----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- Randy, Coupes usually have a combined pitot/static device under the left wing. This tube is fairly thick, maybe a half inch. The front end has a cup shaped opening with the pitot opening. Arrayed around the tube of the cylinder are four static ports. The multiple ports take care of neutralizing the static pressure when you have changes of attitude. There should be TWO tubes running from this device to your pressure instruments. There's a specification for how far the tube should be from the wing surface and I've heard of some problems in accuracy when this isn't met. Sorry I don't know that detail. This pitot/static tube combination is a nice idea in my ignorant opinion and I'd like to get one to use in my Challenger II Ultralight/Light Sport Aircraft I'm building. If anyone has one from an old junked-out Coupe wing, please let me know and we'll talk.

I then found that my Ercoupe has no static port. I have 2 coupes and upon checking the other one I found it to be the same. Is this common? How can I (Can I?) install a static port or correct the problem? Do I need to? I am planning on upgrading the venturi, installing a vertical speed and D.G. Any help would be appreciated.
