Even if the amplitude of the square wave from the Rotec tachometer is less than
12 volts, someone on this list can design a simple transistor amplifier that
will boost the voltage above the minimum required for the Dynon D-180 tachometer
input.

This question is for Bob-
In the news today it is being reported that a passenger hacked in to
the planes flight controls and made changes, using the entertainment
system network. Do you feel this is possible?
Anyone else have input on this?

stethoscope (cheap rod in ear type). Compare it with noise from the upper bearing.
Afterward, occasionally listen for increased noise (growling or clicking)
at the lower bearing.

which is designed to better accept both radial and thrust loads. Fafnir 7000
series comes to mind. Any good bearing supply house should be able to help.
Remember that angular contact bearings are directional and are designed for
thrust load in one direction only. If you view the bearing, one side will have
less spacing between races; that is the side which will accept increased thrust
loads.
