Hey to all,

The tachs are being tested, but the weather is making it slow go. Syd has the 40,000 rpm version. He lives upthere where snow gets in the way. We are also going to have a heli model of the tach which reads the rotor blades accurately to 2000rpm. Most sport helis like the 1800 to 1850 rpm range. Mounted on the heli, one can read the rpm at hover at 10-12'. Also stores the highest rpm during the flight. Voltmeter when engine is not runing. The one we are testing on our show display, and on airplanes, are working perfect. On it goes.
