2-6S ZTW Mantis 45A SBEC G2 32 Bit RC Airplane ESC With Adjustable BEC
The ZTW Mantis 45A SBEC G2 is a flat 32-bit ESC delivering 45A continuous and 55A burst on 2-6S LiPo. At 73×28×10mm and 45g with 5/6/7.4V adjustable 4A BEC, synchronous rectification, soft EDF acceleration, and XT60 for 6S sport and aerobatic airplanes.
ZTW Mantis 45A SBEC G2 32-Bit ESC 2-6S with Adjustable BEC for 3D Aerobatic, EDF Jet and Sport RC Airplane
45A 6S Capability in a 10mm Flat Case
The Mantis 45A extends the flat-profile Mantis platform to 6S, delivering 45A continuous in a 73×28×10mm, 45g package — ideal for 6S sport aerobatic planes, mid-size EDF jets, and 3D models that need high voltage but cannot accommodate a tall ESC.
45A Continuous / 55A Burst on 2-6S
45A sustained and 55A peak across 2-6S LiPo through 14-gauge wires handles high-KV inrunners and 6S outrunners with authority.
32-Bit Processor & Auto Timing
The 32-bit MCU with automatic motor timing identification delivers optimal drive efficiency and broad motor compatibility across outrunners and EDF inrunners.
Synchronous Rectification
Reduces switching losses for cooler operation and longer flight times — important on 6S setups where power levels and heat are higher.
5/6/7.4V Adjustable 4A BEC
Field-selectable BEC voltage supports both standard and HV digital servos on 6S airframes without an external BEC.
Soft Start for EDF, RVS Braking
Soft acceleration mode protects EDF drivetrains; normal mode for aerobatics. Motor direction switching with reverse braking shortens landing rollout.
Programming & Protections
Transmitter/LCD G2/APP programming. Six protection layers: start-up, over-heat, phase-loss, signal-loss, low-voltage, over-current. Pre-soldered XT60 and 3.5mm bullets.
