The fuselage is supplied unassembled (with pre-installed push rods, carbon
and plywood reinforcements) in the Kit - you are supposed to install the
servos, motor and glue the fuselage halves together.
Roughen the contact areas with No. 150-200 sandpaper before applying
glue.
1. Rudder Servo Installation (Fig. 1)
• Locate the right fuselage half. You will find the KAVAN GO-09-sized bay for
the rudder servo in the rear part of the cockpit compartment.
• Prepare the one side arm supplied with the KAVAN GO-09 (or cut a two-
side arm to one side arm). Turn on your transmitter, set the rudder stick and
trim to the centre (neutral). Connect the rudder servo to the appropriate
receiver output (CH4 with the T8FB), plug the ESC’s cable to the throttle
channel (CH3 with the T8FB) and connect the flight pack. Insert the Z-bend
on the end of the elevator push rod into the middle hole in the servo arm
(ca 10 mm from the centre of the arm). Now insert the servo into the servo
bay so the servo output shaft was closer to the nose.
• Now attach the servo arm on the output shaft of the servo - it should be
square to the side of the servo case as much as possible. Secure the servo
arm with the screw supplied with the servo. Glue the servo with drops of
hot melt glue or MS polymer glue over the servo lugs. You can use a me-
dium CA as well, but the hot melt glue or MS polymer glue could be eas-
ily removed without damage to your model if you ever needed to get the
servo out.
2. Motor Mount (Fig. 2+3)
• KAVAN C2814-1400 brushless motor is to be secured to the supplied alu-
minium mount by two M3 setting screws. Check the correct alignment of
the motor mount - the setting screws have to point straight to the access
holes in the side of the fuselage. Glue the motor mount using thick cyano
or MS polymer glue into the slot in the fuselage.
• Please note the motor is offset up and right. This “up thrust“ and “side
thrust” is correct and purely intentional. It compensates the effect of the
propeller stream on the fuselage and tail. Check the correct alignment of
the both two fuselage halves prior gluing the motor mount permanently
into the right fuselage shell.
• Motor direction of rotation check: Connect the motor cables to your ESC
and secure the motor into the motor mount with two M2x6 mm setting
screws. With your radio on check the direction of rotation of your motor
(see fig. 3) as described in the chapter “RC SET INSTALLATION/7. Testing the
Power System” in this manual. Once set correctly, remove the motor from
the motor mount.
3. Elevator Servo installation (Fig. 4)
• Locate the left fuselage half and install the elevator servo in the same way
as you did with the rudder servo. Do not forget to set the servo (CH2 with
the T8FB) into the neutral position with you radio on.
4. Joining the Fuselage Shells (Fig. 5)
• Attach the left and right fuselage shell together. Take care they are cor-
rectly aligned all around. If necessary, sand the contact area flush to create
a neat joint. Once satisfied, apply a bead of thick cyano or MS polymer glue
on the right fuselage shell. (Slow setting glue is required here in order to
give you some time align the fuselage shells correctly - and double check
it). Attach the shells together, check the correct alignment and secure them
with modelling pins or masking tape until the glue sets down. Double
check the fuselage was straight and untwisted; looking along the longitu-
dinal axis of the fuselage, the joint of the fuselage shells must straight. Take
extra care of the good alignment at the wing and tailplane area. This is the
most critical step of the entire assembly - now you can make a straight and
true fuselage that will give you a pleasant plane to fly - or not.
5. Finishing the Fuselage (Fig. 6)
• Check the correct polarity of the canopy lock magnets and cyano them
into the respective recess in the rear side of the cockpit and canopy. Cover
it with a piece of clear sticky tape in the end.
• Cyano (alternatively you can use a thin double sided sticky tape or contact
cement) the plastic reinforcement to the bottom side of the fuselage.
• After the motor (do not forget to apply a blue threadlocker to the setting
screws) and ESC have been installed, secure the plastic servo cover into the
fuselage using drops of hot melt glue, small pieces of hook and loop tape
or small magnets (not supplied in the kit). The point is securing the cover in
place - yet making it removable to access the servos if needed.
