LS-4 ? What about 1-26 ?

I suspect that all of these drivers will have a similar value irrespective
of whether the glider is a APIS, 1-26 or LS-4. OK ... maybe the material
cost will vary a little but the difference is not going to result in a
glider that is 1/3 or 1/2 cheaper.


YES

The biggest issue with the cost of airplanes is quite simply VOLUME. They
are generally built by hand using relatively crude production techniques and
basic tooling. A modern small automobile is arguably far more complex than
any glider but is costs a LOT less because of the level of automation in the
mass production process and the large number of units sold. If we want
cheaper gliders then we need to find a way to increase the volume of sales.

YES

Certification and design costs would be amortised over more units and
production costs would dramatically reduce (bigger buying power for raw
materials and better tooling / automated production will reduce labour
cost). This is a chicken and egg thing ... you are not going to increase
volume until the price is reduced and you cannot reduce price (which
requires a new business model and significant investment) without the
evidence of the larger sales potential. In essence we are stuck with
expensive gliders unless we can attract some very wealthy individuals to the
sport who share the vision of cheap gliders and are willing to gamble some
of their money, against conventional business wisdom, simply to see if this
vision can be realised without any guarantee of a return.

Which means, more than anything else, that one has to concentrate on one
model and only one, because there is no room for high volume production
of several models. As a consequence, any discussion wether 13m gliders
are better than 15m gliders, wether DG gliders are better than the LS4,
or any such futility may have only one consequence, distract people from
the aim.
