I don't care what colour my next REV is as long as it will fly in 1 mph , or thereabouts, the 3mph for the SUL would be a luxury, i find myself trying to fly in less than that most of time.
yes I've got SUL with RACE rods and its still hard work, an indoor which is twitchy, and a Flic style with no vent which is ok.
This winter i will have a go at a simple 2 piece sail in lightest materials i can find
The low wind version of a REV , would be a seller.
