Product overview
The HOBBYWING XRotor FPV G2 45A 4in1 ESC & XRotor FC F7 Combo combines a four-in-one electronic speed controller with an XRotor Flight Controller F7 for FPV racing-drone builds. Its configuration pairs the ESC’s four current-rated channels with a separate flight-controller component. The ESC carries product number 30902045 and a continuous-current specification of 45 A × 4. Its battery requirement is 3–6S LiPo, making cell count a defined constraint when selecting the electrical configuration.
Airframe integration is described through wheelbase-based applications: the ESC is intended for 130–300 mm FPV racing drones, while the F7 controller’s application extends to drones with a wheelbase of 300 mm or less. A repeated controller entry specifies 300 mm. Component identification has an ambiguity: the F7 carries number 31003002 in one entry and 30902045 in another, with the latter also identifying the ESC. The combo is an electronics pairing for integration into a drone.
