SST (Sloper Steve Tribute) – Assembly Instructions.
The SST is a slope glider flying ing designed for
Ultrabatics. A thin symmetrical airfoil, light eight and
extra large elevons allo extreme aerobatic flight in even
the lightest lift.
These instructions ill cover the build of both the 30”
version and 48” version. Notes ill be provided
throughout these instructions about the fe differences in
the build.
Recommended Electronics:
It is up to the builder to decide ho light to build this kit.
The instructions are for the recommended build. It is your
option to deviate from this to make it lighter/less durable
or heavier/more durable.
Servos: (2) 9gram. - 48” SST
(2) 2.9gram – 30” SST
Receiver: 4-6 channel
Battery: 1 or 2 cell 600mah lipo – 48” SST
1 cell 360mah lipo – 30” SST
Transmitter: To achieve 90 deg up thro a computer radio
is required. Elevon mixing is also required.
Note: it is preferred that the receiver be able to take
direct 1 or 2 cell battery voltage. If not then you ill need
a voltage regulator/booster as required.
Build options:
The SST can be built to eight bet een 7 and 12oz
depending on ho light you ant it to be verses
durabiltity.
An ultralight build mainly involves using less covering. The
Tiplets are only covered around the perimeter. The ing
leading edge is covered and part of the elevons are
covered. You can use as small of a battery as you ant
and still get the CG correct.
A durable build ould involve covering the hole ing and
tiplets. You can run a bigger battery ith this build up to
about a 2s-700 mah.
Flying has sho n that there is not very much advantage
to getting belo 9oz eight so full covering can be done
ithout much concern.
In either case e recommend using a minimum of a
9gram servo due to the large size of the elevons.
Painting:
The covering is clear once it has been applied so painting
the bare foam orks ell. EPP is solvent resistant so
normal spray can paint like Krylon ill ork great.
Glue:
The recommended construction glue is Beacon Foam-Tac.
It is a clear contact adhesive that remains flexible hen
dry hich orks excellent ith the flexible EPP foam. It
can be used for general construction as ell as for hinging
the control surfaces.
Wing construction:
Glue the t o ing halves together. When the glue is dry,
use straight pins to hold the spar as sho n. The middle of
the spar should be about 7” from the leading edge . The
ends of the spar should be about 2” from the leading
edge.
Cut a slit in the foam near the 0.5 x 3mm carbon spar.
The cut can be made ¼” off of the carbon to make the
cutting easier. Turn the ing over and repeat on the
bottom trying to make sure the spars are lined up. Apply
glue to the cut and press the spar through the glue and
into the cut so it is flush or just belo the surface of the
ing. Straighten the ing so it is flat and let the glue
cure. Once the top side is done repeat on the bottom side.
Cut a slot and glue in a piece of 1.5mm x 6” carbon near
the trailing edge on the bottom.
Check the ing along the leading edge and make sure it is
straight. While the glue on the bottom spar is still et any
bends in the ing can be removed. Once you are happy
that the ing is straight, set it aside for an hour so the
glue ill set completely.
