Hobbywing XRotor Pro 40A 2-6S OPTO Mutirotor ESC (Dual Pack)

The Hobbywing X-Rotor Pro series ESC deliver class leading performance in terms of efficiency and reliability, making them our first choice ESC for professional applications. This particular 40A Pro version is suited to heavy lifting multirotors: hexacopters and octocopters. It's rated at 40amps (60amp burst) and supports 2S to 6S (11.1v - 22.2v) operation.

As with all of the X-Rotor ESCs, the 40A Pro has been designed specifically for multirotor use. With their special core program tuned for multirotors, the ESCs have been optimised for compatibility with disc type outrunner brushless motors, which are commonly used on large multirotors. A unique feature of the series is the Driving Efficiency Optimization (DEO) function. This significantly improves throttle linearity and driving efficiency, by automatically braking and quickly reducing the motor speed when decreasing the throttle amount. The effect is increased manoeuvrability and stability of your multi-rotor, with the bonus of improved efficiency too. The high performance of the drive chip is enhanced further by the use of extra low-resistance MOSFETs that also allow high currents to be held stable for longer.

Most flight controllers are compatible with the XRotor Pro series, which supports signal frequencies of up to 621Hz. Furthermore, as all of the settings are pre-set for multirotor use, using the XRotor Pro series couldn't be simpler. Note that the ESC is OPTO, therefore it doesn't have a built in 5V BEC. You will need an extra power source for your receiver. For this you can use a 5V UBEC, voltage regulator, or an extra battery.

The ESCs come with long power and signal wires as standard, which means they can be installed without extensions on even the largest of frames. Finally, thanks to the design of the ESC's heat sink, it is possible to mount them within 25mm tube for a very neat installation.

The ESCs are sold as pairs in a dual pack.
