RC Tachometers for Model Engines

A tachometer reads the rpm of a spinning propeller, giving you a clear number to tune a glow or gas engine's needle settings and to compare how different props load the same motor. This category offers handheld digital tachometers suited to that job at the flight line or on the bench. It is a simple instrument that earns its place in a field box.

Digital Tachometers

The Flying Anderson Digital Smart Tachometer II and the Magnum Digital Mini Tach both read propeller rpm from the light passing between the blades, so there is no need to touch the running prop. A digital readout makes it easy to note peak rpm as you adjust the mixture.

Checking rpm takes the guesswork out of tuning and helps confirm an engine is reaching the numbers you expect for a given prop.
