Erwin XL slope is a robust funflyer fully built in carbon with a good relation between price and performance. He is perfectly suited for hard use on slope.

For more technical details look into our building instruction (pdf-file)
For more details of the model read the review of Aufwind-magazine (German).

Erwin XL slope is - as the two related models Erwin and Elvira - manufactured in a special building method without sandwich. The outer skin is made of robust 160g carbon. Because of that, the surface of wing and V-tail is extremely durable and the model is perfectly suited for extreme conditions.
Standard colours (please click):
RAL 2004
RAL 3020
RAL 9016
RAL 6018
RAL 5012



Since June 2018 our Erwin XL is delivered with a new design.
(see also big picture above)

Upper side with paint in 2 colours,
underside in visible carbon with white bars.

Wing and V-tail are built with a stiff outer shell without CFR-sandwich-construction.

Often transport and landings in rough terrain don't create permanent dents on the wing as this is the case with sandwich-constructions. All that remains are possibly some scratches.

The wingtips were optimized for good-natured flying characteristics despite high wingload.
Precise and simple mounting of the levers by prefabricated recess,
shaped control covers
The servo boxes were designed for all standard servos, specifically: Futaba S3150, with mounting frame
Two wing-connectors  

Easy system for ballast with steel stabs
(shown on an older version with a different wing end)

All rudders are mounted with silicone.
Rudder gap is closed on wing and V-tail.
Carbon covers for servos are enclosed in the kit.
In contrast to older versions, we put a canopy on the fuselage cone for better access to accus, servos. The servos for controlling the V-tail are situated in the fuselage and hinged with pushrods.
An appropriate servo board is supplied.
