FlySim
A 3D drone & fixed-wing flight simulator with real-time OpenGL rendering, realistic aerodynamics, and a Qt control panel. Supports keyboard, mouse, and the WFLY ET16S RC transmitter over USB HID.
Features
- 12 multicopter models (quad / hexa / octo): GEPRC Mark5, iFlight, TBS, Tarot 680 Pro / T18 / T960, E616P, DJI Agras T50, DJI M600 Pro, DJI F450 — each built to its real wheelbase and frame dimensions
- 3 fixed-wing aircraft: trainer, Eclipson Model A, sport plane, with a proper aerodynamic model (angle of attack, lift, drag, stall)
- Power-system builder: 12 motors, 39 propellers (3"→54", incl. 3011), 12 batteries — real-time payload capacity & endurance via actuator-disc theory
- Terrain system: flat, fractal-noise random DEM, load DEM (PNG/ASC/GeoTIFF), and satellite imagery (ESRI World Imagery), with terrain-aware collision
- Airflow visualization: particle streamlines, rotor downwash, wind arrows
- Atmosphere: temperature / pressure / humidity / CO₂ → real-time air density, viscosity, speed of sound (ideal-gas law + Sutherland's law)
- Qt control panel (
flysim --qt): tabbed menu, model selection, power system, environment, and camera zoom - Realistic physics: alternating motor spin (CW/CCW), momentum-theory hover power, per-motor thrust mixing, Verlet rope + payload
- Live RC panel (channels CH1–CH4 in PWM, RSSI signal strength)

WFLY ET16S (HID, Mode 2)
Throttle = left stick Y, Yaw = left stick X, Pitch = right stick Y, Roll = right stick X. Auto-detected via pygame joystick.
Coordinate system
- North = -Z, East = +X, Up = +Y
- yaw = 0 faces North; yaw increases clockwise (top view)
