Finishing the wings tips and gap.




We made the wings in the late 90’s, but we didn’t finish them. So we still need to finish the gap between the stubwing
and the outer wing, and create the wing extension and the wingtips.

First we extended the inner gap between the stub and the wing.

To fill the gap perfectly, we needed the fuselage. So we picked her up, from there she sleeps.

At home we installed the wings and made a nice gap between the stubwing and the outer wing.

Covered the outer part with one layer and shaped the inner side nice round

First add some micro on the foam, so the resin will not be soaked in the foam.

Insert the flox with a wider opened syringe. This will make the corner stronger and it will give a good
connection with the new layer of fabric.

Final result.



Wing extension
IMG_8526
According to the drawing (mod) we need to do an extension on the wing. First we made the straight part and later
we will make the wingtip. First we extended the spars.

IMG_8535
Glued the end rib between the 2 spars and sand it down so the top panel will fit. You can see the wooden
blocks and clamps that will support the foam, while the top, front and aft shelf will be glued.

IMG_8537
Added some weight, so it will stick together under light pressure.

IMG_8555
Added one layer of fabric and at the connections of the spars we made an extra strap of carbon.

Before we closed the lower wing extension we installed a tie town bracket. It will be on the lower side and
upper side. The upper side we probably will use for the wing installation.

After both side’s are covered with fabric, we made the surface smooth with a bit of micro and a bit sanding.
Made the end spar exact 90 degrees on the lower side of the wing.

Wingtip.
We designed the tip by combining a Hoernertip with a small winglet
IMG_8559
This is the start of the wingtip. The wooden plate is a template. So we made both (LH and RH) foam block’s
also 90 degrees faced from the lower side of the wing.

IMG_8581

IMG_8585
Glued both foam blocks at exactly the same position. Now we know both tips will be the same.

First we shaped the front top side. This part will be now in his final shape.

IMG_8602
Turned the wing upside down and start cutting the lower outer corner over the complete length.

IMG_8603
On the wing you see the sanding template

A good view at the sanding tools. Inner and outer radius.

Final result lower side after sanding. The wooden member is a guide for the sanding tool.

With a miller we milled down a 2.3 mm. This will be the end edge of the wingtip. 8 layers of 200gr CF will
fill up the 2.3 mm and will keep the hole edge in shape.

IMG_8635
The red line is the planned line of the (lower) trailing edge of the wing tip.

IMG_8636

IMG_8637
We put fabric on fwd upper part and complete lower part inclusive the CF.

IMG_8661
After curing the lower side we started with the most exiting part……….

IMG_8665
There is a result…..


IMG_8668
Needs only a top layer.

IMG_8672
We put one layer normal fabric and the last part CF.

IMG_8673

IMG_8677
The bolt in the middle of the wing is to pick up the wing from the top. We will probably use a small crane (on the
trailer) to install the wing.
