We were the first to introduce galvanic isolators allowing angle adjustment on our manta kitefoil. this time with the XR1 we push the concept further with a twin conical insert!

Congratulations for the hard work invested into this 2016 production.

A few questions:
1 - In the present catalog, the long running screw feature + twin conical insert does not concern the XR1 which is fitted with galvanic isolators .... the old Manta style system.
Does it mean there will be 2 releases of the XR1 in 2016 ?

2 - Could you tell us more about the carbon fiber winding technology...
For the fuselage, as it is a "long tube", we can imagine that the thickness is constant but for the mast
2.1 Is it the same knitted sleeve all mast long ?
2.2 How many sleeves do you super impose ?
2.3 How do you achieve a thin / sharp trailing edge with this manufacturing process since normally layers are cut ....due to decreasing thickness ... before they reach the TE
2.4 Concave faces cannot be achieved with filament winding technology: do you mold the mast after the knitting and impregnation process to match the concave edges of the mold ?

The XR1 takes back the spacers (galvanic isolators in case of aluminum) design we brought in 2015.
We initially though the single running screw was better and worked a lot on it while keeping our alternative design still in development so we basically made 2 prototypes (actually nearly pre-series models with molds) but in the end decided to forget about it and go for the system we've been successfully using over the last 5 years. However, we greatly improved the build techniques by many factors including introducing the winding process.

both fuselage and masts are winded. this requires more molds and therefore higher investment. the fuselage does not have constant thickness like the mast does. this technique allows to have a continuous fiber that makes the parts impossible to open and stronger.

As for questions 2.1 to 2.4, this is part of our processes and can not be shared but managed... took time...

I noticed a change from the TKF mount to the Ketos KF mount, what is the difference and is there an adapter of some kind so you could use last years board with the new XR1?

Tkf head was straight 20mm wide with 90mm holes spacing while kfbox is 25cm wide and conical with 80cm holes spacing.

If you are interested to order one for you last year board we could sand the box to fit tkf format.

As for holes. We would have to check if we can drill it to tkf spacing but i guess yes.

Such custom work would cost 80 usd though.
