WARRANTY
Read this disclaimer carefully before using this product.
Please strictly follow the instruction manual to assemble
and use this.
In that Black Horse Model has no control over the nal
assembly or material used for nal assembly, Black Horse
Model is not responsible for loss of use , or other
incidental or consequential damages.
Furthermore, Black Horse Model cannot be held liable for

DISCLAIMER
Please trial t all the parts. Make sure you have the
correct parts and that they t and are aligned properly
before gluing! This will assure proper assembly. This kit is
hand made from natural materials, every plane is unique
and minor adjustments may have to be made. However,
you should nd the t superior and assembly simple.
The painted and plastic parts used in this kit are fuel
proof. However, they are not tolerant of many harsh
chemicals including the following: paint thinner, C/A glue
accelerator, C/A glue debonder and acetone. Do not let
these chemicals come in contact with the colors on the
covering and the plastic parts.
Some parts included in this kit such as the cowl or
wheel pants are made of berglass, the bers of which
may cause eye, skin and respiratory tract irritation. Never
blow into a part to remove berglass dust, as the dust will
blow back into your eyes. Always wear safety goggles, a
particle mask and rubber gloves when grinding, drilling
and sanding berglass parts. Vacuum the parts and the
work area thoroughly after working with berglass parts.
IMPORTANT BUILDING NOTES
To avoid scratching your new airplane, do not unwrap
the pieces until they are needed for assembly. Cover your
workbench with an old towel or brown paper, both to
protect the aircraft and to protect the table. Keep a
couple of jars or bowls handy to hold the small parts after
you open the bag.
SUGGESTION
ALWAYS operate in open areas, away from factories,
hospitals, schools, buildings and houses etc.
NEVER y your aircraft close to people or built up areas.
NEVER y near power lines, aerials or other dangerous
areas including airports, motorways etc.
NEVER y in wet conditions or on windy or stormy days.
ALWAYS adjust the engine from behind the propeller, and
do not allow any part of your body to be in line with the
propeller.
THE PROPELLER IS DANGEROUS Keep ngers, clothing
(ties, shirt sleeves, scarves) or any other loose objects that
could be caught or drawn in, away from the propeller.
Take care at ALL times.
NEVER use damaged or deformed propellers or spinners.
KEEP all onlookers (especially small children and animals)
well back from the area of operation. This is a ying
aircraft, which will cause serious injury in case of impact
with a person or animal.
DO NOT dispose of empty fuel containers on a re, this
can lead to an explosion.

of the 2mm x 180mm threaded wires.
2) Attach the clevis to the outer hole in the control
horn. Install a silicone tube on the clevis.
3) Locate one nylon servo arm, and using wire
cutters, remove all but one of the arms. Using a
2mm drill bit, enlarge the third hole out from the
center of the arm to accommodate the aileron
pushrod wire.
4) Plug the aileron servo into the receiver and
center the servo. Install the servo arm onto the
servo. The servo arm should be perpendicular to
the servo and point toward the middle of the wing.
5) Center the aileron and hold it in place using a
couple of pieces of masking tape.
6) With the aileron and aileron servo centered,
carefully place a mark on the aileron pushrod wire
where it crosses the hole in the servo arm.
7) Using pliers, carefully make a 90 degree bend
down at the mark made. Cut off the excess wire,
leaving about 6mm beyond the bend
8) Insert the 90 degree bend down through the
hole in the servo arm. Install one nylon snap
keeper over the wire to secure it to the arm. Install
the servo arm retaining screw and remove the
masking tape from the aileron
9) Repeat step # 4 - # 8 to install the second
aileron linkage. After both linkages are completed,

1) Hinges for Elevator are glued the same way as the
aileron before (see page 8).
2) Draw a center line onto the horizontal stabilizer
3) Using a modeling knife, cut away the covering
from the fuselage for the stabilizer and remove it.
7) 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. Slide 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.
8) 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.
4) Check the fit of the horizontal stabilizer in its slot.
Make sure the horizontal stabilizer is square and
centered to the fuselage by taking measurements,
but don't glue anything yet.
5) With the horizontal stabilizer correctly aligned.
Apply a thin CA layer to the top and bottom of the
stabilizer in the fuselage
6) 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 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.
