Introduction and History
The Flying Tigers, known officially as the 1st American Volunteer Group (AVG), were a unit of the
Chinese Air Force, recruited from U.S. aviators. From late 1941, the P-40B was used by the
Flying Tigers. They were divided into three pursuit squadrons, the "Adam & Eves", the "Panda
Bears" and the "Hell's Angels”.[48]
Compared to opposing Japanese fighters, the P-40B's strengths were that it was sturdy, well
armed, faster in a dive and possessed an excellent rate of roll. While the P-40s could not match
the maneuverability of the Japanese Army air arm's Nakajima Ki-27s and Ki-43s, nor the much
more famous Zero naval fighter in a slow speed turning dogfight, at higher speeds the P-40s were
more than a match. AVG leader Claire Chennault trained his pilots to use the P-40's particular
performance advantages.[48] The P-40 had a higher dive speed than any Japanese fighter
aircraft of the early war years, for example, and could be used to exploit so-called
"boom-and-zoom" tactics. The AVG was highly successful, and its feats were widely published,
to boost sagging public morale at home, by an active cadre of international journalists. According
to their official records, in just 6 1/2 months, the Flying Tigers destroyed 115 enemy aircraft for
the loss of just four of their own in air-to-air combat.
The FMS 980MM P-40B Flying Tiger is avaibalbe in High Speed versiono which is capable of
extreme speeds up to 100mph.

Additional Required Items
Tools and Adhesives
O Glue Brush
Transmitter/Receiver (required for PNP and kit version)
This model requires a 6 channel receiver and transmitter.
Battery/Charger (required for PNP and kit version)
A 14 .8Y 2200 mAh 25C Li-Po Battery is recommended for the High Speed (HS) version. If using
another battery, it must be the same voltage, approximately the same capacity, dimensions, and
weight to fit in the fuselage without changing the center of gravity significantly. A standard Li-Po
Battery Balancing Charger is required to safely charge the battery. Caution: Using a higher
voltage Li-Po Battery than recommended could exceed the maximum capacity of the ESC and
motor and result in ESC failure during flight. This would cause a complete loss of control creating
a potentially dangerous condition.
The HS kit version requires a brushless 3648-KV770 motor, a 70A ESC with 5A SBEC, (6) 9g
digital metal gear servos, and a 10.5x7 three blade propeller.

Generic Binding Instructions
Binding is the process of programming your receiver to respond to your specific transmitter.
Always follow your radio equipment manufacturer's specific binding instructions. Below is a
typical generic procedure for reference:
1.Power off the transmitter.
2.5et the throttle control on the transmitter to its lowest position (all other controls should be
at their neutral position).
3.Install binding plug in receiver bind port.
4.Connect the battery to the ESC.
a5. The receiver LED will flash rapidly.
6. Turn on the transmitter while holding the bind button or switch in the bind position.
7. When the receiver binds, the LED on the receiver will turn on and remain steady.
8.Remove the binding plug from the receiver.
Note: We recommend re-binding the radio after all the control throw settings are adjusted. This
will keep the servos from moving full stroke while the transmitter and receiver connect.
ESC Information
Please refer to the ESC instruction at the end of Manual for detaler information about your
programmable ESC.
Motor Rotation
The motor and ESC comes pre-connected. The direction of motor rotation should be
counterclockwise (fig. 22). If the motor is rotating in the wrong direction, simply reverse two of
the three motor wires to change the direction of rotation.
Control Surfaces
Center Adjustment (trim)
Follow all safety precautions as outlined in this manual and your transmitter
manufacturer's manual, including setting the throttle to the off position.
Turn on the transmitter and plug in the ESC battery.
Center all the trim controls on the transmitter.
Look at all the control surfaces to determine which ones need adjustment.
Unplug the ESC battery and turn off the transmitter before attempting any adjustments.
Adjust clevises as necessary to center control surfaces to their neutral position.
Repeat steps 1 thru 4 to verify adjustments.
If more adjustment is required, repeat steps 5 and 6 until process is completed.
Please see the following for reference; ailerons (fig. 23), rudder, elevator and, rear landing gear
(fig. 24). Note: the rudder and rear landing gear neutral position is adjusted by loosening one of
the screws on the control connector and moving the linkage rod. Tighten the screw when the
adjustment is complete (fig. 25). The other control surfaces are adjusted by disconnecting the
appropriate end of the control rod linkage and turning the threaded connector on the linkage
Direction Check
Turn on your transmitter and receiver. Viewing the model from the rear, move the controls on
the transmitter per the instructions that follow and verify the control surfaces are responding in
the appropriate direction. You may have to reverse the direction of one or more channels on
your transmitter to correct any issues.
