No pictures of this, but I can take some next visit to the aircraft if anyone is interested. I=92m also considering the addition of another LED string to the interior aft fuselage, behind the =93D=94 door for additional interior work illumination. The LEDs provide plenty of light, can be dimmed and use very little power. Blue skies & tailwinds, Bob Borger Europa XS Tri, Rotax 914, Airmaster C/S Prop (75 hrs).

Tank had already been installed at time of writing=85my kit # is A-194, purchased in year 2000...I=92ve yet to put any fuel in my tank, but expect to do so in the near future. I do have a rig with which I can rotate my fuselage and create a certain amount of =93sloshing=94. My question is: Was a =93sloshing agent=94 which would reduce fuel absorption ever discovered, or is my note just a bit of wishful thinking? Fred ________________________________ Message 4 _____________________________________ Time: 04:48:05 PM PST US From: Fred Klein Subject: Europa-List: RG393 coax All, In my as-yet-non-airworthy Europa, I=92m about to replace the RG58 coax originally installed for COM and XPNDR antennas. Both my newly purchased COM and (mode =93S=94) XPNDR are part of the Dynon SkyView suite. Dynon sez the RG58=85though perhaps adequate for the COM...will be very unsatisfactory for the XPNDR, and the folks there refer me to =93Antenna Cable=94, p. 230, (chap 11-p.12) in the SkyView installation guide where various coax cables are considered. (I cannot seem to include a link to the SkyView Installation Guide) On p. 231, (chap.11-p.13) there is a chart which appears to state that RG400 (M17/128) is fine IF its length is less than 8=92-4=94. I find that this M17/128 is the spec. for the RG400 sold by suppliers like Aircraft Spruce, SteinAir, and B & C. The chart also lists an RG304 for lengths up to 12=926=94, and RG393 for lengths up to 17=92-3=94. There is also a link below the chart to manufacturer=92s data which is more specific=85there is clearly a special realm reserved for coax cables. I=92ve located a source for the RG393 where I can buy a minimum of 100 feet at $6.89/ft=85and I=92m having trouble swallowing. I=92m skeptical of the notion that SkyView customers are using coax other than the widely available RG400 (M17-128), and I=92m VERY reluctant to spring for this RG393. I do intend to replace ALL of my RG58. Can someone who has some keen knowledge on this subject give me some guidance? =85with appreciation, Fred ________________________________ Message 5 _____________________________________ Time: 05:56:12 PM PST US Subject: Europa-List: Re: RG393 coax From: "rampil" Sounds like gilding the lily to me. It's just a question of attenuation at the 1 GHz range. My SL-70 uses RG-400 just fine. Is Dynon suggesting that their transponder output power is weak and they need every femtowatt to not be lost in cable? -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=431925#431925 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message europa-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Europa-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/europa-list Browse Digests http://www.matronics.com/digest/europa-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
