Elvira
is the logical continuation in our series of gliders. Thanks to
it's great wing span, the high aspect ratio and the weight the
model performs considerably better and retains
more momentum than its smaller
predecessors Erwin and ErwinXL. Due to the elegant appearance
we decided to welcome her as first girl in our family.

Modular construction:
The wing of the ErwinXL is identical
with the outer wings of Elvira. This way you can easily convert
from 3m to 4.5m.
Versions:
Apart from
the robust full-carbon construction Elvira will also be built
in a lightweight version. In addition, the model will be
available with electric drive. The luxury of easy starting
and preventing outlandings is an enourmous advantage with
models of this size. And you will hardly feel the
app.
150g additional weight while flying. Aerodynamic
design:
The profile gives the model an excellent dynamic flight characteristic,
the high aspect ratio provides an outstandig distance flight
performance. As a whole Elvira is much easier to be moved
than her smaller relatives. Even in low weather the large model
is easier to be kept in the air. Despite 5.3 kg (plus approximately
150g depending on engine) Elvira can be easily launched in 1-man
operation both on slope and electrically driven.

In
our new video
(youtube, June 2011) you see Elvira in different weather conditions
both as glider and as electrically driven model.
