Any issues with swinging the compass, or calibrating the unit due to interference from other avionics, or from the Rotax engine? Many thanks.

Please tell me if you are happily using E10 fuel from petrol stations without ill effects. Until this year we in the UK have been using E5 car fuel, but have been officially informed that from September the garage fuel pumps and nozzles will be showing E10. Of course this is causing some concern and discussion in the flying community, with many stating that they will feel forced to start using UL91 which between 40% and 50% more expensive per litre. Someone was telling me today that EU pilots have been using E10 for many years without noticeable problems. Is this true? Thank you.

Depending on your location in the UK, Esso Synergy Supreme +99 has no ethanol and an octaine rating of 99 see here https://www.esso.co.uk/en-gb/fuels/petrol. I have been used Esso Supreme since 2013 and checked every batch for ethanol - there is none. Although I haven't checked, I understand that some other 'premium' fuels are ethanol free. Don't be fooled by the labels on the pumps 'E5' means up to 5% ethanol, so some are ethanol free. Premium grade fuels do not have to change to E10 yet, check the forecourts and you will see that the premium fuels are still labelled E5. My advice is to check out your local supplies of Premium grade fuels and check the ethanol content yourself using one of these https://www.parts4aircraft.com/alcohol-in-fuel-tester It's also worth checking SL-912-016R2 from Rotax Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501649#501649 Attachments: http://forums.matronics.com//files/sl_912_016r2_914_014r2_essential_information_regarding_engine_behavior_performance_and_manifold_pressure_data_for_rotax_engine_types_912_and_914_series_135.pdf ________________________________ Message 4 _____________________________________ Time: 01:46:30 PM PST US From: William Daniell Subject: Europa-List: Charge warning light I have standard z 16 I have a charge warning light and a dynon efis and ems This morning the charge light stayed on for about 5 mins albeit glowing not lit. Normally it goes out within 1 min. The dynon said 13.8v and 6 amps from start up and my battery charging amps were normal also. Does this mean anything apart from some kind of fault with the light?

Most people I know in the Europa family and several others using Rotax engines in different aircraft types, have no qualms at all about E10 in their engines. As you say, it's the "the fuel tank, fuel lines and electric pump" which give more concern. But I've been informed that there's no such thing as ethanol free car petrol such as Esso Synergy Supreme and other "super unleaded" brands in the whole of Scotland and parts of Northern England, which all get their fuel from the Grangemouth refinery regardless of brand name. From September this year, all car petrol from Grangemouth will continue to have ethanol of at least 5% and 10% in ordinary unleaded. Furthermore a friend's Eurofox experienced partial engine failure after take-off due to using Esso Synergy Supreme from a local garage, probably stale fuel due to low sales turnover. He only just managed to get back onto the runway unscathed! After flushing out the fuel system and filling with ordinary E5 unleaded, there's never been another missed beat in his engine. So my question remains to be answered by EU pilots and particularly Europa owners who have been using E10 for many years, as far as I know. Please let me know if you've heard of any problems experienced by any pilot and/or Europa owner after using E10 petrol for a long time. Problems not only to do with carburettor icing and vapour lock, but also the fuel tank, fuel lines and electric pump. Thank you.

04:02:15 PM PST US Subject: Europa-List: Re: Question for European friends re E10 car fuel From: "JonathanMilbank" Hello Steve, One of the joint owners of the Eurofox said he gave it to a daughter (or granddaughter, not sure) who is a scientist in the petrochemical industry, to be tested. I never saw the results, but was given to understand that the fuel was stale. Furthermore when the fuel was put into a mower, the mower wouldn't run. After the Eurofox only just managed to land unscathed back on the runway, I personally got involved with the draining and fuel replacement and saw the samples taken for testing. Naturally the garage owner hotly denied any suggestion that his tank was to blame. This was all personally witnessed. And I still want European pilots and owners of EU based aircraft with Rotax engines, either Europas or other types to answer please. Experiences, anecdotal or otherwise, from UK sources aren't what I'm after, although I appreciate your concern. Thank you.

Using an Earth-X battery and can set voltage setpoint and low voltage warning to be in tune with LiFe battery as Bud mentioned. As far as your problem, if I wanted to keep the Ducati regulator (for a while anyway) check the fast on connectors. For a while Rotax was not supplying the best Fast-Ons. If you begin to get a bad connection a lot of heat will build up at that connection due to high resistance. You can buy a B&C AVC1 field kit that includes phosphor bronze fast ons.: file:///C:/Users/PARIGO~2/AppData/Local/Temp/Replacement_Regulators_for_the_Rotax.pdf Change at minimum the two yellow AC connections. Clean all blades on regulator, slight bend all fast ons to give a little more tension. I put on a dab of CRC 2-26 for good measures with a make up cotton applicator: https://www.amazon.com/Pointed-Cotton-Double-Precision-Makeup/dp/B07Q4RW17G/ref=asc_df_B07Q4RW17G/?tag=hyprod-20&linkCode=df0&hvadid=385587032845&hvpos=&hvnetw=g&hvrand=11942724094879087823&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9004516&hvtargid=pla-840098427530&psc=1&tag=&ref=&adgrpid=77764998959&hvpone=&hvptwo=&hvadid=385587032845&hvpos=&hvnetw=g&hvrand=11942724094879087823&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9004516&hvtargid=pla-840098427530 BTW these work great for precision application of grease like on wing lift pins and sockets etc. AFC-50 could be used. Depending on your battery, you can increase voltage set-point. If you put a diode in series with the sense wire, it will raise voltage. For AGM 14.2 or so or with LiFe you could go a tad higher. Start with 1 diode in series, you could add two in series. I must mention I haven't tried it, but was planning on it if I used Ducati. A regular diode has a higher voltage drop compared with a shottky. If one wasn't enough and two in series was too much, I was planning on tying one regular and one schottky. Chances are B&C AVC1 is a little more efficient compared to Ducati, but best as Bud mentioned keep either cool. I have mine living in a box on top of the starboard footwell with ambient air being fed from the top of the 914 air cleaner NACA plenum. I have an electric fan to keep box reasonably cool after shut down or during taxi. Good luck. Ron P.
