Erwin XL 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 new building instruction (pdf-file 0,5MB)
For more details of the model read the review of Aufwind-magazine (German).


NEW:
Now in a revised edition
- less building time
- improved aerodynamic on the wingtip
- easy access to the radio control
- fewer lead in the fuselage nose
Standard colours (please click):

Details:

NEW:
We put a canopy on the fuselage cone for better access to accus, servos. The servos für controlling the V-tail are now situated in the fuselage.
NEW:
The wing is now pushed onto the fuselage from the side. For electrical connection a plug is let into the root rib.
NEW:
The wingtips were modified for good-natured flying characteristics.
NEU:
precise and simple mounting of the levers by prefabricated recess
NEU:
The servo boxes were optimized for all standard servos, specifically: Futaba S3150, with mounting frame

Stiff shell of the wing 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.
