Rich,
I agree on your assessment on the use of the prop to control
rpm.............The ammeter is merely a tool to avoid
poping the IVO adjust motor elect breaker when reaching both the fine or
coarse pitch limit stops and with
enough use the pilot can learn to approx where the prop is pitched
to.............Several of our group flying behind
or ahead of the IVO use an ammeter for this purpose..............
Why in the world would IVO use a device that is designed to fail critical flight gear in the case of improper control
manipulation when they don't have to? Isn't this the classical and proper application for a polyfuse? Polyfuses are
used in power windows for this exact reason. You're kids can pull on that switch all day without damaging the window
motor. I'm thinking of the case where a switch gets shorted (like my belt sander's switch is right now...the power cord
is serving as a temp fix until I get time), or someone accidentally leans something against the switch.
