Manual for Motor and ESC of the Hacker Venus 3D
Manual V1.0
Thank you for purchasing T MOTOR Brushless Electronic Speed Controller (ESC).
The T MOTOR ESC’s high power BEC has been specifically designed for extreme aerobatics and therefore has the
capability to support the higher momentary peak demand loads to eliminate the possibility of unwanted shutdowns, and is
also capable of supporting continuous simultaneous multiple servo operations typically found in CCPM equipped hardcore
3D E-helicopters.
Wires Connection:
The speed controller can be connected to the motor by soldering directly or with high quality connectors. Always use new
connectors, which should be soldered carefully to the cables and insulated with heat shrink tube. The maximum length of
the battery pack wires shall be within 6 inches.
Solder controller to the motor wires.
Solder appropriate connectors to the battery wires.
Insulate all solder connectors with heat shrink tubes.
Plug the “JR” connector into the receiver throttle channel.
Controller Red and Black wires connects to battery pack Red and Black wires respectively.
Features:
- Extremely low internal resistance
- Super smooth and accurate throttle linearity
- Safety thermal over-load protection
- Auto throttle shut down in signal lose situation
- Supports high RPM motors
- Power arming protection (prevents the motor from accidentally running when switched ON)
- New Advanced programming software
Our ESC allows you to program all functions to fit your specific needs,which makes it very efficient and user
friendly:
1.User programmable brake setting (we recommend using brake for only folding props applications)
2.User programmable battery type(LiPo or NiCd/NiMh)
3.User programmable low voltage cutoff setting
4.User programmable factory default setup restore
5.User programmable timing settings (to enhance ESC efficiency and smoothness)
6.User programmable soft acceleration start ups (for delicate gearbox and helicopter applications)
7.User programmable governor mode(for helicopter applications)
8.User programmable motor rotation(clockwise\counterclockwise)
9.User programmable switching frequency
10.User programmable low voltage cutoff type (power reduction orimmediate shutdown)

Settings:
1.Brake: ON/OFF
* ON-Sets the propeller to the brake position when the throttle stickis at the minimum position (Recommended for folding
props).
* OFF-Sets the propeller to freewheel when the throttle stick is at the minimum position.
2.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 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 options for 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 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” of “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 ： 8kHz
Low voltage cutoff type： Reduce power
5.Timing setup : Automatic/ Low / High.
* Automatic – ESC automatically determines 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 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!
6.Soft Acceleration Start ups: Very Soft / Soft Acceleration/ Start Acceleration
* Very Soft – Provides initial slow 1.5 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 acceleration 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 cutoff after starting, then the next
start will be as normal start.
2
* second range: There will be a 15-second delay from start to full rpm, but if the throttle is cutoff after starting, then the

next start will be as normal start.
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.
8.Motor Rotation: Reverse
In most cases motor rotation is usually reversed by swapping two motor wires. However, in cases where the motor cables
have been directly soldered the ESC cables, motor rotation can be reversed by changing the value of setting on the ESC.
9.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.
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 will damage the ESC therefore it is your responsibility to double check all plugs for proper
polarity and firm fit BEEORE connecting the battery pack.
Alert Tones
The T MOTOR ESC is equipped with audible alert tones to indicate abnormal conditions at power up.
If ESC can't enter into working mode after powering up, it indicates that you have not setup throttle calibration.
2. Continuous beeping tone (****) – Indicates that throttle stick is not in the minimum position.
3. 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).
4. 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 exceed 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, 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 T MOTOR 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”
your Transmitter’s throttle output signals 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:
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.
* The first set of tones denotes the number of cells in the LiPo pack connected to the ESC. (2 beeps (**)indicates a 2 cell
LiPo pack while 3 beeps (****) indicates a 3 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 Transmitter ON and set the throttle to its maximum 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 is emitted confirming that the
throttle calibration 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.
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.
