AILERONS
V-18
The Aileron Tip Ribs 6SV3-3 are installed later after the Fiberglass Wing Tip and End Rib 6SV3-2
have been installed.
26.
The Aileron Ribs are positioned in line with the Rear Bibs to create a continuous rivet line.
REFERENCE
: 6SV3, 6SV4, 6V10
LAYOUT
: Use rib station on the Top Skin 6SV3-5 as a template to mark the Aileron ribs
stations.
a) Mark the I/B angle on the top side of the Aileron skin starting at the I/B end of the
Skin. (38mm along the front edge will set the 11 degree angle, see 6SV3-1 left
middle of the page).
b) From the I/B angle of the Aileron Skin mark an 10mm off-set line: the rivet line for
6V10-31
c) The Aileron Ribs 6V10-3 are parallel with the Root Rib 6V10-31.
CHECK
: The Aileron trailing edge is a straight line. This is easily checked by viewing down
the length of the skin from either end. Remember to check the trailing edge for straightness
frequently during construction.
TRIM
: Cut the top side first, mark the bottom on the same angle as the root of the Main spar to
place the Horn is parallel with the Ribs on the wing center section.
PRE-DRILL
: Since the Rib Flanges are cut on an angle, take extra care to determine the
position of the end-holes to maintain proper edge. Use the Rivet patter of the Root Rib as a
template for the other ribs. Refer to drawing 6V10 for the rivet pitch (2 A4 in the web, 5 A4 in
the top and bottom flange). The rivet layout is:

SUGGESTION
: The Aileron Horn 6V10-2 is installed later to check for a
Radius = 100 see
6V10.
27.
Rivet the Aileron Root Rib 6V10-31 (t=.025) flush with the I/O end of the Skin 6SV3-1
SUPPORT
: To make the trailing edge straight work with the Skin on two parallel boards,
support the trailing edge along a straight reference (such as two 8 ft. steel 4” “I” beams). Raise
one end of the beam 12mm off the table to set the Aileron Twist.
28.
Rivet the Aileron Ribs 6V10-1. Start with the rear flange followed by the top flange. The
Aileron twist (wash-out) is 12mm up at the O/B tip as view on the finished aircraft.
REFERENCE
: 6SV3 Middle left side of page.
RIVET
: a) The front rivet line through the Aileron flange will set the Aileron twist.
b) Plan for a rivet at the intersection with the Rib rivet line.
29.
Cleco the Aileron to the wing.

E: 6V10
CLAMP
: The Aileron trailing edge is parallel with the Rear Zee leaving 20mm between the
Rear Zee and the Aileron web.
CHECK
: Distance from the Aileron trailing edge to the aft edge of the top skin is
approximately 215mm (measured along the rib centerlines).
