Product overview
HOBBYWING positions the XRotor FPV G2 45A 4in1 ESC as a brushless motor-control component for FPV racing. Its board combines four ESC channels, with published continuous and peak ratings of 45A × 4 and 60A × 4 respectively. Procurement scope is an ESC component rather than a flight platform or airframe kit. The stated application range is 100–300mm FPVs, and input power is specified as 3–6S LiPo. No peak-current duration.
For integration planning, the manufacturer publishes a 40 × 33 × 5mm envelope, 12g weight and 20 × 20mm mounting-hole spacing; buyers should confirm these values for their selected configuration. The mounting holes incorporate a shock-absorbing design. Flight-controller connections can use soft cables or solder tabs. The wiring specification lists one red and one black 14AWG input lead, each 100mm long, plus an XT60 connector with wires soldered on. Motor outputs have solder tabs, with no output wires or connectors listed.
The control architecture uses a 32-bit ARM F4 processor with a published 120MHz operating frequency and AM32 XROTOR45 F421 firmware. Listed throttle inputs include DShot 300/600 and traditional PWM. Firmware updates and parameter configuration can use the throttle signal cable, a development board or a Betaflight-compatible flight controller. A significant procurement discrepancy concerns auxiliary power: the specification table says there is no BEC output, while a repeated description claims a 5V BEC. Resolve that conflict before allocating power for attached devices.
