Adhering Micafilm
=================

Roger,

I have been using Pliobond contact cement mixed 50-50 with MEK to apply
Micafilm. This will made the contact cement about as thick as clear dope.
Brush it on and let it dry at least 30 minutes, overnight is also OK. The
fibers in the Mica fail before the glue joint. One other tip when using
Micafilm is that everyone who has used it knows it is almost impossible to
patch less that a rib bay because it shrinks before it sticks. All you need
to do is apply the patch using clear dope around the open edges. Lay on the
Micafilm patch and let the dope dry. Then shrink as you normally do. The
heat does not effect the dope.

R/C DT
======

I think it is good that as many as possible express their opinions on
the subject of the use R/C for DT. Unfortunately, as is the case with
most controversial subjects, those in opposition are generally more
vocal. We are all quite aware that our FAI class models have become very
expensive, yet I hear relatively few seriously complaining about this.
But as we saw at the Max Men's contest last Sunday, quite a few in all 3
classes chose not to fly in that high wind Sunday morning rather than
risk damage to their models. I'm not suggesting that R/C DTs would have
helped in those winds. I'm just pointing out that we place high priority
on not putting our models up when there is a good possibility that they
will be damaged or lost.

The vast majority of flying sites are nowhere near as nice as Lost
Hills. Many are small, have trees, corn, lakes, and other hazards. I
would dearly love to be able to DT early---even missing the max---if I
see that my model is heading for trees or houses. The European flyers
will tell you that even with a beacon, they can fail to find their
models high up in a dense stand of trees. Now if I flew F1Cs or F1Js, I
would dearly love to be able to bring my model down quickly when I have
an over run, and what power flyer doesn't have an over run now and then?
How can anyone object to this use of R/C DTs?

My good Kiwi friend Dave Ackery implies that the introduction of R/C DTs
will be the technical and costly addition that kills off FAI FF models.
He claims the number of participants continues to decline. Dave should
come back here to California. Here the numbers are increasing at a good
rate. I was extremely pleased last weekend to see that we now have a
wonderful group of very capable juniors flying FAI models. The cost of
the R/C DT systems will not be nearly as high as the cost of a good
tracking system---which we are all quite willing to pay for. I doubt
that these DT systems will cost as much as the Russian winder I just
ordered from John Clapp!

So in summary, I am confident that a majority of us are going welcome
the approval of a rule change that will allow the use of R/C DT systems.

Polyspan and fuel limitation questions
======================================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.

In the Feb 22 newsletter David Ackerly asked about reasons for fuel
limitation in F1C. He correctly stated that such a limitation would
encourage use of fuel efficient engines...a diesel would probably run for 10
- 15 seconds on the same fuel volume as a hot glow engine. However, the
most vexing problem in F1C as it is now practiced may be the ability of the
timers to accurately gauge the engine run. A fuel limitation rule would
remove that problem...of course, the timer would have to be trained to
observe the that the competitor did, in fact, make the switch from the
starting and tuning fuel supply to the flight fuel supply.

As for Polyspan: Jorgen Korsgaard mentioned fuzzies on the surface after
covering. Most of the Polyspan that I have used has a smooth side and a
rough side. The smooth side reflects more light than the rough. If the
model was covered with the rough side out, then the fuzzy result that Jorgen
observed would be seen. A complicating factor that I have observed with
Polyspan is that abrasive action on a properly covered wing will result in
the fuzzies. For example, the location where I gripped the wing to remove
it from tight-fitting wing joiner wires became quite fuzzy as did the LE
where it rests against the bottom of my model box!

Congratulations on publishing the Maxmen results so quickly! And thanks to
George and all the support staff for running such a large contest so
smoothly. Since I can't name all the helpers, perhaps someone who can would
like to.
Chuck

[The Contest Management were George Batiuk and Bob White. The F1A Event
Director was Don Leath, Bob was the F1B Event Director. ... at the risk
of getting some static the F1C guys can't take direction... so there wasn't
one but Dukie supplied the fuel.
Judi Batiuk and Jean White helped with the pre-content preparation
as well as on the day. The scores were collected by Al and Judy Hotard,
Connie Piserchio and Mary Smith. Lindy Murrell did the score
keeping. Janna van Nest coordinated the on-the-field food. Brian and
Janna van Nest donated the Junior trophies. .. and I hope that I did
not forget anyone.]

