INTRODUCTION
Thank you for purchasing the Tower Hobbies Cherokee EP.
This Cherokee is intended for electric power only, so the
structure has been lightened accordingly to make it a nice
little scale yer. Tricycle landing gear is the icing on the cake
for easy ground handling, takeoffs, and landings.
NOTE: This instruction manual illustrates all the steps
necessary to assemble the ARF (almost ready-to- y) edition
of the Cherokee EP. However, the Rx-R (receiver-ready)
edition requires less assembly, so if assembling the Rx-R,
simply skim through the manual and perform only steps
that apply.

LiPo Battery Charger
To charge a 3S 3200mAh LiPo at 1C a charger capable of
at least 40 watts is required (3S x 4.2V/cell = 12.6V x 3.2A =
40 watts). The Triton EQ (GPMM3155) is more than enough
charger with 50W output using AC and 63W output using DC.
Adhesives, Hardware & Other Accessories

ELECTRIC MOTOR
SAFETY PRECAUTIONS
WARNING! A spinning propeller has the potential to cause
serious and permanent injury.
WARNING! Once the motor batteries are connected, the
propeller can start spinning at any time. Make sure the Fail
Safe is set on your radio to prevent the motor from starting
if the signal is lost.
WARNING! Stand clear of the propeller when handling
the aircraft. Make sure the aircraft is held securely until the
battery has been disconnected.
ALWAYS remove the propeller if the motor batteries will be
connected while working on your plane.
ALWAYS remove the motor batteries from the plane
when charging.
ALWAYS switch on the transmitter rst, then the receiver.
ALWAYS unplug the motor batteries rst before switching
off the receiver then transmitter.
NEVER touch the motor during or right after operation. The
motor gets HOT!
NEVER switch off the transmitter with the motor batteries
plugged in.
NEVER reach through the arc of the propeller when plugging
the battery into the ESC.
LITHIUM BATTERY WARNING!
This product recommends the use of a lithium polymer
(LiPo) battery. Improper handling of a LiPo battery
could result in FIRE! A lithium battery re has the
potential to ignite surrounding areas and may cause property
damage or cause personal injury.
For safe LiPo handling, follow ALL of these guidelines:
MOST IMPORTANT! Never leave the battery or charger
unattended during charging or discharging.
WARNING: Read the entire instruction sheet included with
your batteries. Failure to follow the instructions could cause
permanent damage to the battery and its surroundings and
cause bodily harm!
ALWAYS follow the charging instructions included with your
charger for charging LiPo batteries. LiPo batteries can cause
serious damage or re if misused.
ALWAYS use a LiPo-approved charger.
ALWAYS set the charger’s output volts to match the
battery volts.
ALWAYS charge a LiPo battery in a reproof location.
ALWAYS balance charge the battery pack.
ALWAYS store and transport LiPo batteries in a reproof
container away from combustible materials.
ALWAYS KEEP OUT OF THE REACH OF CHILDREN.
ALWAYS keep LiPo batteries out of the reach of animals. A
punctured battery may cause a re.
ALWAYS disconnect the battery and unplug the charger
after the charge is complete.
ALWAYS keep a supply of sand accessible when charging
a LiPo battery. Dumping sand on the battery will assist in
extinguishing a LiPo chemical re.
ALWAYS remove the batteries from the plane after a crash.
Set them aside in a safe location for at least 20 minutes. If
the batteries are damaged in the crash, they could catch
re. If the battery starts to swell, quickly move the battery to
a safe location, preferably outside away from combustible
material. Place it in a bucket, covering the battery with sand.
NEVER use water to try and put out a LiPo re.
NEVER charge or use a battery that is deformed, bent,
crushed or has any type of visible damage.
NEVER use a NiCd/NiMH peak charger to charge a
LiPo battery.
NEVER charge in excess of 4.20V per cell unless the battery
is rated for a higher voltage.
NEVER charge at currents greater than 1C unless the batter y
is rated for a higher charge rate.
NEVER trickle-charge a LiPo battery.
NEVER allow the battery temperature to exceed 140 degrees
F (60 degrees C).
NEVER disassemble or modify the battery pack wiring in
any way or puncture the cells, as this may result in a re.
NEVER discharge below 2.7V per cell. It is recommended
to not discharge below 3.7V per cell.
NEVER charge the battery or set the charger on combustible
materials.
NEVER charge the battery inside a vehicle or in a location
that could be damaged in the event of a LiPo re.
NEVER put a LiPo battery in the pocket of any clothing.
NEVER charge the batteries in the plane. Disconnect the
batteries and remove them from the plane immediately
after landing.
NEVER allow the battery to short circuit by touching exposed
wires together. This may cause a re.
NEVER operate or store batteries below 40˚F or above
110 ˚ F (4- 43 ˚C)

1. The canopy hatch is removed by pushing the hatch
❏
forward to disengage the magnets and tabs, then lifting the
back of the hatch upward and pulling the canopy back and out.
2. Use a covering iron with a protective cover sock to
❏
remove any wrinkles or areas of loose covering that may have
developed after the covering was originally applied. Start
with low or medium heat to nd the setting that works best
(approximately 300º F measured on the surface of the cover
sock). Gradually increase the heat as necessary to get the
covering to tighten. Too much heat may cause seams and
edges to pull away or damage the color graphics printed onto
the covering. As you proceed, push down on the iron over
sheeted areas to bond the covering to the wood underneath.

3. Test the security of all the control surfaces and the
❏
hinges by pulling to make sure they remain secure. Add a
few drops of thin CA to any hinges that aren’t secure.
4. Stack two or three paper
❏
towel squares on top of each
other and cut them into small
squares. During various
stages of assembly these
squares may be dampened
with denatured alcohol for
epoxy and other kinds of
cleanup.
3. Tape the ends of the servo strings that are inside the
❏
wings to the outside of the wings. Test- t the wing halves
together with the wing joiner and the alignment pin. Make
any adjustments necessary for a good t.
NOTE: Even though you may be using 30-minute epoxy,
some brands of epoxy harden faster than others and time
seems to y when working time is limited, so make sure you
have everything you need to glue the wing halves together
and work ef ciently so you don’t run out of working time
before the epoxy begins to harden.
4. Mix approximately 1/4 oz. of 30-minute epoxy. Working
❏
quickly, pour some epoxy into the spar cavities in both wings
and distribute with a wire or small dowel.
ASSEMBLE THE WING
Join the Wing Halves
1. Use medium CA or epoxy to glue together the two
❏
pieces of the plywood wing joiner.
2. Glue the nylon alignment pin (visible in the following
❏
image) halfway into one of the wing halves.
5. Coat one end of the joiner and insert it into one of the
❏
wing halves. Coat the protruding sides of the joiner and both
root ribs of each wing half. Then, join them together and wipe
away excess epoxy as it squeezes out.
6. Clamp the front of the wing together at the tab and apply
❏
strips of masking tape to tightly pull the wings together. Use
the paper towel squares dampened with denatured alcohol
