Carefully review how your Electronic Speed Controls (ESC)
work. Most ESC's will not power up a motor until the throt-
tle has been reduced to zero. Avoid both props in case
either or both of the two motors suddenly start to turn.
Step 17.1 Consult your radio manual for instructions about
testing and operating your radio system.
Step 17.2 Pay particular attention to charging your batter-
ies and range testing your system before and after each
flight.
Step 17.3 Check that all controls are working correctly
before and after each flight.
FOR ELECTRIC POWER, YOU WILL NEED TO INSTALL
THE FUSE AND YOUR BATTERY TO TEST THE ESC'S
AND THE MOTORS.
Step 18.1 The CG for your DHC6 Twin Otter is located at
2“ to 2-1/8" (50 - 55 mm) back from the leading edge of the
wing when the wing has been attached to the fuselage as
per illustration 19A.
Step 18.2 For the initial flight, the CG should be located at
2” (50mm) back from the leading edge of the wing when the
wing has been attached to the fuselage.
Step 18.3 The CG is measured with the motor, battery and
all other components installed.
Step 18.4 Set up the CG as it will be when you fly it.
Step 18.5 It is very important to have the CG correct. Flying
your model with the CG too far back will likely lead to loss
of control and a crash. If you discover that after you have
assembled your model and installed your radio, motor and
battery that the CG of your model is incorrect you must
bring the CG to the correct location by doing the following
BEFORE FLYING :
- Move the battery pack fore or aft
- Do not add weight to correct the CG. Move components &
especially your battery pack rather than add weight. Only
add weight as a measure of last resort.
CONFIRM MECHANICAL INTEGRITY
STAGE
19
Step 19.1 Once you have confirmed that the CG is correct,
you should do a thorough review of the entire model before
your first flight. Check everything twice! Every hook up,
every coupling, everything! Do it twice!!
Step 19.2 Before your first flight, have an experienced flyer
review your work. Do not fly your model until it has been
checked out by a third party who knows how to fly and how
to set up a model aircraft. Do not fly alone. Seek experi-
enced help.
Step19.3 Once you have completed your first flight, get in the
habit of checking your model over before and after each flight!
Don’t fly if you find something that is not right!
CONTROL SURFACE THROW SPECIFICATIONS:
The throws are measured at the widest part of the control
surface. Adjust the position of the pushrods at the control
and/or servo horns to control the amount of throw. You may
also use ATV's if you radio has them but the mechanical
linkages should still be set so that theATV's are near 100%
for best servo resolution.

FINAL RC SET- UP
STAGE 15
Before starting the final set-up of the model, switch
on the radio and ensure that all trims are in their
neutral positions. Check that the ailerons, elevator
and rudder are centered. If any adjustments are
needed, do these by uncoupling the relevant clevis
and turning it clockwise to shorten the linkage or
counter - clockwise to lengthen it. Only when each
control surface has been centered mechanically in
this way should you begin adjusting the surface
movement (or throw)
Now confirm that the control surfaces are moving in
the correct direction. Use the servo reversing
switches on your transmitter to reverse the direc-
tion of a servo if necessary. The most popular
transmitter mode (with the throttle on the left, with
ailerons and elevator on the right) is shown here.
INSTALLING THE RECEIVER
STAGE
16
Step16.1 Consult your radio manual for instructions about
hooking up your receiver.
Step16.2 Plan where you are going to put the receiver with
consideration for routing the antenna safely.
Step 16.3 Wrap the receiver securely in foam suitable for
RC equipment and wrap the foam insulated receiver in a
plastic bag or cling wrap.
Step 16.4 Generally in the absence of specific instructions
from the radio manufacturer, it is recommended that the
receiver should be placed where it is least likely to have
impact during a crash. Keep the battery pack and other
heavy loose items ahead of the receiver.

13E- Connect the aileron control rod
between the servo arm and the con-
trol horn
To install the aileron servos into the wing you will need the following items:
- 2 micro servos
- Servo mounting screws and grommets as supplied with the servos
- Servo control arms as supplied with the servos
- Two aileron control rod assemblies supplied with the kit. The assemblies consist of a rod with a clevis screwed onto
both ends
- Low tack masking tape
- 2 aileron control horn assemblies
Ensure Stage 10 has been completed before continuing.
Step 13.1 Turn the wing upside down. Install one servo first, then the second servo.
Step 13.2 Trial fit the aileron servo into the servo mounting cavity. You may have to modify the cavity slightly to provide
clearance for the servo and servo wires.
Step 13.3 Use a hobby knife to modify the cavity as required. Most servos have their output shaft closer to one end than
the other. Mount the servo so that the output shaft is closer to the trailling edge of the wing.
Step 13.4 Screw the servo into place with the screws and grommets supplied. It is important to install the grommets and
screws correctly. See the manual that came with your servos for instructions about your particular servo grommets.
Step 13.5 Fasten the screws down according to the servo manufacturers recommended tightness.
Step 13.6 Repeat steps 13.2 to 13.5 for the second aileron servo.
Adjust the deflection of the control surfaces to match the
specifications on page 12. You can reduce the amount of
throw by doing either or both of the following:
- From the servo end, move the clevis to a hole in the servo
arm that is closer to the servo output shaft.
- From the control horn end, move the control rod/clevis fur-
ther out on the horn (away from the control surface).
Always confirm that the clevis is firmly attached after mak-
ing any adjustment.

