A single seat open frame ultralight: a tube and gusset airframe with an exposed seat, a fabric high wing, a pusher engine behind the pilot and a tricycle undercarriage on sprung legs. Dimensions 9.56 x 2.12 x 5.85 m (X x Y x Z). Origin at the footprint centre, resting on y = 0; metres, +Y up, nose toward +Z, wing span and wheel axles along X. Named pivots: aileron-right at (3.58, 1.96, -0.75); aileron-left at (-3.58, 1.96, -0.75); rudder at (0, 1.52, -2.66); elevator at (0, 0.95, -2.54); prop at (0, 0.95, -0.93); wheel-main-right at (0.88, 0.2, -0.07); wheel-main-left at (-0.88, 0.2, -0.07); wheel-nose at (0, 0.17, 1.63). Rigid node-transform clips prop-spin, wheel-roll, aileron-roll, elevator-tilt, rudder-steer drive named nodes on their own pivots. No skinning and no skeleton, so the retraction linkage, rotor flapping and lead-lag, propeller pitch change, the swashplate and wing flex are all deliberately static. Sixteen material palette of airframe white, deep blue, warm red, airfield yellow, bare aluminium, steel grey, charcoal, near black tarmac, light grey concrete, olive and tinted glazing, plus five emissive lighting materials for navigation, strobe, taxiway, threshold and interior lights. Flat colours, no texture maps. Original generic design with no manufacturer, type designation, livery, registration or operator marking. Free 3D model for Unity, Godot, Unreal, three.js and Blender. No collision or navigation data.
