Flysurfer Race Kite

[alexrider]

....
Flysurfers triple depower would also be nice. The range on the Chrono is limited.

IMHO, the triple depower would NOT be nice for a race kite. Speed2s and Speene X-19 were more efficient (better upwind) than Speed3s when the breeze requires to push the bar out. The effect of the triple depower is to reduce the aspect ratio when the kite is depowered, not a good thing for racing.
Jet flaps are also a drag (pun intended!). The mathematical model FS did doesn't fit reality, amongst other reasons because of the disruptive discontinuities alongside the span.
What would definitely be welcome is the ability to control the camber whilst riding. Foils are disadvantaged compared to LEIs on downwind legs because their efficiency doesn't allow them to sit deeper inside the wind window without stalling. An adjusted deeper camber would allow just that.

Have you flown one on a race setup? i.e. Hydrofoil or raceboard? I can go much deeper on a Chrono than an Edge.
Camber adjustment would be the ultimate though! Love to see someone get that right.

I haven't flown one unfortunately. My remark isn't up to date and is based on last generation foils (not designed specifically for race) and comments by top racers of the time (Bruno Sroka, Renaud Madier, Abel Lago...) who admitted that there was no question FS production Speeds were already better upwind than race LEIs, but would lose all the advantage in downwind legs.

More closer lookups of DM's turn. I've done it with (ice) skates but never with skis.



first one at 0:16s and later better visible like from 3:15

Hmmm. I gotta try that....but our snow is melting fast.

I need to do this in my kitebuggy.

So... I'm assuming you need very little wind and the apparent wind in the kite and ski/buggy speed is alot more than the wind so you are able to push a 360 right around the wind window?

VAKE long distance kite racing is going on. Leading teams (at least Upsete & Albatross) seems to be using Sonic-FR by the pictures.
