(propeller speed of 90 rpm.)." One thing I have found with the Rotax manuals is that the information is all there but it can be extremely difficult to find at times. It has just taken me about 25 minutes to find the info above even though I last read it only 4 days ago.

From experience the engine will not start if it does not turn at that rate. I don't have my manual with me but I'm pretty certain that 200- 300 RPM is insufficient. Hope this helps.

The lamp circuit is optional for the installation. Dave When hooking up the engine the Instalation manual suggests a 4 watt -12 volt light bulb be installed in the circuit. Today I have tried to find one and haven't been able. It is supposed to light and indicate charging. For 200 hours I just used a 50 ohm 10 watt resistor to protect the voltage regulator. It needs a small load all the time. That works but I would like to try the suggestion if I can find the bulb. Does any one know of a source? By the way someone asked about a source for the 23,000 micro Farad capacitor rated at 25 volts in their circuit. I found that Radio Shack has a 25,000 micro Farad rated at 50 volts. It is physically large, but it works fine.

Don Walker ----- Original Message ----- From: John Karnes To: zenith-list@matronics.com Sent: Friday, June 27, 2003 12:27 AM Subject: Zenith-List: Stratus cooling data --> Zenith-List message posted by: "John Karnes" I've been wrestling with some cooling problems with my Stratus EA-81 and I seem to have worked them out. Here is what I discovered: After reading all the info on moving radiators further back where there is "undisturbed air," I moved my radiator back about three feet and ran hoses along the bottom of the fuselage to connect to the firewall. That is when all my problems began. Last summer, I started having all kinds of problems and eventually resulted in a BAD overheating event and "unscheduled" landing 50 miles away. I tried putting a scoop on the front of the radiator before this event and it still didn't work. After a rebuild and some engine trial runs, it appeared that the engine was running rich (a lot of carbon deposits on the plugs) so I leaned the main jet on the Bing out one notch. When I took off, I had a lot of power but the temps rose alarmingly on a brief climb out. Sooo.... I moved the radiator back to the edge of the firewall as per original instructions, made the mixture rich a notch on the main jet, and wrapped the exhaust with thermal wrap. When I took off this time, the water temp rose to about 210 and stayed there. Man, what a relief! My advice to my fellow "airsoobers": Leave the radiator up front behind the prop (even though this makes no sense to me), make the mixture rich enough (check by looking at the spark plugs), and wrap exhaust with thermal wrap (as per Jim Weston's email). I'm looking forward to a long summer of "frequent flier" miles!

I'm not familiar with the "UL" plans, but with a set of my 601XL plans, I could add baggage compartments to my airplane (if it was finished). Installing and removing gas tanks on a regular basis doesn't sound like anything I would like to do, but I'm sure you could modify your airplane to do this.

I believe that 5052 is the alloy for welding up tanks and formed fairings as it doesn't crack. Structurally, it is not as strong. Do not use it when another stronger alloy has been specified. But wholesale ban an alloy from aircraft when it is used in many certified planes is not correct.

I have nav/strobe lights, extra wing tanks, and will have folding wing option. So do any of you have advise of where the wires and fuel line leave the wing and how much should I leave on to get to the next fitting or connector? Are connectors usually located at the wing so that it can be removed if needed? Where is the fuel line and wiring usually run in the fusalage? Where does the shut off and gascolator go? Seems odd that they haven't included a simple schematic or drawing showing the typical routing for these items. Maybe it's there and I just can't find it.

The change in mixture is easy to accomplish. take off the top of the carb, remove the diaphragm with the main jet attached. Remove the screw in the tube and the jet will come out. Take off the tiny clip (be careful and don't drop it!) and move it down a notch to make the mixture more rich. Re-assemble.

You get better heat transfer but increase water pressure, when the water starts boiling you're out of luck for cooling. I understand that 50/50 is a save number for the EA-81.

What coolant mixture are you using? I used the 80% recommended in the Rotax manual and had bad problems. Then an old RR Merlin mechanic saidto me,"change that to 50/50". The problem disappeared for ever! The heat transferance tables tell you that as well. Dave Austin 601HDS - 912