RCDT
====

Hi Roger,

Some comments on RCDT issue:

As I have some experience in using RCDT, I would like to add some
comments:

RCDT after the model has maxed (extended flight):
In windy conditions, where it appears to be an advantage using RCDT, the
real advantage is not that big unless you are actually standing under
the model. In most cases however, the sportman is several 100's meters
away from the model and it is therefore difficult to fully assess the
situation downwind. In other words, watching the model from such a
distance gives a restricted (2-dimensional) view of the situation:

- Estimation of distance is too inaccurate to reliably avoid or overfly
obstructions

- Ground level obstructions (water, crops etc.) can usually not be seen
from the start line

- Elevated obstructions (buildings, trees, powerlines): the model can
hit such an obstruction anyway if it is flying low and the flight is
extended.

- In practice, RCDT has its most use in calm conditions, where you are
close to the model to avoid obstacles you can see (corn fields etc.) or
with someone downwind chasing the model on bike.

RCDT before official flight:
How can this be enforced? If someone has a receiver mounted, and sets
the timer to 2 min 50, how can he proof he didn't stop the flight using
RCDT, or how can the timekeeper proof he did?? Such a rule can never be
enforced!

RCDT 'jump to' function
One can give this function any name he likes, but this is definitely
radio control. If this is allowed, pandora's box is opened. With the
current state of the art in electronics, the possibilities are endless.

Therefore my conclusion: RCDT has possibilities, but of a far more
limited potential than most want to believe. RCDT before max-time and
jump-to functions should in my opinion not be allowed for the reasons
stated above. The only possibility left is RCDT after max-time, but this
has only limited advantages in calm conditions or when using a 'chaser'
mobile enough (motor bike) to stay under the model.

Best regards, Allard


Regaining use of Galeville, NY flying site
===========================================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.

Roger - I would like to get the help of all free-flighter in the US to
assist us in the re-acquisition of the Galeville NY flying site. Following
is a copy of a letter from Alan Abriss of the NY Skyscrapers explaining the
current situation. We are asking that free-flighters take 10 minutes of
their time to send this letter to their Congressman or Congresswoman.
Thanks. Tom Kerr

Fellow free flighters,

To help clear up some of the confusion about what to write to your
congressman concerning Galeville, the Skyscrapers have come up with the
following form letter. Please copy this letter and send it off to your local
Congressman. Just copy and paste the following. Thanks everybody.

Honorable (name of congressman/congresswoman)
House of Representatives (or local district office)
Washington, D.C. 2O515-322O (or local address)

Dear Congressman/Congresswoman

I am writing to seek your support in a matter of great concern to model
aviation enthusiasts throughout the northeastern U.S. After nearly three
decades of access to the Galeville airfield (near Newburgh, N.Y.)
aero-modelers were abruptly "evicted" when control of the field passed from
the military to the U.S. Fish and Wildlife Service.

The Galeville site lies within the congressional district represented by
Congressman Maurice Hinchey. With the help and encouragement of Congressman
Benjamin Gilman we are asking Congressman Hinchey to support our effort to
reinstate model airplane flying as a permitted activity at Galeville. We
already have the unanimous support of the local Shawangunk Township Board
and the Town Supervisor.

Congressman Gilman has a complete file of information, including
environ-mental impact studies, attesting to model aviation's benign effect
on what is now the Galeville wildlife site. He has shared this information
with Congressman Hinchey, who is reviewing it. Please discuss this matter
with Congressman Gilman and then speak to Congressman Hinchey on our behalf.

As a model airplane hobbyist, and as a constituent, I ask that you support
the effort to return model airplane flying to Galeville, and that you ask
Congressman Hinchey to do likewise. Thank you for your time and
consideration.

Respectfully,
