Waterproof, Rustproof & Anti-corrosive

The ESC which features the injection-molded waterproof heatsink housing and the motor consists of the imported waterproof NSK bearings, shaft with patented waterproof structure, anti-corrosive windings (went through vacuum dip coating treatment for twice), stator core (went through electroplating rustproof and anti-corrosive treatment), and rotor magnet steel (went through nickel-copper-nickel electroplating rustproof and anti-corrosive treatment) make the combo waterproof to IPX7 standard. All the protective design effectively guarantees the excellent waterproof, rustproof and anti-corrosive feature of the power system combo.

Data-logging & Multiple Protections

The ESC outputs "black box" data to monitor the power system's operation, record trajectories, discover potential issues and activate corresponding protections in real time for helping flight controller control the system effectively. Multiple protection functions like power-on self test (for detecting internal faults), voltage, current and motor lock-up perfectly protect the system from all the possible risks. (Note: Output data contains input throttle, output throttle, RPM, input voltage, input current, output current, capacitor temperature, MOSFET temperature and etc.)

Light & Compact Design

The compact and light design makes the ESC more applicable to heavy-duty drones (with over 4 rotors), the reserved threaded holes and slots on the heatsink housing simplify and diversify the installation.

Optimized FOC Power System

When pairing with the balanced motor (went through the sine-wave EMF optimization) and propeller, the ESC adopted the latest FOC sine wave-driven algorithm will generate (30%) less heat, have rapider response, and make the drone more stable than traditional sine wave-driven ESCs. The FOC solution greatly improves the battery's sustainability, increases the flight time and effectively protects the motor and battery and prolongs their service lives via current control.

Low Vibration & Noise

The precisely balanced rotor guarantees users low vibration and noise during the motor's high-speed rotation.

High-efficiency Heat Dissipation Structure

Besides the layered structure design, heat-conductive copper bars and heatsink are fitted together to quickly transfer all internal heat to the integrated heatsink housing of the ESC. The centrifugal fan design adopted by the motor rotor can autonomously dissipate heat in operation. All this will effectively improve the flight performance of the drone.

Triple Interlocking Design

The HOBBYWING patented interlocking structure design (that’s the circlip or snap ring, lock sleeve, and screw) implemented by the motor rotor guarantees the great stability and reliability of the motor.

Strong Impetus

The 23-inch precisely molded propeller which is made of some light and solid composite material has great strength, stiffness and excellent shape (which guarantees the minimum air friction in operation). It's impact-resistant, anti-abrasive, collapsible (with blades are replaceable) and can produce the thrust of up to 12kg when combining with the optimized motor's electromagnetic design and the high-efficiency ESC's FOC algorithm.

Impact-resistant & Heat-resistant

The alloy shaft combined with overall reinforced CNC-machined rotor guarantees the high impact resistance, the special heat-resistant windings combined with heat-resistant magnets guarantees the powerful and continuous overload capability, and the wear-proof rubber sleeve which is designed to protect and fix the motor wires guarantees the durability & reliability of the motor.

Regular Firmware Updates Free of Charge

You can upgrade the ESC with the Hobbywing USB LINK software, a LCD program box (item sold separately) and a laptop. Hobbywing updates its ESC firmware regularly giving you upgraded features more often when available.
