It is around 5 years old with 300 or so hours on it, and I think it is a terrific aircraft. I do have one problem with it though that somebody may have met before. The ASI seems to read around 15kts high all the time. The aircraft has no external static pressure source so it gets its reference from inside the cockpit at the ASI instrument. The previous owner says that this is the cause of the problem, as the pressure in the cabin is significantly lower at speed, but I am not sure this is correct. As I am coming to the CH601 with a totally Cessna background for the last 20 years, the airspeed indication at point of flare is quite critical on the short narrow strip where I keep it. Has anybody met this before?

Yes, the ASI will always read high in this case. 15kts seems like a bit much though. Perhaps the ASI is also inaccurate. As long as the ASI is consistent and you have the correct approach speeds, using this ASI, this should be a problem. Since it is an experimental you are perfectly legal to replace the ASI and/or install a proper static system. --- ________________________________ Message 3 _____________________________________ Time: 08:47:52 AM PST US From: "Ed" Subject: Re: Zenith-List: ASI accuracy --> Zenith-List message posted by: "Ed" I have read reports of people having their shirt sleeve "sucked" out the canopy joint and have had the same experience myself. This would tend to indicate a lower pressure outside the canopy would it not? I have dual (balanced) static ports at the rear fuse and still have -5 kts indicated (probably the instrument) Ed 601HDS (ASI -5kts) do not archive ________________________________ Message 4 _____________________________________ Time: 08:58:14 AM PST US From: "Don Walker" Subject: Re: Zenith-List: ASI accuracy --> Zenith-List message posted by: "Don Walker" Yes, Richard, we have all run into this. Most have put an external source for static pressure. Mine is near the tail, and now seems to be reading around -3 mph. However, if you will just stall the airplane and determine your stall speed, then you can fly safely either way I think. don walker HDS TD 263 hours ----- Original Message ----- From: "Richard McLachlan" Subject: Zenith-List: ASI accuracy > --> Zenith-List message posted by: Richard McLachlan > > Hi folks > > I am new to both this list and Zenair, having just bought a CH601HDS > yesterday.

Now that winter is here I have trouble getting up to temp. I have a question: If I use a shut off valve to cut off the flow thru this heater core on cold days, will it harm the pump in any way? And will this affect the functioning of the thermostat. Do any of you know what kind of thermostat the Stratus has in it? On the stock Stratus this loop goes uncooled and unrestricted..any good reason for that?

It allows some coolant to flow even when the thermostat is closed. It brings coolant that is warmed by the engine up to the thermostat in order to warm it up so it will open properly when the engine gets up to temperature. If your engine is slow to warm up, you may have to block the air flow through the heater core until the engine warms up and the thermostat opens. You may also have to block off part of the air flow through the main radiator to reduce the rate of cooling in order to keep the engine temperature up. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru.

However, make sure the cap is secure and it's stored tip down and it should last a lot longer.

Sharpie markers --> Zenith-List message posted by: Carlos Sa Hi, Michel I bought a set of 5 Sharpies three years ago (before Nov 99, at least), and am still using them, no problems. Just bought a second set because a couple ran dry (completely). I keep the cap on when not in use, and store them verticaly, point up or down, it does not matter. Sometimes I have to trace a short line (<1 cm) top get them started, but that's all. Note: temperature in my workshop (in basement) is always above 17 C. I erase Sharpie traces with nail polish remover. Maybe it can also be used to jump start the little suckers...? Regards, and have a great New Year Carlos > That's it!

Sharpie markers --> Zenith-List message posted by: Michel Therrien Thanks Carlos... may be my garage is a bit too cool. For erasing the Sharpie traces, try lacquer thinner from Canadian Tire. Works very well and most probably cheaper than the nail polish remover.

First thing I've ever gotten into that my wife really doesn't want me to do. Racing motorcyles? No problem. Flying airplanes? She's convinced I want to make her a widow. Anyway, I digress. Watching this forum for a few days (and reading Michel's post about having 1500 hours into his plane already), I'm wondering about the time estimates on Zenith's site. You guys are actually doing the building, how realistic are they? If I do actually buy an XL, I suspect I'll be doing a turbo Subaru conversion, as I live in Colorado, with base altitude of about 5k feet, with 12,000' mountains 20 minutes east. How many of you are using the Subarus? Whose conversion? I'm not worried about the turbo end of it, that's what I do for a living. Lots of questions, I'll have more as I go along, so bear with me. Any and all advice/input welcomed!

I stopped logging at 600 hours because it was almost done, and I stopped carrying builders insurance. This is the first plane I ever built. In fact, this was the first time I ever really built anything. I have the Stratus Subaru engine. It isn't turbo, but I'm happy with it so far. I have had my plane up to 15k feet and still climbing. I would have gone higher, but I didn't have any oxygen.

Thwing" Subject: Re: Zenith-List: Grrr... those ?#%! Sharpie markers --> Zenith-List message posted by: "Randy L. Thwing" The ink seems to "harden" on the tiny flexible tip. Lay the pen against the metal at about a 30 degree angle, push slightly to bend (not break) the tiny flexible tip and rotate the pen barrel 720 degrees (that's two revolutions for you Canadians) while holding the tip in a slightly "flexed" position. This seems to "crack" the hardened ink on the tip and allows fresh stuff to start flowing. Keeping the cap on tight has never helped, they "harden" every time. I can't accomplish much building airplanes, but free advice is never in short supply. Randy L.

As a reference though it took me 650 hours (400 advertised), but I do have a full instrument panel and a couple others modifications from the factory plans. I have a Stratus engine, normally aspirated. Again, HD not XL, but I have no problems with service ceilings or runway lengths. It still only took about 1/3 the runway at Leadville, although it was a cold day. -Bruce/601HD/TDO/Stratus Black Forest, CO (base alt 7k feet, 14,000' mountains 10 minutes west!) > If I do actually buy an XL, I suspect I'll be doing a turbo Subaru conversion, as > I live in Colorado, with base altitude of about 5k feet, with 12,000' mountains > 20 minutes east.