1. Move the left joystick to the right. The rudder should move to the right. Move the
joystick to the left. The rudder should move to the left. Reverse channel on
transmitter if necessary.
2. Move the right joystick down towards the bottom of the transmitter. The elevator
should move up. Move the joystick towards the top of the transmitter. The elevator
should move down.
3. Move the right joystick to the right. The right aileron should go up. The left aileron
should go down. Move the joystick to the left. The right aileron should go down. The
left aileron should go up.
Travel Settings (throw)
Adjust the throw by moving the clevis position on the control surface horns. A commercially
available gauge is helpful in this task though not required. If you have a single rate transmitter,
adjust throws to low rate settings. If you have a dual rate transmitter, adjust the throws to
achieve high rate settings.
Aileron Control Throw Setting (low rate)
10 mm up/down (fig. 26-28). Pictures are for reference only on how to use the gauge.
Elevator Control Throw Setting (low rate)
8 mm up/down
Rudder Control Throw Setting (low rate)
7 mm left/right
Flap Control Throw Setting
10 mm mid down
25 mm full down
Mote: Measure the throw (deflection) at the widest point (chord) of each control surface.
Dual Rates and Exponential Recommendations
On many transmitters, dual rates can be setup for aileron, elevator, and rudder channels. If
your transmitter is capable, designate a switch on the transmitter to change between a low and
high rate of servo travel for each channel. Low rates are for normal flying. High rates are for
extreme aerobatics.
To use dual rates, the control surface throw settings should be set to equal the high rate
settings. When the transmitter switch is in the high rate position, the control surface will travel
100%. When the transmitter switch is in the low rate position, the servo will travel less than
100% (a percentage that you determine) to make the control surface throw equal to the low rate
Aileron high rate14 mm up/down
Elevator high rate15 mm up/down
Rudder high rate12 mm left/right
Final Assembly, Detailing, and Propeller Set
m 1) Locate the machine gun sets "M". Test fit one of the gun sets on the leading edge
side of the wing. Match the color and taper of top side of the wing to the corresponding
color and taper of the gun set (fig. 29).
0 2) Once you have determined where each gun set fits, remove them, apply glueevenly,
and re-install (fig.30).
d 4) Slide the external fuel tank "0" into the slot on the bottom of the fuselage as shown
(fig.31-32). Note: This step is optional as the external fuel tank could reduce performance.
Install the Propeller Assembly
a 5) Prior to installing the propeller assembly, balancing is recommended. There are
commercially available balancers for this task. Please follow the manufacturer's
instructions carefully.
о 6) Key the propeller assembly to the motor shaft by fitting the assembly over the hex nut
on the shaft "J" (fig. 33).
о 7) Install the propeller to the motor shaft and make sure the root of the propeller sits right
on the sadddle with the painted propeller tips facing the frot of the plane. Secure the bullet
into place using a screw driver. (fig.34)
O B)Secure the spinner into place using the included machine screw. (fig. 35-36)
Center of Gravity
Before balancing your model, make sure the it is completely assembled, the battery is installed,
and the retractable landing gear is in the lowered position. The recommended center of gravity
(CG) for your model is 45-50 mm from the wing's leading edge (measured at point of contact with
fuselage). Lightly mark the ideal center of gravity position on the top surface of the wing on each
side of the fuselage. Support the plane inverted at the marks made on the top of the wing with
your fingers or a commercially available balancing stand. It should be level or just slightly nose
down. Adjust the position of battery as necessary to achieve the proper balance.

оо моем
1. Brake: ON/OFF
* ON-Sets the propeller to the brake position when the throttle stick is at the minimum position (Recommended for
folding props).
* OFF-Sets the propeller to freewheel when he throttle stick is atthe minimum position.
2. Battery type: LiPo or NiCad/NiMh
* NiCad/NiMh — Sets Low Voltage protec tion threshold for NiCad/NiMh cells.
* LiPo — Sets Low voltage protection threshold for LiPo ce lls and automatically detects the number of cells within the
Note: Selecting the NiCad/NiMh option for the battery type, triggers the ESC to automatically set the cutoff threshold
to the factory default of 65%. The cutoff threshold can then be subsequently altered through the Low Voltage
protection function, if required. The ESC will read the initial voltage of the NiCad/NiMh pack once it is plugged in and
the voltage read will then be used as a reference for the cutoff voltage threshold.
