OK, so an RPM gauge isn't as sexy as an altimeter or ASI, but it's still important, and this is the best there is. The default scale is ideal for the majority of piston-engined aircraft from Cessnas to B17s, and has an adjustable redline so you can configure it correctly for your aircraft.

There is a different scale available for Rotax-type engines and yet more for turbines, although the Ng% RPM FIP Gauge might be more appropriate for those applications.

This is an engine RPM gauge, so it won't give you propeller RPM on a turbine aircraft like a C802. It does work perfectly well for piston aircraft with constant-speed props, as the engine RPM is directly related to the prop RPM.

The gauge has additional options for up to four needles, so one gauge can service four engines independently. That's some serious programming right there.

Add the percentage fuel gauges on the side and you've got a really useful gauge for any GA aircraft.
