The entire F-one mechanical solution is a nightmare. ...
I have to disagree...IMO its brilliant!
..
As an additional info. Fone have a complete new plug and play system for 2019.
Also heard that story about rubber hammer+fone, but for sure the old version.
The basic problem I see which does not hit Fone alone, but nearly all manufacturer ... but on the end pretty much Fone:
In respect to compatibility a few years ago a conection system designed was designed, when people were happy to ride straight and wings have been small with spans, just for kiting under 60 cm. And that is what the conection was designed, maybe calculated, but at least was tested for.
Today it is normal to use wings with spans over 60 cm and there are a lot more people riding on a high level, hard on the edge, fast, jumping ... some times in combination with big wings.
Till now with my 63 kg I slightly cracked (repairable with effort) 3 foils: one old carbon Zeeko Makaira and two times old Levitaz.
Now I start using GONG, but not started jumping yet.
I think for me latest reinforced Levitaz will be stable till their biggest wings with about 63 cm span by using a clammed steel to carbon conection of 24 mm widness and 60 mm of length.
GONG uses in his latest design a non conical, but apart from that similar construction as Fone for kitefoil with flat areas 4 times 18 mm widness and 90 mm of length.
I also like the basic idea from fone of one screw on the nose, where it doesn't disturb, also a lot.
My point is, even if Fone switched to stronger material, the widness of the inner flat areas in the conection, that can transport torsional load looks just very tiny (any data?) to an engineer, also if I haven't calculated nothing, but the physical law of lever just does not know any mercy at that point.
Is there anybody who is jumping a lot with fone and has a video to show what this means.
