If I'm not mistaken, there's one more practical issue to consider. Water conducts heat more efficiently when in liquid form, but if it 'boils' locally (i.e. on an engine hot spot) then the resulting air bubble will not conduct heat away. So, the addition of the 'antifreeze' maintains the water in a liquid state to prevent this.

It really comes down to what you need. In my case I was looking for a relatively fast cross country cruiser with good altitude performance that would suit my low hours as a pilot. The fact of the pop rivets and simple build were not important in my selection. Hence when I found the thing was both not fast and not high I felt cheated. I then found a lot of other benefits so I actually like the little HDS to fly. Its interesting my original requirements are still very much big factors that will affect my decision. I was talking to a guy at the weekend who spent 17k on a pretty nice 4 place Comanchi. If the performance claims for the 640 turn out as they did for the HDS I would think something like this would work out more economically even if I had to do owner assist maintenance. Just a thought.

It's the standard plans-built tank, and has barb fittings, 3 out the top, and 3 out the bottom. Looks like it was set up for flexible fuel hoses to be connected. On the bottom, the center outlet has a finger screen. The other 2 on the left and right point downward. On the top, one outlet has a 90 degree elbow to the side, and the other 2 point straight out toward the instrument panel. I know I can't use all these outlets, so I was planning on plugging the unused ones, assuming I retain the header tank. Maybe one of the top outlets can accomodate a fuel level sender of some type. And I thought about pumping fuel from the locker tanks into the bottom outlets since there's more space to work there tan at the top of the tank. Thanks for your help.

Maybe not. Actually the most efficient heat transfer in a forced-convection system happens when "nucleate boiling" occurs. These are small vapour bubbles that form on the hot surfaces and are then pushed into the flowing coolant, where they collapse again. This way the heat-of-vaporization is also removed from the hot surface, which is significant. You are correct that if the coolant is allowed to boil so much that it becomes mostly vapour instead of liquid, then you're in trouble. I think if this were to occur in our systems you'd know it because the pressure-relief cap would lift. -Bruce/601HD/Stratus/TDO/375hrs ________________________________ Message 14 ____________________________________ Time: 09:12:20 AM PST US Subject: Re: Zenith-List: Rotax Cabin Heat?

Thanks Ray. I'm not an engines expert but I think this is similarly true for all engines. They are usually only rated for full throttle/full rpm for a few moments, then there is a max. cruise rpm setting below that which we are allowed to use if we don't mind high fuel consumption. My point was just that the great speeds that the Jabiru 3300 is finally giving on the Zodiacs, only comes thanks to more 'ooomph' than Zenair originally speculated -- I mean specified ;-).

If your aircraft is in the proper envelope (i.e. the Weight and Balance), then that's as is should be and is a different issue than the nose-up attitude in flight. If your aircraft NEEDS 20lbs more weight in the tail to make the Weight and Balance numbers work out better, then why not add some of this in the form of a heavier battery? At least that way you're getting 'something' (more cranking power, electrical power) for the weight as opposed to 20 lbs of dead weight. (Someone else mentioned a tailskid as another idea). Does Zenair have a specific weight limit for the tail-mounted battery? They approved my rear battery rack installation but required me to 'beef it up' with extrusions as opposed to my original idea of 'L's for the frame. What is your aircraft's center of gravity now? Is it near the forward or rearward limit? Once you are sure that the CoG is always correct during a flight, (i.e full fuel/minimum fuel; 1 small pilot/ 2 BIG pilot/passenger; No baggage/ lots of baggage; Wing lockers?) ... then the next issue is the attitude at different speeds, and the amount of control and trim authority you have.

Sufficiently satisfactory results were achieved with "BASF Glysantin Anticorrosion". This or an equivalent coolant has to be used. ATTENTION: Take note of the specifications from the antifreeze producer. NOTE: If problems are encountered with boiling after engine stop, increase percentage of antifreeze gradually. In all cases, antifreeze to water ratios should not exceed the antifreeze manufacturer's recommendations. Exceeding the antifreeze manufacturers recommended ratios can lead to the formation of particulates in the coolant solution or inadequate protection against freezing. ATTENTION: Particulate formation may be harmful to cooling system components and may restrict coolant flow to and from overflow bottle." Further, "Summary * Use of a brand name of high quality antifreeze with corrosion inhibiting additives is recommended for ROTAX 912 and 914 engine series. * Antifreeze used must be mixed with water as per recommendations of the antifreeze producer to create a coolant solution suitable for the complete temperature range of the engine and to provide adequate protection against freezing. * Coolant solution should be checked with a densimeter or glycol tester to verify protection level. * Antifreeze to water ratio of 50 / 50 is required in ROTAX 912 and ROTAX 914 series engines."

I will eventually build another, but with 2 flight schools, and a full time job as a high school teacher, I won't be starting a new one soon. -----Original Message----- From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com]On Behalf Of Weston, Jim Subject: RE: Zenith-List: New plane moment --> Zenith-List message posted by: "Weston, Jim" Congratulations Phil. Did they give you a good deal, since you didn't take them up on a good deal for a new kit? Happy Flying, Jim Weston -----Original Message----- From: Philip Polstra [mailto:ppolstra@mindspring.com] Subject: Zenith-List: New plane moment --> Zenith-List message posted by: "Philip Polstra" I just picked up my brand new Alarus CH2000 at the factory today. Not quite as awesome as flying the Zodiac for the first time, but pretty close! ________________________________ Message 27 ____________________________________ Time: 07:49:09 PM PST US From: "Mark Townsend" <601xl@sympatico.ca> Subject: RE: Zenith-List: wing tanks --> Zenith-List message posted by: "Mark Townsend" <601xl@sympatico.ca> Kind of a let down when you discover that your Guru isn't perfect isn't it. At first Gary's word was gods message to me. Then I found a few errors and later found out that he has to this day never built a complete airplane. He is still a wise man in my eyes and knows a lot more then I do , but now I seek a second opinion on a subject.

Just wait until I talk to Gary. So has anyone made any glass or epoxy tanks for the XL? David
