Beacuse of what can loosely be described as operational issues on the part of my service provider over 300 of these were bounced by him. There is no easy way of just sending those that did not get sent so this has been re-sent unchnaged.

The contest began at 1 pm on Friday, May 23 with the mini-events to give contestants a chance to travel and perhaps do some last minute trimming. The day had an overcast sky with light rain for most of the contest, but the winds were light and variable with most drift towards the west, but some rounds had essentially zero wind. One F1G flight DTd at over 6 minutes and landed less than one hundred yards from the launch pole. Jean Pailet had a massive overrun in the second round, and the model was just off the field in a tree about 30 ft up.

For the major events on Saturday, May 24 the weather was sunny with a persistent NE breeze of 5 to 12 mph. Because some of the models were approaching the edge of the International Aeromodeling Center field where trees are located on 3-minute flights, the max was reduced to 120 for the last five rounds. Even with the 2-minute max, strong thermals would take the models close to the western edge of the field on some flights. Others in strong thermals landed after a total of more than three minutes in the air less than 300 yards from the flight line. The F1B fly-off between Paul Crowley and John Shailor was held at about 8 pm with no retrieval problems. The F1C fly-off is scheduled for the weekend of the Intercities contest in June at Muncie.

Looking for Gene Drake.

I have finally located an old Sympo that Gene Drake requested some months back, but I have misplaced his email address. Any help would be appreciated.

Hotels for Skyscrapers

Dear Free Flighters,

For those coming to the Skyscraper Challenge, I repeat the event schedule at the end of the message below, after the list of hotel phone numbers and locations. For directions to the field check www.brooklynskyscrapers.org

I did a little checking of the Middletown, NY hotels for this weekend.
The Days Inn and the Howard Johnsons are full. As of now the Middletown Hotel has some available (their non-smoking rooms are fine) at $75 plus tax. Also the Super 8 has a few left (a non-smooking double with AAA discount is $90, but mostly they now have single rooms left).

The Microtel has rooms, but they have jacked the prices way up for the West Point graduation (which, like us, decided to be a week after Memorial weekend this year). The Courtyard Marriot and the Hampton Inn likewise have set their prices exhorbitantly high this weekend. Lower than those is the Holiday Inn is at $134 with AAA. The Chateau Hathorn in Warwick is full Saturday night.

So if you don't find a local Middletown room, per the suggestion of the Super 8 or the Middletown Hotel, my suggestion is to use the hotels at exit 1 (Port Jervis) for those coming from the south, or at exits 5 or 6 off I-84 for those coming from New England (see the list below). There are also cheap hotels an exit further to the west off highway 17.

_____________________________________________________________
CAMPING ON FIELD IS ALSO ENCOURAGED
Tents on soft grass, or sleep in one of the two sheds, or
camp in the vehicle of your choice. [Watch for rain friday night.
Saturday night should be dry.]

Electric power

From: Vin Morgan

Now that electric power is everywhere in model aircraft it is time that the

original form, that is free flight, got with it. And electric power has some

nice aspects - no noise, no mess.. The trouble is, in a relatively short

time, electric power has got rather too good for free flight competition and

it seems difficult to find practical ways of limiting performance. The idea

of taking a leaf from the F1B book and limiting battery weight is not a

sensible option because battery technology is changing rapidly so a given

battery weight does not lead to a standard amount of energy.

Similarly, limiting motor run times is difficult and impossible to police.

But there is a way to regulate energy which is easy to control, safe, and

gives interest by providing flyers with many options. This way is to have

the electric power supplied by one or more ultra-capacitors. These recently

developed capacitors store orders of magnitude more energy for a given size

than conventional capacitors and (large ones) are being considered as energy

sources for industry and transport. At model size, a readily available

ultra-capacitor of 120Farads at 2.5 volts that weighs 29 gm stores 375 J

(watt second) of energy. A 30 gram rubber motor (4000 ft lb/lb rubber) holds

360 J (I should note here that this was pointed out to me by Sean O'Connor

and started my thinking).

Ultra-capacitors have a lot of advantages over batteries. They work from -40

to +65 degrees C, lifetime is ~10 years or 500,000 charge/discharge cycles.

Max discharge current 730A. And they can be completely discharged and

rapidly charged.

For contests, measuring the size of the fuel tank is simple - you just clip

on an inexpensive capacitance meter.

Motors can be chosen to give either a long slow run or a powerful short run.

In either case the energy will be the same. No motor timer is required - the

motor simply runs until the capacitor is discharged. In the simplest models

a brush type motor would simply be connected across the capacitor and power

would decrease throughout the run (just like a rubber motor - free flighters

can trim for that). It would also be possible to use an electronic inverter

to maintain voltage (or power) at the motor and to use some of the readily

available electronics to drive a brushless motor. The 2.5 volt limit of one

capacitor is probably difficult in terms of available motors and

electronics, so for practical flying a connecting 3 or perhaps 4 smaller

capacitors in series would give the same energy in a more usable form.

There are many possibilities which would make for interesting competitions

and development.
