Eastern Standard Time, europa-list@matronics.com writes: >>>>>I know that this may be a little late for those of you who have already bought their strobe power units, but my installation works well without any interference. I have Whelen equipment and I mounted an HTS power supply at each wing tip. They are mounted on removable panels on the bottom surface. There is a weight penalty of about 1 pound compared to a single HDA power supply in the fuselage but all the high voltage cables are short and at the tip. No problems.<<<< Hey John and all, Follwing the K.I.S.S. principle, I used a single Whelen strobe power supply mounted to one of the vertical baggage bay support members under the port side of the baggage bay and my install does not cause any audio interference whatsoever. Access to the power supply is through the port access cover in the baggage bay floor. The power supply fires strobes on the wing tips with the cables routed from the power supply along the bottom side of the baggage bay, then along the sides of the baggage bay in the cockpit in fiberglass raceways which extend from the baggage bay bulkhead forward to the rear of the door sill. I installed these raceways along and over the fuselage seams on the sides of the baggage bay, covering the seam, as well as providing a conduit for wiring. The wires then pass down into the backrest and out the side of the fuselage through grommeted holes in the fuselage sides just behind the spar opening in the side of the fuselage. The raceways I made were molded over a piece of 1.5" PVC pipe cut lengthways to produce a 1/3rd round shape. Then with the PVC taped to a piece of plywood, 3 layers of 'bid were used to make the molding. A 1/2" flange was left either side of the rounded part to leave a bonding flange for bonding to the inside side of the fuselage. My system is quiet as a mouse without the faintest hint of strobe tick. The secret to keeping your strobes quiet first and foremost is how you ground the shield wires on the strobe high tension feeder cabling. The shield wires should be grounded only on the power supply end. I crimped, then soldered a ring terminal to the shield wire at the power supply end of the strobe wires, then landed the ring terminal under one of the mounting screws for the power supply so that the shield wire has continuity with the power supply case (which is grounded). Do not ground the other end of the shield wire at the light. If you do, you will create a loop antenna and a host of problems will follow. I used six pin Molex plugs and sockets at the wing roots and fuselage sides so that I would be able to disconnect the strobe and Nav light wiring when the wings are removed. The shield wire must also be carried through at this point. At the light end, I simply cut the shield wire off even with the cable jacket and stuck a piece of heat shrink tubing on the strobe cable to make it look pretty, allowing the strobe feeder wires to carry through a few inches beyond the cable jacket. The strobe feeder wires exit the end of the heat shrink, along with the NAV wires which are routed on the outside of the strobe cable, taped to the strobe cabling about every 6" along the length of the strobe cable and then carry on to the NAV light. I also installed 6 pin Molex plugs at the light to make for easy removal of the light if and when it fails, but the shield does not need to be included here. The plug/socket on the light end makes for easy removal of the light fixture for replacement of the strobe and NAV bulbs when the time comes or replacement of the fixture should it become damaged, but this step could be omitted. Another thing that is very important is to not route any other wiring with your radio and intercom audio wires, especially the strobe feeds and the trim motor wiring. Keep all other wiring separated from your audio wires by at least a few inches. I've installed Whelen strobe/Nav combo lights, grounding the shield in this manner, in 3 different airplanes thus far and all three are/were quiet as a mouse. Hope it helps!

    Hi all, I would like to have an indicator for the coolant temperature. However, there seems to be no connection point for a temperature sender. It seems to me that some of you have installed a coolant temperature indicator. If so, how have you achieved this? In some of the pictures in the album (forgot which one), I noticed that there are coolant "tanks" with a sensor hole in it, but mine does not have this provision. -- Best regards, Frans Veldman

    Hi John "The secret to keeping your strobes quiet first and foremost is how you ground the shield wires on the strobe high tension feeder cabling." I HATE YOU!!! Buying a Whelen power supply that dosen't exhaust noise form anywhere and everywhere. What sort of homebuilder are you? Not wanting to spend weeks tangling with noise. >From what I now understand, first and foremost is choosing a power supply that is quiet. Believe it or not on the Kunzleman, the quietiest thing about it is the high voltage output! I am not saying that if you don't ground the high voltage shield to box ground you won't get a little noise, but it is nothing compared to what comes out of the box, or what gets onto the power lines and radiates into the antenna and will get right into the cable if the cable is paralleled to power lines. One thing we found out, is shielded cable is a much better antenna than twisted pair for the supply line! We ended getting two Kuntzleman power supplies and are mounting them at wingtips. Makes no difference BTW if i use 12" or 25 feet of the wire supplied by Kuntzleman for high voltage, just that if you don't ground it, it makes a little noise and if battery runs down a little, will stop double flashing quicker with longer high voltage run. Fooling last night got box to stop breaking squelch with antennaat about 4 feet, so that is fine with power supplies mounted by wingtips. Fooling with various chokes and capacitors, got twisted pair going to battery to only break squelch if antenna is about 12" away. We also found that connecting the scope probe that is not connected to the scope completly eliminates all noise in radio! Art fooled on line a bit to figure out what is in probe, will get some more stuff to fool with. Don't have proper torroids or capacitors, but thus far looks like will be able to lick RF jumping off power lines. Bob N. from Aeroelectric sent out some filters to try out as well. Gut feeling is they will do the trick @ 2.9 oz each. Local IA swears by Whelen in TC, said he has noise problems with all others. I am gonna have to grab a plane taxing by and throw scope on it just to see, the Kuntzleman has hash and sharp peaks. Choke we triedeliminates all hash, sharp peaks need just a little more work.

