ASH25 out to kill you?

Thanks for posting that. I only fly a (15m) Standard Libelle, but learned
stuff from the careful explanations in this piece. I've saved a copy for
future reference.

Is this common place in the glider world?

I think its a logical extension of experience flying powered aircraft,
simply because all composite gliders have much less drag, much longer
spans and higher aspect ratios. As a result, they may accelerate faster
in a dive, exhibit much stronger adverse yaw effects, and may flutter
more easily than a typical powered plane that operated in a similar speed
range.

But what do I know? I've only flown two powered plane, my club's Scheibe
SF-25 TMG and a DH Tiger Moth, since I've been a glider pilot. I found
both very easy to fly, especially the Tiger.

Clearly the article talks about unusual attitude recoveries. Not normal flying.

Totally learning a lot from this article. Learning to fly a glider makes you a way better pilot than just flying Cessnas and pipers around.

Keeping that article in my library. Lots very good information there.

Interesting read in the link......longest span I have flown is ASK-21 and ASG-29.

Towing behind the car, yes... But in the air don't let it intimidate you.
To me the ASH25 handles just like an ASW20.
Never spun one, but haven't tried in a 20 either.

Will gladly accept the give-away ASH25 after the one Steve gets.

I have and recovery is quite benign - recovery in 1/4 turn though 300 ft
lower and doing 80 kts from a 45-50 kt thermal turn with zero flaps
(position 3).

I don't know whether this was specific to my early example (s/n 34), but
it twice departed without warning from a 40 degree banked thermal term at
around 45 kts with zero flap selected. I suspect in-thermal turbulence
had a hand in that because the 2nd time it happened, I tried and failed
to provoke a similar departure in late afternoon air after I finished the
task.

Martin,
Why are you thermalling in zero flaps? I always went to first positive flap position when thermalling the ASH-25 and never had a departure or even drop a wing.

I did that primarily because I preferred the glider's feel in position 3.
It always felt too stately in thermal flap (4) and didn't seem to climb
that much better, except in very weak conditions.
