SBACH 342 Item code: BH174 Instruction Manual
Make certain plane is aligned
accurately per the diagram.
A mis-aligned plane can fly
erraticaliy and cause accidents.
Warning!
Apply epoxy glue
1. Using a modeling knife, cut away the covering
from the fuselage for the stabilizer and remove it.
2. Remove the covering from the stabilizer.
When cutting through the covering to remove it,
cut with only enough pressure to only cut
through the covering it's self. Cutting into the
balsa structure may weaken it. This could lead
to possible failure during flight.
3. Attach the wing to the fuselage as picture.
4. Test the position of the elevator and adjust it as
shown.
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 bottom and to the
top of the stabilizer mounting area and to the
stabilizer mounting platform sides in the fuselage.
Insert the stabilizer in place and re-align. Double
check all of your measurements one more time
before the epoxy cures. Remove any excess epoxy
using a paper towel and rubbing alcohol and hold the
stabilizer in place with T-pins or masking tape.
6. After the epoxy has fully cured, remove the masking
tape or T-pins used to hold the stabilizer in place and
carefully inspect the glue joints. Use more epoxy to fill
in any gaps that were not filled previously and clean
up the excess using a paper towel and rubbing
alcohol.
7. Repeat step 1 - step 2 from the installing aileron for
the installing elevator.
Ensure smooth, non-binding movement
when assembling
