Note: The PA Quantum Pro line has a powerful switching voltage regulator chip which supports the high
torque micro servos in the most demanding load-conditions imposed during aggressive 3D aerobatics,
providing bulletproof reliability. In this form of flying the servos actuating oversized control surfaces and may
stall momentarily under extreme aerodynamic loads. These loads may cause most low and medium power
BECs to overheat and shutdown resulting in catastrophic loss of control.
The Quantum Pro ESC’s high power SBEC has been specifically designed for extreme aerobatics and
therefore has the capability to support the higher momentary peak loads to eliminate the possibility of
unwanted shutdowns. This high power SBEC is also capable of supporting continuous simultaneous multiple
servo operations typically found in CCPM equipped hardcore 3D E-helicopters.
The higher and stable SBEC voltage also reduces the possibility of receiver brownouts that occasionally occur
on some 2.4GHz receivers in instances where conventional linear BECs are subjected to high servo loads
causing the BEC voltage to drop below the voltage threshold required by the 2.4GHz receiver.
Features:
Extremely low internal resistance

Settings:
1.
2.
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 the throttle stick is at the minimum position.
Battery type: LiPo or NiCad/NiMh
NiCad/NiMh - Sets Low Voltage protection threshold for NiCad/NiMh cells.
LiPo - Sets Low voltage protection threshold for LiPo cells and automatically detects the number of cells
within the pack.
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 LiPo 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 options for
an 11.1V/ 3 cell LiPo pack would be 8.4V (Low)/ 9.0V (Med)/ 9.6V (High).
2)
For Ni-xx packs- low / medium / high cutoff voltages are 50%/65%/65% of the initial voltage of
the battery pack. For example: A fully charged 6 cell NiMh pack’s voltage is 1.44V X 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.

Switching Frequency: 8kHz/16kHz
8kHz - Sets ESC switching frequency for 2 pole motors, e.g. in-runners.
16kHz- Sets ESC switching frequency for motors with more than 2 poles, e.g. out-runners.
Although 16kHz is more efficient with our Thrust motors, the setup default is 8kHz due to the higher RF
noises caused at 16kHz.
6.
Low Voltage Cutoff Type: Reduce Power / Hard cutoff
Reduce Power – ESC reduces motor power when the pre-set Low Voltage Protection Threshold value is

reached (recommended).
Hard Cutoff – ESC instantly cuts motor power when the pre-set Low Voltage Protection Threshold value
is reached.
7.
Timing setup: Low / Automatic / High.
* Low (0 – 7deg) - Setting for most 2 pole motors.
* Automatic - ESC automatically determines the optimum motor timing
* High (22-30 deg) - Setting for motors with 6 or more poles.
In most cases, automatic timing works well for all types of 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 setups therefore we suggest you to follow the manufacturer recommended setup or use the
automatic timing setting if you are unsure.
Note: Run your motor on the ground first after making any changes to your motor timing!
8.
Soft Acceleration Start ups: Disable / Soft
Disable – Provides quick acceleration start ups with a linear throttle response. This is recommended for
fixed wing models fitted with direct drive setups.
Soft – Provides initial slow 1 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.
9.
Motor Rotation: Reverse
In most cases motor rotation is usually reversed by swapping two motor cables over. However, in cases
where the motor cables have been directly soldered to the ESC cables, motor rotation can be reversed by
changing the value of this setting on the ESC.
10. Governor Mode: Disable / Enable
Disable- disables the governor mode,
(Helicopter application)
Enable- enables the governor mode.
Note: Once the Governor Mode is enabled, the ESC’s Brake and Low Voltage Cutoff Type settings will
automatically be reset to No Brake and Reduce Power respectively regardless of what settings they were
previously set.
Using Your New ESC
Improper polarity or short circuit will damage the ESC and void warranty therefore it is your
responsibility to double check all plugs for proper polarity and firm fit BEFORE connecting the
battery pack.
Alert Tones
The PA Quantum ESC is equipped with audible alert tones to indicate abnormal conditions at power up.
1. Continuous beeping tone (****) - Indicates that throttle 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 connected).
3. A single beeping tone followed by a short pause (* * * *) – Indicates that the ESC is unable to detect
the normal throttle signal from the receiver.
Built-in Intelligent ESC Safety Functions
1. Over-heat protection: When the temperature of ESC exceeds 110 deg C, the ESC will reduce the
output power to allow it to 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, a subsequent loss of throttle signal beyond 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 PA Quantum 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 ESC to “learn and memorize”

Switch your Transmitter ON and set the throttle stick to its minimum position.
Adjust the throttle trim all the way down to the minimum position.
Verify the throttle travel adjust (ATV) to be set at 100% span.
Disable any throttle mix or curves in the transmitter. (For Futaba radios set the throttle channel to
Reverse)
Connect the battery pack to the ESC.
Adjust your throttle trim up until the motor starts spinning.
Then adjust your throttle trim a few clicks down until the motor stops spinning.
The throttle is now calibrated and your ESC is ready for operation.
Normal ESC start up procedure:
1. Switch your Transmitter ON and set the throttle to its minimum position.
2. Connect the battery pack to the ESC.
3. When the ESC is first powered up, it emits two sets of audible tones in succession indicating the status
of its programming state.
o 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).
o The second set denoting Brake status (one beep (*) for Brake “ON” and two beeps (**) for Brake “OFF”).
o The ESC then automatically calibrates the throttle range.
o The ESC is now ready for use.
Note: Should the audible tone be any different than what is stated above, please refer to the Alert Tones
and Built-in Intelligent ESC Safety Functions section of this manual.
Entering the Programming Mode:
1. Switch your Transmitter ON and set the throttle to its maximum position.
2. Connect the battery pack to the ESC.
3. Wait until you hear two long audible tones followed by 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 is emitted
confirming that the brake setting 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 function and setting option is reached, move the throttle stick down to
its minimum position. ESC will emit two beeps (* *) confirming the new setting has been stored.
6. The ESC only allows the setting of one function at a time. Therefore should you require making
changes to other function, disconnect the battery pack and wait 5 seconds to reconnect the battery
and repeat the above steps.
