ZN had one on display at the Worlds that I had a peek at. Its typical ZN quality, excellent work on the fuse, wings stab rudder sheeted all very straight. Its a plug in wing, removable canopy which is different than most of their designs which are one peice wings. Unfortunately I did not get a chance to see Marco (the designer) fly it much during the contest. The airfoil is thinner, and wing/stab planform is slightly different (larger, different taper) compared to the Synergy/Enigma/Evolis wings.
