Roger;

I tried the E-mail address you gave me but I haven't been able to contact
Gerhard Aringer yet.

Could you put a short note in the SCAT E-Mail list asking if someone has a
current FAX number or E-Mail Address for him.

Thanks
Matt Gewain



Rubber Rumours
==============

One always wonders how fast rumors and news travels
Well I guess the news that the May 99 rubber was good
travelled so fast that FAI have sold out of
1/8.  John Clapp says do not worry
if they told you you were on this list. It will take them
a little while to get all orders shipped.

I assume that another batch is on order ?

Another approach aka Letter from Leath
======================================
Palmdale, ca

Fellow sportsmen,
From what I have been reading and hearing ,  we FAI -  F1a ,b, c   flyers
Have some real and/or perceived problems within our niche of modeling.
	They are as follows:
	1. Performance beyond all expectations,
	2. Dwindling flying sites.  Nearly all flying sites in the USA are 
	    marginal at best for 2 minute maxes  let alone 3 minute maxes. 
	    only lost hills, Palm Bay, and Muncie are really good but if the 
  wind is in the wrong direction or is blowing a little  Muncie  is out 
	    and Palm Bay can be a problem.
3. Possible ear damage from F1C engines.
	4. Resistance to change.  None of us want to throw away perfectly  good models because it takes a 
huge investment in time and money to get them built, rigged, 
trimmed, and tweaked, not to mention  cost in $.
Since "change for the sake of change"  is almost always a bad idea, we need to make sure that our reasons 
for change are real and not perceived, hence this web forum.
Some of my thoughts on the problems:
The criteria are:  
	a. None of the 3 events should be capable of exceeding 3 minutes in  "dead air"
	b. None of the current models should have to be discarded.  "time"
	c. A minimum of modifications should be required.  "money" &"time"

A possible solution which would meet the criteria:

	Load the models with ballast , however much it might take.
This solution runs against the grain of everything FF stands for.
	However, it would solve the problem if done properly,
             and just think of the new challenges!!!! 
Some research (trial, error, and record) would be needed to 	determine how much ballast would be 
required for each class.
	Would need early morning and late evening bench mark  data
	base established for before and then after the weight is added
	to determine the amount of weight necessary to meet criteria 
	"a." Above.
Would we enjoy making our FF 's into lead sleds ?????   I don't think so!!!

There are some other thoughts :  f1c= change rules to say "max swept 
Volume = .060ci.  Would cost money =bad.  Would allow longer engine 
Runs hence more accurate timing=good.  Would set up new challenges
For engine developments and airframe improvements = good.
F1B = could allow a double type of model i.e. Could allow "old"style 	
Wakes (no automation-folding props and dt's  only  with 40 grams of 
Rubber and air frame weight per 1990) to fly competitively against
The so called "high tech " fib's.  This would probably bring back some old
Timers and some new modelers (RPW?).
F1A = same as F1B ie.  High tech vs "old" style  = 410gms with circle tow and
Dt only.  Note: no restrictions on building materials in any class.

 
   	thermals,
	Don Leath

[Don .. one comment , and not just to you. ..
Don sent me his note in a Microsoft Word attachment all in upper case.

I not like publishing items that are all in upper case so I
ran it thru Word's conversion to 'Sentence case' , beceause
Don's  concept of sentence did not coincide with that of Bill Gates
the display might be a little strange.

Authors, just keep it in  mind that this does out
in plain text, so if you have some particular format
that you desire to express your ideas you need to figure
out the best way to sent it to me.]

Hi Roger,

I've been reading the SCAT EN for the last few weeks and all the =
discussion of rules etc. has led me to throw out my thoughts as well.

F1C Performance- the most obvious and easiest first step to reducing F1C =
performance is to require fixed blade props. I don't remember who =
suggested it, but he was right on. Fixed props are much, much less =
expensive and would solve the quandry over the geared engine. I don't =
think any one would want a 12" prop hanging out in the breeze.

F1C Fuel- I would like to see the  fuel rule rewritten to eliminate the =
requirement to use castor oil. Castor is icky gooy stuff and it eats up =
rubber. I don't know of any performance advantage to synthetic oil so I =
don't see the basis for the rule as currently written.

F1J- The engine run and max flight duration for F1J are ridiculous. On a =
7 second engine run you can nearly DT at the top and still get a max. I =
would like to see the rules rewritten to match F1C, 5 sec and 3 minutes. =
Models designed for this event are clearly capable of this performance.

Regards Bob
