Einar Ek built this formation of four, using an article from 1978 as his inspiration.
Wing span: 130 cm, Motor: OS25FSR.
The evening sun bothers Erik a bit, so he will wait until it is almost set (!)
In the air, the illusion is total.
Top Gun pilots, keeping their aircraft in position through loops and rolls..amazing !
The spectators cheer Erik after perfect landing. Happy pilot !
