Hi David, I hope to be able to fly in if other commitments allow so
please let me have any special joining instruction. I will be flying a
C172 as my Europe's still a pile of bits!

10 days ago, we postponed the proposed fly-in at Shobdon from 28 April
to Sunday 4 May. 3 days ago, on the basis of all the forecasts for
tomorrow, we postponed it again, from Sunday 4 May to Bank Holiday 5
May.
This message is to say that, if there is anyone out there who could
not come on either Sunday, but could and would like to come on Monday 5
May - you are very welcome to do so; just e-mail me please, or leave a
message on my mobile 07970 292936. There are "joining instructions", and
it would be helpful for any extra attendees to see them before arrival.
Monday does look better; it is just darkening up for Sunday's rain as
I write (1745 Saturday)!
David

Hi All,
Yes to Grahams point, the fuel gauge system that Tony designed
calibrates to any shape. For those who aren't aware of Tony's gauge
system it works by weighing the contents of the fuel tank. It uses a
sensor in the lowest point of the tank which is connected to an
analogue to digital converter. A microprocessor uses a set of look up
tables that you create during the calibration processes to compensate
for the tank shape. The output can be either a 10 segment bar graph
or a signal to drive a conventional analogue meter.
Although not as simple, this system gets around the issues associated
with sight gauges, and IMHO, is far superior to any capacitance or
float system
I have had mine in place since May 2004 and it has worked faultlessly.

Here's an article I found informative on this topic.

A friend who used to race shared this company's name.
They're apparently the gold standard for fuel cell bladders
in the racing world.
http://www.atlinc.com/racing.html
He also suggested that most rubber bladder tanks have
2 major drawbacks:
1/ 5 year lifespan
2/ Temp variance effecting fuel capacity (range typically is 30=BAF to
120=BAF (0=BA to 50=BAC)
I've also attached a .pdf which includes a "Product Safety Bulletin"
section.
Rather keen to get this issue resolved!

Alan,
Could you elaborate on the products and techniques used in your
attempts to repair the old tank?
I apologize for asking you to open old wounds, but your accounts may
allow us to focus better on finding something that just might work.
No doubt folks will tend towards solutions which address the situation
in which they find themselves. For some, a metal tank will be the
obvious solution. For someone w/ a bulging but no signs of a leak,
another strategy may be persuasive. For myself, w/ an empty tank
installed which has yet to smell any fuel, I'm looking hard for a "fill
and drain" agent which I can slosh around the tank interior which will
provide an impervious coating to keep fuel out of the HDPE and hence
eliminate the tank expansion as fuel would be otherwise absorbed.
Because of the widespread use of HDPE tanks in the automobile industry,
and the relatively rapid evolution of both HDPE and fuel formulations,
my hunch is that there are hundreds of thousands of HDPE tanks which
are vulnerable to current and future fuel blends. If that is so, there
will be huge need and market for precisely what I'm looking for.
Cheers...as they say, "better living (and flying) thru chemistry"
Fred

Subject: | Tailplane torque tube troubles |
I installed the tail plane torque tube a couple of days ago and strayed it with
AFS-50 then wiped it down with MEK. I noticed that the plating is flaking off
on one side. I sent an E-mail to John asking him what he thinks I need to do.
Are there any ideals? Have it replated, buy a new one?

Mine (kit no 505) did the same in 2002. I returned it to the factory
who arranged to have it re plated. The second attempt worked fine.
