Please Note:

“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.

2. Horizontal Tail PlaneUsing a sharp knife, remove the decal covering the recess in the elevator, (image 2). Fix the elevator control horn in the moulded recess as shown using four M2 x 15mm screws, (image 3). Make certain that the plastic horn is fixed to the correct side of the elevator with the plastic reinforcement plate fixed in the moulded recess on the top side of the elevator. Tighten the screws sufficiently to secure the horn firmly in place.

2

Temporarily fix the horizontal tail plane in position on the fuselage using the two M3 x 45mm screws, (image 4). Make certain that the horizontal stabilizer is positioned squarely on the fuselage (the fin slot in the horizontal tail plane should line up perfectly with the aperture below in the fuselage) then use a pen to lightly mark the position of the fuselage on the underside of the tail plane(image 5).

3 4

Remove the tail plane from the fuselage. Using a light grade abrasive paper, lightly abrade the painted mating surfaces to provide a good key for the adhesive, (image 6). Using the adhesive supplied, glue the horizontal tail plane in position, (image 7) and fix firmly in place with the two M3 x 45mm screws, (image 4). Use the adhesive sparingly towards the edges of the parts to be glued and immediately wipe any excess from the joint.

3. Vertical Fin and RudderUsing a sharp knife, remove the decal covering the recess moulded in the base of the rudder, (image 8). Slide the plastic tail wheel steering holder into the moulded recess on the rudder. Position one plastic control horn over the tail wheel steering holder, align the holes and fix with 2 of M2 x 10 screws positioned diagonally as shown, (image 9). Repeat the process for the second rudder control horn, using fixing screws in the two remaining holes. 8

Lightly abrade the painted areas where the vertical fin meets the horizontal tail plane to provide a good key for the adhesive, (image 10). Apply adhesive sparingly to the mating areas, (image 11) then push the fin and rudder assembly into position. Remove any excess adhesive immediately, then secure the assembly in position using two M3 x 60mm screws, (image 12) via the two holes positioned underneath the fuselage .

4. Tail WheelConnect the tail wheel horns to the wheel holder control horns using the two 45mm long Z-Bend rods, (image 13). Fix the metal tail wheel bar in position on the fuselage using the 2 of M2.5 x 12 self- tapping screws, (image 14). Centre the rudder and elevator servos; connect the snap link from the elevator and rudder push-rods to their respective control horns. Minor adjustments should be made so the control surfaces are in the neutral position by turning the plastic links on the threaded metal control rods. Ensure the plastic links are “snapped” in the closed position, (image 14).

5. Wing AssemblyStarting with the right wing panel, use a sharp knife to remove the decal covering the control horn recesses moulded into the aileron, (image 15).Using two M2 x 15mm screws, fix the aileron control horn and its plastic reinforcement plate in position. When fitted diagonally as shown in the image, (image 16), it is not necessary to use more than two screws. Centre the aileron servo, connect the aileron servo to the control horn with the supplied control rod. Minor adjustments 15should be made so the control surface is in the neutralposition by turning the plastic link on the threaded metal control rod, (image 17). Ensure the plastic link is “snapped” in the closed position. Repeat the process for the left wing panel.

Locate the fibreglass wing spar and slide into the round aperture in the right wing panel, (image 18). Slide the other end of the wing spar through both round holes located in the wing seat area of the fuselage. Then slide the left wing panel into position on the spar, (image 19). Make certain that you pass the aileron control leads through the square holes located immediately behind the spar and that they do not get trapped in the process of fitting the wing to the fuselage. Secure the wing in position using the

16 two M3x 50 screws, (image 20).

Receiver Installation

Note: 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.

Connect the two aileron control leads via the supplied “Y” type lead and the rudder and elevator servos to your receiver, (image 21). Then plug the ESC lead, (labelled 3) into the Throttle channel of your receiver. The other lead labelled 6 is for the UBEC system and should be plugged into a spare channel on your receiver, (image 22). Double check you have installed the correct plugs into the corresponding channel outputs on your receiver. We recommend the receiver is fixed in position using good quality double- 21sided or self-adhesive “Velcro” tape (not included).

7. CanopyIf you wish to fit an optional pilot figure in the cockpit of your MX2, then do so now, (image 23). We recommend that you drill two small holes as shown in the clear canopy to allow any heat to disperse, (image 24). Carefully apply adhesive as shown to the foam section of the canopy assembly, (image 25). Use the adhesive sparingly and position the clear canopy in place onto the moulding, (image 26). Allow to dry thoroughly before attempting to fit

22 the assembly in position on the fuselage.

The canopy is held in position with a rubber retaining band positioned in the fuselage and the pre-installed magnetic catches, (image 27). Do not attempt to fly the model without the canopy secured in position with the retaining band attached.

27 8. Propeller Remove the propeller fixing nut and washer from the motor shaft. Slide the rear section (back plate) of the spinner onto the shaft making certain that the square “Key” of the shaft locates into the corresponding aperture in the back plate moulding. Slide the propeller onto the shaft, followed by the washer and secure in place with the 10mm propeller nut, (image 28). For optimum performance, some pilots may wish to balance the propeller.

28 29

The propeller nut needs to be tightened very securely. Position the spinner cone in place over the propeller and secure with the M3 x 30mm screw, (image 29).

ExhaustGlue the decorative exhaust into position as shown using the supplied adhesive, (image 30).

30Final checks

Check that all control hinges are securely glued in place. In the event of any hinges not being glued, please use the adhesive supplied. Check all fixings and fasteners on the model are secure, including snap links, servo screws, wheel retaining screws etc. Double check the control surfaces are moving in the correct directions in relation to control inputs from your transmitter.

8

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: 10mm deflection each way. Ailerons: 8mm deflection each way.Rudder: 15mm deflection each way.

Centre of Gravity

The centre of gravity of your MX2 is 100mm back from the furthest forward point of the wing, (image 31). Using the recommended 3300mAh 4S Li-Po battery in a fully forward position in the battery compartment this centre of gravity should be easily achieved without the requirement for any additional ballast. If you choose to use a lighter battery, (i.e 2650mAh 4S Li-Po) you will require some lead or other suitable ballast to achieve the correct centre of gravity. 31

Battery

Your flight battery (not included) needs to be firmly secured in the battery compartment to prevent it from moving, (image 32).

Experienced pilots often have a preference for the method of securing flight batteries. These include the use of retaining straps or self-adhesive “Velcro” type fixings. Whichever method you choose, we recommend the addition of a small battery compartment “plug” which can easily be manufactured from the foam packaging material 32your model was supplied in, (image 33).

The plug should be cut slightly oversize to create an interference fit and positioned immediately behind your flight battery to prevent any movement, (image 34). The addition of a self-adhesive tape tab around the plug makes for its easy removal, (image 33). The foam plug should not fill the battery aperture completely as this would restrict airflow through the fuselage.
