I can see myself in Canada or Alaska one day needing coolant and finding no waterless coolant anywhere, while conventional coolant is everywhere. Plus, I heard these 912's tend to run cold. So do we really need Evans? My engine has run previously with coolant in it, but it has been drained out for almost 2 years. I suppose it would still need to be flushed if I end up using Evan's.

Does your 912 run hot? How much coolant does your engine take when you change it? Do you have to "vent" the cooling system like you did the oil when changing it? And thanks for the info on the oil. But I'm confused with oil change procedures? I hope this doesn't sound stupid, but do you drain the oil tank as well as the crankcase every time you change oil? The fitting on my tank is a real bear to get at. But it looks like if I don't I will have a good share of the oil in the tank yet. If so I'm thinking about installing one of those easy open valves that are available. But I'm not sure there is room up there for it? How do you do yours? Has anyone tried an extended line with a valve at the end like they use in the marine industry. Sure would make life easier if that tank has to be drained every change. Anyone using the full synthetic oils? I had a bad experience with synthetic in a car once years ago, and have been leary of it ever since. But if it truly is better for the engine today, I would use it. I would imagine I could extend my oil change intervals (here in wisconsin you fly all you can while the weather holds out :-) Times a wastin' when you have to change your oil...

Evans is recommended due to the hotspots that can develop in the 912 heads when water is used in the coolant. No water so the boiling temp is way higher. That's why it's used in performance / racing applications. I've always run 100% antifreeze as here in Houston hotspots are an issue. I changed to Evans as 100% antifreeze can gel over time but Evans won't. There was a good article in one of the mags (Sport aviation or Experimenter) and Evans was recommended in the article. Just my choice...

I fill a jar with brake fluid and drop the fuel pump in. I hook the fuel pump to the bleeder on the bottom of the brake caliper and then replace the plug in the top of the brake fluid reservoir canister with a hose barb with a hose that runs back to the jar. I have a momentary push button set up on the fuel pump so I can bump it, running it wide open creates to much pressure and pops the hose off the brake caliper. I work the brake pedals as I am bleeding, it goes quick and works great.

I tried that method and it will not work for these Cleveland brakes because they have a check valve fitting on them and they will not allow a simple rubber tube to run the fluid in. It needs a special fitting that I will probable have to purchase in order to do this right.

It recommends this oil if unleaded fuel is used exclusively and your runnning temps are in the 250 range. It doesn't discourage the oil if temps are below that, but it does recommend other oils if occasional 100LL is used.

That said, the reason I am using the oil from the accepted list is that an I used to use and previously listedt was delisted because of the the EPA mandated formula change on that brand of oil (Motul 5100). I began using an oil formulated and sold by California Power Systems (a Rotax distributor). Eric said they were planning on testing that oil for the foaming problem - nothing yet. I have discontinued using that oil. Keep in mind that the reason for the new dipstick was at least in part to compensate for the foaming issue. Rotax has published a number of bulletins regarding the problems of air in the oil system and this is an area where caution is appropriate as it seems to me that the vibration issues with our engines - spinning a prop - is a bit different than a motorcycle, spinning a chain. I'm usually a bit skeptical of manufacturers claims if it has to do with recommending their own products etc. but Eric spent a bit of time on this issue last year at OSH and it got me a little concerned.

I did some testing using RC model servos and even with tons of gear reduction, you can see the motor pulses if you pan the camera. I suspect you will see the same thing with the mirror activator. I am going to eventually mount a high res digital still camera and that is one possibility, though. One more possible problem with the mirror unit is that the speeds are constant with a directional off and on switch and a proportional pan would be impossible. I was thinking that I didn't use a proportional pan that often, but I do. Especially when flying with another airplane and trying to keep it in the field of view or tracking something on the ground. I have tried just about everything once and sometimes more than once. If anyone is interested in my failures, drop a note and I can at least let you know what didn't work for me. One late trick. I bought a new highrer resolution camera and surprise - when it came it didn't have an external microphone jack. How do I get air to air and ATC sound into the final video. Since there is very little syncronized sounds and editing is not a problem, I got an IPOD photo with enough capacity to record every sound for about 5 and a half days. I turn it on just before take off and shut it down after the flight segment. I had fouund that most of the good chat was during the more boring stretches when the camera was off. I misssed too much of the good stuff. Now I get everything. I listened to some of the audio from our last Idaho trip and as I listened to one approach, I could feel the adrenaline rush as I relived the event. Maybe this has to do with why music has such an emotional effect. I found the sound with no video much more moving than the video without the sound.
