I heart this thread. Now where is Tom's arch nemesis, the Heartcarve guy?
Tom are you the same Tom that is my friend on myspace? If so I'll send you a instant message cuz I want to try them tele also. I like long skinny skis so these may not work for my real telemark skiing that I and the VT kingdom boyz are keeping alive.
I'm the best DPP in the West.

I gotta say-- opening video looked like .......... heartraxing?

3)Speed testing the rax 230cm comes before flight testing / Günther Foidl, Tyrol.
For big air the landing with rax fins and wings will be very different from landing on conventional skis. Well it`s worth testing. This new feature will also have impact on freeride drops in pow. The Rax is of course a "one way vehicle" like a plane or a boat. So "fackie" backwards will never go as good as with twin tips.
2)"video of hucking cliffs on rax?" Wait a little, Jumpturn. we need some snow on the Rax rocks. RaxSki is still just a snow-going vehicle, it`s not a "glider on the rocks".
1)"post up some close ups of the wings and explain their function" Ok Jumpturn, you are responsible, it was your request.
The physics of the ski control
Think of the ski as an object moving thru the snow medium, mostly on its surface.
The only force that can influence the ski movement is –apart from the gravitation-
the pressure of snow mass acting on different portions of moving ski.
….
The best description of the ski turn is that it is controlled by a number of edge sections interacting with surrounding snow. At any moment of time a section is “turning” the ski, i.e contributing to the resulting torque if and only if it is not parallel to the section’s direction of travel.
…
This knowledge opens the door for new ski inventions. The function of the ski edge can be enhanced or even replaced by short fins or wings cutting the snow surface.

Maybe you should consider the speed riding market?

The "speed skiing market" are those odd eight guys worldwide who can ride faster than 200 km/h on DH skis, Jumpturn.
So the purpose of the whole action will be
1) PR / to show that Rax is good for high speeds
2) scientific / to find out which form of rear fins makes the best self-stabilizing ski.
sweet fancy moses!
We would try our best, bendtheski. Well it depends on the shipping address. We are based in Vienna/Austria.
So tell us your address.
Yeah, the idea to make the ski lighter by cutting off the front part of the ski is a very original one. No comment.
Lets stay in the reality

These things would rock with hammerheads. If anybody has a flat pair, I'll put some tele bindings on, and video the results.
The pic shows our very new model "Joker with wings". These wings are not casted like all others but cut by water jet stream (!) and bent. As a consequence, we cannot mount normal releasable binding on these wings. That is why the complete ski is our lightest RaxSki.
Some testers claim that this is the best Rax of all times. Both for groomers and steep couloirs. This could be great for fully stiffened mountaineering boots to descend couloirs and fairly light to strap to a pack..
I can just say that most people prefer longer skis and think they badly need a secure binding. The customer is the king, isn`t he?
Some maggots are asking how to quantify the performance of an alpine ski? There is a serious modelling of regular shaped ski, reported by Swiss institute (Federolf et al) under the title "Finite element simulation of the ski–snow interaction of an alpine ski in a carved turn" published in Sports Engineering, 2010, Volume 12, Number 3, Page 123. Federolf found that /under normal conditions/ so called "carving ski" cannot really carve but it is wildly skidding aside. The sacred "radius" is just a house number! We are working on testing RaxSkis under equal conditions.
Yet even if you do not trust the experimental physics, you may be able to evaluate some facts when comparing regular ski with the RaxSki:
how easy is a ski turn.
Well, a shorter ski should have an advantage here. Moreover, when you lift its tip, the RaxSki will pivot on its rear fins having the total length of 10cm. 10cm is a little shorter than 160 or 180cm of your regular ski.
how good is the carved turn / we want to keep on carving, to avoid skidding aside
Well, the fins and wings can cut much deeeper than the sharpest ski edge, so holding the curve radius.
can I execute carved turns with radii between 1m and 40m on the same ski
The answer is YES for the RaxSki and NO for any other ski.
can I vary the radius during the execution of a carved turn
The same as above
There is a simple method how to evaluate the tracking of your ski: read your own tracks
Do you really think any other ski would hold the track on this >50° wall ?
I'm going to have to get some of these - surely I will dominate the Pain McSchlonkey this year.
