HOBBYWING SKYWALKER 20A V1 Speed Controller
Brand: Hobbywing. Category: Drones & Quadcopters > Stacks (FC+ESC).
The HOBBYWING SKYWALKER 20A V1 is a compact and reliable electronic speed controller (ESC) ideal for small and medium-sized RC models. Although this model belongs to a previous generation, it retains the basic set of functions essential for modelers: stable current supply, built-in BEC for powering the receiver and servos, protections, and programmability for specific tasks.
- Continuous Current: 20 Amperes — suitable for most light electric motors in small models.
- Peak Current: up to 25 Amperes in short-term mode, providing extra power reserve during acceleration.
- BEC: integrated Battery Eliminator Circuit with 5 V and 2 A output for powering model electronics.
- Input Voltage: compatible with 2S–3S LiPo batteries, offering flexibility in battery choice.
- Dimensions: approximately 42x25x8 mm, compact housing facilitates integration into the model's chassis.
- Weight: low weight, sufficient to maintain balance and minimize impact on the model's flight characteristics.
- Protections and Features: built-in overcurrent and overheat protection, support for braking function, and adjustable start mode for smooth and safe motor acceleration.
- Programming: controller parameters can be changed using a dedicated programmer or via software on a computer, allowing optimization for a specific model and control style.
