Diana-2 and overall performance discussion

I do not agree. Stefano is leading by just 2.3% over # 2 Leigh Wells
in an ASG29. I'm sure that the Diana-2 advantage over the contest has
been much more than just 2.3%. If he had been flying an ASG29, I am
convinced he would not be leading as the ASG29 suffers much more than
2.3% against the Diana-2.

Cockpit size may be a factor in the USA, but in the rest of the world,
most people are still reasonably sized.

I agree on that. Americans are over sized and need to consider that
more than anyone else. However, the American market is small compared
to the rest of the world anyway. It would be interesting to study
physical fitness Vs. placing at a World soaring contest. I can not
remember grossly overweight pilots ever placing in the top 3. I think
there is a correlation and cause and effect there. Sorry but I think
true.

Reichman wrote is his book that fitness is a very important element of
success in competition soaring.

I suggest you buy one and come out and kick our butts with the
overwhelming performance advantage.
But- don't crash it.
Perspective- I had a long exchange with Gerhard Waibel when he was
doing the ASW-28. I wanted a smaller wing with higher aspect ratio. He
went slightly the other way. His practical explanation was that he
wasn't designing the product only for me as a racer, but that it had
to work for many users and be usable in a club environment in order to
be a viable product.
It could also not compromise the level of safety established.
I have 2 gliders in my shop now where the pilots likely would have
been seriuosly injured if the gliders they flew did not have this
important attribute. This is not possible without some additional
structural weight.
It also must be repairable using techniques available in existing
repair shops. The JS1 guys paid a lot of attention to this important
point.
Owner needs to be confident he will be able to get parts and support.
Buying my next racing glider depends on being able to sell the one I
have now. I doubt there are more than a handful of folks that compete
that aren't in the same situation.
The Dianna 2 is a remarkable machine, but my personal evaluation was,
and is, that it does not measure up to other options in the areas
other than performance.
FWIW
