The ARDA v2.0 Mk1 is the 1/4 scale of the ARDA v2.0 (the real EHD flying version). This model has been built to test the aerodynamical model of the wing in free flight.
This scaled model of the ARDA v2.0 will allow me to conduct some tests :

- Validation of the aerodynamical model in free flight,

- Adjustements of the center of gravity,

- Wing loading tests,

- EHD setup and installation.

ARDA v2.0 Mk1 specifications (1/4 scale of the v2.0) :
Wing span : 360mm
Lenght : 315mm

^{Aifoil profile : Eppler 338}

Weight: 38g

The ARDA v2.0 Mk1 is now ready for the first free flight tests....
