Instruction Manual

 

5.  When you are sure that everything is

aligned correctly, mix up a generous amount
of 30 minute epoxy. Apply a thin layer to the
top and bottom of the stabilizer mounting area
and to the stabilizer mounting platform sides
in the fuselage. Slide the stabilizer in place and
re-align. Double check all of your measure-
ments one more time before the epoxy cures.
Remove any excess epoxy using a paper
towel and rubbing alcohol and hold the stabi-
lizer in place with T-pins or masking tape.

C/A glue

Epoxy glue.

 

4.  Remove the stabilizer. Using the lines

you just drew as a guide, carefully remove the
covering from between them using a modeling
knife.
          

When cutting through the covering

to remove it, cut with only enough pres-
sure to only cut through the covering it’s
self. Cutting into the balsa structure may
weaken it. This could lead to possible fail-
ure during flight.

Remove covering.
