SpaceX BFR Flying Model Rocket

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:

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.
