<blockquote type=cite class=cite cite><font face="arial" size=2>Any
"aircraft" alternator will not have an internal regulator, but
just about every "automobile" alternator will incorporate a
regulator. </font></blockquote><br>
It is historical issue. Many years ago, when man start to fly, all the
best was in <br>
aircraft industries and at some moment development was frozen due to
different<br>
regulations and limitations. But automotive industries went further using
much<br>
more advanced technologies at this days. <br>
Speaking about incorporated regulator, it is also regulations, which do
not have<br>
solid ground to stay... Look, in aircraft you have much more
cooling then in auto.<br>
Yes, more vibrations on the engine, so when you will use solid state
regulators, <br>
it is really do not much matter. Old type regulators has all
through-hole" components <br>
so, it is more weight per given volume. Modern components is surface
mount <br>
and much less on weight, so less force to tear them out...<br><br>
<blockquote type=cite class=cite cite><font face="arial" size=2> I'm
going with the B&C alternators myself, which are nothing more than
Nippon Denso auto alternators which have been precision balanced and had
the built-in regulator removed. </font></blockquote><br>
Balance is almost no matter in such small weight since you have much more
<br>
disbalanced crankshaft with huge masses of pistons and push rods flying
back and forth.<br>
Another "cake" to move to the Rotary Engine! No flying masses
anymore...<br>
No vibrations... Think about...<br><br>
<blockquote type=cite class=cite cite><font face="arial" size=2>Yes, it's
a lot of money, but it's hard to argue with their record of
success!</font></blockquote><br>
Now, speaking about money... Go to junk yard and buy any Japanese
tinny altranator<br>
for 80..100 A for $10 or buy directly from auto part store same for
$40. It will work<br>
same good. <br>
Most Jap alternators working for 150000 mi (~2000 hours) without any
replacement <br>
or even lubrication. Brushes almost new when you pull them for inspection
after<br>
100000 mi. <br>
At same time, I spend a lot of money to work around my 60' Chrysler
alternator on<br>
Cherokee. It is peace of junk to compare with modern Jap altrnator. But I
must to have<br>
that junk since it is certify flyer.<br><br>
