| Subject: | Yak n CJ Aircraft anniversaries and Oshkosh... |
Folks,
I'm sitting here with my copy of a newsletter dated Winter 1993 Vol 1, No 1.
and titled "The CJ-6/Yak-18 Driver"
In that first edition, page 1, the editor Bud Harrell asked this question:
"...Will there be a Yak association like the T-34 association? I cannot answer
that question. For now, we may be too few, and too far flung..."
He reffered to the CJ-6 as a Yak-18 in those days and had some 23 pilots respond
to this proposal to organize, out of a distribution list of 47 owners.
For many of you, the founding of the Yak Pilots Club and evolution to the RedStar
Pilots Association, has been a positive addition to your interest in these
aircraft and this great past time. The RPA (RedStar) is a unified all-aircraft
aviators association, it was about the pilots flying, and not about one type
specific aircraft or another - the name change proposal itself was done to
cement that concept not long after a Yak 52 pilot called up before coming to a
California fly-in we were forming in 2001 and said "This ain't one of those *$#@
CJ club get togethers they just refer to as 'Yak' is it?". No, this is RedStar...and
we made it a goal to forever remove such an incorrect perception among
aircraft owners of Eastern Block aircraft (and beyond, RPA membership is
open to pilot-owners who simply commit to the goals of training and fun).
I've heard that the Yak 52 is 30 years old this year? The CJ is 50 or maybe
more. Whats really important, as is being pointed out by Condor [pres] to the
volunteers and seen through the agressive refocus of Oshkosh 2008, as you will
read in this quarters Red Alert, is the realization that the RPA is 15 years
old - and this event is a National RedStar Celebration of the ENTIRE associations
membership and it's collective accomplishments and evolution.
RPA ops at Oshkosh may highlight the CJ and Yak anniversaries in specialty publications,
mass formations and other venues, but this event is getting a lot
of planning effort (and RPA treasury and sponsor money) to support the pilots
and members equally, doesn't matter what you fly or drive.
And yes Bud, the community did indeed grow their association...from 23 in 1993
to well over 450 today.
Food for thought,
Drew

It is done. The module is available from Bob Nuckolls of the
AeroElectric Connection. Tom Elliot has the prototoype installed in
his CJ. Contact Bob at http://www.aeroelectric.com
The one thing I didn't do is sit down and do a set of detailed
instructions for installing it. I didn't have a CJ to work on and,
frankly, it became something I just didn't want to spend any more time
on as any CJ or Yak I own will lose its generator to be replaced by an
alternator whose field circuit will be automatically disabled during
an OV event.

Yup.

Gang:
Can Brian or someone enlighten me on this topic. From what I recall, both gen
and alt systems can have an overvoltage situation. The external regulator is
supposed to control this. From what I gather, the CJ/Yak electrical system does
not provide protection for this?
Please enlighten me!

That is correct.
> The external regulator is supposed to control this.
No, not necessarily unless the regulator specifically has OV
protection. Most standard regulators do not. Spam-can electrical
systems typically have a separate OV protection relay that sits
between the regulator and the field circuit of the alternator. If the
voltage goes too high the OV relay disconnects the field circuit thus
shutting off the alternator.

I believe that the Yak has an OV relay but the CJ does not. I got Bob
Nuckolls to cook up an OV protection circuit for the CJ that will pop
the field circuit breaker and turn on an OV warning light. Its
installation is relatively simple. It must be wired to the main
electrical bus to sense the voltage and it must be wired to the field
circuit between the existing regulator and the generators field
winding. If there is an OV event, it disconnects the field circuit
thus protecting the rest of the electrical system.

Does this help?
