At the risk of starting another disputatious thread about alternators, is
there any field experience with Plane-Power? They appear to have addressed
some of the concerns that have been expressed over the last months and they
are now selling into the experimental market. According to a spokesperson
their units have improved cooling fans, internal regulation with external
control via the field circuit, overvoltage protection mounted on the
alternator, balanced rotating parts, machined drive pulley, low voltage
warning light and all the parts needed to mount the system on a Lycoming
(for instance). Apparently the regulator is set to 14.3volts plus or minus.
I do not know who manufactures the basic unit. Does anyone out there know
these people or have operational experience with their equipment? They
apparently sell through distributors which include Aircraft Spruce and
Chief. Prices are not extremely low but are substantially lower than B&C's
60A with LR3. Comments please.

Thank you.

I have a very little experience with Plane-Power, both customer
service and flying.

I was one of the first to receive an experimental unit, right
after their certified models were certified. They were extremely
nice and sent me proto's of both the 60 and 70A so I could
see which one fits the RV-10. (The answer is both) The 70A
runs cooler due to a bigger pulley, so I bought it. Since this
was their first experience selling to that market, and there are
so many varieties of engine block styles, there was a small
issue originally. On my engine, there was a spot on the
block that interfered with their mounting swingarm. They were
extremely interested in making it perfect, so they got measurements
from me and literally had hundreds of arms made that would conform
to this engine block. I thought that was exceptional customer
service that they would make sure that the arms fit perfect with
no shimming or other cobble jobs to make them work...and it was
very nice to help improve a product for a bigger market.

Mine does have dual fans, and the front and back both pull towards
the inside, and it exhausts out the center. Mine also came with
a blast tube mount, which I did hook up. It has Overvoltage protection
and low voltage warning lights (they do work with 12V LED's too).

Yesterday I had my first flight and today I flew again in my RV-10.
The alternator charged just fine and everything worked great from
first glance. There's not enough experience yet from me to
give a ton of info, but I can tell you that I think my alternator
was putting out 13.8-13.9V.

All in all, I looked at it as a great savings, having the built-in
regulator, and knowing how hard they worked to get FAA/PMA approval
on their certified units, I felt reassured that they tested their
experimental OV protected units too. I hope I never have the
opportunity to test it first hand. In addition, they aren't just
rebuilt units, and they do use things like special brushes or
something like that that work at high altitudes.

I was happy enough with them that I plan to buy a future
standby or Aux alternator if they get one developed and
out to market. They are also just very nice people in general,
which is always worth a couple of points in my book.
