Erwin XL Medium

Details:

WING:

Since June 2018 our Erwin XL is delivered with a new design.

Upper side with paint and graphic in visible carbon,
underside in visible carbon with white bars (photo of Erwin XL slope).

The shell of the wing is produced as a sandwich construction. As outer skin we use 80g IM Spread-Tow carbon fibre. Upper sides are painted, undersides left in visible carbon.

The wingtips were optimized for good-natured flying characteristics despite high wingload.

Precise and simple mounting of the levers by prefabricated recess,
aerodynamically 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

All rudders are mounted with kevlar.

Rudder gap is closed on wing and V-tail.

Carbon covers for servos are enclosed in the kit.

FUSELAGE:

The fuselage is a carbon-/glass-construction using IM-Spread-Tow carbon.

The radio is placed on the servo tray inside the fuselage cone.

The fuselage cone is manufactured in kevlar or glass to ensure good receipt of 2,4GHz.
The servos for controlling the V-tail are situated in the fuselage ...

... and hinged with bowden cables.

Hook for winch start:
Erwin XL medium can also be used for flying in the plain with all usual starting methods.

The wing is pushed onto the fuselage from the side. For electrical connection a plug is let into the root rib.

The model is also available as electric version.

Engine, controller and battery are placed in the fuselage cone then.

The receiver is located between the wings behind the connector.

V-TAIL:

The V-tail ist also built with sandwich-shell. The outer skin is made of 39g carbon fibre. Upper side is painted, underside left in visible carbon.

The tail is removable.
The V-tail is manufactured in one part.
Holes and threads for mounting the v-tail on the fuselage are pre-fabricated.

In the electric version the servos for elevator and rudder can be installed in the V-tail. By this means you can save weight, as you need no or only little lead when adjusting the centre of gravity.

Protection bags made of stitched foam material coated with aluminium foil
with fabric edging, practical velcro fasteners and strengthenings at the wing tips
