Product overview
The SkyRC Helicopter Optical Tachometer SK-500010 measures rotational speed on helicopters, propeller-driven fixed-wing airplanes and multi-copters. Its 3D Glass Screen provides an optical measurement method: when rotating blades appear stationary through the screen, the flashing frequency shown on the LCD corresponds to their RPM. The instrument covers 700-4500RPM with an accuracy of ±1RPM. A rotary dial adjusts the RPM value, while the LCD presents the reading.
Five saved RPM presets provide quick access to settings for different helicopters and airplanes through the F key. The unit also saves the last RPM value before shutdown as a preset. Ten aperture levels, adjusted with the F key, accommodate bright or dark backlighting when viewing the rotating object through the screen. The compact, ergonomically designed tachometer weighs 45g and uses a CR2032 button battery for power.
