WING ASSEMBLY
□
1. Use a straight edge to align the false leading edge (FLE) with
the plan. Glue a pinning tab to the front of each stand off as
shown in the photo. Secure each tab to the building board
with a couple of crossed pins. Assure that FLE is at 90º to the
building board.
□
2. Assemble W7 and W7-A and W8 and W8-A. Note the correct
orientation of the A components, they should be on the
outside of the servo bay. A good way to avoid problems here
is to assemble both sets at the same time. Just make sure you
assemble two sets that are opposite each other. Then select the
set for the wing half you are working on.
Builders note:
When assembling laser cut components it is important to remember that the accuracy of the laser cut part
may exceed that of the tolerances maintained by the material. This can be caused by milling tolerance
issues, humidity and other factors in the manufacturing processes. When assembling these components
make sure that all parts align exactly with their respective tabs and slots. If they don’t seem to fit, go back
and locate the problem. Do not force the parts. When they are correctly aligned they will practically fall
together.
When assembling notch and tab parts you will be required to dry fit many parts before gluing them.
This is because many of the internal parts require some movement of other parts to get tabs and slots
into position. Do not glue parts until directed to do so. In the event that a part is missed, you may have
to remove the tab to get it into position. Lets build this puppy but put your glue away for now.
□
3. Place the bottom sheer web (SW-B) on the bench with the slots up.
Slide each rib into its appropriate slot. Note that the first full slot will
be for W2.
□
4. Now install the top sheer web (SW-T) onto this assembly until it
will align with SW-B. Hold the top and bottom of the sheer webs in
alignment at the root and tack glue them with a small amount of thin
CA. Now do the same at the tip of the sheer web. You should now
have all ribs except W-1 captive on the sheer web assembly.
□
5. Slide each rib tab into the appropriate notch in the false leading edge
(FLE).
□
6. Install a wing gusset (WG) at the leading edge of rib W3, W7 and
W11. Make sure the ribs are seated in the leading edge and the ribs
are aligned with the gussets.
□
7. Chamfer the edges of the fore and aft wing tip braces (WT-F & WT-
A) so they will seat at the intersection of the sheer web and W12.
□
8. Install the ply wing tip. It will fit into slots in the leading edge and
sheer web tip and tabs will interface with W11.
All ribs have been installed into the bottom
sheer web. Top sheer web is lying on top
of the assembly and is ready to be installed
next.
Pin tabs are used to secure FLE to the building
board.
