Re: Concept'air 12m Pulsion kite

I changed my 12m 32gr to a new full 27gr and received it 4 days ago at my vacation spot (corsica ! ) where I made 4 rides this week with tt and foil. Detailed impressions : - 20 + gusts : today, side-offshore winds with 20 m trees. I wanted to try. Underestimated the wind that was finally blowing ab...

Re: Flysurfer hard/soft steering line question

The theoretical analysis of foilholio is valuable overall. I only would like to comment the improvement of the backstall , in light wind (but this the principal configuration when backstall is a problem) : when backstall appears in light you first need to decrease AoA , so sheet-out the bar (and oft...

Re: Marginal wind kites ?

Not with all 12m vs 19m models and depends on rider's weight. Under 65 kg it is not so sure : I can start earlier with my 12m than anyone on a s3 19m or sonic or r1v1 for example. However i agree that even at 60kg , for the lighest end indeed 15m is a bit better but for very light and stable kites o...

Re: Marginal wind kites ?

It is useful to put numbers to illustrate but shall be considered as relative comparison and not absolute wind speed. IMO it is not transerable to each one of us when below 6... as there might be up to 3 knots difference with the same wind measured in different ways ... (Experienced between Official...

Re: Is a Flysurfer Soul 18m too much for hydrofoil in light wind?

What you mean with 5-9 knots. If you see people kiting with doors in these conditions, then 12m is sufficient. If you want to kite when everyone else is watching, then 15-18m is needed. I fully agree with that summary. Even with my 60kg I need 15m2 of a powerfull foilkite to reach the lowest end. I...

Re: Marginal wind kites ?

Im still at 8m tube in 12knts phase, but nevertheless my searching for ultimate marginal to decent wind kite is finaly over :) http://kiteforum.com/viewtopic.php?t=2400060&p=1021106 I tried the FRS 12m in light wind back-to-back with pulsion and sonic 2. Light but not marginal. Same appreciated beh...

Re: Repeatable measuring of lift-to-drag ratio, anybody?

Very nice topic that may slide to deep technical arguments. I have been investigating a long time on L/D ratio measures, here is my current conclusion : For a kite , several options on a theoretical point of view : 1- measuring the angle to zenith : The tangant gives you the L/D ratio 2- on the beac...

Re: Flysurfer-specific training?

fernmanus: I think I'm the only one in town here with a 21m and several times I've also been the only person having a solid session on the water (though foil boards are cutting into that! ;) But my low end just doesn't feel low enough -- when it's blowing around 10 kts I know there should be power,...

Re: Pulsion 18m

But it is seen personal wind objective will be lower if kite allows it. I trust much more 9kn wind than 6kn wind and I greatly prefer a self rescue with a LEI in 7kn than with a foil kite in 4kn. That is true but you never choose the wind speed. Hence the real question is : When kitexpert arrives o...
