A new version of the mini plane. the first two layers must have a height of 0.12, for greater strength. Bend the rear wings below approx. 45°. The ends of the large wings can also be bent, but it is not a requirement. the tail is inserted into the groove, it can be glued with glue or lightly sealed. Throw the glider upwards, then it flies far, suitable for age-old use even into the wind

Edit: added version from 1pc
