TIP: How to cut carbon spars. Wrap masking tape around
carbon spar and mark cut position. Use rotary tool or X-
ACTO fine saw to cut the spar.
Work outside or in room with good ventilation. Use
breathing mask to avoid inhaling carbon dust! After cutting
wipe out carbon dust from the spars using wet tissue.
TIP: Carbon wing joiner tubes on the fuselage
should fit into spars in the wing. Sometimes the
fit is too tight or you cannot insert joiner tubes
into wing spars at all. You can use drill and wet
sandpaper to make joiner tubes thinner. Use
breathing mask to avoid inhaling carbon dust!
Remove support legs from all parts. Also sand all sharp edges and
printing imperfections to avoid covering foil damage.
