Subject: | [Please Read] - Last Official Day of List Fund Raiser! |
Dear Listers,
Its November 30th and that always means a couple of things. Its my birthday again;
number 49 actually! But it also means that its that last official day of
the Matronics Email List Fund Raiser! If you been thinking about picking up
one of those really nice incentive gifts now is the time to jump on it!!
If you've been meaning to make a Contribution this month but have been putting
it off for some reason, NOW is the time!
I will be posting the List of Contributors in a few days, so you'll probably want
to be known as a person that supported the Lists!
I want to thank everyone that has so generously made a Contribution this year in
support of our Lists. It is your generosity that keeps this operation running
and I don't ever forget it.
The List Contribution Web Site is fast and easy. Please support our habit by making
your Contribution right now:

Or, by dropping a personal check in the mail to:
Matt Dralle / Matronics

Thank you to all in advance!

Subject: | Spins in an RV-6 |
I agree with Stein that each RV-6 is different. I've only spun mine,
but it seems to spin different than other -6 owners I've talked to
that have spun their birds.
My -6 is reluctant to spin and requires full pro spin controls to
enter and/or to stay in a spin. That includes spins in either
direction, accelerated entries, slow, nose up entries, entries with
and without power, and entries with various CGs. All seem to result in
similar spin conditions with relatively slow smooth entries and very
quick recoveries using only neutral controls. The rotational rate of
my -6 spins is quite low though I have not timed them. The only
disconcerting aspect is vertical oscillations while in the spin - the
nose tends to vary 30=B0 - 40=B0 up and down with a very rapid
transition
from nose high to nose low and with two or three vertical oscillations
per turn. I've only held the spins for two turns as the vertical
oscillations are disconcerting and seem to increase in violence as the
spin progresses. Two turn spins and recovery to level flight usually
takes less than 1,000 feet of altitude with less than three Gs during
the recovery. In fact, if the recovery is initiated with the nose
going up, the spin stops with virtually no additional loss of
altitude. I have not tried inverted spins and don't intend to.
My spin experience is limited in light airplanes with only a few spins
in various birds. However, I have extensive spin experience in the
T-37, with literally thousands of fully developed spins to include
accelerated and inverted spins. The T-37 had a very stable spin, about
30=B0 nose low, a very rapid loss of altitude, and a very high rate of
rotation (a full rotation every three seconds in its slowest, most
stable mode.) Its recovery required aggressive full anti spin controls
resulting in a near vertical attitude following recovery. By
comparison, my -6 spins MUCH slower, with a much quicker and much
smoother recovery, but with the vertical oscillations mentioned above
if held in the spin.
I encourage RV owners to familiarize themselves with their bird's spin
entries and recovery. The emphasis should be on spin prevention, with
no intention to fully develop a spin or hold the spin for more than a
half turn. Those individuals with no previous spin experience should
get some qualified spin instruction before trying it solo in any
aircraft. Spins should be respected, but not feared.

Guys, (and gals...), those three notes on spinning are three of the best written,
concise, and non-hackle-raising notes I've seen in these fora. Kudos.

Does anyone in the So. Cal. area know of or have a jig to build the -6 Fuse
lage? I'M just about at the point where I'll need one. Thanks.
