Empennage


This blog is called N888PB for a reason.  I’ve reserved N888PB with the FAA as the eventual registration number for my RV-8.  I got to thinking today.  Three “8”s in a row is a mouthful.  In fact if you count it out the entire registration becomes 7 syllables!  (In case you haven’t figured it out, the eights are for the RV model, and the letters are my initials… kind of lame)

But you know what?  I don’t think I care what my N-Number is!  I do care that its easy to spit out on the radio.  Minimum syllables.  With that in mind, I went to the FAA website today in search of the shortest available number measured in syllables.  The shortest I could find was 21W which turns out to be four syllables.  It does roll off the tongue much easier than 888PB. I can imagine saying “Tower, Experimental Two One Whiskey 3 miles east with information bravo.”  Compare that with “Tower, Experimental Eight Eight Eight Papa Bravo 3 miles east with information bravo.”  Yeah, the first one is much less of a mouthful.  Reserving N-Numbers only costs $10 per number per year, so I reserved 21W.  I’m still not sure which one I’ll use, but I’ve got at least a year!  Maybe something shorter will become available… 🙂

Empennage.  The only thing remaining before I begin the wings is for me to roll the leading edges of both elevators.  I’ve been putting it off because it is kind of a pain in the ass.

Wings.  I had hoped, based on the shipping estimate provided by Van’s, that my wings would arrive prior to this long holiday weekend.  Unfortunately, they did not.  Any day now!  I’ll post more as soon as they show up. I did do some minor shop setup over the weekend.  I labeled containers and organized tools and shelving in final preparation for the wings.  Cheers.


Trim Tab 7 (1.0 hr)

Tonight I installed the elevator trim tab and rib-let.  All went well, and I’m happy with the result.  The trim tab will be complete when I install the blind rivets on the end tabs… a quick task.  I am not going to install the trim servo until much later in the build. I still need to roll the elevator leading edges, and then I’ll essentially be done with the empennage for this stage of the build.  The tips will still need to be done, as well as installing the control surfaces and controls but that will all come in good time.

Trim Tab 6 (1.0 hr)

Last night I was going to get done what I wound up doing tonight, but when I arrived in the garage I realized I had quite the mess of tools and very little room to work.  So I cleaned up quickly and called it a night. Tonight I finished match drilling the trim tab hinge.  Here you can see the hinge clamped in place prior to drilling.  After I completed drilling I deburred and cleaned all the parts. All that remains for the trim tab is to rivet and install!20130814-195425.jpg

I decided to give the rattle can self etching primer a try for these small parts.  A time saver for sure, but I’m not particularly a big fan.  The trim tab is easy to pull off and inspect for corrosion so I’m not as concerned about using the time intensive and better AKZO primer.  20130814-195431.jpg
