The radiator has a large plug in the back, with two tabs - obviously the water temperature sensor. The question is - how have folks installed the rear radiator cover? That is, have you cut out a large hole (about 1" diameter) for the wires to go through and to clear the plug, or have you drilled a smaller hole in the cover and run the wires through that hole, or ??? It seems like the cover should be as close to the radiator as possible to cut down on air leakage, but then it interferes with the tabs. Thanks for any help and advice.

Make sure you have a good seal to prevent any air from escaping in any way besides going through the radiator. -Andy On Sun, 22 Aug 2004 11:21:55 -0400, Bill Steer wrote: >--> Zenith-List message posted by: "Bill Steer" > >I'm installing the radiator on my 601HD with the Stratus Subaru >engine.

It won't give you a temperature reading, only on or off. I bought a replacement for mine a month ago at the prospect of using a fan one day, but later, found the fan wasn't needed. For access, I cut a 1-1/2" hole that clears the plug for a large socket and then made a cover with two holes and used rivnuts in the back cover to hold the small plate. There are earlier pictures of my radiator when the plug was reworked to hold a schrader valve to bleed bubbles from the high end. That didn't work nearly as well as making the radiator attachable only after it is filled with coolant.

Given that I have to trash the centre spar, I am considering the switch to the XL model. I am trying to get as much information as possible, so I can make a informed decision. This is were my project stands today: Tail feathers completed. I haven't built the wing tanks, and the outer wing spars weren't rivetted yet. all ribs ready Fuse work hasn't started, although I have a number of parts made. The choice - So far, I see as advantages: simpler construction centre spar simpler construction main landing gear no wear problems on main landing gear (less maintenance than the HD) nicer looking (opinions will vary, of course) improved attitude on landing (?) due to flaps performance (?) The figures I found don't show much of a difference... Disadvantages: I'll need to make new forming blocks (some sixteen or eighteen) additional work: flap building requires a 12' table (I'm thinking of adding a 4' temporary extension to my 8' table; workshop is 12'6" long...) of course, a whole bunch of parts go to the recycling bin Comments/suggestions/opinions welcome Happy building/flying Carlos do not archive --- Cdngoose <601xl@sympatico.ca> wrote: > --> Zenith-List message posted by: "Cdngoose" <601xl@sympatico.ca> > > Hi Carlos I just checked my plans and the wing lockers are there.

Mine is 50mm X 850mm. It's fine most of the time, but I run out of NOSE UP trim at low speeds, especially with the flaps out on approach and low power settings. It's not too difficult to hold the pressure and it may be a safety factor to have it that way, but I'm wondering if I should fit a larger tab.

I have so far no information or drawings whatsoever, but my quick build fuselage (everything else is slow build) come with this option that comprises an extra transversal tube over the cockpit with an inner extendable coaxial tube at each end and two simple angled wing fittings, delivered as separate items. CZAW did not include any documentation or drawings for this option. I have not been able to figure out how to install it nor figure out how it works, but there it sits staring at me. I know it is an unpopular option (even ZAC does not really promote it) as the wings are easy to detach and quick connects can be arranged for the fuel and electrical wires, but before throwing it away and burning the CZAW delivered wooden trestle, which I suppose is used to hold the wings close to the tail, it would be nice to evaluate the usefulness of this option. You see, I will have to tow my amphibious 701 past some obstacles every time it will be stored, so this option could perhaps after all come in handy. best regards Max PS Jim, be sure to include zenith or 701 in the subject line if including attachments. >< Zenith-List message posted by: "Jim Fosse" > > Max.

The plug on the radiator is a thermo switch for a fan, you won't need to use it. I just cut the contacts off of it and left it in as a hole plug. I did not cut any hole in the back of the radiator cover for it. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. Construction complete.

From: "Lance Gingell" --> Zenith-List message posted by: "Lance Gingell" Today, I did the same...put the lock washer underneath and ground it all down. After this I had plenty of clearance, so I didn't bother with the access cover. I think the key is to move the lock washer, and to grind down the plastic washer to about half its thickness (ZAC send me pics like this)...at that point, its all pretty low profile. If I hear back from ZAC on the access cover I'll post back...