    Hi Jeff, Included in my exhaust saga was a cracked heat shield as well. When the entire exhaust system was replaced, the new shield was redesigned to prevent what were analyzed to be thermal expansion induced cracks. The new system is still Aluminum from the OEM, but no sign of cracks in the past 50 hours of flight time. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=231258#231258

    Subject: tank support layups
    Done it again - come up against a query on a Friday after the factory tech help has gone off for the weekend! I'm trying to set up the tank for the T-shaped support layups. (1) the tunnel in the tank and the one in the cockpit module baggage area differ in level by about 30mm; the manual shows them more-or-less level with a layup sailing across. Also, the profiles of the tunnel are quite different on the tank and CM which makes the step bigger in places. I've put in the recommended 20mm spacer between the headrest area and the tank, and the bottom of the tank is almost flush with the bottom of the cockpit module, so things are correctly aligned there. Have I positioned something wrong, or is it OK to have a 30mm joggle in the layup? (2) how have people done the parts of the number 2 & number 3 layups that go between the tank and the CM? Seems they would need to be put in position with the tank slightly displaced from its correct position to allow room to work, but shifting the tank around doesn't seem a good idea if the number 1 layup at the front of the tank is already done. Any ideas? regards Rowland -- | Rowland Carson LAA #16532 http://home.clara.net/rowil/aviation/ | 1190 hours building Europa #435 G-ROWI e-mail <rowil@clara.net>

    Hi Frans, I suspect that picture you saw of a coolant tank with a sensor mounted in it was a modified unit that Cliff Shaw made. I did something similar. I took my tank to the Lincoln Welder demonstration stand last year at the Oshkosh airshow and had them weld a patch of aluminum on it to make it thicker so I could put a NPT thread in it. Although this approach is more elegant than putting in a T in the host, it does require a whole lot more effort. Just as an FYI, Grand Rapids also sell a T along with the appropriate sensor. Regards, Paul

    Yes mine was the same in the tunnel area, some areas being about 30mm out. I just blended it out as best as possible. I put a small amount of flox in these areas to help with the radius. As for the T layups I just spread the gap slightly by reducing the packing under one end of the CM to allow access into the area for the layup, then replaced the packing to close the gap again. hope this is some help craig -----Original Message----- From: owner-europa-list-server@matronics.com [mailto:owner-europa-list-server@matronics.com]On Behalf Of Rowland Carson Sent: Saturday, 21 February 2009 10:28 AM Subject: Europa-List: tank support layups Done it again - come up against a query on a Friday after the factory tech help has gone off for the weekend! I'm trying to set up the tank for the T-shaped support layups. (1) the tunnel in the tank and the one in the cockpit module baggage area differ in level by about 30mm; the manual shows them more-or-less level with a layup sailing across. Also, the profiles of the tunnel are quite different on the tank and CM which makes the step bigger in places. I've put in the recommended 20mm spacer between the headrest area and the tank, and the bottom of the tank is almost flush with the bottom of the cockpit module, so things are correctly aligned there. Have I positioned something wrong, or is it OK to have a 30mm joggle in the layup? (2) how have people done the parts of the number 2 & number 3 layups that go between the tank and the CM? Seems they would need to be put in position with the tank slightly displaced from its correct position to allow room to work, but shifting the tank around doesn't seem a good idea if the number 1 layup at the front of the tank is already done. Any ideas? regards Rowland -- | Rowland Carson LAA #16532 http://home.clara.net/rowil/aviation/ | 1190 hours building Europa #435 G-ROWI e-mail <rowil@clara.net> Checked by AVG - www.avg.com 07:26:00

    Subject: Rigging/Derigging
    From: "Roland" <schmidtroland@web.de>
    Hi all! I'm interested in buying a Europa XS Trigear. I have the opportunity to keep it at home. Since the factory advertises it as no problem, rigging the aircraft within 5 Minutes and drive home with it, this is really an issue to reduce the running costs. Onother advantage would be the possibility to fill up the tank at the filling station much cheaper and do maintanance at home. Is there anyone of you who rigs his aircraft before any flight? How long does it take you from the trailer in the air and is it inevitable doing this with two persons? Any comments most welcome! Roland Visit - www.EuropaOwners.org
