airplane designed by Wala Tadeas. Development of the Aerospool WT-9
Dynamic started in 1998. The prototype of the WT9 Dynamic, the D-MXWT
flew first in 2000. For the construction of this aeroplane has been made
optimal use of advanced materials as polyurethane and carbon composites.
The fuselage of the plane consists of composites sandwich shells where
the main construction element is carbon fibre. The ergonomic designed
canopy frame is made out of carbon composite, for the canopy an acrylic
glass design made by Mecaplex is used. As power plant the 80hp Rotax 912
