ZTW 20A ESC 2S-4S SBEC ESC Beatles For UAV VTOL And Fixed Wing Aircraft

Product Overview: ZTW Beatles G2 20A 2-4S SBEC G2

ZTW Beatles G2 20A 2-4S SBEC ESC for UAV, VTOL and Fixed-Wing Aircraft

32-Bit Processor for Precise Small-Scale Control

Built around a 32-bit microprocessor, the Beatles G2 20A processes throttle signals quickly and accurately, giving beginner and intermediate pilots smooth, predictable power delivery on lightweight foam trainers and micro fixed-wing aircraft — ideal for first-time builders learning to fine-tune throttle response.

Compact, Lightweight Footprint

At just 60×25×9.5mm and 25g, this ESC is sized for small airframes where every gram matters. The 18-gauge power leads keep wiring flexible without adding bulk, making it a natural fit for park flyers, gliders with power pods, and lightweight 3D foamies.

Reverse Thrust for Short-Field Landings

Like the rest of the Beatles G2 lineup, the 20A supports the SMR reverse-thrust function, letting pilots flip motor rotation below 50% throttle to shorten rollout on grass strips or tight runways — a feature rarely found on ESCs at this size and price point.

Adjustable SBEC Output

The 5V/6V adjustable SBEC delivers up to 4A, enough to power a couple of standard digital servos on small fixed-wing models without a separate receiver battery, simplifying the build and reducing overall aircraft weight.

Multi-Platform Programming

Parameters can be tuned via transmitter stick programming, the ZTW LCD Program Card G2, or the ZTW Bluetooth Module and mobile app (both sold separately), so pilots can adjust brake force, cutoff voltage, and timing without needing advanced tools.

Comprehensive Protection Circuitry

Built-in low-voltage cutoff, over-temperature protection, start-up protection, motor phase-loss detection, and signal-loss protection guard the ESC and battery pack against common flight-line mistakes — particularly valuable for pilots still building experience with LiPo power systems.
