(trevord) ________________________________ Message 1 _____________________________________ Time: 12:11:45 AM PST US From: Tim Ward Subject: Re: Europa-List: Larger oil cooler - Classic Hi Michalm, Best solution is to reposition the oil coolant below the spinner. An alterat ion to the lower cowl with a inlet for the oil cooler. Easily done with comp osite experience or get someone to do it for you. No bull nose required just keep with the original profile. See photos. I have to place a barrier in wi nter to keep the temperature up 110C Rotax prefers the engine to run at. Wor ks very well.

I have the standard cooling setup with a 10 row oil cooler behind the port ra diator and slightly enlarged cowl outlets. On hot days (30 C) and loaded to m ax weight I very quickly reach 120 C oil temp during a climb of just 2000 ft . If I let it cruise a bit it will go down to 115 C within a few minutes, 11 0 C if I reach cooler air higher up. The coolant stays below 90 C, except th e climb phase where it reaches around 100 C. So far after reading your past d iscussions I came up with 2 possible solutions: > 1. Moving the oil cooler below the spinner. > 2. Installing an oil/water heat exchanger to supplement the oil cooler. > > The first is a bit invasive and as I'm not the original builder I don't fe el fully confident to perform, yet. The second one is tempting but I thought about trying a simpler solution first: exchanging the oil cooler for a larg er model. Mocal makes various sizes - the 13 row should fit without issues a nd perhaps the 16 row version will fit as well (if it can clear the exhaust p ipe). > > Has anyone tried this approach? How effective this may be without enlargin g the cowl outlets? According to charts on Mocal website I should expect a r eduction of oil temp of around 8 C (16 row vs 10 row), but that assumes a fr ee air flow which is most likely not the case inside the cowling. > > > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=501888#501888 > > > > > > ========================== ========= ========================== ========= ========================== ========= ========================== ========= ========================== ========= > > > ________________________________ Message 2 _____________________________________ Time: 04:16:40 AM PST US From: Bud Yerly Subject: Re: Europa-List: Re: Water Drain I still don't like plastic slip on filters.

Back to the filters: Most of the fuel filters of this "type" have poor quality casings, have ple ated "paper" type filters and many are opaque (making it impossible to asse s contamination build up) The Hengst H102WK & H103WK are almost indestructible. Have gauze filters an d clear casings - they are more like $10 each Australian, if bought singly but you can get them down to about $6 Au if purchased in quantity. Like you, I was initially skeptical of the non "barbed" male hose fitting. However using the right sized ID hose, cut to the correct length and suppo rted, where appropriate, has resulted in 12 years/900hrs of no leaks, no in advertent detachments. One other benefit of the non barb, is that the possibility of tearing the i nside of the hose, when temporary removal is done, is eliminated. This then eliminates those troublesome little bits of "rubber" that may appear in yo ur float bowl. The H103WK has a built in 90 degree bend, making tight applications that wo uld benefit from this a breeze. -------- 46 Read this topic online here: https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fforums.ma tronics.com%2Fviewtopic.php%3Fp%3D501885%23501885&data=04%7C01%7C%7C3 f6be0a3020e4c5f4dfd08d915bdceb2%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0% 7C637564727224891711%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2 luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=D%2Bd67kxttQNtcXal% 2BdlU9Px5CUFJdL3emTo5b4v5hPw%3D&reserved=0 %2Fwww.matronics.com%2FNavigator%3FEuropa-List&data=04%7C01%7C%7C3f6b e0a3020e4c5f4dfd08d915bdceb2%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C6 37564727224901704%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luM zIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=b1BPzjeBYosZMV9jTqbMeK Oz%2F8q8%2BV0sBhJh1Vha%2FGU%3D&reserved=0 %2Fforums.matronics.com%2F&data=04%7C01%7C%7C3f6be0a3020e4c5f4dfd08d9 15bdceb2%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637564727224901704%7C Unknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiL CJXVCI6Mn0%3D%7C1000&sdata=ayKPY%2Bj0MmZm7xWJW2XZBtf0AHfrHwBN9K5U4lRZ M8k%3D&reserved=0 %2Fwiki.matronics.com%2F&data=04%7C01%7C%7C3f6be0a3020e4c5f4dfd08d915 bdceb2%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637564727224901704%7CUn known%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJ XVCI6Mn0%3D%7C1000&sdata=bsOVpHmgB5FyQ8CoXZnn0nT4p9MMXR2NjFtjAYOZ9J4% 3D&reserved=0 %2Fwww.matronics.com%2Fcontribution&data=04%7C01%7C%7C3f6be0a3020e4c5 f4dfd08d915bdceb2%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637564727224 901704%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6 Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=3jgGJv8oSJMKkXIgdOb7bsaW6%2B%2BcK %2FdTS9sJolrVEtk%3D&reserved=0 ________________________________ Message 3 _____________________________________ Time: 04:16:20 PM PST US Subject: Europa-List: Re: Larger oil cooler - Classic From: "Griffo" Just to expand the conversation and possibly take a lateral approach: Most people assume you must have a heat exchanger (coolant radiator and oil coolers) located at the front of the cowling, however I have seen several set ups (not Europa) where the heat exchangers are located in non traditional positions, such as above the engine, even in the warm exit air about to depart the cowling. The message; dont assume as far forward as possible, is the only location. -------- 46 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501907#501907 ________________________________ Message 4 _____________________________________ Time: 04:21:15 PM PST US Subject: Europa-List: Re: Water Drain From: "Griffo" Oh well "you can take a horse to water but cant make it drink" Just as a final comment: I first came across these filters being used, as prefilters, in Mercedes diesel cars/vans. I later found that many of the European LSA class aircraft makers also use them - quit a long way from a lawn mower. -------- 46 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501908#501908 ________________________________ Message 5 _____________________________________ Time: 07:53:27 PM PST US Subject: Europa-List: Re: where to put OAT sensor? From: "trevord" Has anyone considered the wheel well ? This space is out of the sun, there is lots of room and the wall I have inserted to stop mud going into the lower fuselage is flat on my aircraft, so perfect for mounting things to it by simply drilling a hole. I have to install several OAT senders due to installing two uAvionix AV30s which each require a separate OAT sender. Plus there is a third OAT sender for the Kanardia Airspeed indicator to give TAS. Would stray exhaust really be a problem here ?
