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.

Get a first impression in this video (youtube, January 2011) showing Elviras first flights.
In our new video (youtube, June 2011) you see Elvira in different weather conditions both as glider and as electrically driven model.
