US Comments on FAI rules changes
================================
George Xenakis says that US flyer's comments to
the AMA and hence the FAI are being channelled through
Dan Tracy.
Dan, how do you want people to get those comments to you ?
We will try and publish a summary of the proposed changes
to help people focus their opinions
FAI Web Site
============
The FAI have revamped their web site at www.fai.org and
it looks good.
They have used a new technology for managing the information,
in particular the contest calandar. It is important for contest
orgaizers to look at this before submitting their information
each year. They now include e-mail and web site addresses.
Electronic timer souces of information
======================================
Ceeny Breeman has written a very intersting article on his web site
http://ping4.ping.be/cenny_breeman/BI/electronic_timers.html
about electronic timers. He talks about different mechanical linkages
which appears to be a major problem for some flyers.
Words from an Old Codger
========================
I got a call from Bob White the other day. He said
that he was an Old Codger and didn't have a computer
but got to read SCAT Electronic news anyway.
He wanted to make a a couple of comments on the
F1B rules changes - Firstly if you must changes
- do not reduce the rubber, increase the minimum
weight and prohibit delayed launch.
Note that I take phone input for SCAT Electronic News
from only a few people and Bob is one of them.
[note Bob's message arrived before the recent annoucement
of the FAI agenda]
Vikane, Methyl Bromide, Termites and Rubber
===========================================

Roger,
Vikane (not vicane)is not a methyl bromide derivative. Its chemical
name is sulfuryl fluoride. Very nasty stuff, but extremely volatile
with boiling point (-)68 degrees F. My guess is that it is probably
more reactive than methyl bromide, but since it evaporates so rapidly,
it isn't around long enough to cause rubber damage.
Chuck
Modeller's Perspective

"Cowley"
Roger,
· Re Methlyl Bromide: Now that aeromodels are all-composite,
why even worry about Termites ?
[that's true Martyn, especially as I have given up my wooden
model box and gone to a metal Batiuk Box and I knew
there was a reason why I didn't like wood props ]
Methyl Bromide
---------------

This bromide is not your everyday headache reliever. It will relieve the
headache by killing the body and mind action.
MB was the chemical of choice for aircraft fire prevention at the time I
started work with the Glenn L Martin Company in Baltimore in 1950 - a major
aircraft firm. How long it had been in use, I do not know. However, it was
gone in about 5 years, replaced by something else.
I would not think of getting near the stuff.
Bill Bogart
[spoken like a true termite..]
[conclusion .. that Vikane is probably not harmful to rubber -
but I'm not going to risk my remaining Jul 97. I thank
fellow F1B flyers who offrered to store it for me ! but
think it would be safer with a non-modelling friend ! ]
