Binding and Fin Placement Question

[TDET]

Last week we took my sons binding off his 66 A3. His binding is a radar strada. When we put it back on we accidentally forgot to put the two center screws in. His last 3 nights he has done 3 pb's at 36 mph. He has also has a few pb's for wipeouts in the process because the ski skips out from under him at the apex of the turn. Tonight we noticed that the binding has moved completely forward because of the missing center screws. He has done better with the binding forward but I don't know what to do with the fin to keep the ski from skipping out. Any ideas?

Thanks, Tom

the schnitz tuning guide says to move the bindings back, increase fin depth, or move the fin forward to fix tail lifting and or blow out. so one of the last two if your not going to move the bindings.

[KcSwerver]

From what I was readying I think he needs a fix for blowing the tail WHEN he moves bindings forward. (Less pressure on the tail could cause it to pop out)

[mwetskier]

@KcSwerver - right. the schnitz tuning guide gives a bunch of fixes for any given problem and the 3 i listed are all for tail blowing out so he would want to use 1 of the other 2 and not move the bindings back.

[KcSwerver]

Got it. Hasty reading isn't always good reading. Understand what you are saying now

I would set the bindings to the stock recommendation and verify that your fin is also set to stock. Then if you want you can experiment with moving the bindings forward small increments and see how he likes it. The fact he is setting PB's for skiing AND wipeouts at the accidental binding placement would have me concerned. Chasing a fin setting to optimize an accidental binding placement seems like a hard way to go. Start with what previously worked and make small adjustments to try and make it better. Then again maybe you have stumbled upon some magical top secret settings.

mwetskier,

Where did you find Schnitz's guide? He used to have it on his front page, but I looked for it recently and couldn't find it. The "problem-fix" section was pretty good.

Typically, you move the fin forward if you move the bindings forward and move fin back if you move the bindings back.

[MrJones]

Found it.

@TDET It sounds like your son likes an easier turning ski but the big move forward was too much for that ski. Try moving back to stock binding placement or forward one hole (properly measured, not necessarily the middle hole of the binding plate). Then use the fin to achieve an easier turning setup. First make sure the fin is properly set to factory settings. After skiing with a confirmed factory setup, if easier turning would still help, more info/video will be needed before fin recommendations can be suggested.

Could be form as well. If he leans back a little as the norm, he would benefit from more ski in the water, so set the bindings to stock and make sure he isn't skiing off the tail. Then you can make adjustments to the fin to get more tip in the water. Add length or take away depth, or move fin back, all would be in that general direction..

@MrJones can you post a link to the Schnitz guide I had a hard time finding it also.

[Deanoski]

He makes you pay for it now. it not free info. I printed out a copy years ago. use it from time to time. lots of info in the tuning guide

[TDET]

Thanks all, If the weather holds we will go out tonight with stock fin settings but with the binding a hole forward from stock. I'll post a video of the results.

[mwetskier]

the internet is forever you just have to know how and where to look.

scroll down to bout half way down where it says 'rewrite of clues 6/18/2004'.

@mwetskier I couldn't get that to come up.

 

I would be willing to pay something for the guide like around $10 but he was asking big coin for it last time I looked.
