Hobbysky 30A Brushless Electronic Speed Controller (ESC) with 5V/2A BEC

The Hobbysky 30A Brushless ESC is the essential bridge between your battery, radio receiver, and brushless motor. Designed for mid-sized radio-controlled aircraft and custom hobby projects, this Electronic Speed Controller accurately translates the throttle signals from your transmitter into precise, stutter-free motor rotations. Engineered for durability and consistent performance, it features a heavy-duty heat shrink casing and an internal aluminum heatsink to effectively dissipate heat during aggressive flight maneuvers.

A major advantage of this specific ESC is its built-in 5V/2A Battery Eliminator Circuit (BEC). This internal voltage regulator steps down your main flight battery's voltage to a safe 5 volts, supplying continuous power directly to your radio receiver and micro servos. This completely eliminates the need to carry a heavy, separate receiver battery on board, streamlining your wiring and maximizing your aircraft's payload capacity.

Key Features & Functional Advantages:

• 30A Continuous Power: Safely handles a constant 30 Amps of current with short 40-Amp burst capabilities (up to 10 seconds), providing the overhead needed for rapid climbs and emergency evasive maneuvers.

• Integrated 5V/2A BEC: Powers your flight receiver and up to 3 or 4 standard micro servos (like the SG90) directly from the main flight battery, saving crucial weight and interior fuselage space.

• Multiple Safety Protections: Features a robust suite of automatic safety protocols, including low-voltage cut-off (to prevent permanently damaging your LiPo battery), thermal over-heat protection, and throttle signal loss protection (shutting off the motor if radio contact drops).

• Safe Power-On Arming: Built-in safety logic prevents the motor from suddenly spinning up when the battery is plugged in, regardless of where your transmitter's throttle stick is positioned.

• Smooth Throttle Linearity: Delivers an exceptionally smooth, highly linear throttle response, allowing for precise RPM control during slow-speed passes and smooth landings.

Perfect For:

• Fixed-Wing RC Airplanes: The standard, go-to speed controller for popular 800mm to 1200mm wingspan foam board scratch builds, trainers, and park flyers.

• 450-Class RC Helicopters: Provides the rapid throttle response and reliable BEC power required for mid-sized 3D aerobatic helicopters.

• RC Airboats & Hovercrafts: An excellent, cost-effective choice for custom surface vehicles driven by high-KV brushless outrunner motors.

• DIY STEM Robotics: A simple, easily programmable ESC for student engineering projects requiring variable speed control of brushless DC motors.
