One item more I can take off my to-solve list. Frans ________________________________ Message 3 _____________________________________ Time: 02:58:14 AM PST US From: Frans Veldman Subject: Europa-List: static and pitot wing connectors Hi everyone, I thought to be smart and ordered from RS the "upgraded" versions of the standard Europa static and pitot connectors. These are not floating but have a thread and nut so I can fix them on the fuselage. As a bonus (I thought) they have an automatic valve that closes when they are not connected, so no moisture or bugs can creep in. So far so good. The system is leak free (as tested with a syringe to simulate pressure changes), over a couple of hours indications of ASI and altitude didn't change. However, I noticed now that with the wings disconnected, when the ambient temperature or pressure changes, the instruments start to indicate airspeed and altitude values, because the pressure inside the static and pitot system can not vent. Of course the pressure difference will leak away over a couple of days, but the leak rate of the pitot and static are not equal so in the mean time weird things happen. One thing that concerns me is what would happen when the pressure in the pitot is lower than in the static port: the ASI would want to indicate a negative value. This will happen when the ambient pressure increases and the leak rate of the static port is higher than the pitot. Should I abandon the idea of using the connectors with automatic valves? Or should I intentionally introduce a small leak between static and pitot so ambient pressure changes will not wreck havoc with the instruments? Has anyone else a similar setup?

These are only used to remove the filters for cleaning. My feeling was that they are something else to fail so I did not use them on the pitot and static. I would not want to introduce a controlled leak between pitot and static.

Bugs in the tubing would be far worse. You made the right choice. I near never disco the wings, so I use the Winter 5 hose connector which is not self-sealing.

I'm finding Nuckoll's book informative, particularly because he has an overall schematic (Z-19) for a "Dual Battery, Single Alternator, Electronic Controlled Fuel Injected Engine". (I know, I know...a stock Rotax installation would be way easier for me.)
