I monitor my coolant temps but I don't rely or worry about them. The hottest I've seen it go is 182F, the norm being 169-180 depending on outside temps. My CHTs (more important) run 230-260 on front-rear. For me the Evans has cured my boiling problem of plain 50/50 glycol mixtures and stabilized my temps across the board. The only discrepancy I have is my engine being older has the oil temps being read by the front oil banjo bolt location on the bottom of the engine which reads a bit higher since the oil has circulated in the heads. Newer engines read the oil temps at the oil pump after going through the cooling rad. My oil runs 245F on hot days, recently they've been 220 or so. If it gets colder I'll have to tape off the rad a bit.

Well, after a year of not working very much on my plane I got back on to it over the last week. I had hit a wall on the forward fuselage and was stupmed until I downloaded ALL of the new photo manuals and went back over everything I'd done. I figured out the errors I'd made, ordered new forward fuse skins and am back in the hunt. BTW you guys who are just now getting kit parts don't know how lucky you are the pre drilled holes in the skins really help. I'll have some new pics on my website www.peoamerica.net/N601WR before the end of the day. ________________________________ Message 7 _____________________________________ Time: 07:07:26 AM PST US From: Larry McFarland Subject: Re: Zenith-List: any form blocks for sale? --> Zenith-List message posted by: Larry McFarland What model aircraft you looking for Evan?

Some customers have indicated that they would like to go straight for their Private Pilot certificate in an immersive, accellerated fashion, rather than first getting their Sport Pilot ticket. As a result of this customer feedback, MASPL is now offering a 16 day Private Pilot immersive course at Sky Bryce for $8490 (includes King ground school and practical flight school DVD's, 40 hours of aircraft time, 25 with an instructor and 15 solo, MASPL's Ground School Plus, private or semi-private instructor, 16 days lodging and practical test). In other words we give you the minimum FAA requirements (except we give you 25 flight hours with an instructor instead of the fAA minimum of 20) for the PP license. If you need extra days or hours to get sufficient proficiency to receive a sign-off for your FAA checkride, the cost is $100 per night lodging and $110 per extra flight hour with instructor or $70 solo (wet). The 1-week Sport Pilot course costs $4290.

Aircraft Spruce has them http://www.aircraftspruce.com/catalog/topages/handrivetsqueezer.php for $135 but I can't tell if includes the yoke or not. You'll also need a couple of the flat squeezer sets and MAYBE a dimpler set or two. If you're an EAA member, ask around at the next meeting. I'll bet someone has one they'll loan you.

If there appears to be enough interest, a custom combination of cowl and radiator may be designed and tested. There are several CH-701s using the standard cowl and same radiator design with the Suzuki engine. It is possible the existing radiators may need to be somewhat larger to accommodate hot weather and high altitude operations, therefore, the custom combination for the above mentioned aircraft.

Phil Lockwood told me 3 weeks ago that either 50/50 or Evans could be used, so to confirm I called him back today. He told me that it wasn't a warranty issue and that either could be used. The main thing to watch out for is that with 50/50, the temperature should not exceed 248f. If it does then the system should be drained and the coolant replaced with the Evans. My 912UL typically ran around 210 on both the oil and coolent temps and since the 912ULS tends to run hotter, along with the expected higher temps from the Evans, I'm going to first try the 50/50. I'm also installing a different oil cooler bought from Lockwood, that Phil says should lower the oil temp about 20 degrees, and therefore the coolant temp should be a little lower also. The new oil cooler will require a modification to the lower cowl, but fiberglass is pretty easy to work. If anyone on the list has had other experiences along these lines I would sure be interested in hearing them. I'm probably 1-2 months from an engine start, so still have time to change my mind. And to do a little more research! If I do continue on this path I will post results.

You want to wear protective equipment. I do it in the garage with a respirator and keep the garage door open. I wouldn't want to do it in the house. My wife has a great sense of humor, but this may tip the scales. Definitely want to turn off the furnace. I sprayed some last winter. I waited for a fairly warm day and heated up the garage. Then opened the door. When done, and the fumes cleared, I closed it back up. Seemed to work ok. There is another option I am thinking about. AFS at http://www.aircraftfinishing.com/ has a waterborne product that looks promising. I ordered a quart of primer and a quart of finish to do the interior. I figure if I like it, I will paint the outside with it. They suggest an acid etch and then their primer. I think it may be fine. And a lot healthier. This stuff is kind of expensive. But you know every I try to save a couple of bucks I seem to pay for it later. This is not a project for the faint of heart or wallet.
