Overvie
Thank-you for purchasing this MAX-THRUST Ryan STA radio controlled model aircraft.
The Ryan STA 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 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.

Please %ote:
“EPOFLEXY” is a very 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.
1. Hinge check
heck that all control surface hinges are firmly secured. If required they can be cut and the
'live-hinges' supplied can be fitted.
2. Horizontal Tail Plane
Fix the elevator control horn in the moulded recess
as shown using two M2 x 15mm screws, (image 1).
Make certain that the plastic horn is fitted to the
correct side, with the plastic reinforcement plate
fixed in the moulded recess on the top side of the
elevator.
1
Using a light grade abrasive paper, lightly abrade the painted mating surfaces where the
horizontal tail plane joins the fuselage. This provides a good key for the adhesive. (image 2).
Glue the horizontal tail plane in position using the supplied adhesive. Secure in position using
the M2 x 40mm screws, (image 3). Use the adhesive sparingly towards the edges of the parts
to be glued and immediately wipe any excess from the joint.

3. Vertical Fin & Rudder
Fix the plastic rudder control horn in the moulded recess using two M1 x 20mm screws.
Make certain that the plastic horn is fitted to the correct side, with the reinforcement plate
fixed in position on the opposite side of the rudder. Using a light grade abrasive paper, lightly
abrade the painted lower surface of the rudder and using the supplied epoxy. Fit the tail wheel
to the rudder (image 4). Lightly abrade the top of the mating surfaces of the rudder and
horizontal tail plane to provide a good key for the adhesive (image 5).
Building Tip: Fit the fin and rudder with a 3mm offset to the right for the perfect trim
position.

Apply adhesive sparingly to the mating surface of the
horizontal tail plane and push the fin assembly into
position. Remove any excess adhesive immediately.
Secure in place using an M2 x 40mm screw at the
front mounting point and an M2 x 30mm screw at the
rear mounting point via the fixing holes positioned
underneath the fuselage, (image 7)
4. Fuselage Control Rods
entre the elevator and rudder servos. onnect the
elevator and rudder plastic links to their control
horns. It is recommended to fit the elevator pushrod
to the inner most hole on the elevator servo horn,
Make certain that the control surfaces are in their
neutral positions and that the plastic links are
“snapped” closed, (image 8). Any minor adjustments
to the neutral positions of the control surfaces can be
made by rotating the plastic link on the threaded
8 portion of the control rod.
Building Tip: The control horns should be fitted to
the outer most hole in the clevices.
5. Wing Assembly
First fix the undercarriage, these are handed. The
central rigging mounts should be on the inner edge,
leaving the rearward rigging mounts on the outer
edges (image 9).The undercarriage should be fixed in
position using the screws supplied in the pack.
Once the undercarriage is in place, the main wing can
be fitted. The wing fits in leading edge first, with the
tongue on the wing slotting into the fuselage. Make
sure the aileron servo connections are slotted through
the hole in the underside of the fuselage, otherwise
the wing will not seat properly. The trailing edge of
the wing is fixed in position using the two M2 x
30mm screws (image 10).

Now the wing is fitted, the cabane struts can be fitted
from the topside of the wing to the cockpit using the
screw pack supplied with the them (image 11).
Once the main build has been completed, you may
wish to fit the wire rigging. The rigging is purely
cosmetic and won't alter the flight characteristics of the
model, but does enhance the scale appearance.
There are two different springs used in the rigging
system, springs with hooks at both ends, and springs
with one hook and a closed loop. The closed loop
springs fit to the underside of the wing, and are
screwed down using the screws provided in the
spring pack. (image 12)
12
The springs used on the outside of the undercarriage
legs are hooked at both ends, once these are in place
the wire can be fitted. The main wing uses 1x 210mm
and 1x 190mm wire on each outer edge. The centre of
the fuselage and undercarriage use 4x closed loop
springs, all screwed to the fuselage, 4x open hook
springs hooked to the undercarriage itself and 4x
55mm rig wires. (image 13) 13
The topside of the wing uses open hook springs on all
fittings and the screws provided in the spring pack.
Each side of the wing uses 1x 250mm wire and 1x
270mm wire (image 14). The rudder uses 2x open
hook springs on each side, with 2x 105mm rig wires.
14
Building Tip: Once the rigging wires are fitted, the open ends of the springs should be
clamped shut using long nose pliers to ensure the rigging remains firmly fixed in place.
6. Receiver installation.
%ote: We only recommend the use of 2.4GHz radio equipment with this model and make the
following recommendations for receiver location and mounting. These must be followed in
conjunction with the instructions supplied by your receiver manufacturer.
onnect the aileron (marked H1), the rudder (marked H4) and elevator (marked H2) to
the corresponding outputs on your receiver. Locate the lead from the ES , the lead marked 3
is the throttle control and should be connected to the corresponding output on your receiver.

Please double check that all plugs are connected to the correct outputs on your receiver and
that all leads are routed in a neat and tidy manner.
Mount the receiver inside the fuselage, using your choice
of double sided self-adhesive or “Velcro” tape. The
receiver should be fixed inside the fuselage securely
where it will not foul any moving parts (image 15).
7. Final Assembly
Test all servo connections, and make sure that all control surfaces are operating correctly.
Once you are happy that everything is working, it is time to fit the propeller.
Fit the backplate of the spinner onto the motor shaft,
the backplate is keyed to match the motor bell, once
this is positioned correctly, the two bladed propeller
can be fitted onto the shaft and secured using the lock
nut provided. When the propeller is secured, the
spinner should be fitted using the two small fixing
screws provided. Although not specifically required,
some pilots may wish to balance the propeller for
optimum performance (image 16).

8. Battery Installation
Your flight battery, (not included) needs to be firmly secured in the battery compartment to
prevent it from moving in flight. The flight battery needs to be fitted as far forward as
possible to achieve the correct entre of Gravity. Many pilots have their own favoured
method of securing the battery, so we have left this up to you.
9. Final Checks
Double check that all fixings and fasteners used on the model are secure, including snap
links, servos screws, wheel retaining screws etc. heck that all control surfaces are moving in
the correct direction in relation to control inputs from your transmitter.
We recommend the following control throws for initial flights, however these can be adjusted
to suit your personal preference after flight testing has been completed.
Elevator: 5mm deflection each way.
Ailerons: 5mm deflection each way.
Rudder: 10mm deflection each way.
The centre of gravity of your Ryan STA is 45mm
back from the furthest forward point of the wing.
Using the recommended 1350mAh flight battery,
this centre of gravity should be easily achieved. If
you choose to use a lighter battery it will be
necessary to additional ballast to the model in
order to achieve the correct centre of gravity.
