Cyclone 35A 2–5S BLHeli_S DSHOT600 OPTO ESC

The Cyclone 35A OPTO ESC is a single brushless motor controller for FPV and RC drone builds using 2–5S batteries. It suits builders replacing an individual ESC or creating a custom power system rather than using a 4-in-1 board.

Key features

• 35 A continuous current rating for 2–5S power systems.
• BLHeli_S firmware supports DSHOT600 motor-control signalling.
• OPTO design has no BEC, so it does not supply regulated power to the flight controller or receiver.
• Use a separate BEC or suitable regulated supply when your electronics require one.

Specifications

• ESC Current: 35 A
• Input Voltage: 2–5S
• ESC Firmware: BLHeli_S
• Brand: Cyclone

Because it is an OPTO ESC, the rest of the build must provide regulated power for low-voltage electronics. Confirm the signal wiring and complete propulsion-system voltage and current limits before flight.
