Covering - Top of the Right Horizontal Stab

I covered what I thought was the bottom right horizontal stab. As you will learn below, I found out this was incorrect. Anyway, I began with the bottom (actually top) and was intending to do a blanket cover with one piece of fabric, starting at the bottom trailing edge, wrapping around the leading edge over to the top trailing edge. The bottom went on without a problem. The top was a different story. Got almost finished but had a good size wrinkle left in the outside rear corner that I tried to shrink out but couldn't. Worked at it for some time and pretty much had it out but it took all the shrink the fabric had to give in doing it. That wasn't acceptable considering I was going to have to final shrink it the next day. So, I cut the top off and finished the leading edge by wrapping the fabric to the inside.

Sunday, I came back to it and cut a new piece of fabric for the top and proceeded. Got it on without too much trouble.

Monday morning I put the final shrink on it and it came out pretty good. Next up, the finishing tapes around the perimeter then on to the next piece.


I received the following email pointing out that I had my Horizonal Stab upside down...

Hi Im building a SS as well and have the flying tail...you can confirm with 
the factory but your stabilizers in your pics are upside down...i put mine 
on the other day and Jack said i had them upside down...the tall part of 
the curve is suppose to go down...to push tail down...opposite of the main 
wing.

Regards,

On par with the rest of the build, I was given incorrect information when I purchased the kit. Yesterday, I did confirm with the factory that Ken was correct, I did have my HS upside down. I wish I would have known before covering as it is now covered backwards with the seams on top. Oh well, the finish tapes will cover them but it is extremely annoying.

I can only wait to see what problems this presents when I go back to mount these in final assembly since they were already leveled, drilled, and flying wires measured, cut and swagged. Now they will have to switch sides.

In any case, many thanks to Ken for sending me a note point this out.
