8A BEC ZTW Mantis 125A SBEC G2 For 110mm EDF Giant 3D Competition RC Airplane
The ZTW Mantis 125A SBEC G2 is a 32-bit ESC delivering 125A continuous and 135A burst on 3-8S LiPo. At 88×38×24mm and 127g with 6/7.4/8.4V adjustable 8A BEC, synchronous rectification, firmware upgrade, real-time data, and XT90 for 110mm EDF and giant-scale 3D airplanes.
ZTW Mantis 125A SBEC G2 32-Bit ESC 3-8S with 8A BEC for 110mm EDF, Giant 3D and Competition RC Airplane
125A Flagship SBEC for Giant-Scale Power
The Mantis 125A is the most powerful SBEC model in the Mantis lineup, delivering 125A continuous on 3-8S in a 127g package — built for 110mm+ EDF jets, giant-scale 3D aerobatic aircraft, and competition-level airplanes.
125A Continuous / 135A Burst on 3-8S
125A sustained and 135A peak through 10-gauge wires drives the largest EDF units and high-power outrunners with massive current headroom for sustained full-throttle flight.
Compact 88mm Footprint, High Current Density
Despite the 125A rating, the Mantis 125A retains the same 88×38×24mm footprint as the 85A/105A — exceptional current density for space-constrained giant-scale and jet installations.
32-Bit Processor & Synchronous Rectification
The 32-bit MCU with auto timing delivers precise control across the 3-8S range. Synchronous rectification and kinetic energy recovery maximize efficiency and minimize heat under extreme loads.
6/7.4/8.4V Adjustable 8A BEC
The 8A BEC at selectable 6/7.4/8.4V handles multiple high-torque HV servos on giant-scale control surfaces without an external BEC.
Firmware Upgrade & Live Data
APP firmware updates and real-time monitoring of current, voltage, temperature, RPM, and throttle — essential for tracking high-power setups and optimizing gear ratios.
Programming & Protections
Transmitter/LCD G2/APP programming, soft/normal acceleration, RVS braking. Six protection layers. Pre-soldered XT90 and 4mm gold bullets.
