Perform precise and accurate motor data analysis with the SKYRC RC Car Motor Analyzer. This monitor provides you with all the information you need to perform adjustments to your RC car's electric motor. The tester features 3 settings to read out information. Power testing lets you read out the KV (RPM per volt), input voltage, RPM, and current drawn by your RC car's engine so you can make accurate changes to the power source and wiring. Motor timing shows you the physical endbell timing (tools are required for rotating the sensor board). The noise level tester lets you examine your motor for poor assembly or an unbalanced rotor, helping you solve minor imbalances before they become a problem. The kit includes the Motor Analyzer, 3 motor cables, 1 motor sensor cable, 1 DC input power cable with banana connector, 1 DC input power cable with Tamiya connector, and the instruction manual. Knowledge is power, and the SKYRC RC Car Motor Analyzer gives you the knowledge you need to excel on the track and keep your build well-tuned for years to come.
