The SkyRC Differential Hardness Tester is an essential tool for modeling enthusiasts looking to fine-tune and reproduce with precision the hardness of their differentials. Designed for 1/8-scale cars (adapter sold separately), 1/10, and Mini-Z (adapter sold separately), this device provides precise numerical data, eliminating the approximations based on feel when adjusting the differentials.

Featuring a one-piece machined aluminum housing with an anodized finish, the SkyRC Differential Hardness Tester blends lightness and robustness. Its compact dimensions of 54 x 28 x 24.8 mm and a weight of only 59 g make it a highly portable tool, ideal for field adjustment sessions. The device is powered via a standard Micro USB port, allowing it to be plugged directly into a power adapter or a portable battery, thus offering great flexibility of use.

The use of the SkyRC Differential Hardness Tester is simple and quick. It is enough to connect the device to a power source, fix the differential to be tested using the provided adapter (1/10 adapter supplied), then press the power button. In a few seconds, a numerical value appears, representing the hardness of the tested differential. This method allows easy comparison of different settings and to reproduce specific configurations with high precision.

The device comes with an adapter for 1/10-scale differentials. An additional adapter for 1/8-scale models or the Mini-Z is available as an option, thereby broadening the tool's compatibility to a wider range of vehicles. It is recommended to carry out tests under similar temperature conditions, as the viscosity of differential oil can be sensitive to thermal variations, thus influencing the measurements obtained.
