The speed controller can be connected to the motor by soldering directly or with high quality connectors with a minimum diameter of 4mm. Always use new connectors, which should be soldered carefully
to the cables and insulated with heat-shrink tube. Only used "Leaded Solder"
I. Wires Connection
◆
Solder suitable connectors (mating halves to those fitted to your motor) to the ESC motor wires.
◆
Solder suitable connectors to the battery connecting wires on the ESC.
◆
Insulate all connectors with heat shrink tubing.
◆
Plug the long “servo” type wire/connector into the receiver's throttle channel.
◆
When ready to fly, connect the main Red and Black wires on the ESC to your battery pack paying close attention to polarity.
II. ESC Features
◆
Uses new generation of MOSFET to ensure high efficiency and low heat.
◆
Easy to program by 4-Max HV Programming box.
◆
Advance governor mode keeps the motor speed constant when the load on the motor changes
◆
5 motor timing options and soft acceleration start-ups make the motors run smoothly
◆
Super smooth and accurate throttle linearity
◆
Supports high RPM motors.
◆
Power arming protection (prevents the motor from accidentally running when switched ON)
◆
Built-in Intelligent ESC Safety Functions:
1. Over Temperature 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 throttle signal loss for 2 second, a subsequent loss of throttle signal beyond 2
seconds, will cause the ESC automatically to cut all power to the motor.
◆
All functions are programmable to meet your specific needs.
III. Setting
1. Brake Type (Brake Off/Soft Brake/Mid Brake/Hard Brake)
* Brake off ─Set the propeller to freewheel when the throttle stick is at the minimum position.
* Soft Brake ─Set the propeller to 30% of the brake position when the throttle stick is at the minimum position (Recommended for folding props and some aerobatic aircraft).
* Mid Brake ─Set the propeller to 60% of the brake position when the throttle stick is at the minimum position (Recommended for folding props and some aerobatic aircraft).
* Hard Brake ─Set the propeller to 100% of the brake position when the throttle stick is at the minimum position (Recommended for folding props).
2. Battery Type (NiCd or NiMh/LiPo/LiFe)
* NiCd/NiMh ─Set Low voltage protection threshold for NiCd / NiMh cells.
* LiPo ─Set Low voltage protection threshold for LiPo cells and automatically detects the number of cells within the pack.
* LiFe ─Set Low voltage protection threshold for LiFe cells.
Note: Selecting the NiCd/NiMh option for the battery type, triggers the ESC to automatically set the cut off threshold to the factory default of 60%. The cut off threshold can then be subsequently altered
through the Low Voltage protection function, if required. The ESC will read the initial voltage of the NiCd/NiMh pack once it is plugged in and the voltage read will then be used as a reference for the cut
off voltage threshold.
3. Cut off Voltage Threshold (Low Voltage Protection Threshold)
Low(2.8V/50% )/ Medium(3.0V/60%)/ High(3.2V/65%)(recommended)/ No Protection
* For Li-xx packs ─number of cells are automatically calculated and requires no user input apart from defining the battery type. This ESC provides 4 setting options for the low voltage protection
threshold; Low (2.8V)/ Medium (3.0V)/ High (3.2V)/No protection. For example: the voltage cut off options for an 11.1V/ 3 cell Li-Po pack would be 8.4V (Low)/ 9.0V(Med)/ 9.6V(High).
* For Ni-xx/LiFe packs ─low/medium/high cut off voltages are 50%/60%/65% of the initial voltage of the battery pack. For example: A fully charged 6 cell NiMh pack’s voltage is 1.44V×6=8.64V,when
“LOW” cut off voltage is set, the cut off voltage is: 8.64V×50%=4.3V and when “Medium” of “High” is set, the cut off voltage is now 8.64V×65%=5.61V.

5. Motor Timing (to enhance ESC efficiency and smoothness) Auto/2°/8°/15°/22°/30°
Auto ESC determines the optimum motor timing automatically
2°, 8° For most inrunner motors.
15°, 22° For motors with 6 or more poles.
30° For most outrunners
Automatic timing works well for most types of motors. However for high efficiency we recommend the Low timing setting for 2 pole motors (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 for a short period on the ground first after making any changes to your motor timing!
6. SBEC Voltage Output (5V/5.5V/6V)
Note: This is not applicable as it is an OPTO ESC and therefore does not have any SBEC built in.
7. Governor Mode-for heli. (RPMOFF/ 1st Soft Start / 2nd Soft Start / Governor Mode 1 / Governor Mode 2)
* RPM off: Rpm control off
* Soft Start For 1st soft-start, there will be a 8-second delay from start to full rpm. For 2nd soft-start, there will be a 18-second delay from start to full rpm. Note: If the throttle is cut off after
starting less 3 Seconds, then the next start will be as normal start. If the throttle is cut off after starting more than 3 Seconds, the next start will be as soft start.
* Governor Mode Governor Mode 1: There will be a 2-3 second delay from start to full rpm; If lower the throttle to the 80% position of the full throttle or lower than 80% position, the RPM would be
definitely changed , the lost RPM will be detected and compensated automatically by the ESC that makes sure to keep the RPM at the same speed. (Note: This function is only
for Low KV motor)
* Governor Mode 2: There will be a 2-3 second delay from start to full rpm; If lower the throttle to the 80% position of the full throttle or lower than 80% position, the RPM would
be definitely changed , the lost RPM will be detected and compensated automatically by the ESC that makes sure to keep the RPM at the same speed. (Note: This function is
only for High KV motor)
Note1: If the throttle is cut off after starting less 3 Seconds, then the next start will be as normal start. If the throttle is cut off after starting more than 3 Seconds, the next start will be as soft start.
