Found a price list from Wicks Aircraft, dated July 1988. The Basic Raw Materials (epoxy, urethane foam, divinycell foam, polystyrene foam, fiberglass, filler material, wood kit, metal kit, bolt kit, screw kit, nut kit, cotter key kit, nutplate kit, washer kit, rivet kit, cable & cable hardware, plumbing, miscellaneous kit) was about $3500 plus shipping.
But there is a lot more needed that is not include in that price such as, wheels/brakes, nose gear, landing gears, nose retract mechanism, cowlings, canopy, motor mount, motor, instruments, prop, electrical, lights, etc.
