10. Pilots Please Attention!
For the first flights we recommend setting
the center of gravity to around 5 mm
forward of the CG tag - nose heavy, this
increases the stability (you can use heavier
battery). Increasing expo settings on your
transmitter for elevator and ailerons to 80
% calms response from your stick inputs.
Also you can decrease elevator, rudder and
ailerons deflection to calm down the
plane.
Make sure the battery is well fixed in proper
possition. If it moves during flight it will
cause shifting of CoG aft and will result in
uncontrolable flight behavior.
After gaining some confidence you can
balance the plane to the Center of Gravity
marks and set Expos to 60 % as shown in
the video/instructions... this gains back
extra maneuverability.
Never fly aft positioned Center of gravity.

Enjoy the fun together!
Piper J-3 Cub is the next of new LW Planes
series designed for easy and cheap flying.
The build is simple even for a beginner. It's
very low weight, easy assembly and
fantastic flight characteristics makes this
model an ideal plane for beginner RC pilots.
Very suitable for dads and kids. Children
will learn some modern building skills and
technology and most of all have fun. This is
the reason, why every dad should have a 3D
printer at home.
This model has been completely designed
with the new PolyLight LW-PLA
mind.
Parts printed from this LW-PLA are light,
easily sanded and glued together. This
model requires only about 300g of this
material, that means it's a very cheap build.
In case of accident, parts can be easily
reprinted with just a filament cost.
We've been testing this material for a years
before this plane was released... The
material is
technology to achieve lightweight, low
density PLA parts. At around 230°C this
material will start foaming, increasing its
volume by nearly 3 times.
Almost all parts of this plane should be
printed from LW-PLA (some specific parts
needs PLA or PETg).
