It was manifest by a burning smell in the cockpit and a loud unusual engine noise but no loss in power or change in engine parameters. I had it rewelded by the local TIG shop. Has this happened to anyone else. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=175678#175678 ________________________________ Message 2 _____________________________________ Time: 05:52:35 AM PST US Subject: Europa-List: CHTs everywhere From: "rampil" I finally completed my cylinder head temp monitoring system so now I have 3 sites of measurement: Regular Rotax VDO probes into the heads of Cylinders 2, 3 going to an analog gauge; Ring-type CHTs installed under the Rotax CHT probes and monitored by my Blue Mountain EFIS, and finally the Lockwood/Rotax coolant temp probe with a Blue Mountain probe going into the EFIS. So far, I have only done cowl-off, static testing but the results are interesting: The coolant temp at 4000 rpm is 20F higher than the Rotax/VDO which is about 20F higher than the ring probes outside the block. These will probably change when cowled and at cruise and climb which I plan to test when I return from SnF. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=175679#175679 ________________________________ Message 3 _____________________________________ Time: 07:00:33 AM PST US From: "Al Stills" Subject: RE: Europa-List: AZ Europa Owners Jim I have a completed tri-gear in Phoenix, would be happy to show to your friend if we can get together.

If you look in the build manual, it seems to say that you don't use the pacers under the ailerons. I didn't and I will need to trim more skin than I want to to get the required up aileron. If I was going to do it again, I'd probably use the spacers under both aileron and flaps. To attach the spacers, we cut several pieces of packating tape, used a yellow hilighter to draw the line on the flaps, dropped the flaps, I then held each depressor in place while my wife put the tape across it to hold it in place. When they were all on, we ran a couple of thicknesses of packtaging tape the length of the flap to hold the spacers in place.

Also, it does not mention it in the manual but I notice that there is a triangular shaped area on the inboard end of the wing that will also be sealed. It is rather small, so may not be a problem, but I'd probably want to put a hole in that rib too for pressure relief. Make sure the MW-4 rod ends are installed on the aileron bellcrank before closing and have at least two other people confirm that you have not left any tools in the wing before closing. You may also want to mix the Araldite a little thicker than usual so it will "stick to your ribs" (bad pun). Last, don't forget to scuff sand both surfaces well. We just used bricks for weights and it all went fine. Let us know how it goes.

Good day All,
 
I have a quick question.......would those people that have already bonded their top wing skins give their opinion as to the build manual using stir sticks as a spacer when bonding on the top skin? Is their thickness the right amount? If I remember correctly, my stir sticks measure about .070" thick.
 
Thanks in advance.

I do not have the Rotax/VDO probes into the block, only ring probes fitted with a bolt into the original probe holes. I found that the ring probes in flight were cooled considerably by the air flowing in under the cowling. I smeared a generous amount of heat resistant (red) Loctite silicone sealant all around the area. This appears to have effectively insulated the rign probes from direct air cooling.

I suspect the same!. After I get back from Lakeland, I will try to rig some sort of insulating surround for the probes. A little fire-stop caulk or hi-temp silicone may be just the ticket as you have done. I'll let you know. Cheers!

And having done it relatively recently, I agree that you do need the spacer under the ailerons too or you won't get enough clearance.
