Hi...
Windfoiler at 160lbs., Naish 122 Hover and 70 mast length.
After 80 days of foiling with stock 1220 front wing, I bought a kite 600 wing and paired it with stock fuze and rear wing.
11-19 knot winds, REALLY stable, much more than with 1220 wing and smaller sails.
Moved setup forwards 2" to accommodate higher aspect front wing.
So....that setup is very stable, I wonder if it's due to the bigger rear wing [stock for 1220 front wing]. I left the kite setup rear wing in the van because it hums like a banshee and was unstable across the wind spectrum.
So, bigger rear for stability?
