ELVIRA


After the light version of 3m-Erwin XL has thoroughly convinced, we expand our program and are pleased to introduce another lightweight-glider:

Elvira ultralight is an ultra light thermal floater with DLG feeling in XXL format. In addition, we offer the model also as an electric version.

Elvira ultralight combines the positive features of our 4.5-meter slope model Elvira and 3-meter light glider Erwin XL ultralight in one model:

Due to the large wing span and the high aspect ratio, the XXL-model has a considerable distance flight performance, the airfoil gives the model an excellent dynamic, especially when the model is fully ballasted.

Thanks to the low wing loading, the model also has fantastically simple circling properties with excellent climbing values. Due to the size Elvira ultralight can be controlled easily and uncritically. Even in weak weather the large model can easily be kept in the air.

The model has an extraordinary range of applications as the wing loading can be varied over a wide range.

Elvira ultralight is designed for slope and airflields. The model can be wonderfully launched with rubber high start. The electric version allows particularly simple recreational fun and is suitable for competitions such as RCMS.

NEW: Also available as CARBON-version with 39g non crimp carbon as outer skin!

The servos für controlling the V-tail are situated in the V-tail.

The wing consists of three parts, a middle part and 2 outer wings. A plug is let into the root ribs for electrical connection when putting the wing parts together.
