AILERON SAILS

STEP

INSTRUCTIONS

for Assembly, for Disassembly reverse the order!

PART NO.

STAGE CERT.

Sprinkle generous amounts of baby powder into fabric

aileron port

and on aileron frame. Pull sail onto frame until just snug. (Patches are sewn
on top side of sail). Twist sail until inside seam is on bottom side of frame
and return seam to centre of trailing edge tube.  (All of seam should be on
bottom side. If it flips you will have bumps in sail).  Slide frame into sail as
far as possible. Block inboard end of aileron against something (e.g. a wall).
Put on rubber gloves.  Beginning at outboard end, work small amount of
fabric at a time to inboard.  (This is a long process generally requiring an
hour to pull sail on completely.  Work in small increments.  When you get
frustrated, remember, the tighter the fabric, the crisper the roll control).  With
only the gap cover on aileron inboard fabric turned inside out, slide onto
inboard aileron frame. Burn small slits in the pockets of aileron fabric
inboard and outboard on trailing edge side.  Slide

aileron tension bars

into pockets. Burn slits for tie wraps. (10 tie wraps total: 1 hole top and
bottom, evenly spaced, aft of aileron main spar: 1 hole topside near leading
edge: 1 hole bottom side near ail main spar). Insert tie wraps through inside
of holes around tension bar in ail outboard then around tension bar in aileron
inboard from outside to inside. Fasten tie wraps and pull snug. (This puts tie
wrap connection on inside so you will be pulling with sail rather than against
it). Tighten tie wraps.

Put rubber gloves back on. Go to tip of aileron and work out wrinkles.
(Rotate tie wraps so that connection is to outboard so you do not run out of
space while tightening). Pull tie wraps tight. Work out wrinkles, rotate tie
wraps, tighten. Repeat until gap closes to 1”. To close gap cover, roll fabric
down, side to side, until right side out (if gap cover stops when it reaches
outboard fabric, trim outboard fabric at leading and trailing edges with a hot
knife).

Stop now if you intend to paint.
