This is the 55mm Folding Propeller Hub for a 45mm Spinner from
                        Advanced Precision Composites.
        For use on Electric powered aircraft only (not for gas engines).

FEATURES: Two-piece, gray composite propeller hub that goes on each side of
            the folding propeller blades to hold them in place (blades are not
            included, see REQUIRES)
          Hub has molded nut insets for easy tightening
          Comes in a bag attached to a header card

INCLUDES: One composite propeller hub
          Two 3x10mm cap head screws
          Two 3mm nuts
          Two 3mm washers

REQUIRES: Propeller blade sets (use APCQ4305 through APCQ4360)
          2.5mm hex wrench (GPMR8012) to tighten cap head screws
          Hand and eye protection when operating propeller

SPECS:    Overall Length: 63mm
          Length between blade mounting centers: 50mm
          Inner mounting diameter: 8mm

COMMENTS: See propeller blades for assembly instructions.
          Sailplanes have no landing gear, and therefore would break a rigid
            propeller when the plane came in for a landing. The folding
            propeller folds back upon landing.
          The use of this hub will shorten the overall diameter of the prop
          by 10mm from the manufacturer's length listing.