3. Low Voltage Protection Threshold (Cutoff Threshold):
Low / Medium / High
1) For Li-xx packs- number of cells are automatically calculated and requires no user input apart from defining the
battery type. This ESC provides 3 setting options for the low voltage protection threshold; Low (2.8V)/ Medium
(3.0V)/ High (3.2V). For example: the voltage cutoff optiongor an 11.1V/ 3 cell Li-Po pack would be 8.4V (Low)/ 9.0V
(Med)/ 9.6V (High)
2) For Ni-xx packs-low / medium / high cutoff voltages aré0%/65%/65% of the initial voltage of the battery pack. For
example: A fully charged 6 cell NiMh pack’ s voltage is 1.44Vx 6=8.64V,when "LOW" cutoff voltage is set, the cutoff
voltage is: 8.64V x 50%=4.3V and when “Medium” or "High" is set, the cutoff voltage is now 8.64V X 65%=5.61V.
4. Restore factory setup defaults:
Restore - Sets the ESC back to factory default settings;
Brake : Off
Battery type Detect : LiPo with Automatic Cell
Low voltage cutoff threshold: Medium (3.0V/65%)
Timing setup : Automatic
Soft Acceleration Start Up : Medium
Governor mode : OFF
Frequency : 16kHz
Low voltage cutoff type : Reduce power
5. Timing setup: Automatic / Low / High.
* Automatic — ESC automaticallydetermines the optimum motor timing
* Low (7-22 deg) — Setting for most 2 pole motors.
* High (22-30 deg)-setting for motors with 6 or more poles.
In most cases, automatic timing works well for all typesof motors. However for high efficiency we recommend the
Low timing setting for 2 pole motors (general in-runners)and high timing for 6 poles and above (general outrunners).
For higher speed, High timing can be set. Some motors require different timing setupstherefore we suggest you
follow the manufacturer recommended setup or uséhe automatic timing setti ng if you are unsure.
Note: Run your motor on the ground first after making any changes to your motor timing!
6. Soft Acceleration Start ups: Very Soft / Soft Acceleration/ Start Acceleration
* Very Soft — Provides initial slow1.5 sec ramp-up from start to full rpm intended to protect delicate gears from
stripping under instant load. This setting is recommended for either fixed wing models equipped with gearboxes and /
or helicopters.
* Soft Acceleration- Provides initial slow 1 sec ramp-up from start to full rpm. This setting is recommended for either
fixed wing models equipped with gearboxes and or helicopters.
* Start Acceleration — Provides quick a cceleration start ups with a linear throttle response. This is recommended for
fixed wing models fitted with direct drive setups.
7. Active RPM Control (Heli Governor Mode)
* RPM control off
* First range:There will be a 5-second delay from start to full rpm, but if the throttle is cutoffafter starting,then the
next startwill be as normal start.
* Second range: There will be a 15-second delay from start to full rpm, but if the throttle is cutoffafter starting,then
the next startwill be as normal start.
Note: Once the Governor Mode is enabled, the ESC s Brakeand Low Voltage Cutoff Type settings will automatically
be reset to No Brake and Reduce Power respectively regardless of what settings they were previously set.
8. Motor Rotation: Reverse
In most cases motor rotation is usually reversed byswapping two motor wiresHowever, in cases where the motor
cables have been directly soldered tothe ESC cables, motor rotation can be reversed by changing the value of
setting on the ESC.
9. Switching Frequency: 8 kHz/16kHz
* 8 kHz — Sets ESC switching frequency for 2 pole motors, e.g. in-runners.
* 16 kHz — Sets ESC switching frequency for motors with more than 2 poles, e.g. out-runners.
Although 16 kHz is more efficient withour Thrust motors, the setup
default is 8 kHz due to the higher RF noises caused at 16 kHz.
10. Low Voltage Cutoff Type: Reduce Power / Hard cutoff
* Reduce Power — ESC reduces motor power when the pre-set (recommended).
* Hard Cutoff — ESC instantly cuts motor power when the pre-set Low Voltage Protection Threshold value is reached.

Using Your New ESC
Improper polarity or short circuit willdamage the ESC therefore it is your responsibility to double check all plugs for
proper polarity and firm fit BEFORE connecting the battery pack.
Alert Tones
The ESC is equipped with audible alert tones toindicate abnormal conditions at power up.
If the ESC can’t enter into working mode after powering up, indicates that you have not setup throttle calibration.
