KitPlanes had a couple of interesting tidbits this month.
First on page 6 Mr. Hensley claims a Honda engine has a BSFC 29%
less than an aircraft engine so that would put it in the
the .28 BSFC category. Is he in for a rude surprise or what?
Assuming of course he can get that four place airplane in
the air and back on the ground with two Honda VTEC engines
and without killing Dave Morss.
The other item is Jim Weirr comes a cropper on page 47 with
analog technology when it comes to an electronic engine monitor.
Pssst! Hey Jim, replace the silly mechanical rotary selector switch
with a digitally controlled analog multiplexer, 10 or 12 bit A to D converter
and use a PIC single chip computer and LCD to linearize(s) the
recalcitrant sensor's reverse voltages and resistance's with look up tables.
Join the 20th century if not the 21st century. :-)>
