The fi nal variant of the P-47 was the P-47N-25
rolling off the Republic Farmingdale production line
in 1945. The “N” featured squared-off clipped wing
tips and an increased wingspan to accommodate
four additional 50-gallon internal wing tanks. The
goal of increasing range to fulfi ll the roll of bomber
escort (and to become more competitive with the
P-51 Mustang) was accomplished.
PREFLIGHT
IDENTIFY YOUR MODEL
No matter if you fl y at an AMA sanctioned R/C club site
or if you fl y somewhere on your own, you should always
have your name, address, telephone number and AMA
number on or inside your model. It is
required
at all AMA
R/C club fl ying sites and AMA sanctioned fl ying events.
Fill out the identifi cation tag on page 36 and place it on
or inside your model.
CHARGE THE BATTERIES
Follow the battery charging instructions that came with
your radio control system to charge the batteries. You
should always charge your transmitter and receiver
batteries the night before you go fl ying, and at other times
as recommended by the radio manufacturer.
CAUTION:
Unless the instructions that came with your
radio system state differently, the
initial
charge on
new
transmitter and receiver batteries should be done for
15 hours
using the slow-charger that came with the
radio system
. This will “condition” the batteries so that
the next charge may be done using the fast-charger
of your choice. If the initial charge is done with a fast-
charger the batteries may not reach their full capacity
and you may be fl ying with batteries that are only
partially charged.
GROUND CHECK AND RANGE CHECK
Run the engine for a few minutes to make sure it idles
reliably, transitions smoothly and maintains full power
indefi nitely. Afterward, shut the engine off and inspect
the model closely, making sure all fasteners, pushrods
and connections have remained tight and the hinges are
secure. Always ground check the operational range of
your radio before the fi rst fl ight of the day following the
manufacturer’s instructions that came with your radio.
This should be done once with the engine off and once
with the engine running at various speeds. If the control
surfaces do not respond correctly,
do not fl y!
Find and
correct the problem fi rst. Look for loose servo connections
or broken wires, corroded wires on old servo connectors,
poor solder joints in your battery pack or a defective cell,
or a damaged receiver from a previous crash.
ENGINE SAFETY PRECAUTIONS
Failure to follow these safety precautions may
result in severe injury to yourself and others.
Keep all engine fuel in a safe place, away from high
heat, sparks or fl ames, as fuel is very fl ammable. Do
not smoke near the engine or fuel; and remember that
engine exhaust gives off a great deal of deadly carbon
monoxide. Therefore
do not run the engine in a closed
room or garage
.
Get help from an experienced pilot when learning to
operate engines.
Use safety glasses when starting or running engines.
Do not run the engine in an area of loose gravel or sand;
the propeller may throw such material in your face or eyes.
Keep your face and body as well as all spectators away
from the plane of rotation of the propeller as you start
and run the engine.
Keep these items away from the prop: loose clothing, shirt
sleeves, ties, scarfs, long hair or loose objects such as
pencils or screwdrivers that may fall out of shirt or jacket
pockets into the prop.
Use a “chicken stick” or electric starter to start the engine.
If you do fl ip the prop with your hand, protect it with a
thick glove such as a welder's glove.
Make all engine adjustments from behind the rotating
propeller.
The engine or motor gets hot! Do not touch it during or right
after operation. Make sure fuel lines are in good condition
so fuel will not leak onto a hot engine, causing a fi re.
To stop a gasoline powered engine an on/off switch
should be connected to the engine ignition. Do not throw
anything into the propeller of a running engine.
MOTOR SAFETY PRECAUTIONS
ALWAYS
remove the propeller if the motor batteries
will be connected while working on the plane.
ALWAYS
follow the charging instructions included with
your charger for charging LiPo batteries. LiPo batteries
can cause serious damage if misused.
WARNING:
Once the motor batteries are connected
the electric motor can start at any time. Make sure the
fail safe is set on your radio to prevent the motor from
starting if the signal is lost.
ALWAYS
unplug the motor batteries fi rst.
NEVER
switch off the transmitter with the motor
batteries plugged in.
WARNING:
Read the entire instruction sheet included
with your motor batteries. Failure to follow the
instructions could cause permanent damage to the
battery and its surroundings and cause bodily harm!
ONLY
use a LiPo approved charger.
NEVER
use a NiCd/NiMH peak charger to charge a
LiPo battery.
NEVER
charge in excess of 4.20V per cell.
ONLY
charge through the “charge” lead.
NEVER
charge through the “discharge” lead.
NEVER
charge at currents greater than 1C unless the
battery is rated for a higher charge rate.
ALWAYS
set the charger’s output volts to match the
battery volts.
ALWAYS
charge a LiPo battery in a fi reproof location.
NEVER
trickle charge a LiPo battery.
NEVER
allow the battery temperature to exceed 150
degrees F (65 degrees C).
