I haven't yet read the actual final rule, so I don't know what it really says. So far, we are all going on someone else's interpretations. EAA SHOULD have it pretty well understood. It sounds, now, as though they're saying that stall speed in the LANDING CONFIGURATION makes no difference! In other words, a plane could stall clean at 46KTS, but have very effective flaps, and stall dirty at 20KTS, and they would say it doesn't qualify for LSA status. Time will tell whether that interpretation stands. If it does, there's no way an HDS can ever qualify as an LSA. The only recourse would be to build a set of HD wings.

It's not an interpretation, It is very clear in the rule; all you gotta do is read it. One stall speed; Clean (Vs1), or as the FAA words it "without the use of lift enhancing devices"; 45 knots. Also, in the original NPRM, you had to meet BOTH the 44knot "clean" stall AND the 39 Knot "landing configuration" stall speed. So the new rule does not eliminate any aircraft by the rule change. The Faa's explanation for this is on Page 81 and 82 of the rule.

Slower top end, but golden. However, Zenith says the HDS stalls at 54mph with 1050lbs, BUT 48mph with 800lbs (single pilot) The new rule says Clean stall at 45knots = 51.78mph. I wonder... you "might" be able to reduce your max load a bit in your operating manual (you are the manufacturer), assuming you have not flown yet, and list your stall at 45knots. You'd probably be safer (in compliance) converting to an HD.

There is more than enough room (at least 2.5" - 3" between the lights and the power supply). My only concern is heat. Anyone think there is a problem? Since I don't want to run shielded wire through the wing, the only other option is to mount it on the inside of the spar, which puts the spar in between.

I added vortex generators (that I made from scrap alum) to my HD wings. I know everyone "says" this will have NO effect on the fat HD wing, but I wasn't happy with my stall speed so I went ahead and did it anyway. I figured I'd have to mess around with 3 or 4 different locations to get it right if it would work at all. But to my surprise the first attempt gave my 601 HD a good 4-5 MPH improvement on my stall speed. So I'm happy and will leave them right were they are. Don't always believe what "they" say .... also every 601 HD, HDS, or XL may react differently with VG's, all I can say is I'm very happy with mine.

The real issue is the info you get from BOTH... A voltmeter will tell you about the condition of your battery state... but it could be TOO LATE! If you notice that you dont have 12 or 14 volts anymore.. let's say its down to 10 or less.. you have possibly lost your alternator/generator an HOUR AGO!.. and precious time has passed before you have a chance to take corrective action. If you had BOTH and ammeter and voltmeter... you could tell the second you started your engine that yes, you have your 12 volts, but that the alternator is not charging (ammeter showing a negative charge, normally it shows positive with the engine running) and you have knowledge that it will take some time (maybe an hour?) before your battery will not start your engine anymore. I would opt for an ammeter if I could only could have one meter, as a glance can tell you that you are not charging anymore... But I would always opt for BOTH... its all the info you could possibly need about your electrical system!

Assuming the usual "small" cutout, you can get both, as a "dual" from Westach. Don't have their catalog, it is out in the hangar, and its 98 degrees (too damn hot to walk out there) but as Jon says both will be more to your liking. The ammeter portion of the dual unit will have a "remote" shunt and a pair of wires to the indicator. This makes installation easy, simple, idiot-proof, etc. The most important instrument, however, is the fan connected to the tach. This item keeps the pilot cool. You can judge the effectiveness of this arrangement when the tach drops to ZERO in flight. This is when the pilot begins to sweat.

Hello Trevor, There are instruments that include dual meter movements or dual digital in a single instrument so you might be able to have space for both (see for an example).

No I did not do any testing of VG's on the canopy (to date). But I did place a pair under my cowl in front of my cowl exhaust opening and found this to help lower my oil temps by approx 5 degrees. I'm running a Stratus Subaru EA-81 and been having a hard time getting the air to flow thru my cowl for proper oil cooling. These little buggers do wonders if sized correctly & placed in the needed locations!

What did it do to the top speed? > Thanks > Ron DeWees Ron, Before my plane stalled at 55 MPH on my ASI (2,000 RPM & loaded to approx 1,000 lbs), and with the VG's installed I'm now down to 50 MPH in the same configuration, so the VG's gave me an additional 5 MPH. I only flew for 1/2 hour to test the stall so I'm not sure if it killed my cruise speed much or not ( but I did notice 107 MPH on the GPS with a 7 MPH tail wind @ 4,000 RPM).

I will tell you battery condition (state of charge) before you ever start the engine. Also if y our alterntor should fail in flight you can again monitor state of charge. In addition it will tell you the voltage setting of your regulator. None of the above can be told with the ammeter. It can only tell you the direction of current "net" current flow into or out of battery.

But I have had one fail out of a two light set in 8 years. But I do agree when it fails you must be able to get the Strobe power supply out. I recently relocated my strobe power supplies into the cabin from the orginal location on the outer wing spars. I did run Shielded wire from the supply to the Flash unit. The additional cost is around 60 bucks.

Ben Haas N801BH, do not archive ________________________________ Message 30 ____________________________________ Time: 11:47:31 PM PST US From: xl Subject: Re: Zenith-List: Ammeter or voltmeter? --> Zenith-List message posted by: xl I went with a voltmeter. But after I had a problem with a bad connection, it was one of my main power leads, I added an ammeter. I finally figured out the problem by looking at voltage drops across connections. But, in the mean time I wasn't sure if the problem was caused by the battery, alternator or something else. When the voltage drops the radio transmits poorly - I was told by ATC. The ammeter is useful. I can tell for sure if my alternator is working. I didn't go with an ammeter at first because I too was concerned about running the charging current through a shunt. But, I'm comfortable with it now. After a total cabin electrical failure during flight testing and the intermittent problem that I had later I'm less concerned about losing power. The plane will still fly. And I have a hand held radio. I don't want to lose my position lights at night though.... (On that note I do plan to add a second battery for my essential buss.) I used a small $7 auto ammeter. I riveted it on the bottom left of the panel. It's in the corner out of the way - above and to the right of the passenger's knee. It's only about 1.25 inches around. I'd go with both. Joe E. N633Z @ BFI 74 hours On Fri, 23 Jul 2004, Trevor Page wrote: > I'd like some opinions on which gauge type (volt or amps) I should > install in my panel?
