Here is something that taught me about flying. I had purchased a

t=

except
o=
nce when a passenger lied to me about their weight (by 60 Lbs)
while
flying=
a helicopter. I ran out of aft stick on landing, not a big event on a
pav=
ed runway. Anyway back to my story. My plan as always with a
new (to nme)

glider was to take a high tow, do a few turns and stall or two, I was
even

planning on a spin. Well on tow I noticed my new glider (first and
only
ti=
me I purchased a new glider) was rather pitch sensitive, off tow, it
was
al=
l I could do to keep it between 45 knots and 75 knots. Fortunately,
the
da=

abandoned=
my plan of some turns, stalls and maybe a spin. I thought the

with me as I had not been flying fixed wing aircraft much in the

years. I flew for four hours, got a bit better controlling the speed.
I

th=
an I need a bunch more time in this glider and never even
mentioned my
spee=
d control problems to my fellow pilots as I was too embarassed. I
put
abou=

interest=
ing XC flights. With time I got much better at the speed control
(used to
=
fly an all flying tail glider), but I never felt comfortable. Finally I
co=
nfessed my experiences to another pilot and that I thought
somehow I could
=
not fly fixed wing aircraft anymore. Well, this pilot mentioned that it
so=
unded like a CG problem. That had never occurred to me, nor did I
have
any=
experience in this area. Looked at the aircraft logbook again and
had a
W=
&B done. The logs and W&B calculations done by the factory
showed I need
1=
1 lbs of tail weight, the weight from the factory in the tail was 11
kilogr=
ams!!! I seem to remember NASA losing a Mars lander with JPL
using metric
=
calculations and NASA using English system

What did I learn: 1) Always perform a W&B on a glider that is new to
you;
=
2) Never be shy about admitting your flying problems to fellow
pilots;
3)=
do not plan to perform stalls and spins on the very first flight; 4) do
no=
t make excuses for the glider or how it is flying or how you are flying
it,=
tell someone about it! =20

Maybe someone else could add a few comments about what they
would have
done=
and anything else I could learn from this. Also, share your own
story
so=
we might all learn.

I completely agree about thoroughly checking out brand new gliders.
My experiences a

One delivered with a blocked tail tank dump valve and 2 litres of
water in the tail tank.

One with a tailplane rigging knob that was inside the fin at the base
of the rudder by the starboard rudder control horn and interfering
with full right rudder deflection.

One with the TE tube disconnected from the fitting in the fin which
required a hole to be cut in the fin to fix.

And one that had a weld fail on one air brake control rod when I shut the
brakes before it's first flight after delivery! Could have been an
interesting winch launch.

I had every control rod out and in a fabrication shop X ray booth the next
day. It was the only bad one.
