3P47 Thunderbolt Instruction Manual
history of the p-47
The P-47 was the heaviest US single-engine fighter of WWII and was built in greater quantities than any other. More
than half a million combat sorties were flown in P-47’s between the years of 1943 and the end of the war in 1945. One of
the first true multi-role fighters, the Jug was a fighter, bomber, dive-bomber and ground attack aircraft. The P-47 was
also the first piston-powered fighter to exceed 500 mph.

lithium polymer battery safety
BefoRe chaRging Li-po’S
Before charging your battery check for any damage e.g. check if the battery has expanded or swollen in size or
if the battery cells have been punctured. If any of the above is true: DO NOT CHARGE THE BATTERY!
chaRging Li-po’S
Only use a charger designed to charge Lithium polymer batteries. Never use a nicad or other charger as this is
very dangerous.
Never attempt to charge at a rate faster than that recommended in the instructions. Check that the battery cell
count matches the charger cell count switch (if fitted).
Never charge unattended. Always stay with your battery whilst charging in case of overheating or fire.
Charge on a safe surface or container (e.g. old unused microwave oven). Charge only on non-flammable
surfaces, e.g. concrete floor preferably outdoors, or in a pyrex cooking dish with the battery placed on a bed of
sand, or in a fireplace. Never charge inside a car!
Switch off charger if battery gets too hot. If the battery becomes hot to the touch during charging, disconnect
and switch off immediately.
Extinguish fires with sand. If something goes wrong and your battery catches fire, always have sand from a fire
bucket at hand to douse the flames. Do NOT use water!
uSing Li-po’S
Do not modify/change any part of the battery or lead. Do not remove its heat shrink protective covering.
Removal or modification may damage the battery and will invalidate any warranty claim.
Do not place this battery near fires or anything with high temperatures.
Do not charge batteries while you are driving and do not store batteries in any type of motor vehicle.
Do not let the battery get wet or become submerged in any type of liquid.
Do not carry loose batteries in your pocket or bag as they could short-circuit against other items.
If you should get electrolyte from the cells on your skin, wash thoroughly with soap and water. If in your eyes,
rinse thoroughly with water. Seek medical assistance.
lithium polymer flight battery
Charging lead only
The LiPo flight battery is a high power battery designed to give a flight time of approximately 10mins per charge. It is
supplied in a partially charged state.
As well as a red deans style conector lead (for connection to the ESC) the battery is also fitted with a white 3-pin
polarised connector. This is the charge lead. Connect this white plug to the 12V charger. Always leave the battery in a
partially charged state. Never leave it in a discharged state.
The battery should be charged if you notice the model losing power. At this point land and recharge the battery.
Do not be tempted to run the battery past this stage as you will be over-discharging and the battery may be damaged.
WARNING!
We recommend that you use only the supplied EScale charger with this battery.
WARNING!
Over-discharging will shorten the life of the battery or destroy it. Stop flying immediately you notice the model is
losing power and recharge the battery.
WARNING!
Do not short circuit—battery may explode!
IF YOU HAVE NOT DONE SO ALREADY PLEASE READ THE LITHIUM POLYMER BATTERY SAFETY INSTRUCTIONS
ABOVE BEFORE PROCEEDING ANY FURTHER.

12V Charger
(Only included in RTF
complete set)
LiPo Battery
The charger is designed to automatically charge the LiPo battery in about an hour from a discharged state. The 12V
DC automatic charger is powered by the mains power supply illustrated above. Alternatively, you can use a 12V
sealed modelling battery to power the DC automatic charger.
1. Connect the charger to the power source.
The power LED will light Red and the charge
LED will light Green.
2. Plug the white 3-pin connector on your Li-po
battery into the 3pin socket in the front of the
charger.
Charging: Charge LED flashes Red.
Fully charged: Charge LED is solid Green.
If the charge LED is solid Red when you plug in the
battery no charge is needed.
3. When the battery is fully charged disconnect the
battery from the charger. Disconnect the 12V
power source from the charger. Your Li-po is
ready for use.
6 P47 Thunderbolt Instruction Manual
assembling the p-47
1. Locate the horizontal tail assembly and the
vertical fin and rudder assembly.
Note: Picture shows the horizontal tail with double-
stick tape for attching to the vertical fin. We
recommend that you remove the double sided tape
and use epoxy to glue the vertical and horizontal
fin together as this will provide a more permanent
fixing.
2. Use the vertical fin to locate the position
of the alignment holes in the horizontal tail.
Using a sharp hobby knife carefully cut away
the double-stick tape in these 2 positions. Dry
fit the vertical fin to confirm a good fit.
3. Peel the backing paper from the double-
stick tape, or use epoxy glue, and press the
vertical fin into position. You will now have a
single unit of horizontal and vertical tail parts
ready to glue to the fuselage.
4. Locate the main fuselage.
7P47 Thunderbolt Instruction Manual
5. In the center of the rear of the fuselage, cut
a vertical slot to accept the hinge that is pre-
attached to the bottom of the rudder. A sharp
hobby knife is best for this operation.
6. Trial fit the tail unit to the fuselage.
7. Epoxy the tail unit to the fuselage.
EPOXY
8. When the epoxy has set, connect the plastic
clevis to the rudder control horn.
9. Connect clevis to the outermost hole in the
control horn.
8 P47 Thunderbolt Instruction Manual
10. In like manner, connect the plastic clevis to
the control horn on the elevator.
11. With the fuselage upside down, place
the leading edge of the main wing on the
fuselage.
12. Locate the single servo extension on the
receiver and plug the retract servo into it.
13. Plug the remaining “Y” connector into the 2
aileron servo extensions. It does not matter
which servo is plugged into which side of the
“Y” connector.
14. Place the wing into the fuselage wing saddle.
Route the main power wires from the ESC to
the bottom side of the wing. You may need
to make a groove in the leading edge of the
wing for these wires. (See Photo)
15. Locate the 2 long metal screws and screw
them in place.
9P47 Thunderbolt Instruction Manual
16. The flight battery slides in place in the hollow
compartment bellow and to the front of the
main wing. Velcro on the bottom of the wing
and on the battery help keep it in place.
17. The lower fuselage under wing filler is held in
position at the front by a tab and at the rear
by strong magnets. No tools are required to
remove for access to the flight batteries.
18. Install the gun units onto the the main wing.
Take care to mount them on the correct side.
Each gun unit is marked L and R to aid with
this.
10 P47 Thunderbolt Instruction Manual
assembling the propeller
19. Locate the scale propeller parts.
20. Begin by inserting the blades onto the front
prop hub.
21. When all four blades are in position your
propeller should look like the photo at the
right.
22. Snap the rear prop hub in place and insert the
four screws and tighten.
23. Slip the prop onto the motor shaft and install
the washer and nut.
