The G1
Tow plane
Certified by the DGAC/FFVV to tow two-seater gliders weighing up to 650kg, the G1 SPYL tow plane reaches 500m in 3min 50s. As Mr Daniel SERRES (flight test pilot) writes in his Trials Report: -« performances in terms of take-off run and climb are equivalent to those of « Rallye 893 » tow planes ».
