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 to the Original Plane design.
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. This model is larger than
the GP 40 sized cub. 40 cub kit accessories will not fit (ie super
cub conversion) NOTE: The instruction manual incorrectly lists the
wing kit stock number as GPMA2180 the CORRECT stock number is
GPMA2092.
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. |
