For instance, this one generates a web page with a black window where the video should appear, but then it just sits there: http://www.rotax-owner.com/all-videos/expanded-video-instructions/39-exp-si-27-010 Anyone else having this problem? Paul Kuntz ________________________________ Message 2 _____________________________________ Time: 08:23:57 AM PST US From: "AJR" Subject: RotaxEngines-List: 912uls cooling Hi Guys I have a zenair ch701 which has a 912uls engine..I recently put this aircraft on full lotus floats and it gets off and flies good however it seems that the oil temperature is going higher then normal,,I sometimes see the temperature a 230 and more after take off It has the air scoop for the oil cooler on the passenger side and I widened the scoop for more air The guide says 190 to 230 is the most favourable operating temperatures. I consider it to be high as I usually see temps in the 200 =93210 area..also when I check the oil and follow the test of rotating the propeller and listening for the gurgle in the header tank I do not hear it..I am using the mobile MX 4T racing oil as suggested... what is the oil filter part number and which is the best suggested replacement filter to use..what does the group consider normal temperatures for the 912ULS engine all advice and suggestions would be appreciated Happy flying AJ Rose ________________________________ Message 3 _____________________________________ Time: 08:58:20 AM PST US Subject: RotaxEngines-List: Re: AeroElectric-List: Re: Rotax 912 UL alternator drop-out From: Paul Kuntz Several inputs suggested checking the connections on the leads coming from the alternator, and checking the system ground connections. I checked the faston-type alternator lead connections, which were clean and tight. I checked all of the ground connections, which were also tight. Yesterday I went up for a test flight and confirmed the symptoms under varying system loads. The normal system voltage with alternator on line is 13.8 volts, which is consistent with what others are reporting for the Rotax Ducati regulator. I see a max load of 10 amps with everything running, so I am satisfied that the total load is well within the standard Rotax system capacity. I also observed that the system voltage drops to 13.5 volts at the 10 amp max load, which seems abnormal. Under this max load, the alternator dropped out after a few minutes, indicated by system voltage dropping to around 12.5 volts -- consistent with fully charged lead-acid battery. When I reduced the load to 3 amps, which is my practical minimum (one Dynon display, radio and transponder), the alternator came back and stayed there, with system voltage at the normal regulator set point of 13.8 volts. I repeated this experiment a few times for various loads, finding that a total load above 5 or 6 amps will cause the alternator to drop out after a few minutes, and that it will come back when the load is reduced to 3 amps. I am pretty well convinced that my voltage regulator is bad. I did learn from comments on this issue that Van's includes a voltage regulator cooling kit with its lighting kit for the RV-12, consisting of a length of plastic tubing that connects from the air intake duct to a shroud over the regulator, providing a direct blast of cooling air to counteract the increased electrical load of the lighting. So there is certainly indication that the Ducati regulator is susceptible to overheating under load. The RV-12 regulator is on the engine side of the firewall, however, and mine is on the cabin side. At 10 amps with the regulator mounted in the cockpit environment, I'm thinking the regulator should be able to handle the load without supplemental cooling. Others have noted the not-so-good reputation of the Ducati regulator, but there are thousands of them in service on Rotax engines worldwide, so rather than tackle a reconfiguration of my regulator and wiring installation at this point , I ordered a replacement Ducati from Lockwood Aviation and will see how it goes. I also ordered a overvoltage protection module from B&C, since the Pipistrel electrical system does not include one. I'll install it with the new voltage regulator. I'll report my findings after installing the new regulator. Paul Kuntz On Sat, Aug 10, 2013 at 10:21 PM, Paul Kuntz wrote: > Thanks for the tips, everyone.

_____________________________________ Time: 10:23:46 AM PST US Subject: RotaxEngines-List: Re: Rotax 912ULS Stumble below 4000 RPM on final ONLY** From: "rampil" Here's another thought. I have a similar issue in my 912s, at manifold pressures from 22 down to 18 inHg, the engine gets rough. If I advance the prop to more FINE, the rough range narrows. This would speak for overloading the engine or lugging, not under loading as initially suggested. Over the years I've have several conversations with Phil Lockwood, Dean Vogel, Bud Yearly and others. The most likely, but still unproven in my case, is Bud's thought that in-flight one of the carb slides sticks. Bud has seen a carb replacement cure the issue. I may try it myself when I fly down to Sebring for my ten year maintenance. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=406972#406972 ________________________________ Message 7 _____________________________________ Time: 11:08:54 AM PST US From: Robert Borger Subject: Re: RotaxEngines-List: Rotax Owner videos not working Paul, First chance to test and, sure enough, just a black screen where the video is supposed to be.

You may want to set your prop pitch to achieve at least 5600 -5800 rpm at WOT flat and level. Adding the drag will automatically increase the oil temp. No big deal as 230F isn't an issue. If you fly in the Southwest US 230F is an everyday norm during the hot months. Up to 240F doesn't bother me, but mine seems to be good at around 230F - 235F in climb and around 220F for cruise (OAT 95-100F). My prop can achieve 5600-5650 rpm WOT flat and level. Use the correct oil filter. Rotax Part #825-012. Many years ago the difference from an automotive filter to a Rotax was negligible, but not when they came out with the latest oil filter. The automotive filter by pass pressure is only 12-15 psi and years ago the Rotax was 13-16 psi. Now days the Rotax by pass pressure is 18-22 psi, the filter has a check valve in it not found in an automotive filter and a much softer better designed anti drain back membrane. It still has a paper element, but there are now significant difference so stay with Rotax. Of course there are those that say I have had an automotive filter on for a while. This is like smoking cigarettes. One cigarette or even one pack won't kill you or cause a disease, but a life time is deadly and causes debilitating diseases. You own an expensive engine and an expensive one to repair treat it right and don't cause yourself any avoidable long term headaches and wallet strains. -------- Roger Lee Tucson, Az.
