with Matterhackers Tough PLA, 6-8 solid layers, 100% to 75% infill depending on where. Flew to 2800 feet on a J450, final weight w/o motor was about 5kg. Fin can is 1.25 kg, so a splice is needed.
