Instructions
expanding, don’t be shy with the CA so this ensures the spar will not
float.
7. Using a small cup, mix approximately ½ ounces of dark Gorilla glue (PU
glue) with a few drops of water using a Popsicle stick. Mix thoroughly.
8. Pour mixture onto second spar using a Popsicle stick, run back and
forth to ensure thorough distribution of glue, this will fill the gap and
encapsulate the spars making the I beam system complete.
9. Install the bottom rebar spars. The rebar spars are light colored and
textured. Install wing spars into small slits that extend to winglets
area. To do this, place a thick bead of CA into bottom of channel. Drop
in spars and use CA activator (kicker) to lock into place.
10.These spars will overlap the main internals that have been previously
installed, creating an I beam spar system.
11.Let Gorilla glue foam and cure to approximately 75%. Do not disturb
until at 75%. The outer skin of the PU should be slightly sticky and
raised above airplane surface.
12.Use a snap razor to slice off extra glue, following the contour of the
plane surface. If the glue is sticky, wait until it gets to the point that
it does not stick to the knife. If glue hardens too much, it will be
difficult to achieve desired smooth surface.

1. Place wing face up.
2. Install wing I beam spars in same manner as bottom wing spar with
CA glue and accelerator (kicker). Manufacture does not suggest using
Gorilla glue under any spars, as this may cause the spars to float.

1. Using 200 grit sanding block, sand all surfaces over spars.
2. Use light-weight spackle and spreader to fill these areas. This process
is optional for a smoother finish.
3. After spackle is dry sand smooth.
