...The shell is attached to a chassis from German AL-KO Cobra with V-type tow bar and an over run brake.
Wings and fuselage are loaded through opening in the back of the trailer and guided by set of built-in rails.
At the front of the trailer there is a baggage compartment for stowing all ground handling equipment and a spare wheel.
Unconventional arrangement of "Diana 2" structural design with 1.5 meter spar stump integrated into fuselage, suggested development of a new trailer that would be adequate for storage and transport of both "Diana 2" as well as any other modern high-performance sailplane.
Trailer has a unique monocoque composite shell. The 15mm thick floor is made from sandwiched aluminum plate with honeycomb core...
Standard trailer configuration includes
chassis made from aluminium
axle with brakes (AL-KO or KNOTT)
automatic back-up release with hitch (AL-KO or KNOTT)
