The TrickTail sul
I do think this is a std sail, but I framed it as an sul. Flys very well and very early .. in about 2-3 km/h (1-2 MLH).
Actually I framed it more like an ul, but without the upper spreader. P100 (upper leading edge and keel) and PT3 (lower spreader and lower leading edge).
If nothing else flies, this one is worth a try. I can remember my friend Steve flying these quite nicely indoors!
