The SkyRC Differential Analyzer is a must have tool for setting up and fine-tuning the hardness of differentials for 1/10th scale cars. The Diff Analyzer provides numeric data that helps you replicate a specific hardness, and duplicate your setup after a re-build. No more guessing, no more trying to feel by hand. Now you can get numeric values you can use to measure the diff setting, ensuring consistent hardness after building and setup. Tiny but Versatile The analyzer is powered by any universal Micro USB output or a power bank, weighs just 59 grams and measures 54x28x24.8mm. A precision machined aluminum enclosure creates a thin, durable and aesthetically pleasing design. It includes two 1/10th scale adapters - a hex type adapter for measuring the diff from the wheel nut, and a pin type for measuring from the diff outdrive. Adapters for 1/8th scale and Mini-Z are available separately (not included). How to Use Connect Diff Analyzer to a power bank or any regular Micro 5V USB port. Connect the diff to the Diff Analyzer and press the power button. Diff Analyzer will show a numeric value for diff being tested. Test duration lasts around 3-5 seconds. Repeat the same procedure for other diffs to have numeric values to compare. NOTE: The viscosity of diff oil is sensitive to temperature. So ambient temperature variations can affect the measurement values. It is recommended to run the tests in similar temperature environments. About Us | View Store
