E-flite Byp Yak 3D ARF - Manual (Page 13)

Note: You may want to locate a thin piece
of Depron or other foam for the next section.
A thin board will work too. This is necessary
to keep the wing as flat as possible to keep
from inducing any twist in the wing, which will
greatly affect the performance of your Byp Yak.
 6. Glue the strut reinforcement disks to the bottom
of the top and bottom wings. The positions have
been marked at the factory. The slots in the disks
will run parallel to the spars.
 7. Once the CA has fully cured from Step 6, slide
a hobby knife into each of the reinforcements to
make a thin slot. Do not cut an official slot; just
slip the knife in and out.
