The balsa wing ribs are very fragile until the wing is fully
constructed. When sliding them onto the spar web, hold
them on either side of the slot, and do not force them!
Do NOT attempt to remove them once inserted, the
balsa WILL snap!
The wing ribs are slid onto the spar
web with both upside-down. Be
careful to ensure the spar web is
fully inserted into the slot on each
rib.

Turn the ribs and spar web over. Pin
the balsa ribs to the board by the
rear tab, using the False LE and TE
to keep them all square. Make sure
they are flat to the board.
Once pinned, glue the False LE, TE,
Bolt plate, spar and both R5 ribs
into position. Make sure that the
spar is glued to each wing rib as
well as to the spar web along its
entire length.
Make sure you glue the bolt
plate before the TE!
