Product overview
The HOBBYWING RTF 65A 4in1 6S Lite AT is a propulsion-control component for FPV drone builds. Its four-in-one architecture combines an F421 main controller with MOSFET switching components, while immersion gold-plated through-hole pads provide the soldering interfaces. HOBBYWING lists 65A continuous and 80A peak for each of four channels, with the overview describing the peak as burst current. These are ratings to confirm for the selected configuration when assessing the intended motor and battery combination.
For installation planning, the published dimensions are 44 × 42 × 5.86mm and the listed weight is 15g; confirm both against the selected configuration. The application range covers FPV frames with a 130–300mm wheelbase. Frame connection points incorporate damping grommets. Power input uses one red and one black 12AWG wire, each 130mm long, with no input connector listed. Motor outputs use solder tabs without supplied output wires, and the ESC signal interface is specified as 8Pin-SH1.0.
The specification table lists self-developed 32-bit firmware, BLHeliSuite configuration support, PWM and DShot300/600 throttle signals, and a 48kHz driving frequency setting. The overview also identifies compatibility with proprietary or AM32 firmware, so procurement should confirm the supplied firmware. Bidirectional DShot supports RPM filtering through the flight controller’s PID tuning page once enabled. A high-frequency, low-ESR capacitor is included, but its described filtering function requires soldering it to the power leads. Wiring and software setup therefore remain integration tasks.
