Just in case
its wrong to push a sale........it's not my S6 for sale....I have a Kitfox. Just trying to assist as I surf AFORS daily and saw it advertised (Sad I know)
Re the folding wings, most Kitfox owners use the wingfold system, it's easy and no real problem as long as care is taken. As mentioned use the supports and watch the fuel load. Trailering is slightly more difficult with all that securing etc don't just trust the wing to fuselage rods, tie them together as well.
As an aside, some people advocate towing the Kitfox w/o a trailer if it's a short distance. Don't........you commit road traffic offences such as no tread (trailer tyres now require a min tread depth) and no spats, both of which plod can ticket you for.
