Banggood

the battery that was in the device was flat but you get an extra one in the packet. just need to unscrew the 4 screws and take off the bottom cover and replace the battery. the one button puts it on and the other one you can select from 2 to 9 blades to measure the rpm. good product banggood!

The order arrived fine, a bit of trouble with the tracking, but that's a package deal. Having a tachometer is a fundamental tool for any model aircraft that has nitro or gasser engines to better carbure the engines. I haven't tried it yet but I've already had other products of this brand and I've never had any problems. I recommend having one among the basic hobby tool

El pedido llegó bien, un poco de problemas con el rastreo pero eso es cosa de la paquete ría. Tener un tacómetro es una herramienta fundamental para cualquier aeromodelista que tenga motores nitro o gasser para carburar mejor los motores. Aún no lo pruebo pero ya he tenido otros productos de esta marca y nunca he tenido ningún problema. Recomiendo tener uno entre la herramienta básica del hobby

Love it! Tried with a 2 blade propeller on a white surface and it worked great. It didn’t worked on a black surface (probably because my propeller is also black), but that is not a problem.

Seems to work well. Select number of blades, then point at prop/rotor and take reading. Very easy and seems to be accurate. I dont care for the power button placement and battery location. It's very easy to accidentally press the power button, such as when it's in my toolbox. Must unscrew back plate to access battery (no separate battery compartment lid). Takes CR2032 button cell, which are expensive, so accidental power on and battery drain is a concern. I plan to 3D print a storage case

Excellent tachometer and very accurate. Make the test with a neon tube. Set the tachometer on "2 blades" and point it toward a single neon tube. It will indicate exactly 3000 RPM. The tube is fed with 220 V AC 50Hz. That means 3000 cycles per minute and that means 6000 lightnings per minutes (and 6000 switching off). The instrument is set on "2 blades", so it will indicate 6000/2 = 3000. And if you set it on "6 blades" it will indicate 1000 RPM. A very good tachometer indeed.
