They are required to support the shape of the kite.
I can buckle my SB no matter how much I pump them up. I still believe that bridle design and sheet in technique matters more.BillyGoatGruff wrote: ↑Tue Nov 24, 2020 8:48 amIf kites are buckling it's most likely due to lack of air pressure (most kites now need around 10psi) and being very flat in design, this flatness causes rapid changes in the angle of attack and canopy flutter. Buy a "C" kite like the Torch, or Vegas, and you will never suffer this issue again. The Naish Torch is still up there with the biggest boosters out there.
Stability when over-powered is better with more struts.Blackened wrote: ↑Tue Nov 24, 2020 12:28 am[..] However, I do feel the 5-strut kites I've flown over my time had better canopy stability and overall better performance when riding overpowered.
As for whaling on the bar, I often muscle the kite around the window because I ride overpowered whenever possible. Do I need to muscle it around? Probably not as much as I do, but it gets me out of situations or kite positions I don't want to be in. Surprisingly how often a good hard loop works to save a bad landing or get yourself out of traffic.
To support the canopy. You can put 5 struts on lower aspect kites, so the number of struts is not the key, but the shape of the kite and bridle it has. Obviously, there are more parameters...but as a general rule...a high AR kite usually needs more struts for freestyle riding. If you lower the number of struts I think it will impact performance in the upper part of wind range unless all you want is to go upwind at a high angle.
5 strut kites are made because a kite with out a center strut sucks - though this is mostly on the light wind relaunch. 1, 3, or 5 struts are ideal for relaunch. 0, 2 and 4 strut kites can sit on their back, and actually be stabilised in this position since there is no "center of canopy" support to tip the kite one way or another.tautologies wrote: ↑Tue Nov 24, 2020 4:27 pmTo support the canopy.

Like the old north designers would be a shit ton of battens and struts on kites that really did not need it to eliminate flutter almost completely. However, if you take that too far you get a heavy kite that is much slower than it has to be. IMO. I am fine getting some resistance here, but my old evo was a dog.
The additional struts strengthen the frame of the kite better, and fuller figured individuals need that.Havre wrote: ↑Tue Nov 24, 2020 11:19 amThe argument in this thread seems to be that it is the shape and not the struts that matter. If so why would anyone design a kite with 5 struts?bigtone667 wrote: ↑Tue Nov 24, 2020 11:03 amDuotone Rebel is a cracking for boosting and hang time. North Dyno was as well. Cabrinha Switchblade was good.
I was struggling to get over 5m and a friend recommended a Rebel. First day I took it out I hit 6m. I then watched a tutorial on jumping and started concentrating on technique. I have now managed a number of jumps over 10m.
I will never go back to a 3 strut kite at 105kg.
Are you saying kite size does not just scale with weight???
Funnily enough, I fly Clouds for foiling and surfing and I fly rebels for boosting.Matteo V wrote: ↑Tue Nov 24, 2020 11:57 pmAre you saying kite size does not just scale with weight???
And to put it plainly, there are strutless kites you could put struts on, but struts are obviously not needed on them.
But there are kites with struts that you could not use at all if you took the all the struts off of (or occasionally key struts only).
