ZTW Beatles 30a ESC 2S-4S SBEC 30A Electronic Speed Controller
The ZTW Beatles G2 30A ESC steps up power for sport foamies, small scale warbirds, and park-flying fixed-wing models on 2-4S LiPo. 32-bit MOSFET design, adjustable SBEC, and full protection — a reliable step above entry-level ESCs.
Product Overview: ZTW Beatles G2 30A 2-4S SBEC G2
ZTW Beatles G2 30A 2-4S SBEC ESC for UAV, VTOL and Fixed-Wing Aircraft
32-Bit MOSFET Design for Cleaner Power Delivery
The Beatles G2 30A pairs a 32-bit microprocessor with new-generation MOSFET technology, reducing heat buildup under sustained load and giving sport and scale fixed-wing pilots a steadier throttle curve than older 8-bit ESC designs.
Built for Growing Power Demands
With 30A continuous / 40A burst current on 2-4S LiPo or LiHV, this model suits slightly larger airframes than the 20A — park-flying scale models, small aerobatic planes, and sport foamies that need more headroom without stepping up to a heavier ESC.
16-Gauge Wiring for Higher Current Handling
Compared to the 20A's 18-gauge leads, the 30A uses thicker 16-gauge power wire to handle the increased current draw safely, reducing voltage drop and heat at the connectors during hard climbs and full-throttle passes.
SMR Reverse Thrust Function
Supports dynamic motor-direction switching for reverse-thrust braking on landing, helping shorten rollout distance on grass or short runways — useful for pilots flying from smaller fields.
Flexible SBEC Power
The adjustable 5V/6V SBEC supplies up to 4A, enough to run 2-3 mid-torque digital servos directly from the ESC, eliminating the need for a separate UBEC on most park-scale builds.
Multi-Platform Tuning
Program brake force, cutoff voltage, timing, and SMR settings via transmitter stick, the ZTW LCD Program Card G2, or the Bluetooth Module app — giving pilots field-ready flexibility without a laptop.
Full Protection Suite
Low-voltage cutoff, over-heat protection, start-up protection, phase-loss detection, and signal-loss protection are all built in, protecting both the ESC and connected motor from common setup or flight-line errors.
