Introduction
The Republic P-47 Thunderbolt was a World War II era fighter aircraft that served with the United States Army Air Forces.
Weighing in at eight tonnes when fully loaded, it was one of the heaviest fighters and ground attack aircraft of its era.
Carrying M8 rocket pods and a 2500lb payload of bombs, it was highly effective in ground attack missions.
Arrow Works is proud to introduce the intricately detailed 980mm P-47. Featuring retractable landing gear, a realistic four
bladed propeller, removable auxiliary fuel tank, bombs and rocket pods- the P-47 faithfully replicates its full-sized World
War II counterpart.
Features:
• Power system- 3536 850KV Motor, 40A ESC.
• Highly detailed: realistic and functional flaps and landing gear.
Removable auxiliary fuel tank, bombs and rocket pods. Panel
lines, LED lights and a painted pilot figure.
• Simple connector minimizes the need to connect multiple
servo leads.
• Oversized battery compartment for a multitude
of battery sizes and capacities.
• Preinstalled ball-linked servo horns, increased
control precision.

Preflight check
Important ESC and model information
1. The ESC included with the model has a safe start. If the motor battery is connected to the ESC and the throttle stick is not in the low
throttle or off position, the motor will not start until the throttle stick is moved to the low throttle or off position. Once the throttle stick is
moved to the low throttle or off position, the motor will emit a series of beeps. Several beeps with the same tune means the ESC has
detected the cells of the battery. The count of the beeps equals the cells of the battery. The motor is now armed and will start when the
throttle is moved.
2.
The motor and ESC come pre-connected and the motor rotation should be correct. If for any reason the motor is rotating in the wrong
direction, simply reverse two of the three motor wires to change the direction of rotation.
3. The motor has an optional brake setting. The ESC comes with brake switched off and we recommend that the model be flown with
the brake off. However, the brake could be accidentally switched on if the motor battery is connected to the ESC while the throttle stick
is set at full throttle. To switch the brake off, move the throttle stick to full throttle and plug in the motor battery. The motor will beep one
time. Move the throttle stick to low throttle or the off position. The motor is ready to run and the brake will be switched off.
4. Battery Selection and Installation. We recommend the 11.1V 2200mAh 25C Li-Po battery. If using another battery, the battery must
be at least a 11.1V 2200mAh 25C battery. Your battery should be approximately the same capacity, dimension and weight as the 11.1V
2200mAh 25C Li-Po battery to fit the fuselage without changing the center of gravity significantly.

Preflight check
transmitter and model setup
After assembly and prior to your first flight, make sure all control surfaces respond correctly to your transmitter by referring
to the diagram below.
Control throws
The suggested control throw setting for the P-47 are as follows (dual rate setting):
Tip: The maiden flight should always be
flown using low rates, fly the aircraft until you
are familiar with its characteristics prior to
trying high rates. Make sure the aircraft is
flying at a decent altitude and speed prior to
using high rates, as the aircraft will be sensitive to control inputs with the larger control
surface movements.

Finding the center of gravity
Finding the correct center of gravity is critical in ensuring that the
aircraft performs is a stable and responsive manner. Please
adjust the weight distribution so the aircraft balances in the range
stated on the diagram.
• Depending on the capacity and weight of your choosen flight
batteries, move the battery forward or backward to adjust the
center of gravity.
Arms
More control throw
Less control throw
50mm-55mm
• If you cannot obtain the recommended CG by moving the battery to a
suitable location, you can also install a counterweight to achieve correct
CG. However, with the recommended battery size, a counterweight is not
required. We recommend flying without unnecessary counterweight.
Before flying the model
Find a suitable flying site
Find a flying site clear of buildings, trees, power lines and other obstructions. Until you know how much area will be required
and have mastered flying your plane in confined spaces, choose a site which is at least the size of two to three football fields
- a flying field specifically for R/C planes is best. Never fly near people - especially children, who can wander unpredictably.
Performing a range check
A radio range check should be performed prior to the first flight of the day. This test may assist you in detecting electronic
problems that may lead to a loss of control- problems such as low transmitter batteries, defective or damaged radio components or radio interference. This usually requires an assistant and should be done at the flying site.
08
Page 10
Before flying the model
Always turn your transmitter on first. Install a fully charged battery in the battery bay, then connect it to the ESC. In this
process, make sure that the throttle cut functionality is on, and that the throttle stick is secured in its lowest position- otherwise, the propeller/fan will engage and possibly cause bodily harm.
Note: Please refer to your transmitter manual that came with your radio control system to perform a ground
range check. If the controls are not working correctly or if anything seems wrong, do not fly the model until you
correct the problem. Make certain all the servo wires are securely connected to the receiver and the transmitter
batteries have a good connection.
Monitor your flight time
Monitor and limit your flight time using a timer (such as a stopwatch or on the transmitter, if available). As modern Lithium
Polymer batteries are not designed to discharge completely, when the battery runs low, the ESC will lower then completely
cut the power to the motors to protect the battery.Often (but not always) power can be briefly restored after the motor cuts
off by holding the throttle stick all the way down for a few seconds.To avoid an unexpected dead-stick landing on your first
flight,set your timer to a conservative 4 minutes. When your alarm sounds you should land right away.
Flying course
Take off
Point the aircraft into the wind while slowly applying power until the aircraft starts to track straight, use the rudder when
necessary. When the aircraft reaches takeoff speed, ease back on the elevator stick until the aircraft is climbing at a
constant rate without decelerating. Climbing at too steep of an angle at the relatively low speeds of a takeoff-climb may
result in an aerodynamic stall.
Flying
Always choose a wide-open space for flying your plane. It is ideal for you to fly at a sanctioned flying field. If you are
not flying at an approved site always avoid flying near houses, trees, wires and buildings. You should also be careful to
avoid flying in areas where there are many people, such as busy parks, schoolyards, or soccer fields. Consult laws and
ordinances before choosing a location to fly your aircraft. After takeoff, gain some altitude. Climb to a safe height before
trying technical manoeuvres.
Landing
Land the aircraft when you start to feel sluggish motor response. If using a transmitter with a timer, set the timer so you
have enough flight time to make several landing approaches.The model’s three point landing gear allows the model to land
on hard surfaces. Align model directly into the wind and fly down to the ground. Fly the airplane down to the ground using
1/4-1/3 throttle to keep enough energy for proper flare. Before the model Zouches down, always fully decrease the throttle
to avoid damaging the propeller or other components. The key to a great landing is to manage the power and elevator all
the way to the ground and set down lightly on the main landing gear. After a few flights you will find the model can be set
down lightlyon the mains and you can hold the nose wheel off balancing themodel on the mains until it slows and gently
settles the nose.
Maintenance
Repairs to the foam should be made with foam safe adhesives such as hot glue, foam safe CA, and 5min epoxy.
When parts are not repairable, see the spare parts list for ordering by item number.
Always check to make sure all screws on the aircraft are tightened. Pay special attention to make sure the spinner is
firmly in place before every flight.
