SpaceX BFR Flying Model Rocket

thingiverse

Edit 10/19/19: It flies! Beautifully! D12-3 or D12-5 motors recommended. A flyable SpaceX BFR (2017 version). Original file was hollowed out, booster top and bottom sliced and scaled for Estes BT60 size tubing. Couplers added to booster top and bottom. Includes a 3D printed 3/16" launch lug and RSO destruct package for side of the booster. This is about 1/200 scale; it stands 20" tall and should fly very well on D, E or F 24mm motors. Booster has 1/16" slots for through-the-wall fins; these fins MUST be used for the rocket to be stable! I printed mine with 50% infill, both for strength and to put a bit more weight in the nose. The .rkt file can be opened with the trial version of Rocksim: https://www.apogeerockets.com/RockSim/RockSim_Trial or with the free openrocket. Openrocket will not show the wings, however, so take any stability predictions with a grain of salt. If in doubt, add nose weight! See the assembly section for CG location. You can edit this in Tinkercad using the following link: https://www.tinkercad.com/things/2bf1pTvpUYo Other Parts needed: BT-60 tubing, 7.5" long BT-50 tubing, 4" long for motor mount 2 centering rings, .98" ID X 1.5" OD X 1/16" thick (these are smaller OD than standard BT-60 rings because they will be inside the plastic part) I used paper, plywood would also work. Motor hook or motor retention of your choice 4 ea. fins, 3 1/4" X 2" X 1/16", clear polycarbonate or plywood 18" parachute, shock cord Launch lug with 1/8" standoff, or printed launch lug
