FETTEC FT-4ESC1-65A 4in1 ESC 65A G4 Flight Controller

Introduction

Thank you for purchasing the FETtec 4in1 ESC 65A.

Features

• Active current limiting @ 65A
• Input voltage: 3S 8S
• High qu ality 40V MOSFETs
• STM32G071 @ 64MHz
• 128 kHz Motor PWM
• Automatic input signal detection
  • Dshot 300 2400
  • PWM
  • OneShot 42/125
  • Onewire
  • S2M
• KISS FC Passthrough
• Betaflight Passthrough

Safety warning

• Remove propeller before flashing and configuration!
• The ESC can heat up to 100°C and more
• Please ensure that there is enough space and airflow to prevent any damage because of overheating
• Please check periodically for firmware updates in the FETtec Configurator
• Do not file the mounting holes as this may cause damage.

• TLM:  Telemetry (Serial)
• GND:  Reference Signal Ground
• Bat+: Battery+

Connection to FC

4-6S

For usage an additional capacitor with the following specification is required.

• Minimum 470uF
• 50V
• ESR < 1ohm

We recommend to use the provided capacitor which comes with the ESC.

Note: A bigger cap with only 35V might not suffice.

8S ****

• Its necessary to use the cap
• The used FC must be able to run on 8s.
• The FETtec FCs need an extra BEC

FETtec FC

• Use the 8pin cable which comes with the FETtec 4in1 ESC 65A to connect it to the FETtec FC
• (It is possible to use 2 ESCs for a build with more than 4 motors. If you only use 4 motors, please use the connector 1)

Betaflight FC

Connection

• Signal 1- 4 have to be connected to the corresponding FC Motor outputs.
• The TLM wire has to be connected to an available serial TX pin.

Configuration

In order to utilize ESC provided current and voltage sensor the following settings need to be applied to Betaflight. (Feature, motor protocol and meter can be configured through the GUI itself). In addition, the correct serial port need to be selected and assigned to ESC sensor.

• feature ESC_SENSOR
• set motor_pwm_proto col = DSHOT600
• set current_meter = ESC
• set battery_meter = ESC
• set esc_sensor_halfduplex = ON

FETtec Configurator

Please update your ESC periodically with the current Firmware version.

• The ESC configuration tool is available at https://gui.fettec.net/ESC/index.html
• The ESC firmware is available in remote or for download at https://github.com/FETtec/ESC-Firmware

FC passthrough is available for the following platforms

• KISS FC Firmware 1.3 RC36j (or higher)
• Betaflight 4.1 firmware (Minimum requirement for Onewire is STM32F4)

Settings

• Mainpage to connect to the ESC. Please select correct connectivity type and serial/COM port.
• The Overview page allows to flash individual ESCs

The Setting page allows to adjust all available ESC parameter

• Reverse rotation direction

• Slow start

• 3D mode

• PWM min & max signal

• ESC Beep enabled

• Current calibration

• Individual ESC ID (for use on onewire protocol)

• In Telemetry page you can spin the motors, view and debug the Motor telemetry.

Dimension (in mm)

• Maximum outside dimensions: 38 x 48mm
• Mounting hole arrangement: 30,5 x 30,5mm with M3 mounting hole (expandable to M4)
• Weight: 13,6g
• You can use a screw driver and force it into M4 by rotating it inside the hole carefully.
• Do not file the mounting holes as this may cause damage
