I will be flying a C172 as my Europe's still a pile of bits! ----- Original Message ----- From: David.Corbett To: Europa Forum Sent: Saturday, May 03, 2008 5:45 PM Subject: Europa-List: William and Paul - Memorial DOTH 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)!

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.

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.

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? ________________________________ Message 7 _____________________________________ Time: 11:19:38 PM PST US From: "G-IANI" Subject: RE: Europa-List: Tailplane torque tube troubles Mine (kit no 505) did the same in 2002.
