Overview
The Hobbywing Skywalker 120A V2 is a Single ESC for brushless (BL) RC fixed-wing aircraft, supporting 3-8S LiPo input and featuring reverse brake modes for landing distance control.
Key Features
- Proven technology: 32 bit ARM M4 chipset, up to 120 MHZ and 300000 RPM (for 2 Pole motors); described as providing great flexibility for a 60-67*3D fixed wing motor.
- DEO Technology / Active Freewheeling: Driving Efficiency Optimization with stated benefits including fast and smooth throttle response, better stability and flexibility during flight, lower ESC temperatures, and longer flight time. (For 3D extreme flying, it is recommended to turn off this function.)
- Reverse Brake: Reverse Brake and Linear Reverse Brakes mode; Normal Brake Mode and Brake Disabled mode are also available; brake amount is adjustable in normal brake mode.
- Search Mode: Can activate the ESC to emit an audible beeping tone from the motor to help locate a craft.
- Multiple protections: Abnormal input voltage, ESC thermal, throttle signal loss (or Fail Safe), and low voltage cutoff.
- Programmable: Programmable with the LED Program Box or transmitter (LED Program Box supported; transmitter supported).

Details

The Skywalker V2 120A ESC features a finned aluminum heat sink and clearly labeled wiring for straightforward installation.

A 32-bit ARM M4 (120MHz) control chip supports high operating frequency and responsive motor control.

Hobbywing’s DEO Technology (Active Freewheeling) is intended to improve driving efficiency and help keep ESC temperatures lower for longer flights.

Reverse brake, linear reverse brake, and normal brake modes provide adjustable braking options for RC aircraft landings.

The Hobbywing Skywalker 120A V2 UBEC ESC includes a Search Mode that triggers an audible motor beeping tone to help locate a lost model.

Skywalker V2 ESC settings can be adjusted for brake type and force, voltage cutoff, LiPo cell count, start-up mode, timing, and search mode.

The Hobbywing Skywalker ESC includes protection features for abnormal input voltage, low-voltage cutoff, ESC thermal, and throttle signal loss.

Skywalker ESC features a large heatsink and a clearly labeled 3–8S LiPo range with selectable BEC outputs from 5V to 8.4V at 10A.

The Hobbywing Skywalker 120A V2-UBEC ESC uses a finned aluminum heatsink case and pre-wired power leads for straightforward installation.

The Skywalker 120A UBEC single ESC features a vented housing and clearly labeled body for straightforward wiring in RC setups.
