say thanks to bruce tharpe to provide us wich such wonderfull hig quality builder's kit allowing our imagination to work !

A part of the credit also goes to a guy called Neil, who instaled a mechanical retract on a DV in 2001 . My instalation is sligthly diferent ( pneumatic system, no top spars, bottom spruce spars instead of balsa, diferent nose unit setup, less aera sheeted), but the main ideas are coming from the work of this guy

here is the link
