2. Glue the interplane struts to the bottom wings using

thin foam-safe CA. Use a 90° builder’s square or the
template provided in the back of this manual to properly align
the interplane struts vertically. Note: The front edge of the
interplane struts has less curvature than the aft edge.

3. Apply thin foam-safe CA to the tabs on the interplane

struts and the center cabane strut. Install the top wing.

Link the Ailerons

1. Locate four 1 x 145mm carbon pushrods, eight 1 x 30mm

Z-bends, and eight 25mm pieces of heat shrink tubing.
Assemble four aileron link rods as shown in the sketch
above so that they measure 2-1/8" [156mm] from Z-bend
center to Z-bend center. See the Expert Tip below on how
to assemble pushrods.

How to Assemble Pushrods

To join a wire Z-bend to a 1mm carbon pushrod, fi rst slide
a piece of heat shrink tubing onto the carbon rod. Next,
place the wire Z-bend alongside of the carbon rod. Slide
the heat shrink tubing over the joint and heat it. If you
are working near foam, use a hot soldering iron to shrink
the heat shrink tubing. Run the tip along the sides of the
tubing, applying heat all around the heat shrink tubing.
Check to see that the length of the pushrod is still correct.
If you’re careful, you can reposition the Z-bend after the
heat shrink tubing is completely shrunk, but it’s good
to check it before you’ve completely shrunk the tubing.
When you’re satisfi ed, apply one drop of thin CA to the
end of the heat shrink tubing that is farthest away from
the Z-bend. Be careful not to allow the CA to wick into the
Z-bend if the Z-bend is attached to a control horn.
