Starting from our anxiety and need for a speed checker to play mini4wd, we innovated to make a speed checker with compact dimensions but high accuracy when compared to the original tamiya mini4wd speed checker. We have done a comparison and calibration with a speed checker. More than 99% accurate with the original tamiya speed checker reading results. The speed checker can be used to set the speed of the 4WD mini before you put it on the track, this makes each of your runs more accurate and fun to avoid the 4WD mini car exceeding the setting limits that have been found. 2Fast Lab Speed Checker Version 2 [Lithium Battery Update] User Interface/Display: -Real-time rpm sensor reading -Realtime Speed reading/kph -Display Max speed automate refresh Specs: -Fast and Accurate Micro controller Program - Clear User Interface -High quality 3D Print Case with PLA+ -Precision sensor -Lithium Battery embedded -Type-C charging port - Dimension: 27mm (width) x 21mm (depth) x 85mm (tall)
