9. Reinforce holes for wood screws with thin CA
where appropriate (servo mounting screws, cowl
mounting screws, etc.).
❏
10. Confi rm that all controls operate in the correct
direction and the throws are set up according to
the manual.
❏
11. Make sure there are silicone retainers on all
the clevises and that all servo arms are secured to
the servos with the screws included with your radio.
❏
12. Secure connections between servo wires and
Y-connectors or servo extensions, and the connection
between your battery pack and the on/off switch with
vinyl tape, heat shrink tubing or special clips suitable
for that purpose.
❏
13. Make sure any servo extension cords you may
have used do not interfere with other systems (servo
arms, pushrods, etc.).
❏
14. Make sure the fuel lines are connected and
are not kinked.
❏
15. Balance your propeller (and spare propellers).
❏
16. Tighten the propeller nut and cone.
❏
17. Place your name, address, AMA number and
telephone number on or inside your model.
❏
18. Cycle your receiver battery pack (if necessary)
and make sure it is fully charged.
❏
19. If you wish to photograph your model, do so
before your fi rst fl ight.
❏
20. Range check your radio when you get to the
fl ying fi eld.
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 crystal
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. Do not use your fi ngers to fl ip the propeller.
Make all engine adjustments from behind the rotating
propeller.
The engine 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.

Read and abide by the following excerpts from the
Academy of Model Aeronautics Safety Code. For the
complete Safety Code refer to Model Aviation magazine,

license.