FINAL RC SET- UP
STAGE 15
Before starting the final set-up of the model, switch
on the radio and ensure that all trims are in their
neutral positions. Check that the ailerons, elevator
and rudder are centered. If any adjustments are
needed, do these by uncoupling the relevant clevis
and turning it clockwise to shorten the linkage or
counter - clockwise to lengthen it. Only when each
control surface has been centered mechanically in
this way should you begin adjusting the surface
movement (or throw)
Now confirm that the control surfaces are moving in
the correct direction. Use the servo reversing
switches on your transmitter to reverse the direc-
tion of a servo if necessary. The most popular
transmitter mode (with the throttle on the left, with
ailerons and elevator on the right) is shown here.

Step16.2 Plan where you are going to put the receiver with
consideration for routing the antenna safely.
Step 16.3 Wrap the receiver securely in foam suitable for
RC equipment and wrap the foam insulated receiver in a
plastic bag or cling wrap.
Step 16.4 Generally in the absence of specific instructions
from the radio manufacturer, it is recommended that the
receiver should be placed where it is least likely to have
impact during a crash. Keep the battery pack and other
heavy loose items ahead of the receiver.

5J- Insert the horizontal stabilizer into
the slot.
Step 5.2 Mark the outline of the vertical stabilizer onto the horizontal stabilizer
using a non-permanent felt tip marker. See 5D & 5E..
Step 5.3 Now remove the horizontal stabilizer. Using a sharp knife & ruler CARE-
FULLY cut just 1/16 (1.5 mm) inside the marked lines (see 5F) and remove the
covering on both sides of the horizontal stabilizer (see 5G), , making sure you only
press hard enough to cut the covering, not the horizontal stabilizer.
USE CA TO FILL AND REPAIR ANY CUT MARKS IN THE WOOD.
Step 5.4 Apply sufficient 30 minute epoxy to the exposed wood areas on the top
and bottom of the horizontal stabilizer and into the slot of the vertical stabilizer. Use
only 30 minute epoxy. See 5H and 5I
Step 5.5 Insert the horizontal stabilizer in its slot in the vertical stabilizer and re-
check the alignment as in step 5.1. See 5M
Step 5.6 Clean off any excess epoxy with a rag or tissue before it cures. See 5K.
Step 5.7 After the epoxy has completely cured, install the rudder to the vertical
stablizer using the hinges supplied. Glue hinges into place using thin CA. See 5L.

Carefully review how your Electronic Speed Controls (ESC)
work. Most ESC's will not power up a motor until the throt-
tle has been reduced to zero. Avoid both props in case
either or both of the two motors suddenly start to turn.
Step 17.1 Consult your radio manual for instructions about
testing and operating your radio system.
Step 17.2 Pay particular attention to charging your batter-
ies and range testing your system before and after each
flight.
Step 17.3 Check that all controls are working correctly
before and after each flight.
FOR ELECTRIC POWER, YOU WILL NEED TO INSTALL
THE FUSE AND YOUR BATTERY TO TEST THE ESC'S
AND THE MOTORS.
Step 18.1 The CG for your DHC6 Twin Otter is located at
2“ to 2-1/8" (50 - 55 mm) back from the leading edge of the
wing when the wing has been attached to the fuselage as
per illustration 19A.
Step 18.2 For the initial flight, the CG should be located at
2” (50mm) back from the leading edge of the wing when the
wing has been attached to the fuselage.
Step 18.3 The CG is measured with the motor, battery and
all other components installed.
Step 18.4 Set up the CG as it will be when you fly it.
Step 18.5 It is very important to have the CG correct. Flying
your model with the CG too far back will likely lead to loss
of control and a crash. If you discover that after you have
assembled your model and installed your radio, motor and
battery that the CG of your model is incorrect you must
bring the CG to the correct location by doing the following
BEFORE FLYING :
- Move the battery pack fore or aft
- Do not add weight to correct the CG. Move components &
especially your battery pack rather than add weight. Only
add weight as a measure of last resort.
CONFIRM MECHANICAL INTEGRITY
STAGE
19
Step 19.1 Once you have confirmed that the CG is correct,
you should do a thorough review of the entire model before
your first flight. Check everything twice! Every hook up,
every coupling, everything! Do it twice!!
Step 19.2 Before your first flight, have an experienced flyer
review your work. Do not fly your model until it has been
checked out by a third party who knows how to fly and how
to set up a model aircraft. Do not fly alone. Seek experi-
enced help.
Step19.3 Once you have completed your first flight, get in the
habit of checking your model over before and after each flight!
Don’t fly if you find something that is not right!
CONTROL SURFACE THROW SPECIFICATIONS:
The throws are measured at the widest part of the control
surface. Adjust the position of the pushrods at the control
and/or servo horns to control the amount of throw. You may
also use ATV's if you radio has them but the mechanical
linkages should still be set so that theATV's are near 100%
for best servo resolution.
