ZTW Beatles G2 40A 2-4S SBEC ESC for UAV, VTOL and Fixed-Wing Aircraft
Sized for Sport and 3D Flying
Stepping up to a 68×25×10mm, 37g housing, the Beatles G2 40A is built for mid-size sport aerobatic and 3D fixed-wing aircraft that pull more sustained current than park flyers — think .40-.60 size electric conversions and larger foam 3D models.
40A Continuous / 55A Burst Headroom T
his model gives pilots meaningful burst headroom above its continuous rating, useful for hard vertical pulls and snap maneuvers in 3D flying where current draw spikes briefly above cruise levels.
14-Gauge Power and Motor Leads
Both power and motor wiring step up to 14-gauge at this current level, keeping resistive losses low and reducing heat at the bullet connectors during extended full-throttle 3D routines.
Reverse Thrust for Precision Landings
The SMR function lets pilots switch motor direction below 50% throttle for reverse-thrust braking, shortening landing rollout — a genuine advantage for 3D pilots practicing spot landings on shorter strips.
Adjustable SBEC for Multi-Servo Setups
The 5V/6V adjustable SBEC delivers up to 4A, sufficient for 3-4 lightweight digital servos on typical 3D or sport aerobatic wings, keeping the power system simple without an external BEC.
Field-Programmable via Multiple Methods
Tune throttle response, brake strength, cutoff voltage, and SMR settings through transmitter stick programming, the ZTW LCD Program Card G2, or the Bluetooth Module and app — whichever fits the pilot's existing setup.
Multi-Layer Protection
Startup, over-temperature, low-voltage cutoff, phase-loss, and signal-loss protections are all built in, helping the ESC withstand the more demanding throttle cycles typical of aerobatic and 3D flying without compromising reliability.
