Actually water tight is easy...the USAF way.



Apply a light coat of proseal the the face of the joggle but not too close to the holes and not the panel. Place a sheet of the "good" plastic wrap like 1 or 2 mil visqueen tightly over the opening, no wrinkles, on top of the proseal AFTER using a hole punch to open up the screw holes, (line the holes up too) install the panel with a bit of petro jelly on each screw snug up the screws and let it sit for a day or two. Remove the panel and using a sharp razor knfe...X-acto works good trim the opening, a single edge razor blade works gfood to get the ozzed bead off the edge of the joggle outside of the skin. I've use this technique to reseal more access panels on the F-16 than I can think about.

John,



I don't mean to nit pick after the fact, but the reason I used

screws was so the hole through the longerons wouldn't have to be

any larger than necessary, hence weaker.  I think mine are #8

screws.  Not necessarily a big deal, but large holes through

a longeron would be something I'd run by vans.  Just posting

here so future builders might benefit from the advice too.

 Last night I put in two pieces of angle running across from one side to 

 the other between the F-1007 and the F-1008 in the tailcone (see 

 picture).  It took a couple of hours to figure out where I wanted it, 

 cut some angle that was extra, get it to the right shape, drill the 

 holes and so on.  It took another couple hours thinking about it, 

 talking about it, etc.  All for 2 angles that may, just may be used to 

 hold a magnetometer or some such thing.  I can't imagine what some of 

 the more complex mods are costing folks in terms of build time! 

  

 However, do this before putting on the top skin of the tailcone, should 

 you even remotely consider hanging an AHRS or some other electronic 

 marvel back there.  Worth doing.  I'm also going to put in extra wires 

 for the rudder trim, for the camera in the VS fairing, and for the two 

 lights in the HS that I turn on when on long final to light up my tail 

 art. 

  

 Finally, at someone's suggestion posted on this list, I downloaded the 

 MS PowerToy to resize pictures.  I use Irfanview to make the photo 

 albums for my website, but for quick and easy, my goodness, get the 

 resize powertoy.  Well worth the couple minutes to download and 

 install.  Just right click any photo you're viewing and select the size 

 and you're done.  One of the better tools.

     Well, one thing for sure, it all depends on which glass unit you

     decide on.  Rob's 3500 has the AHRS in the unit.  The Chelton's have

     both remote, with some placing the magnetometer in the wing, the

     AHRS in various locations.  Etc Etc.  I'm not quite settled on the

     panel, and not quite settled on air conditioning, or a hat shelf, so

     will place a "shelf" aft of the F-1007, just in case, to hold

     whatever, or nothing.  I almost agree to wait for the top skinning,

     but then you have a major component not done.  Others have closed it

     up, made their decisions, crawled around in amazing contorted

     positions to install, and are doing nicely flying from coast to

     coast.  So....   I'll compromise and move on.  I've been on this

     tailcone for an eternity and would like to get off of it.

         My recommendation is to not button down the top three tail skins

         until everything else is completed on the entire aircraft. You

         can start and even perform slow taxi tests with these skins

         off. If you are going to install a remote magnetometer or AHRS

         you can swing the compass and relocate the unit as needed. Keep

         all clecos away from the AHRS as they are iron based.

          

         I have constructed a simple shelf aftmost between the main

         fuselage longeron and the elevator trim servo mechanism. My

         first AHRS in installed in that location was affected by the

         trim servo motor (not running). I scrapped this AHRS for other

         reasons and now tasked to locate the Cross-bow properly.

          

         You can not locate the AHRS just behind the baggage bulkhead no

         matter how high it is installed above the floor. Variable

         magnetic fields from the baggage will affect your heading

         information in uncontrollable ways.

          

         The Cross-bow has a good hard iron calibration routine so my

         next approach will be to locate it far aft and calibrate the

         magnetic interferrence from the trim servo motor out of the

         heading. With this approach there is only one source of

         interferrence.

          

         My suggestion is to delay installation of the three top skins to

         the very end. I will report back after I am satisfied with my

         AHRS installation.

             I'd consider the ability to keep it water tight as well.

             One other way of thinking about these considerations is just

             to not bother

             planning ahead. Just finish the airframe and then install

             the various

             pieces of gear. then you will be sure that it can be

             serviced later and you

             will have figured out the best way to contort yourself to

             get at it for the

             future maintenance.

It's always good to nit pick.  I did think about that, and figured that the

longerons going across might actually be of some stiffening benefit if the

plane wants to hit something solid and those seat belts decide to buckle the

longerons, which they probably would do.  The holes, of course, being firmly

filled with the bolts.  I may be wrong, and thus my entire tailcone is

ruined and unsafe.  Oh, well.  



If I were to do it again, I would use something smaller, even simply pop

rivet a lighter angle.  I had longeron material left over and went ahead

with trying to beef up the structure.
