I've just been through the tach wiring thing. Use the gray wire if you have one. If you don't or it doesn't work, tap into one of the 2 lighting coil wires (thick yellow and yellow/black) that go to your rectifier. Leading Edge techs say these will work too. I presume its the same for all tachs using ignition pulse to count RPMs. I put a 1K ohm resistor and a 500ma fuse in line between engine and tach for my installation. Shielded the wiring against ignition noise too. Seems to work fine.

It sheds light on Tom's experience with his Stratus soob - and his reasons for getting a newer model Courier. Bill ================================================== From: "simko55" I'm new to the group, but been around the Courier for a while. I built my first in '94, powered it with a Stratus Soob, and enjoyed 1300 trouble free hours with it , finally all the little model changes added up to enough good things to make me sell it last fall and a day and half latter I picked my new S7S kit up and have started covering today (control surfaces). I'm going with a 912S this time round, mostly to save time, I surely hope its as trouble free and smooth as the Soob, its for sure more $$$. Everyone on this group knows a Montague folding full size mountain bike fits a Courier like they were made for each other, right? At some point I will post some pictures of my expanded baggage area (using aircraft plywood), cargo deck (which fits in the rear seat area, quickly removable), and the aux baggage door (it access's the bay between the main baggage area and the stock battery access door. Of course its just good for light stuff, but it does let me get at the ELT easier.

Today we installed the static port in the left side tail position as described by one of the early postings. We had the turned aluminium fitting which goes on the outside of the fabric, made up an aluminium plate to go inside the fuselage, used fabric over it to protect the fuse fabric and then riveted through with 4 aluminium rivets. Luckily we had put an inspection panel on the under side of the fuselage there so all went well. When we are flying I will post the speeds and see how accurate we are.

Thank you, Jim. Yes, I can, and have made a make-shift hole on my left side. I went flying both yesterday and today. Beautiful weather here: CAVOK, timid but warm sun, no wind, smooth ride in thick cold and motionless air, with a smooth Jabiru; a dream! But ... I still read a too high speed. Then I started checking my static line. I read that, to check for leaks, you can carefully suck from the end then use your tongue as a closing valve. You look at the instruments: Speed and altitude should stay there, VVI, of course, goes back to 0 fpm. In my case, everything goes back to 0, hence a leak. But where? Then I suddenly lost comprehension. If the VVI dial goes back to 0, as it should, it means that the instrument has a tiny hole that evens the pressure after a while, right? But if it does that, how can I expect the pressure (or rather, the under pressure) in the static line to stay the same? Am I missing something? I certainly am and it is why I ask my good friends on this list: what is your experience and where do you think my leak may come from? FYI, the static line starts at the ASI, to the VVI, to the altimeter, to the transponder altitude encoder, and aft to the tail. I use 4 mm line and fittings that are made for that line. The system is supposed to transfer pneumatic pressure up to 25 bars.

If you use a "long" static line the vent port must increase in size, as there is more "air volume" in your system. Did not think about the risk of mud, but I've seen this on my tail too, but I'm not that often out in a muddy field. :) Well, there might be a risk - but that double will help here..

I'll guess that you have a brand new line, so prob. that leakage is in the front. 2) Just before starting removing anything, check your ASI for internal leakage, -yes you'll need a very low pressure (be careful here) to see that the bellow between the two chambers is airtight, no leakage allowed here. This verify that inside the bellow is airtight. Go to item 4, item 3 is for testing the ASI for a leakage. 3) Then we need to check the outside of the bellow, the instrument housing. Here we check that there is no leakage between the housing and outside, this is the static port, also here be careful with pressure. It's important that the static pressure used here is lover than our current pressure, else the needle go backward just easy to ruin something here. Use a long line to avoid "direct" high humidity into the instrument. The pitot input must have positive pressure, same procc. with a long line.. 4) Here we go if the airspeed is OK., we can now be sure that this is a static leakage, right, you see a leaky airspeed ind. can act as a static air leakage. Lets assume it is in the front. Disconnect the static from the ASI (air speed indicator), seal that line and make another test. The VSI (vertical speed indicator or VVI vertical velocity indicator) has a built in reference chamber. This camber bleed out (or fills up depending if we go up or down), so you'll see its quite normal that the altimeter go up as it should, then go a little back -this is due to the little "memory" chamber inside the VSI. When we make an altimeter test, we connect (or tie) the static and pitot line together, but first we carry out the pitot part. In your case, its best to disconnect the ASI to find this static leakage. Well, you see it's not that difficult- just isolate that leakage I'm sure you will. Good luck. Torgeir. > But ...

Thank you, Torgeir. Yes, I will test my instruments for intern leak. But I can't figure out how the VVI works. If it senses a difference of pressure through the static line, moves up or down, then goes back to 0, it means that the instrument has a restricted leak, doesn't it? In that case, the leak must affect all the other instruments connected to the static line, doesn't it?

The memory chamber is just a little accumulator with a calibrated leakage between, -then we have the bellows connected in between.. Yes, when doing a test in a closed system the VSI or VVI have a little influence, but in the air the instruments is connected to the open atmosphere (the outside) filling up immediately. Here the extra "air" for the little accumulator (inside the VVI) make no difference for the other instruments. Torgeir.
