2-4S Mantis 25A SBEC G2 32 Bit ESC Adjustable BEC Mantis ESC
The ZTW Mantis 25A SBEC G2 is a flat 32-bit ESC delivering 25A continuous and 35A burst on 2-4S LiPo. At 68×28×10mm and 36g with 5/6/7.4V adjustable 4A BEC, synchronous rectification, auto timing, and XT60 for sport planes, warbirds and 3D foamies.
Mantis G2 Series: 32-Bit Brushless ESC
ZTW Mantis 25A SBEC G2 32-Bit ESC 2-4S with Adjustable BEC for RC Fixed Wing F3P EDF Jet Mini VTOL Aircraft
10mm Flat ESC for Sport & Scale Airplanes
The Mantis 25A features a slim 10mm flat profile (68×28×10mm, 36g) designed to tuck inside narrow fuselages of sport planes, warbirds, and 3D foamies where a standard ESC won't fit.
25A Continuous / 35A Burst on 2-4S
Delivers 25A sustained and 35A peak on 2-4S LiPo through 18-gauge wires, driving 28-35mm outrunners in sport aerobatic and scale warbird applications.
32-Bit Processor & Auto Timing
The 32-bit MCU with automatic motor timing identification ensures optimal efficiency and broad motor compatibility — no manual timing setup needed when swapping motors.
Synchronous Rectification
Synchronous rectification delivers faster throttle response, lower temperatures, and longer flight times by reducing switching losses.
5/6/7.4V Adjustable 4A BEC
The switching BEC is adjustable between 5V, 6V, and 7.4V at 4A, supporting both standard and HV digital servos without an external BEC.
Normal/Soft Acceleration & RVS Braking
Selectable normal or soft acceleration (soft recommended for EDF), plus motor direction switching with braking reverse for shortened landing rolls.
Triple Programming & Protections
Transmitter, LCD Program Card G2, or APP programming with six protection layers. Pre-soldered XT60 and 3.5mm gold bullets.
