These ESCs are designed to provide dependable performance and exceptional build quality, making them a great choice for FPV drone enthusiasts. In this article, we will take a closer look at the XRotor G2’s features and capabilities, and provide our thoughts on the product. We will also discuss the pros and cons of these ESCs, and answer some frequently asked questions about them.

Features and Capabilities

The Hobbywing XRotor G2 4in1 ESC 45A & 65A are state-of-the-art ESCs that feature an AT32F4 processor, dynamic 128KHz PWM frequency, and a refined overall design. These ESCs are designed to provide dependable performance and exceptional build quality, making them a great choice for FPV drone enthusiasts. At first glance, the XRotor G2 ESCs might seem similar to the previous XRotor Micro ESC in terms of design. The 65A version features a 30x30mm mounting size, while the 45A version offers a 20x20mm mounting size. Each version boasts a 5-amp increase in continuous current rating compared to the previous generation. The XRotor G2 ESCs come with an AT32 F4 processor running at up to 120MHz, which provides fast and reliable processing power. The 3in1 gate driver ensures that the ESCs can handle high current loads without overheating or malfunctioning. The ESCs run the latest BLHeli_32 32.9 Firmware, which provides a smooth and responsive flight experience. The PWM frequency range is between 24kHz and 128kHz with dynamic PWM support, which ensures that the ESCs can handle a wide range of flight conditions. The ESCs support Dshot and other ESC protocols, which makes them compatible with a wide range of flight controllers. The input voltage range is 3-6S, which provides plenty of power for high-performance FPV drones.

Build Quality and Design

Hobbywing ESCs are known for their hardware reliability and resilience in crashes, especially popular among FPV drone racers. The overall quality of the new version looks excellent as expected, with no noticeable issues in soldering or component placement. These ESCs have 13cm silicone wires and low-ESR capacitors pre-soldered to the power pads, which might be convenient for those who dislike soldering. However, you still have to solder the included XT60 connectors, but this allows you to cut the wires to the desired length for your specific build, which makes sense. The soldering quality is exceptional as you can see in these images.The XRotor G2 ESCs have a refined overall design that makes them easy to install and use. The 65A version features a 30x30mm mounting size, while the 45A version offers a 20x20mm mounting size. Each version boasts a 5-amp increase in continuous current rating compared to the previous generation. The ESCs have a sleek and modern look that will complement any FPV drone build.
