A tachometer isn't strictly necessary for combat, but they're fun. We use them to measure the RPM of our engines. The best ones for our purposes are the TNC Tachs, from Skyborn Electronics. Here, mine is shown reading the RPM of my fluorescent light fixtures.

Of course, this sort only works with the plane sitting still on the ground. Another approach, pioneered by Stuart Sherlock, is to use a computer to listen to the plane as it flies around the circle and determine the RPM in flight as well as the speed of the plane. Be sure to check out his articles here and here.

And since control-line planes fly in a circle of (relatively) fixed radius, one can use an acoustic tachometer from the center of the circle and avoid interference from Doppler effects.
