One listee said he would rather use conventional coolant...that way if he was on a cross country and needed to top up the coolant he had a good chance of being able to obtain it... Evans being less likely to come by. Sounded reasonable to me, and although some of the techy benefits of reducing hot spots sounded appealing, I never made the switch. I was at a seminar a couple of weeks back and a gent from a certified Rotax repair station giving a presentation on maintenance of the 912 made a comment that struck home. He said that the Evans runs a zero pressure. That is why there is a new cap for the reservoir. The standard 50/50 glycol mix runs at about 10 psi..and goes up with altitude. If you have a leak in flight with the glycol, there is a good chance you will loose a lot of the fluid, probably loose the engine. With the Evans, there is a good chance you will make it down since the fluid will not rush out of the system. My guess is that you will see the leak on the ground in your walk around, as I know of no way you would detect it in the air unless it was kicking up smoke...but still it sounded like a valid point. Enough to make me make the switch. That point may have come up in previous discussions and I missed it...but thought it was worth revisiting. Any thoughts?

Maybe someone could refer me to the change. The mandatory bulletin that added Evans coolant just said to put a sticker on the existing cap. Somewhere in the past I thought I saw a Rotax document that revised the cap pressure set point but cannot find that document either. Need help, Thanks, Paul PS, My cap is 0.9 Bar which is 13.2psi and I was going to add a pressure gauge to monitor the pressure to notify me of a leak. Of course the presenter made an erroneous comment about the pressure going up with altitude. Fact: The cap maintains an constant pressure above ambient which decreases with altitude. This means a leak would be the same at sea level as it would be at a higher altitude because the pressure differential would be the same. The comment someone made about replacing Evans coolant while flying cross country. Maybe if that were to happen the flight should not continue until the leak was found. I believe many hot rod shops sell Evans coolant. In any event a quick call to Evans would locate a source locally or overnight to where you are.

Serialize complete at 09/09/2005 04:42:16 PM --> Kitfox-List message posted by: kitfoxjunky On the mag side of the engine there are several black coil pickups. Depending upon the design of the pickup (there is an old and a new design), there is a range for the gap between the pickup and the cam on the part that rotates with the engine.

The spring does not put the elevator in any different position than the pilot would without it. You are just letting the spring do the work instead of your arm. So, NO elevator range is lost at all! Also, without flaps, the force from the spring is only enough to bring the elevator to the neutral position. When flaps are added, the spring is stretched and it applies more force to hold the elevator. ________________________________ Message 13 ____________________________________ Time: 02:16:32 PM PST US From: PWilson Subject: Re: Kitfox-List: Evans Coolant in the 912 series --> Kitfox-List message posted by: PWilson This subject needs to be side tracked ASAP. There is no such thing a zero pressure liquid Evans included. The vapor pressure may be less that a E Glycol mix but if you loose coolant the pressure will rise until it stabilizes at the boiling point. BTW, The Evans coolant specified by Rotax is NOT 100% Propoline Glycol I think it has EG and other chemical in it to meed the Rotax requirements.

Did you know about coil pickup gapping?? --> Kitfox-List message posted by: "Donna and Roger McConnell" Gary, This was discussed a couple of weeks ago when I brought up the subject. I was having problems getting my tach to read right. It was recommended that a range of .016 to .020 should work. I also learned that if your tach still doesn't read right, meaning the needle pigs all the way to the right, you can wire in a 100 to 200 ohm resistor across the leads coming from the pickup. I had to do this and my tach looks like it is reading right. I plan on having it checked to make sure it is accurate.

Also, if any of you have the old carb heat box installed, please make sure that the box mounting bolts have castle nuts with cotter pins. DO NOT use lock nuts, not even metal AN nuts, they can and mostly likely will eventually come loose. This is one of those things I really wish I hadn't learned the hard way. Cliff PS. this goes for any bolts on the carb heat box. Just examine the box and imagine any bolt coming loose, where will it go?

I have had the Evans coolant in my turbo EA-81 application for a big 75 hours now. I feel the benefits far out weigh the need/chance for a remote refill. This is a long term benefit analysis, so I am not prepared to give the engine tear down analysis yet. The expansion rate is higher than regular coolant. One of the benefits of that is the coolant acts as its own thermostat. When cold it flow slower allowing warm up and when hot thins out to facilitate cooling. Work for me.

If I were at high density altitude and coming hot...oh yea Kitfox hot, with the trim assist activated by adding flaps, then I might not have as much elevator authority as I would have otherwise had by just adjusting the elevator with the actuator ram. Is that right?

I haven't installed the instrument lighting, but I went up anyway with a flashlight, though I didn't end up using it. I could just make out the white hands on the instruments, and I knew where they should be - and I was able to keep altitude/airspeed very nicely. I climbed up to two thousand feet and just cruised with the doors open, enjoying the warm night air (a temp. inversion had already begun). A local airport - Sanford, ME, had one of the runways lit up like a christmas tree, complete with the "rabbit" for the ILS. Portsmouth, NH was gorgeous, and I even saw some fireworks! If it weren't for my buddy waiting for me on the ground, I would never have come down :) I started my descent and just crossed the threshold on short final when the runway lights went out. I fiddled with the handheld to turn them back on and then went around for another shot. I watched the landing light hit the pavement and made a greaser of a wheel-landing - absolutely perfect! I'm still grinning ear-to-ear, two hours later! What a privilege!

The trim assist does not decrease elevator authority.. it gives you more authority to hold up the elevator... I guess it may be named wrong.. maybe back pressure assist would be more appropriate, but trim assist it is. It simply assists you in applying the back pressure required. Without the trim assist... when on approach to landing with no flaps one can very easily trim the aircraft for a hands off approach. However, introduce flaps and then re-trim.. one runs out of trim for hands off at the same given airspeed.. Therefore one needs to hold back pressure on the stick to maintain the given airspeed. The more flaps used the more back pressure required. For example: Debra could trim our 7 for a 60 IAS approach no flaps hands off just fine, but had a hard time holding the required back pressure for a 60 IAS approach with 1 notch of flaps and the aircraft trimmed. Now with the trim assist (back pressure assist) she can get the aircraft trimmed hands off for a 60 IAS with 2 notches of flaps. Hope this makes sense... Fly Safe !!
