An AMA Gold Leader Club

No. 428
FROM THE PREZ
by Bob Sudermann
The amount and wide variety of expertise that exists
within the membership
of this club always amazes me. It ranges from cutting
foam core wings, to
scratch built mechanical devices, to laser cutting techniques.
We have
experts in four-cycle engines, gas powered engines,
electronics, and scratch
building; I could continue this list with just about
any area relating to
model aircraft. The two most recent examples were presented
in the January
general meeting. First Rob Caso explained the requirements
and techniques
required to lay out the parts, use a CAD (computer aided
design) program to
get the designs into the computer, and cut the parts
utilizing a laser.
There is a lot more to it than these three steps, and
Rob did a great job
explaining it. If you missed the meeting, check out
his article in the
January Hear Ye! Thanks again, Rob, for your time and
effort in sharing your
unique talents.
During the Show and Tell portion of the meeting, Russ
O'Brien presented yet
another mechanical marvel. He is building a 'Single
Engine - Twin Prop'
aircraft. He has designed and is building a belt drive
system which utilizes
a single four-stroke engine that drives two props turning
in opposite
directions. This will help counteract the 'P Factor'
effect of the single
prop, which tends to turn a tail dragger to the left.
The system has not
been tested yet, but you can expect to see it soon.
The normal BOG meeting for February 4th will be replaced
with a Flight
Instructors' meeting. I would like to discuss the use
of a Flight Manual,
which includes a Flight Log and a Formal Sign Off by
the Chief Flight
Instructor. A separate letter has been issued with a
few more details, and I
hope all current instructors can make time to attend.
What's everyone working on? Let's bring out any completed
or partially
completed winter projects to the March meeting on the
11th so we can all get
a look. This may help motivate some of us to get something
started or
completed. Remember the flying season is coming fast!
See you at the field.

VFSS BOG MEETING
by Steve Kolet, Secretary
January 7, 2003
Eighteen members present
Meeting opened at 7:05 PM by President Bob Sudermann.
OLD BUSINESS: None
NEW BUSINESS:
Item 1: 2003 Budget Review
a. Minor increase in Field Marshall allowance for hats.
b. Minor increase in sunshine fund.
c. Small increase in banquet line to allow for third
entrée selection.
d. Discussion concerning possible budget/cost reductions
in out years by
reducing mailed newsletters. Research required to determine
effect of
reducing mailings, printing costs, availability of online
newsletter, etc.
e. Education line was increased to $300 for two school
programs
f. Motion to approve budget was made, seconded and approved.
Item 2: The trip to the WRAM's Show was discussed by
Joe Weiser. Currently
have 3 personnel who have paid reservations and 7 others
who have indicated
interest. Joe needs 40 paid to make the trip. Decision
was made to send mass
email for interest ASAP. Money must be in Joe's hands
by Jan 20th or trip
will be canceled. (Trip expense is $1500 for bus, meals,
admission, etc.
Cost is $40 per person. There is a $200 refundable deposit
if cancelled by
January 21.)
Item 3: Al Primas is in Montgomery Hospital and has
been hospitalized with
appendicitis since mid December. Sunshine fund sent
flowers.
Item 4: Discussion about noise at the field and sound
testing for the next
year was heard. Decision was made to test aircraft on
an as needed basis. A
rig to hold the sound meter at a two foot height to
eliminate interference
by a person holding the meter will be made. Adherence
to the flying field
boundaries was emphasized! Noise control and Field Management
guide was
passed out for reference.
Item 5: Bob Suderman passed out sample instruction
packet for student pilot
instruction from ground school through solo and transition
to advanced
performance aircraft.
All business was concluded. Meeting was adjourned at 8:15 PM.

DO MODEL AIRPLANES TALK?
By David Beach
We all become accustomed to listening to model aircraft.
Typically we focus
on the most audible component, the engine. Is the engine
running well and
fuel mix okay? We listen for the right sounds in reaction
to throttle up
from idle. We listen to make sure the engine doesn't
sag in response to the
pinch test or holding the nose up. These are the obvious
ways in which our
flying models "talk" to us and indicate their
airworthiness.
But model aircraft can tell you a lot more about their
condition if you pay
close attention. At the field the other day, I overheard
a pilot say, "It
sounds like my fuel tank is foaming." In that case
the airplane was
attempting to say, "You did not set your timer
and I'm about to run out of
fuel." A minute or so later the airplane ran out
of fuel and a successful
dead-stick landing was the result. With a little more
pilot awareness, a
powered landing would have been possible.
Unusual noises are often a precursor to something that
is about to go wrong.
Paying attention to what your airplane is telling you
can mean the
difference between landing with a loose muffler and
losing a muffler in the
woods. It can mean the difference between slowing down
an airplane
experiencing control surface flutter and having control
failure. Unusual
model aircraft noises have a variety of sources, but
your first reaction to
an unusual noise should probably be slowdown, land,
and inspect.
I have an airplane that gives feedback that is not audible,
but it's talking
to me nonetheless. With a fuel tank that's well ahead
of the center of
gravity (CG), once the fuel level starts to get low,
this airplane gradually
gets light in the nose and starts to climb from what
started out as level
flight trim. I don't need to look at a timer or listen
for changes in engine
noise to know that it's about time to land.
Have you ever attempted to fly with your antenna down
or a low receiver
battery? It's not uncommon to get a short "glitch"
and have temporary loss
of control before all is lost. If you recognize that
your airplane is
attempting to tell you something, it can make all the
difference.
Learning to pay attention to what your airplane is trying
to tell you is not
always easy. Through personal experience I've learned
a new signal to look
for that might have saved two different airplanes, and
I'd like to share it
with you.
Any sudden change in flight trim means something is
wrong!
Twice in the past year, I have retrimmed airplanes in
flight and kept flying
when I might have had the opportunity to avoid an in
flight failure. Just
because adding three clicks of down-trim makes the airplane
fly straight and
level again doesn't mean you should keep flying; it
means land now if you
can.
Is a control horn coming loose? Has a control rod bend
become fatigued and
gotten soft? Has the engine mount shifted and changed
the thrust line? Has
the battery moved in the fuselage and changed the CG?
Has a wing bolt mount
failed and changed the trim? When an unusual change
to flight
characteristics occur, it is our job as pilots to understand
why and
properly assess the impact of that change. Get this
done safely on the
ground.
Staying in touch with what your aircraft is trying to
tell can make a big
difference. It can make the hobby more rewarding, and
can make you a safer
pilot. Do model airplanes talk? Only if you pay attention
and listen very
closely.