• Install the propeller yoke and secure it with two M3x6 mm setting screws
(do not forget to apply a blue threadlocker to the screws). Finally, install the
spinner using two M2x8 mm screws. Be sure the propeller rotates freely;
no matter what the propeller blades may not graze the fuselage. (Fig. 2)
ASSEMBLY
FUSELAGE
WING
1. Releasing the Ailerons
• Deflect the ailerons 10 times up and down carefully in order to make them
move easily.
2. Aileron Servos Installation (Fig. 7)
• You can find moulded servo bays in both two wing halves that fit KAVAN
GO-09 servos or similar. Set the aileron servos to the neutral with your ra-
dio on (in the same way as you did with the elevator and rudder servos).
Attach the one side servo arms so the arms were square to the side of the
servo case as much as possible. Please note you must obtain a mirror image
pair - simply lay both servos down on the table, the output shaft pointing
towards each other and both the servo sides with servo cables pointing in
the same direction. Now attach the servo arms - square to the servo case
side, same on both two servos. Check the operation of aileron servos and
secure the arms with screws supplied with the servos.
• Insert the servos into the servo bays and secure them with drops of hot
melt glue or MS polymer glue over the servo lugs. Connect the supplied
extension cables to the aileron servos; deploy the servo cable (with the
connector put neatly into the bay in the wing) in the aileron servo cable
groove. The end of cable should stick out of the wing by 10 cm (4“) in order
to allow to insert the cable into the fuselage. Apply a strip of clear sticky
tape over the aileron servo cable grooves.
3. Aileron Linkage Installation
• Locate the two short piano wire push rods with pre-formed Z-bend on one
end in the accessories bag. Insert the Z-bend into the outer hole in the ai-
leron servo arm. Insert the other end of the push rod into the push rod
connector in the aileron arm. Repeat for the other wing half.
• (The position of a push rod in holes of a control arm is a way how to ad-
just control throws with a non-computer radio. Moving the push rod closer
to the control surface gives bigger throws whilst moving the push rod to
outer holes reduces the throws. You can also move the position of the push
rod Z-bend on the servo arm - in this case moving the push rod closer to the
centre of the servo arm reduces the throws - and vice versa.)
4. Wing Joiner (Fig. 8)
• Locate the carbon tube wing joiner, insert it into the housing in the fuse-
lage and slide both wing halves onto the joiner.
5. Connecting the aileron servos (Fig. 9)
• A. A radio featuring only one aileron channel (like the T8FB supplied in
the RTF set): Connect both two aileron servos to a Y-cable (not supplied
in the kit). The aileron Y-cable is to be connected to the aileron channel of
your receiver (CH1 in the case of T8FB).
• B: A radio featuring 2 independent aileron servo channels:
Use two 20-
30 ccm extension cables (not supplied in the kit) to connect aileron servos
to your receiver (typically, CH1 and CH5 or CH6 – it depends on the trans-
mitter and its setting – please refer to the instruction manual of your radio).
6. Securing the Wing
• Secure the wing halves by careful tightening the M5x10 mm setting screws
on the bottom side of the wing. (Fig. 10)
7. Aileron Servo Covers (Fig. 7)
• Once the aileron servo operation and aileron linkage has been set and
tested successfully, glue the aileron servo covers in place.
TAIL FEATHERS
1. Releasing the Elevator and Rudder
• Deflect the elevator and rudder 10 times up and down (resp. left and right)
carefully in order to make them move easily.
2. Horizontal Tailplane Installation (Fig. 11+12)
• Glue the horizontal tailplane into the fuselage using medium or thick cy-
ano. Be sure the elevator horn is on the bottom side. Before the glue sets,
check the correct alignment of the horizontal tailplane - it has to be square
to the fin.
3. Elevator and Rudder Linkage (Fig. 13)
• Insert the elevator and rudder push rods into the push rod connector in the
elevator resp. rudder horn.
