Initial Preparation
Laminate 4 layers of 1/16” balsa for the
stabilizer and fin outlines. The finished
laminations should be 1/8” thick.
Laminate 4 layers of 1/16” balsa for the
wing tips. The finished laminations
should be approximately 1/2” thick at
the L.E. and may taper to the T.E.
Laminate two sets of main and rear spar
joiners from 1/16” plywood. Mark the
location of R3 on the joiners.
Laminate the strut mount doublers to the
strut mount F10. Glue a 3/16” diameter
magnet into the hole in one of the
doublers.
Laminate the two 1/16” plywood FWs
together.
Tail Feathers
The center of the stab and base of the fin
are laser cut. Note that the L.E. of the
fin is offset to the left to give some right
rudder, so make sure the center of the
stab is oriented correctly. Frame up the
stab and fin over the plans with 1/8”
thick stock as shown on the plans. Add
1/32” balsa to the L.E. of the stab and
cap strip the structures with 1/32” balsa.
