    I remember what I did now. I wanted any oil that came out to hit the exhaust stack in hopes that some or most of it would burn instead of getting on the belly, so I swiveled the breather tube towards the pilot's left which did that and gave more clearance to the oil filter. I hope this helps.

    Subject: Spot vs. ACR Personal Locator Beacon
    I've been playing with one of these SPOT devices for while now and think a lot of pilots and pilot's wives will want one, at least up here in Canada where getting out of cell coverage is pretty easy to do. First on the 911 issue when you activate the device on the SPOT website you do give them pretty much the same contact info as a PLB (who to contact, alternate phone #, etc). What the SPOT device gives you that no PLB does is the check-in feature where for $100/yr as often as you want you can push an "OK" button the unit sends a text message and email to who ever you wish that looks like this: SPOT Check OK. Unit Number: 0-7356077 Latitude: 50.4384 Longitude: -104.538 Nearest Town from unit Location: Regina, Sask. Canada Distance to the nearest town: 1 Mile Time in GMT the message was sent: 01/18/2008 17:35:09 http://maps.google.com/maps?f=q&hl=en&geocode=&q=50.4384,-104.538&ie=UTF8&z=12&om=1 Great for letting those on the ground know you are alive and well on XC's, ETA's if some is meeting you at an airport, etc. For the $150/year you can have the device sends a position report automatically every 10 min and from the SPOT website (http://findmespot.com) you have a Google Maps app that shows your position reports. Too bad this device only sends position data, the higher end stuff also sends heading, speed, altitude and some even transmit flight plan data pulled from your GPS but I'm hearing rumors of just slightly higher cost devices much like this one targeted directly a GA are in the works.

    You can expect good speed and handling and decent climbing up to 18,000. It will get up to 21,000+ (I have it on good authority) when fairly heavy, but it doesn't like to climb there and doesn't fly very well. You could probably expect to have to drop the flaps to neutral to maintain altitude, and your indicated airspeed would not be too far above stall speed. do not archive Jesse Saint Saint Aviation, Inc. jesse@saintaviation.com Cell: 352-427-0285 Fax: 815-377-3694 On Jan 24, 2008, at 11:33 AM, Rene Felker wrote: > If they go over 18,000=85..need an IFR flight plan.

    From: "jim berry" <jimberry@qwest.net>
    David, The first layer of tape goes on so that the forward edge of the tape matches the forward edge of sheet metal. Position the cowl. The excess material on my untrimmed cowl overlapped the fuselage by less than 2", so the aft edge of the tape was still visible. The second layer of tape goes on top of the first tape so that the aft edges match. The second tape also overlaps the cowling, with the forward edge of the tape corresponding to the forward edge of the sheet metal. Perfect match. Try it and you will like it.

The stick mount has a weld joining two tubes, Have you all worked to get the control stick to go in beyond the weld? Have any of you cut the end of the control stick at an angle to allow the stick to bottom out inside the wd-0011 stick mount? Also were your stick mounts suffiecently out of round so that it was a real battle to get the stick to go into the mount. ( i've already deburred and removed some of the weld slag and now am about to deal with the out of round condition) Thoughts and comments needed. Best regards, Bob Newman TCW Technologies

    Subject: Coax stripping
    Can someone help a newbie with coax stripping? I'm hoping I'm just too tentative (fussy), but I have a traffic system that is exceptionally sensitive to coax antenna length. There are 4 antennae and they all have to have RG400 length of 16 feet and all four need to be matched in length. Two of them are routed more or less irreversibly, so one error in final assembly could be a disaster, or at least quite expensive. My 3-blade coax stripper (H-tools, Taiwan) is adjustable for depth of cut but not for length of insulator exposed. It cuts RG-400 like a charm with very little adjustment or learning required. However... First issue: The cutter leaves 0.32" of braid exposed. That corresponds nicely with the connector manufacturer's specs. Pasternack Enterprises model PE4450 right angle male TNC spec is 0.300" and PE4044 straight male TNC requires 0.325". Good! The cutter leaves 0.16" of insulation exposed. The Pasternack spec is 0.100". Not so good? There is no way to adjust that length. Could it be that the exposed length of insulator is not terribly critical, because Googling coax strippers doesn't show any units that specify the lengths that they cut, or any that allow adjustment of the exposed insulator length, although some, including mine, seem to be adjustable for length of exposed braid? Second issue: Fit of the center conductor into the pin. There's no spec on this, but It seems that 6 or so individual strands need to be clipped to let the conductor slide into the pin. Is this common? Am I missing something about fitting the conductor into the pin? Also, the spec for the exposed center conductor length is 0.100" (PE4044) or 0.125 (PE4450), but it appears that the pin will accept at least 0.180". Hmmm... Any help from the experts in this group is greatly appreciated. John Ackerman 40458 trying to get as much done as possible before installing cabin lid.

    The best advice I can think of is to buy a couple of sacrificial connectors and crimp some scrap and see what you think. I used some TNC connectors by Cambridge, I think, and for me, the stripper worked great and everything went together pretty much with just the right lengths. The connectors and pins were made for RG-400, and every strand fit in the pin just fine. Perhaps the connectors you're using aren't perfect, but I'm not sure at all. But, doing some tests might be a good idea.

    John, Your in the ballpark, there should be just a smidge...(a thousandths or two) showing between the pin bottom flange and the top of the nylon inner insulator. If it is too short the pin will not engage the inner portion of the connector, you will almost hear and feel it click into place as you slide it into the connector. As Tim says sacrafice a piece of coax and a connector and see. Most BNC/TNC connectors come with a detailed measurement of inner conductor, inner insulator and outer insulator measurments. On my stripper, I measured each blade and adjusted them to the given measurements. Mine has a hex screw for each to adjust. It has worked like a charm since the inital setup.

I'm hoping I'm just too tentative (fussy), but I have a traffic system that is exceptionally sensitive to coax antenna length. There are 4 antennae and they all have to have RG400 length of 16 feet and all four need to be matched in length. Two of them are routed more or less irreversibly, so one error in final assembly could be a disaster, or at least quite expensive. My 3-blade coax stripper (H-tools, Taiwan) is adjustable for depth of cut but not for length of insulator exposed. It cuts RG-400 like a charm with very little adjustment or learning required. However... First issue: The cutter leaves 0.32" of braid exposed. That corresponds nicely with the connector manufacturer's specs. Pasternack Enterprises model PE4450 right angle male TNC spec is 0.300" and PE4044 straight male TNC requires 0.325". Good! The cutter leaves 0.16" of insulation exposed. The Pasternack spec is 0.100". Not so good? There is no way to adjust that length. Could it be that the exposed length of insulator is not terribly critical, because Googling coax strippers doesn't show any units that specify the lengths that they cut, or any that allow adjustment of the exposed insulator length, although some, including mine, seem to be adjustable for length of exposed braid? Second issue: Fit of the center conductor into the pin. There's no spec on this, but It seems that 6 or so individual strands need to be clipped to let the conductor slide into the pin. Is this common? Am I missing something about fitting the conductor into the pin? Also, the spec for the exposed center conductor length is 0.100" (PE4044) or 0.125 (PE4450), but it appears that the pin will accept at least 0.180". Hmmm... Any help from the experts in this group is greatly appreciated. John Ackerman 40458 trying to get as much done as possible before installing cabin lid.
