Fernando:
What plans are you looking for? Bensen wood blades?
The PRA.ORG web site has a download section for the B7/B8 and look for the file described as
"Bensen Laminated upper Rotor-blade Skin" for the plywood/pine versions. You have to register as a member of PRA though.
And on another site there are plans for the B19/20 that have douglas fir plank blades.

They are in PDF format and easily downloaded.
