Better yet, check your weight. The stall 'speed' depends
on many factors and will vary with weight, configuration,
and g loading. The best way is to stall the glider
in every cofiguration to see what happens, what warning
you get. The speed at which it stalls with you in the
seat is the stall speed. I always recommend to anyone
flying a glider new to them that they carry out a stall
in the landing configuration, wheel down, flaps down
and spoilers/brakes extended so that they recognise
the signs of the approaching stall before it happens
for real.

Thermalling at 48kts in a Discus does not sound that
far out to me but I am on the heavy side.

When you say fast approach what do you call fast? 55kts
is normally enough except in very stong winds or turbulence.

Hi,

i just made my first flights with my new glider: Discus
CS.
I've never flown a Discus before.
One thing i recognized was the hight stall speed.
I wonder if this could be normal, so i'm interested
in your
experiences with this ship.

I flew the glider without water.

With 45 knots i got some warning and with 40 knots
i stalled.
(In the manual they talk about 35 knots).

In thermals i have to fly at min.48 better 51 knots.

Even on landing i had to be real fast for my feelings.

Any suggestions ?

Thanks
Hans
