Davinci Gliders / Duet#
Commercial tandem


Easy and fun tandem for commercial pilot

The best is now even better! All advantages of the well known Duet# the new reinforced construction. MJ40 MF for the leading edge and Skytex 38 for the rest of upper surface will withstand thousands of takeoffs and landings.

Pro tandem pilots always ask for easy takeoff. Not an easy task for a rough, heavy duty wing weighting around 8 kg, but we did it! The famous takeoff of the Duet is here again despite the increased mass and durability. This new heavy duty design also incorporates many small improvements compared to the "regular" Duet. New placement of plastic rods for longer lifetime, shorter risers for better ergonomics and other small details which give you more reliability, less risk and much more fun.

Once in the air, this new Duet# also bears all the best from the Duet pedigree. Perfect turn, sweet performance and long brake travel are still here.

i-Vortex Tips (AVT) the DUET# has a very long brake travel.

DUET#: more durability, more fun.
