70 kg 31:1 glider is here to stay?

Gee...that sure explains how a 1-26 won the OLC...with
a lot of very long flights.

Might have something to do with the pilot?

To me this plane is fascinating. I'm amazed by the stall speed of 20 mph. It
sounds like it would be a great idea for soaring around very scenic areas,
where you don't want to rush around all of the time. As well, it would be
comforting to know that if an emergency landing was needed in an
un-inhabitable area, that the crash could be at very slow speed. If it's
durable, easy to assemble/disassemble, and reasonably priced I believe this
would make and excellent club ship.

For soaring, this is it.
New racing class?
Why fly fast when you can fly slower.
What's a rush anyway?
Race slower, cover less ground, easier retrieve.

Somehow, drifting around in a speed-challenged sailplane so I can
crash into trees slowly doesn't have quite so much appeal as flying
quickly cross-country and landing at an airfield!

I would be too - if I believed it.

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!

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? (-:

Looks like fun, but the fact that the best glide occurs at about the
stall speed of my Mosquito suggests that penetration ability will be
limited. Also, given that it takes me twice as long to rig as anybody
else, an advertised rig time of 40 minutes is a big negative.
As a step up from hang gliding or over from 1-26s, it looks good.
Does SH know about this?

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