I went flying today to test it, and I would say it made one hell of an improvement. It use to take a 1, and, 2, and 3, and then it would pick up the tail. I started my T/O roll, put stick to neutral, and pushed forward, counted 1, and, then it picked up the tail. It actually startled me it went so fast.

Originally we put the VGs about 1 inch in front of the hinge centerline. In reading the STOLspeed instructions they said 4 inches. As and engineer it makes sense. With the stick neutral, it allow the airflow to affix to the top of the airfoil, as you deflect the elevators it should adhere to elevator better as deflected. With the VGs closer to the hinge point, once you deflect from neutral the hinge point will create turbulence. We will see.

In cruise it definitely flys with the tail up. To me it feels definitely tail high. I was really stoke about the change.

You can definitely tell a difference in the responsiveness of the elevator in climb versus decent.

First thing I plan to do is to move the Lower Horizontal Stabilizer VGs further forward. They are currently about 1.5 inches in front of the hinge gap. I want to move them to 4 inches in front of the hinge gap to the leading edge of the VG. Just like I did on the Top.

After I get that done, and tested. I will then add some Gap Seal Tape to the top & Bottom of the Horizontal/Rudder hinge interface.

It’s been a week and 2 days since the surgery, thank goodness the pain, & itching has subsided. The stitches still pull when I lean over, but it is healing nicely.
I’m heading to Travelers Rest next Wednesday to help do some covering. I don’t think I will be capable of doing any heavy lifting.


Many thanks for the many great photos! I'm still going through them, hope you recovery is excellent! What is the red thing on the fuel line?

We cut the Oratex for both the top & bottom of the second wing. Chris had completed squirting some paint. Here are some photos.

Both Chris and I thought working with the Oratex was pretty easy. I had purchase seconds and there’s are some flaws in the material, but all in all two thumbs up. I liked it!


What is the name of the tape you are using there?...and did you use any tape over rivets before putting on Oratex?...I will be using Oratex.

thx

Having used Oratex, I can say, if you have any questions, ask Lars. He will be happy to tell you how to apply and integrate Oratex to your project.

I believe we used polyester tape. I’d have to check what kind it was with Chris (Senior Moment). I just don’t remember. I’ll be talking to Chris tomorrow I also him if we put the Reinforcement on the tops of the ribs. I’m positive we put it on top of the fabric before we riveted it to the wings, because I have a picture of that. You must place a piece of polyester tape over each rib prior to rib lacing or before using whatever means of attachment you decide. Without this tape to reinforce the fabric, the rib lace, screw, etc. will cut right through the fabric and defeat the purpose of this entire step.

By the way if you are getting ready to cover the Aircraft versus using the non-stick sheets with the iron order one of their Teflon self stick sheets to put on the Iron. Chris got one for the last Oratex Planes and said it was a heck of a lot easier that using the sheet under the iron.

Putting Oratex on the bottom of the Flap I believe. Damned I hate that picture you can see my Bald spot. That is what the Beard is about, I’m cultivating for a crop rotation.

Chris Primered the Wings prior to covering. I don’t paint, if I try it will be F’ed up!

Page 9 of my Oratex thread

And no EXTRA tape over the rivets is NEEDED because of the glue - you should put a little extra glue on them before the Oratex tapes go on

I did not use the glue on the rivets but wish that I had. I think that it would have made for a smoother look around each rivet - that is the worst part of the whole thing - ironing around the rivets. If I do another one I will not use rivets. I will rib-stitch. The tail where I used rib stitching was MUCH EASIER to iron the tapes on.

Would you rib stitche @ each rivet location?...or would a guy want to space the rib stitches closer than that ?

The glue is good enough that you prob dont need anything - but not willing to risk my life on glue I would stitch using existing holes.
