Holybro Tekko32 F4 Metal 4in1 65A ESC (65A)
Holybro Tekko32 F4 Metal 4in1 65A ESC (65A)
The Holybro Tekko32 F4 Metal 4in1 65A ESC is a high-performance integrated electronic speed controller designed for multi-rotor UAVs, racing drones, and FPV quadcopters requiring synchronized motor control with advanced firmware capabilities. Professional drone pilots, FPV racers, and commercial UAV operators utilize this ESC for its robust 65-ampere continuous current handling and integrated F4 flight controller compatibility. This 4-in-1 configuration solves the complexity of managing multiple discrete ESCs by consolidating four independent motor controllers into a single compact unit, reducing weight, wiring complexity, and potential points of failure in high-performance aerial platforms.
Product Overview
The Tekko32 F4 Metal represents a significant advancement in integrated ESC technology, combining four independent 65-ampere motor controllers with DShot protocol support, enabling real-time bidirectional communication between the flight controller and each motor simultaneously. The metal construction provides superior heat dissipation compared to plastic variants, critical for sustained high-current operations in racing and acrobatic flight profiles. Each of the four channels operates independently with dedicated MOSFETs and filtering circuits, allowing asymmetric load distribution and precise individual motor speed control essential for aggressive flight maneuvers and rapid response dynamics.
The ESC firmware supports multiple protocols including PWM, OneShot, MultiShot, and DShot (150, 300, 600, 1200), providing compatibility with virtually all modern flight control systems while future-proofing your investment. The integrated BLHeli_32 firmware delivers smooth throttle response, active freewheeling for reduced vibration, and comprehensive telemetry feedback including current draw, voltage monitoring, and temperature sensing on each motor channel. The metal housing acts as a heat sink with thermal interface pads, maintaining optimal operating temperatures during extended high-power flights typical in FPV racing circuits and professional cinematography operations.

How to Use
Installation begins with identifying the motor phase wires and ESC output connections on your flight controller. The Tekko32 F4 provides four independent motor outputs labeled M1, M2, M3, and M4, which must be connected to your flight controller's corresponding motor ports in the correct sequence to match your frame configuration (X-quad, H-quad, or custom geometry). Connect the battery input (positive and negative) to the designated battery pads with proper XT60 or XT90 connectors, ensuring polarity is correct to prevent component damage. The integrated BEC outputs (5V and 3.3V) should power your flight controller and receiver; verify current draw does not exceed 2-3 amperes per BEC output to prevent thermal shutdown.
Configuration requires connecting your flight controller to a computer via USB and using Betaflight, iNav, or your flight controller's native software to select DShot protocol, configure motor directions, and calibrate ESC endpoints. Access the BLHeli_32 firmware settings through your flight controller's ESC configuration menu to adjust throttle response curves, enable telemetry, and set current limit thresholds based on your motor and battery specifications. After firmware flashing and configuration, perform a static thrust test at 25%, 50%, 75%, and 100% throttle to verify all four motors spin in the correct direction with smooth response before your first flight. Always use a battery eliminator circuit (BEC) or external power supply during bench testing to prevent accidental motor spin-up.
Frequently Asked Questions
What is the difference between DShot 300 and DShot 600 protocols on the Tekko32 F4?
DShot 300 transmits motor commands at 300 kilobaud, updating motor speed 8,000 times per second, suitable for most flight controllers and providing excellent responsiveness for racing applications. DShot 600 doubles the baud rate to 600 kilobaud, enabling 16,000 updates per second with reduced latency, preferred for high-frequency flight controllers (32kHz gyro sampling) and ultra-competitive racing where sub-millisecond response times provide competitive advantage. Your flight controller must support the selected protocol; check your specific flight controller's documentation for maximum supported DShot frequency.
Can I use the Tekko32 F4 on a 2S LiPo battery for lightweight micro drones?
Yes, the Tekko32 F4 supports 2S LiPo batteries (7.4V nominal), though the 65-ampere rating is optimized for 4S-6S configurations. On 2S, you are limited to smaller motors (typically 1105-1306 size) with lower KV ratings to stay within the 65-ampere continuous limit. Verify your motor's current draw at full throttle on 2S does not exceed 16-17 amperes per motor (65A divided by 4 channels) to ensure safe operation without thermal throttling or component damage.
Does the Tekko32 F4 provide motor telemetry feedback to the flight controller?
Yes, when using DShot protocol, the Tekko32 F4 transmits real-time telemetry including individual motor RPM, current draw per channel, and ESC temperature back to the flight controller via the signal line. This telemetry enables advanced flight control features like dynamic notch filtering based on actual motor vibration frequencies, current-based thrust estimation for precise altitude hold, and thermal management alerts if any channel approaches its temperature limit. Enable telemetry in your flight controller's ESC configuration menu to access this data.
