Erwin DS

erwin
Prices:

Standard Carbon: £375
DSS Carbon: £425
Painted top surface add: £35.00

 The Erwin DS   is designed for dynamic soaring, it is built with the stress level of ds  and ease of flying in mind,it has a carbon glass carbon sandwich, tape on wings so in case of hard landings they can eject and an efficient airfoil.

Technical Data

   
Wingspan. [mm]:
- 2 000
Weight [g]:
- 1 250 (DS 1 450)
Airfoil
- HQW/1,5/7 mod.
Aspect ratio:
- 13,54
Fuselage:
- CFR/GFR, with CFR rovings
Wing:
- cutted wing (in the middle) --> little package easy to handle in the car or an backpack.
- CFR/GFR shell construction without support material. That's why the surface is more resistant against damage.
- spar with CFR/GFR-hose
- Elliptical lift distribution
- crescent-shaped wing-tip
- HQW/1,5/7 mod. - very good for use with plain flaps
V-tail:
- CFR shell construction without support material
- spar with CFR/GFR-hose

Prefabrication:

 

  

Closed fuselage for more stability
Two wing-connectors possible
Ballast possibility
Covered flaps

Servo-cover
Detail elevator
Sideview V-tail
Servoboard

Erwin XL



 
Price:

£600.00

Closed fuselage for high stability. Crash landings can normally result in at least partial damage with any other fuselage construction (nose-cone, canopy). Thanks to appropriate solutions in the fuselage of Erwin XL there are no disadvantages for handling. f.e. switch, load socket on the outside of the fuselage.

Stiff shell wing without CFC-sandwich-construction. Transport and landings in rough terrain won't create permanent dents on the wing as is the case with sandwich-constructions. All that remains are possibly some scratches. Upper side with paint, available in white, yellow and red, underside in visible carbon

The wing is mounted with tape to create a defined breaking point. After some initial scepticism this fixing solution has been fully tested and approved from feedback of our 2m-Erwin-customers. If you have a hard landing, the wing loosens from the fuselage and in most cases there is nearly no damage. Many Erwin-lifes have already been saved by this way of mounting.

For use ifrom flat fields we offer the option to mount the wing with screws.
