Rather than simple tubes to get coolant to/from the radiator, I'm usingthe same extrusions that Polaris snowmobiles have mounted underneath their running boards. Cross section is about 1.5" X .75" (slightly trapezoidal) with very small ribs on the top (bottom as mounted) of the extrusion and a flange about .3" wide on each side for riviting. I had a beaded hose nipple welded onto each end. It makes for a very clean installation and should add some extra heat rejection (cooling) at the same time. Those 6061-T6 extrusions are designed to survive in an extremely abusive environment with lots of vibration and impact. I am confident that they will work well in the CH-601 application.

I agree, that 3003 is probably much easier for flared fittings of small diameter and for bending around tight areas, but for me, a 1" straight 36" piece, well supported, should be a 5052 or 6000 series aluminum.

The one I was most surprised to find was that the 3or 4 anti-freeze additives deteriorate and are ineffective in a relatively short period of time. Nitrates improve heat transfer by preventing cavitation and bubbles for a 2-year period or so. When this additive goes, the engine can be overheating near the heads for a time without a good read on it til it's too late. I guess the question would be best asked, "How long since you replaced all of your coolant?" If your coolant is over 2 years old, take readings on your temps and then change the coolant completely and take another reading under the same conditions. I'd be very interested in what you find out.

It is a V-8 Ford and a 84" three blade prop. I made mine 1.5 degrees to thr right and .5 degrees pointed down.

It is, however angled. This is to correct for the common tendancy of most pilots to over-correct in the other direction. Were it not for this built-in feature unique to Chris Heintz designs you would fly in a straight line, go beyond the edge of the Earth, and, with the properties of gravity being what they are, fall off the far side of the planet. Reverse all the above of you fly left-handed. That explains things in the horizontal plane, but make no mistake, the vertical relm is somewhat different. We'll address that in the next installment. Sure you don't have it installed inverted? DO NOT ARCHIVE, for we have surely beaten this dead horse enough.

Remenber that the ZAC planes have full moving rudder, no triming can be achieved with the front part of the rudder, like in "normal" planes.... Maybe this is why ZAC compensates the p factor with the engine mount. What do you think? If you leave your mount straight you will take off like a P-51 or P-38 pilot :-) watch the pedals...

I bet it would be pretty easy to rig up a rudimentery pressure recovery duct from sheet alu. If you think about it, this duct does not have to be perfect because the air pressure loss through such a thin core is going to be pretty low. So I think covering the rad with a simple bent up sheet metal duct with the appropriate 14 deg tapered opening would be pretty easy to make. Might have to put a spoiler plate in the duct to spread the air to the outsides to prevent it barreling through the middle. I bet it would work though. One day I'll try it, but I think I'll use the 1.25 tubes.

If you don't use right rudder on the take off roll you will end up building ANOTHER 701... I have flown alot of certified planes with all flying rudders and they all had the mounts angled to the right too. I used the RV as an example because one cannot alter a certified plane legally. Now maybe down there in Mexico the rules are different and torque works the other way, ya know how things change when you cross the border. ________________________________ Message 20 ____________________________________ Time: 07:59:20 PM PST US From: "Cy Galley" Subject: Re: Zenith-List: Thinking about moving the rad --> Zenith-List message posted by: "Cy Galley" It would be neat to see how you built a beader.

There are other combinations possible here as well depending on the type of engine used. All I can say is that their engineering looks excellent and the visibility in daylight is very good (backlighting is also available). My plane is not yet ready to fly but I have seen a similar instrument in a flying 701 and the owner is very pleased with it. I am sure you would not be disappointed with the E2 and I am sure the price would be quite competitive.
