There is an aircraft which I cannot identify:
- the sticker on the propeller leads to a propeller manifacturer called Avia
- guess its a double engine plane with retractable landing gears
- the picture on the CDs are invertet so I inverted the colors
- guess it's a combustion engine, not a jet
- the vent slots are pretty similar to Zlin planes but could not find a model which fits to the pictures
Solved: it's an Let L-200 Morava, thanks for your answers!
