Finished CAD model: (now on to 3D printing...) [Finished: 3/16/22]
(there are still a few parts that need to be designed, but other than that, the design is DONE)
those faint blue lines are the servo pushrod routes for the elevator and rudders, as both servos are inside the fuselage (so the plane looks pretty)
tail section, you can see the internal geodesic pattern as well as the lightening holes
elevator and rudder servos and their respective mounts (more lightening holes included)
Bonus: here's a CFD simulation I did on the air intakes a while ago
tested w/ air velocity = 17m/s
The design is way outdated, part of the fuselage was removed to improve airflow.
The esc will be placed inside the underside air duct, as the airflow is much greater than the upper air duct.
