D130 Sine wave spar.

[Doc J]

You have to love my sine wave spar, which is 50% the weight of a box spar and much stronger in tension. compression and torsion. As Rod told me, every picture tells a story.

Wow what is the "G" loading equiv?
I am most impressed by the pin point reaction force caused by the small radius chair arms!!!

I have never worked it out for the Dynamics. They are not my models, but they use my Sine Wave Spar with permission.

On the Alpenbrise, it's quite impressive - over 50 G.

So far, the fastest full-up pullout is 361 Kmh - apparently the wings did not even bend.

Cheers,

Doc.

The D80 with sine wave spar has gone over 640 kmh slicing through shear layers every few seconds.

My Ahi can do that

That's nothing, my gentle lady...

The scariest thing is that he's standing on a polished molded wing...with socks.
