Photos of a Christian Derefat designed Vortex UL that I finished building on the weekend.
The sail is 1/2 ounce Icarex with mylar reinforcement at the standoffs only (no Mylar at the spine).
The frame is Skyshark P90 Leading edges and spine, Skyshark 3Pt lower spreaders and 5mm carbon tube upper spreader.
All up with a 10 gram tail weight the kite comes in at 230 grams.
Kite dimensions: 2400mm x 1000mm
I was fortunate enough early in the week to have a few days of about 3 knot winds for a test flight and as you can see by the photo the Vortex fly s quite nicely.
Thanks to Kevin and Michael for supplying the raw materials.
