“EPOFLEXY” is a ver
y tough and durable material perfect for the manufacture of model aircraft. When
using screwed fixings with “EPOFLEXY” components it is important to tighten the screws sufficiently to
provide a firm fixing.
Excess tightening could result in the foam material becoming compressed, possibly damaging or
distorting the part. Take care to ensure that all screws are tightened sufficiently to provide a firm fixing,
but do-not over tighten. We recommend that all fixings are checked regularly for security and safety
purposes.

Overview
Thank-you for purchasing this MAX-THRUST RIOT radio controlled model aircraft. The RIOT offers a
stunning combination of terrific looks and sensational flight performance. Manufactured from
“EPOFLEXY” it is extremely robust, however, in the event of a “less than perfect” arrival, we supply a
range of spares to get you flying again in the shortest time. It is capable of a wide range of amazing
aerobatic manoeuvres to thrill the experienced pilot, but with reduced control throws it provides a
solid and predictable flight performance, perfect for the sports flyer.
We are certain you will enjoy your new model, please take the time to read this manual thoroughly and
understand its contents completely prior to commencing assembly.

Assembly Instructions
1. Undercarriage.
Fix the undercarriage in position
with the four 2.6 x 12mm self-
tapping screws as shown, (image A).
Note: The undercarriage legs are
angled towards the front of the
fuselage.
2. Horizontal Tail
-
Plane.
Slide the horizontal tail
-
plane into
the fuselage slot as shown, (image
B). Make certain that the holes in
the tail-plane line-up with the
corresponding fuselage holes.
If desired, a small amount of foam
glue can be used for maximum
security.

B
Install the vertical fin and rudder
assembly into the slot in the
fuselage. Please make certain
that the tail-wheel control wire is
located correctly in the rudder
slot as shown, (image C).
If desired, a small amount of
foam glue can be used for
maximum se
curity.

4. Tail
-
Plane Fixing.
Fix the horizontal tail
-
plane and
vertical fin in position with the two
2.6 x 35mm screws provided, (image
D). The screws must be tightened
sufficiently to securely fix the parts
in position, however be careful not
to over-tighten the screws.

5. Tail Control Horns.
Connect the rudder and elevator
snap-links to their respective control
horns as shown in images E & F.
Minor adjustment to obtain perfect
neutral positions of the control
surfaces can be achieved by rotating
the plastic link on the threaded
portion of the control push-rod.
Make certain the plastic link is
securely “snapped” closed when
connected to the control horn.

Plastic Collar
Locate the 500mm
aluminium wing
joining spar and slide into the round
aperture of one wing panel up to the
centre locating collar. Locate the small
plywood wing locking plate and insert
into the rectangular aperture behind
the main wing spar, (image G). Slide the
remaining wing panel onto the exposed
portion of the aluminium spar. The
plywood locking plate will ensure
perfect alignment of the two wing
halves. Be certain that all wires are
routed correctly via the moulded slots
and do not foul the joint between the
wing roots. If desired, a small amount of
foam glue can be used for maximum
security.
6. Wing Assembly.
G
Connect the two black aileron servo
plugs from the wing to the “Y” lead
as shown, (image H). The remaining
plug from the “Y” connector should
be plugged into socket “A” of the
pre-installed circuit board located in
the fuselage, (image I). Please pay
particular attention to the polarity of
this connection as shown in the
diagram.
H
I
Socket “A”
The two remaining white plugs from
the wing are for the model’s built-in
LED lighting system and should be
connected to the corresponding
sockets on the circuit board, (image
I). You will note these plugs are
polarity protected to prevent
incorrect connection.

Note:
The plastic connectors are angled for
the wing camber.

Insert the front and rear plastic
connectors into the wing, (image J).
They are angled to provide a perfect
fit. Make certain you have them
located correctly! The wing can now
be trial-fixed in position onto the
fuselage using the 3 x M4 x 50mm
screws provided.
7. Wing Fixings.
8. Propeller & Spinner.
Fit the propeller and spinner to
the motor as shown, (images K &
L).
Note: It is essential that the
propeller is securely fixed.
Failure to do so could result in
serious injury.

9. Receiver Installation.
© Copyright Century UK Limited 2012 www.centuryuk.com
Connect the speed controller to the throttle channel of your receiver, (not included). This wire is easily
identified, it is the only one that is routed from the front of the model.
Connect the rudder and elevator servos to the corresponding channel outputs of the receiver and
connect the one remaining lead from the circuit board to the aileron channel output. There is a
moulded recess in this compartment which is sufficient to accommodate most popular 2.4GHz
receivers; however there is ample room elsewhere to locate yours if it does not.
We recommend that it should be securely positioned with self-adhesive “Velcro”.
You must adhere to the receiver manufacturer recommendations regarding positioning and aerial
routing.
10. Battery Installation.
The battery compartment is accessed by gently s ueezing the two ra
ised white tags and lifting the
rear of the front hinged cover, (image M). Your flight battery, (not-included) can easily be installed and
connected to the factory fitted “T” style connector, (image N). Make certain the battery and cover are
both secure before flight.

11. Control Surfaces.
Check that all control surfaces are centred and responding correctly to transmitter inputs.
Adjustments can be made to control surface centres by carefully rotating the plastic control horns on
the threaded portion of the metal control rods. Use the servo reversing function on your transmitter
for any control that is not responding in the correct sense to control inputs. Make certain that all
plastic links are securely “snapped” closed and that all control surface hinges are secure. Use a small
amount of foam glue if any hinges are not firmly attached.
12. Propeller Rotation.
Double
-
check that the propell
er is securely fixed and it is
rotating in the correct direction, (image O).

1 . Centre of Gravity.
P
It is vital that you check that the
centre of gravity is correct. Failure
to do so could result in a complete
loss of control. We recommend the
balance point of the model,
complete with battery, should be
75 -90mm back from the leading
edge of the wing for initial flights,
(image P). Very experienced pilots
may wish to move the balance
point further back after initial flight
testing.
14. Control Surface Deflecti
ons.
We make the following recommendations for control surface deflections. Experienced pilots may
wish to increase these movements after initial flight testing.
Ailerons: 10mm each way.
Elevator: 10mm each way.
Rudder: 12mm each way.
Mark Tilbury: Designer.
We hope you enjoy many happy and safe flights with
your new Max-Thrust RIOT model aircraft.
