#4 cfv4

3D-модель самолёта по картинке. Ракурс — три четверти сверху-спереди, как на референсе
(нос вверх-вправо, одно крыло выше). Фон — голубой, как на картинке. Красный глянцевый
корпус, жёлтые полосы, открытая кабина, винт спереди. Критерий совпадения — силуэт,
пропорции и наличие всех деталей (крылья, хвост, винт, шасси).

Propeller crossed 2-blade with white tips and a red band. Wings noticeably rounded/paddle-shaped, not sharp. Keep silhouette read: crossed wing+fuselage forming an X from this camera. Ground plane not needed; float object centered on blue background."
