I think the Berkut uses metal oleo retracts - Carbon can be made to work
and is potentially lighter for the job than aluminum or titanium, but is
rather expensive both from materials and labor. I have been working
with Pine off list so as to reduce the non rotary exchanges. Vance

You are thinking of the Infinity oleo retracts for canards which are mounted to the center spar ends and retracted inwards and up into the strakes. The Berkut uses molded carbon, mounted to the fuselage and retracted outward and up into the strakes.

Having seen the Berkut several times at SZP the struts are almost stright with 
a very steep angle so I don't think they are working as springs. There must be 
something else doing the springing. I think that was Vances point.
