Which GRP single-seater has the lowest cockpit weight?

The mother of a teenage flight club member made a polstered cushion with
plummet sheets inside. They say it weights 20 kg (about 40lbs). It was
hard for the boy to carry it to the plane, but he managed it. He
additionally needs the Ballast Weights near the pedals.

A friend of mine, who had similar problem, used to carry a little bag filled
with sand (made by her mother;-), which placed under her...you know where,
added some extra lbs (even 20 ). One thing you should do if you use this
solution is to make sure, that the sand never gets out into the cockpit - it
may cause seizing of some mechanisms and it can end badly. Better if you
raplace sand with some stones (less comfortable, but more safety)

Ok folks, I think I've read in just about every "How to fly
sailplanes" book including those by Piggott and Knauff that you don't
want to add ballast using an "under the deriere´ (never could do
French)" type. If you are going to add ballast make sure it is
attached to the airframe and not held on by your butt! I think this is
in a couple of POH's I've read also.

Bob (who unfortunately does not have a need for ballast)

OK, then use it with an 5 point harness and it should be safe. Thx for
remembering, I forgot to add this to my satement before.

I don't think that is the point, Andreas... The problem is that you
then have a substantial weight that will be free to mash against you if
you hit turbulence or an accident, pinning you between the belts and a
pretty heavy mass.

Most of the girls in my club need about the same amount of lead
weight. Usually the boys carry the weight around for them...

Sex sells.

Girls?

In a glider club?

How'd you manage *that*? Our ratio is on the order of 60:1. That's the
female to male ratio, not the glide ratio!

Though it is usually hard to distinguish them from the guys there áre
girls who fly. Whether it's the gliding or the huge number of male
that attracts them isn't too sure...

Our club members who need ballast often use a lead cushion tied/clipped
to the seat belt attachment points. By definition, these are strong
enough to take both weights. The difficulty is the integrity of the
attachments at the cushion end.

Sorry to here that. The females at our club are easy to identify.

PW-5 as an One Class Design by definition must acomodate the pilots in
widest range of weights. The gross weight of all mashines at the grid
must be the same, adjusted to the heaviest pilot in the competition.
It has two system of balasts. Four removable weights in tail, which
you add when the (pilots + parachute) is over 167 lbs as far as to
231 lbs. We also have eight small compartments under the removable
pilots sit pan, where you can put eight 10 lbs bags of lead shot. With
all begs in place firmly secured and no tail balast you could be as
light as 81 lbs with a parachute. Preatty wide range and very
safe. :-)
