Product overview
HOBBYWING’s RTF 65A 4in1 6S Lite BLS V2 provides four-channel brushless motor control for FPV aircraft. The product is an ESC component, with its application entry covering aircraft of 130–300mm wheelbase. Its electronic architecture uses a BB51 main controller and MOSFETs. Published electrical ratings are 65A continuous and 80A peak per channel, powered by 4–6S LiPo. The description qualifies the burst rating as up to 80A.
The specified envelope is 44 × 44 × 5.86mm, with a listed weight of 15g. These figures provide the starting point for allocating installation space. Signal integration uses an 8Pin-SH1.0 interface. Power input wiring comprises one red and one black 12AWG wire, each 130mm long, with no input connector listed. Motor outputs have solder tabs without wires. The board uses immersion gold-plated through-hole solder pads, and its frame connection points carry damping grommets. A high-frequency, low-ESR capacitor is included and requires soldering to the power leads.
The firmware specification lists Bluejay and BLHeli-S, while the description supports flashing and switching between BLS and Bluejay. Programming is supported, but parameter adjustment depends on the flashed firmware. The throttle-signal entry states Bluejay firmware support, and motor rotation support is also qualified by Bluejay firmware. Listed driving-frequency choices are 24, 48 and 96kHz. Bidirectional DShot and RPM filtering are supported; using RPM filtering requires enabling bidirectional DShot and configuring the flight controller’s PID tuning page. The selected firmware and these installation dependencies therefore need confirmation for the intended aircraft.
