One of my fellow Gung Ho classmates volunteered that he still didn't understand the Ammeter & Voltmeter. The example given to answer the question made an impression on everybody: Water, in the local municipal water supply system, was monitored.......the "Pressure Gage" was equivalent to the Voltmeter, and a "Flow Meter" was the Ammeter. It was stated that if you could see both values you could then speak to the existing conditions. We were reminded of Ohm's Law.....that knowing TWO values (volts & amps) would allow us to easily calculate or visualize conditions. This is not to say you NEED both, but if you have room in the panel its sure nice to see what happens when you turn stuff on or off, and watch the meters respond to changes. With the usual small-capacity battery and alternator/charger normally found on GA aircraft it is easy to overload the system with too many DVD players, stereo music systems, autopilots, landing lights, electric seats & windows, windshield wipers, etc. Onboard radar, threat detection equipment and electric tailhook retractors are optional. A Merry Christmas/Happy Holiday Season to all.

After toying with doing aluminum plenums (saw a 601 with such an arrangement but didn't care for the looks) I made my own with fiberglass. Turned out really good. This is the last stretch for me, after the cowling is done I can fire up the engine for testing. Now the question I have is that I cut a NACA-style duct on each side (different sizes, the main rad needs to be bigger) and I'm wondering if they will be adequate to scavenge enough airflow to cool the rads? The 601 I saw with the AL plenums had scoops glassed into each side. The main rad scoop was a glassed-in 4L bottle of windshield was fluid. Didn't look that bad but the current owner ended up cutting ahead of the scoop on the main rad to get things cooler, effectively creating a rudimentary NACA duct ahead of it. So should I take the time to glass in a scoop on each side as well? I have pictures of the cowling work on my picture website here: http://pagefamily.homeunix.org/picture_album/view_album.php? set_albumName=album15 Thanks Trevor Page 601HD 98.5% complete ________________________________ Message 3 _____________________________________ Time: 08:38:29 AM PST US From: Mike Fothergill Subject: Re: Zenith-List: 601 Cowling ducts... --> Zenith-List message posted by: Mike Fothergill Hi Trevor; I think you are using a 912 engine. If this is so , you do not need any openings in the side of the cowl to get sufficient coolig. There is more than enough air entering the front. The key is directing it to the radiators, particularly the water rad. The oil rad does not need a lot. Then directing the exhaust air out of the rad down to the low psessure opening at the bottom rear of the cowl. Pics available if desired, even though mine are all aluminum.

I have a sealed duct from the back of the rad down to the extraction area at the bottom of the firewall.

With the costs of present day systems it just makes more sense to move in that direction now. Some systems to consider are http://www.para-aviation.ca http://www.dynondevelopment.com of course there are many more and you can find some from the commercial pages on the www.ch601.org website. But the two above are my personal favorites. Are you dated? Yes but so are most of us building an airplane, I bought a full panel of steam gauges for my Zodiac when I started but now they will be used in either a 701 or an Osprey 2 whichever I build next. Before I get to many E-Mails on that last statement, I have no intention of traveling any type of distance in either a 701 or the Osprey 2 but the 601 will be a cross country cruiser.
