Nynja Build Manual 1.4d
e) If the aileron movement feels at all stiff, the holes for the eyebolts on the
trailing edge may need to be eased slightly to achieve good alignment and
thus easy movement. Once satisfied tighten the eyebolts, remembering the
Loctite, and do not over-tighten (as a guide they should still be able to turn
with only moderate finger pressure).
f) Burn a small hole in the fabric at the trailing edge through the 4mm hole at the
rear of the brace.
g) Burn a hole in the same position on the upper surface fabric.
h) Remove the aileron from the wing.
i) Insert a 4mm bolt to hold the angle in position and using the angle as a guide
burn a slot 60mm long on the under surface measured from the centre of the
leading edge spar, Figure 145.
j) Use the long brace from the opposite aileron against the upper surface as a
guide to melt the upper slot.
This slot should be 50mm long measured from the centre of the leading
edge spar.
Figure 145 slot for the aileron horn in the undersurface of the aileron,
k) Put the braces back in their correct positions and secure the trailing edge with
a 4mm bolt passing through the thin sheet aluminium U-piece, the spacer tube
and the lower brace, the sequence shown in Figure 143.
Note that the U-piece edges should be bent up slightly so that the edge
does not cut the fabric over time.
l) Tighten this assembly, and also tighten the 6mm bolt holding the front of the
top and bottom braces.
m) Insert the aileron horn.
If it is a tight fit through the fabric you may have to lengthen the slots a
little.
n) Check the alignment of the rivet holes.
These may have to be gently eased with a 4mm drill or reamer.
o) Insert all rivets, from the horn side, to ensure they all fit, then pull up the rivets.