1. Continuous beeping tone (****) — Indicates that th rottle stick is not in the minimum position.
2. Single beeping tone followed by a one second pause (* * * *) - Indicates that the battery pack voltage is not
within the acceptable range. (The ESC automatically checks and verifies the battery voltage once the battery is
3. A single beeping tone followed by a short pause (* * * *) — Indicates thathe ESC is unable to detect the
normal throttle signal from the receiver.
Built-in Intelligent ESC Safety Functions
1. Over-heat protection: When the tem perature of ESC exceeds 110 deg C, the ESC will reduce the output power to
allow it too cool.
2. Lost Throttle signal protection: The ESC will automatically reduces output power to the motor when it detects a lost
of throttle signal for 2 second, asubsequent loss of throttle signalbeyond 2 seconds, will cause the ESC
automatically to cut power to the motor.
Powering up the ESC for the first time and setting the Automatic Throttle Calibration
The ZTW ESC features Automatic Throttle Calibration to attain the smoothest throttle response and resolution
throughout the entire throttle range of your transmitter. This step is done once to allow the ESCto “learn and
memorize” your Transmitter s throttle output signal s and only repeated if you change your transmitter.
1. Switch your Transmitter ON and set the throttle stick to its maximum position.
2. Connect the battery pack to the ESC. Wait for about 2 seconds, the motor will beep for twice, then put the throttle
in the minimum position, the motor will also beep, which indicates that your ESC has got the signal range of the
throttle from your transmitter.
The throttle is now calibrated and your ESC is ready for operation.
Normal ESC start up procedure:
. Switch your TransmitterON and set the throttle to its minimum position.
2. Connect the battery pack the ESC. | | BE
3. When the ESC is first powered up, it emits two sets of audible tones insuccession indicating the status of its
fogramiming state. | ,
* The first set of tones denotes the number of cells in the LiPo pack connected to the ESC. (Three beeps (***)
indicates a 3 cell LiPo pack while 4 beeps (****) indicates a 4 cell LiPo pack). ;
* The second set denoting Brake status. One beep (*) for Brake "ON" and two beeps (**) for Brake "OFF" .
*The ESC is now ready for use.
Entering the Programming Mode:
1. Switch your TransmitterON and set the throttle to itmaximum position.
2. Connect the battery pack to the ESC. }
3. Wait until you hear two short beeps (_ _**) confirming that the ESC has now entered the programming mode.
4. If within 5 seconds, the throttle stick is lowered to its minimum position, an audible tone isemitted confirming
that the throttle calibrationsetting has changed. If the throttle stick is left in the maximum position beyond 5
seconds, the ESC will begin the sequence from one function and its associated setting options to another.
(Please refer to the table below to cross reference the functions with the audible tones).
5. When the desired tone for the func tion and setting option is reached, move the throttle stick down to itsminimum
position. ESC will emit two beeps (**)confirming the new setting has been stored.
6. The ESC only allows the setti ng of one function at a time.
Therefore should you require making changes to other functiondisconnect the battery pack and wait 5 seconds
to reconnect the battery and repeat the above steps.
General Safety Precautions
Do not install the propeller (fixed wing) or drive pinion (helicopter) on the motor when you test the ESC
and motor for the first time to verify the correct settings on your radio. Only install your propeller or
pinion after you have confirmed that the settings on your radio is correct.
Never use ruptured or punctured battery cells.
Never use battery packs that are known to overheat.
Never short circuit battery or motor terminals.
Always use proper insulation material for cable insulation.
Always use propercable connectors.
Do not exceed the number of cells or servos specified by the ESC.
Wrong battery polarity will damage the ESC and void the warranty.
« Install the ESC in a suitable location with adequate ventilationfor cooling. This ESC has a built-in over heat cutoff
protection feature that will immediately cut power to the motor once the ESC temperature exceeds the 230 Deg
F/ 110 Deg C high temperature limit.
Use only batteries that are suppor ted y the ESC and ensure the correct polarity before connecting.
Switch your Transmitter ON and ensure t he throttle stick is in the minimu m position before connecting the battery
Never switch your transmitterOFF while the battery is connected to your ESC.
Only connect your battery pack just before flying anddo not leave your battery pack connected after flying.
Handle your model with extreme care once the battery pack is connected and keep away from the propeller at all
times. Never stand in-line or directlyin front of any rotating parts.
Do not immerse the ESC underwater while powered up.
Do fly at a designated flying site and abide by the rules and guidelines set by your flying club.
