One of the most popular civilian aircraft of all time, the J-3 Cub
is often seen around airshows and classic events today. Now
indoor and backyard flyers can experience the fun of shooting
touch and goes on a smaller scale with this incredible scale
3-channel reproduction from ParkZone.
This J-3 Cub offers classic Cub looks and performance in an
ultra-micro sized package featuring Spektrum’s 2.4GHz DSM2
™
control. With a flying weight of only 0.85 oz (24.0 g), the J-3 can
be flown at a gym or in your yard without having to make a trip
to the flying field. The J-3 Cub is designed for experienced pilots
that have previously flown 3-channel aircraft. Your J-3 comes
100% factory-assembled and is ready to fly with everything
included (except a transmitter for BNF only). Also included in the
box is the lithium polymer flight battery and convenient DC Li-Po
battery charger, along with 4 AA batteries for the charger.
The DSM2 technology offers freedom from frequency
restrictions and allows the J-3 Cub to be flown just
about anywhere.
Although the J-3 Cub is nearly ready-to-fly right from the box,
please take time to read through this manual for tips on battery
safety and charging, control setup and more before making your
first flight. It is important that you only charge the included 3.7V
120mAh 14C Li-Po battery (PKZ1035) with the included 1S 3.7V
DC Li-Po Battery Charger (PKZ3240). You can also use the
E-flite
®
Celectra
™
4-Port Charger (EFLC1004). This charger safely
charges four 3.7V packs independently. Attempting to charge
the battery using another Li-Po battery charger or non-Li–Po
compatible charger could result in serious damage.
As the user of this product, you are solely responsible for
operating it in a manner that does not endanger yourself
and others or result in damage to the product or the property
of others.
