70 kg 31:1 glider is here to stay?

Though this ship looks like a hoot to fly, I have my
doubts whether this ship could be aerotowed by conventional
towplanes. __Mike

Why fly fast when you can fly slower.
What's a rush anyway?
Race slower, cover less ground, easier retrieve.

Depends on pocketbook, eh? Some can afford a PW-5 and some ASH25M
Enjoyment of each can be equal.



And others like mysef and many members of my club can't afford anything,
or wouldn't have any money for paying for launches after buying a PW-5,
but our club can afford 4 LS4, 2 Pégases, 1 ASW24, 2 Discus, 2 LS6 (17.5
& 18m), so why would we even consider buying a PW-5?

To compete in the World Class competitions?


This is the only reason for which the 5 PW-5 registered now in France were
bought. No, only 4 of them, one was won as the prize for the 1st World Air
Games. The 2 winners of the 2 first internationnal World Class competitions,
Fred Hoyeau and Julien Henry then reverted to the old FAI classes.

As many of us, I am not a competitor, so this would not be a good reason for
me, maybe I will try some day, but anyway using a club glider, so not in the
World Class.

Of course here is the latest in FL sailplanes - not
even in production yet...

The point is that no more than 1/10 if not 1/100 members of
our clubs wants to compete. ****ing contests are not our most precious
asset, we old europeans ...

I believe it Bob,
All of the the gliders iIve ever flown as far as I can remember have been
fully stalled at 20 mph. Most have started somewhere between 40 and 50
though.
Cheers!

Good points.

Let me think back... there was a day when the 2-33 sufficiently
inspired me. And not long after when the 1-26 was as pretty and nimble
as you could want a glider to be. There were glass gliders on the
field, but they didn't diminish my interest in those gliders I had
access to.

Let's be clear about something... real pilots need to fly. When I
decided I wanted to fly the best, I changed my career goals and found
a way to afford it, rather than whining about a lack of acceptably
cheap, aesthetically pleasing, high performance sailplanes.

Whining about what I don't have seems to me an exercise in futility.
Even worse, whining about other people who are honestly trying to keep
others from whining... well, it's a sad thing, indeed. If you are a
real pilot, as opposed to someone who just likes to tell his friends
he's a pilot, you'll fly what you can afford and love it. Or you'll
find a way to affort your dreams. All the better if someone is
inspired to find you a better price/performance ratio. Who cares what
it looks like?

The numbers quoted by manufacturers for empty weight, stall speed, minimum
sink, and yes, especially L/D, are purely marketing numbers and mostly
fiction.

There are aircraft that if you used 1.3 VSO for approach calculated by the
advertised stall speed you would never make it to the runway!

Also note that the stall speeds given by the manufacturers are usually given
at the minimum possible (or impossible) mass. Then again, I weigh 85
kilos...

So, Bob, are you going to change this state of affairs with the HP-24, and
say so loudly, or continue to add the customary percentage? (-:

To paraphrase, "There are lies, damn lies, and specifications". Caveat
Emptor.

On the other hand, traditional soaring is dying all over the world
