Please be aware that this aeroplane is not a toy and if assembled or used incorrectly it
is capable of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU
ASSUME ALL RISK & RESPONSIBILITY.
If you are inexperienced with basic R/C flight we strongly recommend you contact your R/C

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 cou-
ple of jars or bowls handy to hold the small
parts after you open the bag.
Please trial fit all the parts. Make sure you
havethe correctpartsandthatthey fitand are
alignedproperly beforegluing!This willassure
proper assembly. SONIC ARF is hand made
from natural materials, every plane is unique
andminor adjustmentsmayhavetobe made.
However, you should find the fit 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 follow-
ing:paintthinner,C/Aglueaccelerator,C/Aglue
debonderandacetone. Donotletthesechemi-

 3. Turn the airplane upside down. Place
your fingers on the masking tape and care-
fully lift the plane .
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located 60mm back from the
leadingedge.Thisisthebalancepointat which
yourmodel shouldbalancefor yourfirstflights.
Later, you may wish to experiment by shifting
the balance up to 10mm forward or back to
change the flying characteristics. Moving the
balance forward may improve the smooth-
ness and arrow- like tracking, but it may then
require more speed for take off and make it
moredifficult toslow downfor landing.Moving
the balance aft makes the model more agile
with a lighter and snappier ”feel”. In any case,
please start at the location we recommend .
With the wing attached to the fuselage, all
parts of the model installed ( ready to fly), and
empty fuel tanks, hold the model at the
marked balance point with the stabilizer level.
Lift the model. If the tail drops when you
lift,themodel is“tailheavy” andyou must add
weigh*tothe nose.Ifthenosedrops,itis “nose
heavy” and you must add weight* to the tail to
balance.

1) It is critical that your airplane be bal-
anced correctly. Improper balance will cause
your plane to lose control and crash.

2) Mount the wing to the fuselage. Using a
couple of pieces of masking tape, place them
on the top side of the wing 60 mm back from
the leading edge, at the fuselage sides.

BALANCING.
4 x 30mm

SONIC- Item code: BH86.INSTRUCTION MANUAL

*Ifpossible,first attemptto balancethe model
by changing the position of the receiver bat-
tery and receiver. If you are unable to obtain
good balance by doing so, then it will be nec-
essary to add weight to the nose or tail to
achieve the proper balance point.

1) We highly recommend setting up a
plane using the control throws listed.
 2) The control throws should be meas-
ured at the widest point of each control sur-
face.
 3) Check to be sure the control surfaces
move in the correct directions.
CONTROL THROWS.
Ailerons : 12 mm up 12 mm down
Elevator : 10 mm up 10 mm down

1) Completely charge your transmitter and
receiver batteries before your first day of fly-
ing.
 2) Check every bolt and every glue joint in
your plane to ensure that everything is tight
and well bonded.
 3) Double check the balance of the
airplane.
 4) Check the control surface.
 5) Check the receiver antenna . It should
be fully extended and not coiled up inside the
fuselage.
 6) Properly balance the propeller.
PRE-FLIGHT CHECK.
We wish you many safe and enjoyable
flights with your SONIC.
