GPMA1311   Piper J-3 Cub Fabric Covered .40 ARF

TECH NOTES
     This is a Piper J-3 Cub .40 1/4 Scale R/C Glow Powered ARF Airplane
             Pre-Covered in Genuine Coverite 21st Century Fabric.
90% Factory-Built and Truer to the Original Plane than Most other R/C versions.
          This kit is designed for the Beginner to Intermediate Flier.

FEATURES: Huge IMAA - Legal 81" Wingspan.
          Excellent first sport-scale kit - assembles quickly, maneuvers well
            and lands slow and easy.
          One-piece 81" bolt-on wing
          Reproduces the full-scale aircraft with amazing accuracy, using
            precise CAD engineering and data from original Piper 3-view
            drawings.
          Can be flight-ready in 15-20 hours.  The prebuilt, all-wood major
            sections come precovered with Coverite Fabric - real woven cloth,
            featuring a simulated, hand-rubbed lacquer finish.  Lightweight, it
            resists scratches, tears and punctures better than most films.
          Roomy radio compartment simplifies installation of on-board
            components and provides space to install a fully detailed cockpit
            and pilot (both optional).
          Uses authentic "barn door" ailerons to maximize realism.  Dual
            aileron servos add precision and authority to control response for
            crisp maneuvers.  The linkage simplicity makes aileron set-up a
            snap.
          One-piece fiberglass cowl comes factory-painted to match the fabric
            covering and a precision-formed, ready-to-paint replica cylinder
            head is also included.
          Includes an adjustable engine mount; premium-quality, Great Planes
            brand hardware; and decals for authentic markings and N-numbers.
          Wood wing struts come pre-sanded into an airfoil shape.  They provide
            a more authentic look than flat struts, and improve the model's
            flight performance by keeping drag to the absolute minimum.
          90-Day Warranty.

COMMENTS: The pilot figure shown in the picture is not included, use 1/5 scale.
  Floats: This model does not have float mounts in it.  The model would need to
            be modified to accept floats.  The GPMQ1874 60-size Float Kit will
            work with this kit.

           If a replacement fuel tank is needed the Great Planes 8oz,
             GPMQ4103 can be used. A separate section of plywood must be glued
             to the firewall to clear the lip on the replacement tank and the
             stopper hole redrilled in the firewall.

          This model is larger than the GP 40 sized cub.
            40 cub kit accessories will not fit (ie super cub conversion)

 TECH NOTE: About joining wings- pg.6 of instructions says to test fit the wing
            halves and to sand any high spots on the root end of the wings so
            there is no gap when you join them.  If there is too large a gap to
            sand away, it may be shimmed with a piece of balsa and balsa filler
            or epoxy.  The idea is that the wing is  straight upon assembly,
            and has no twisting motion at the joint. Epoxy gives more weight
            than balsa filler, or micro balloon filler which can also be used
            to fill the gap. This wing is flat-bottom and can be assembled on a
            flat surface.
