AmCup Correction
================

----------------------------------------------------------------------
For SEN,
The last two 2003 AmCup results had an error. I had Bob Biedron's scores =
split onto two separate lines. This has been corrected and Bob has the =
F1B lead over Dick Wood, 92 to 87 points. They should both watch the =
next two guys, Rich Rohrke with two 30 point scores and Greg Simon with =
scores of 26 and 29.
I'll put out this correction along with the Huron Cup and Nats results =
when I return from Muncie.
Thermals,

MMM FAI Annual Results
=======================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
24th Magnificent Mountain Men (MMM) FAI Annual (America's Cup) Contest
Twenty seven flyers from nine states (including Alaska) and Canada congregated
at our field to compete in the "toughest FAI contest in America." In addition to
the FAI events, we flew P-30, Gollywock, Open Power and had a HLG/CLG shootout.
The most notable performance was Ralph Cooney's victories in both F1B and F1G.
F1G went to a three-way flyoff which Ralph won by two seconds. A young junior
from New Mexico, Pat Cadieux, flying in his first contest, won F1H beating two
veteran flyers.
Apart from some breezy conditions late Sunday, the weather was absolutely
beautiful and thermals strong. We had several extremely long 30+ minute flights
(after DT) but no models were lost. The furthest was Don DeLoach's Nordic which
suffered a DT failure (dirt in the mechanical timer). 30 minutes in the air
took the model 4.8 miles from the launch site. To give you an idea the size of
our flying site, the model was still within the confines of the field.
Don
rented an airplane, reacquired the signal from the air and located the model.
Following the flying on Saturday, the "Lee Hines HLG/CLG Shootout Challenge" was
flown. It came down to Lee Hines with a Stan Buddenbohm design winning for the
second year in a row.
Saturday night also saw an enjoyable and well attended banquet at a local
restaurant. In addition to the storytelling and visiting, we took a solemn
moment to raise our glasses to the memory of Bill Etherington and Bill Gibbons.
Although Bill Gibbons is still with us in body, he will never be able to return
to the joy of Free Flight. The contest was dedicated to Bill Etherington.
After the end of the contest, we were treated to a display of F1E
(magnet-steered glider) flying by Bob Sifleet and Peter Brocks. They, along
with Jon Davis (also at this contest), form the first official US F1E team.
They will be flying in the F1E World Championships in Romania this September.
If this wasn't the biggest contest in this event's history, it had to be close.
Twenty-seven flyers made 40 event entries and flew 288 official flights. We'd
like to thank all who helped with the contest. I'd especially like to thank
co-CD Bill Lovins for helping to run and prepare for the contest.

Northward with F1Es
====================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
The day following the great MMM 12 rounder I had a chance to watch Bob
Sifleet and Peter Brocks test out their magnet guided gliding missiles over
beautiful Death Valley just to the North of the (what the...) Sam Hill
flying site.
I didn't know what to expect but it turned out to be a real treat watching
the light floaters feeling their way down the broad, wildflower speckled
gully. It was eerie seeing them gently correct their course in little
increments. There were some beautiful flights that DTed after many minutes
of riding high in the slope currents...and what was a wonderment to me was
that there was very little discernable wind at that. Most impressive.
Note: The area is called Death Valley because if ships don't have enough
altitude before a south wind carries them over the lip it is a real struggle
to make a max. With the wind coming from the North --obliging the slope
gliders -- the name should be, Big Boomer Valley!
Hans Gremmer did good!
Billious G.
Guys, was a very impressive show and I wish "our" F1E team great success in
Romania this coming World Champs.
Down with T-tails
=================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
I've used T-tails numerous times with different twists on each attempt,
Nothing good ever came from using them. I believe that I was overly
influenced by enthusiastic descriptions of Karl Heinz Reike's hot power ship
at a World Champs. Anyway, I did get a lot of lessons on how an itsy bitsy
stab can lever its light weight into a very destructive force when the plane
stops suddenly.... that is, tail booms snapped in two pieces a short ways
ahead of the T-tail.
The best of those that I played with had the wing mounted above the
T-tail, and generally had a large amount of the fin below the fuselage.
One indirect but powerful argument against the T-tail was made by Raul
Hoffman in his compendium of aeronautical facts, Model Aerodynamics Made
Painless. Raul claimed that stability of a power ship was enhanced when the
axis of the mean moment of inertia was slanted up at an angle from the rear
to the front. According to him one of the most overlooked attributes of a
pylon ship was having the wing weight up high to achieve this condition.
Naturally, having a stab hoisted up in the air at the rear end subtracted
from this since it raised the rearward c.g. component.
To make this very short: The reason that this slant of the axis is helpful
is that when the ship was laterally displaced from its flight path it
assumedly rotates around the axis of the mean moment of inertia. If the
slope is correct the thrust line and wing would be angulated in a manner
that would help the ship return to its original flight path. (in
displacement the wing goes to zero lift angle while the effective downthurst
of the engine is increased by the resulting angulation; that combination
quickly pulls the ship back in line... if the slope is opposite to this, the
thrustline and lift of the wing only serve to feedback into the
displacement) If this is confusing just draw out a simple profile shape and
try rotating it using different sloping axis. It was an eye-opener to me.

Re: Model Rocketry Sites and Free Flight
========================================

I read with interest the suggestion that model rocket groups and FF clubs
might share sites. I think it's a good idea; but like all good ideas,
there's a possible glitch.
Last summer the SCIFs Old Time Free Flight had a contest on Lucerne Dry Lake.
Lucerne Dry Lake is a little better than three miles long and
about two miles wide. A well organized Southern California Model Rocketry
Association was also running a contest on the lakebed at the same time.
I will
say that the rocket CD got VERY uptight about free flight models drifting
over his flight line. We moved our contest site further away to minimize his
concern. As he pointed out, he and his association had purchased
some expensive liability insurance for their contest, and apparently one
of the conditions of insurance cover was that the contest be in an area
where there were no aircraft of any sort overhead at less than 5,000 feet
or so above ground level.
He had a legitimate concern, but he obviously had never attended charm school
of any sort.
So I'd say yes--rocketry and FF clubs can share the same sites--they just
shouldn't both be on the site at the same time. I'd also report that
later that weekend, we were about a mile away from the rocket launch
line--and an errant missile landed less than 100 yards from our
flight line. The missile was a rocket with a 4" diameter fuselage.
Who needs to worry about "incoming" at a
FF contest? Or the possibility of really getting "shot down" by a rocket
passing through your plane's wing? Better not to mix the two disciplines
on the same field.

Fat Cat inflation

My Honda Fat Cat tire pressure gauge goes from 2 lbs to 7lbs. So I think the
5 lb figure is real good. Can't find the repair manual right now, but it in
the house somewhere. Great machine though.

Just got back Sunday afternoon from Lost Hills and Tyler is ready to pack
his F1A's up for the Nats. We want to thank the members of the Scat Club for
their help and support in getting together his F1A fleet. Thanks to Brian &
Janna Van Nest, Bob Van Nest, Jim Parker, Pierre B., Don Zink, Black Magic
Timers-Roger M, Lee Hines, Dave Rounsaville, you have all played an
important role in supporting a new Jr. F1A flyer.
Off to the Nats!
Thanks again everyone Tyler & Randy Secor
