- Page 2 Thank You for buying the model of Backfire F5F. Backfire F5F is a full-carbonic model, it is made by lamination into negative forms. Backfire F5F is suitable for the competitive league , F5B/7, and for the hobby flying as well. The model was designed for competitive flying and its design results from the latest innovation of the F5F category.

We press down the cut cooling entrance under the fuselage level and we fix it with help of balsa –...
- Page 6 It is possible to make the cooling air´s entrance in the wing with help of a carbonic tubule with the 14 mm diameter. The place for leaks is marked on the wing. BackfireF5F Page 6...
- Page 7 2.2 V-tail shoulder The carbonic pins must be ground at their ends with help of a turn-bench and so their edges are flicked off. Those pins that will be sticked up in the fuselage must be roughened, so the pins will hold to fuselage well. We glue everything with the epoxide. Next we cut throught the holes for the butterfly-lever.
- Page 8 Obr. 4: The carbonics pulls for V-tail We screw the servos into prepared barrier and we glue their bolts with the fusing gun so that we could unloose the bolts in case we suffuse them by the epoxide. We secure the servos cables in the same way.
- Page 9 We give the barrier into the fuselage and set the servos´ neutrals. At the end of fuselage we screw the next boll cups. It is absolutely necessary that the pulls are put through the guide tubule in the middle of the fuselage!!! Picture 6: Putting in the servos and setting up the neutrals We apply the epoxide with microballons thickened by aerosil on the barrier in the way that the mixture do not slump.
- Page 10 Picture 7: Glueing V-tail servos Next we can put two balsa-battens with 1mm thickness between ball pivots on the servo and the fuselage-bottom. The battens ensure the space needed for ball pivots movement. We check the quality of glued joint. It is necessary to fix the butterfly to the fuselage before the test flying.

- Page 13 3 Wing 3.1 Horns and Pulls We glue the levers belonging in the flap in the distance of 7,3mm from the axis of rotation and the levers for wings in the distance of 4,4mm from the axis of rotation. The lever of the flap´s servo will have the hole in the distance of 7,3mm from the axis of rotation and the lever of the butterfly´s servo in the distance of 3,0mm...

- Page 15 3.2 Cabels of servos and servoholder We shorten the servos´cabels up to 4cm of distance. We solder the pins from the crushing bar on the servos´cabels pulled through the wing. Or we can crimpen the original pins from the servo-connector. We prepare the septa from plywood 1,5mm for each servo. Picture 11: The cables of servos and septa of servos 3.3 Connectors Wing/Fuselage In case we work with the three-piece wing, we have to solder the connectors into wings...
- Page 16 The length of cables to the receiver should be c. 9cm. We strip cables, tin-plate them and we put the shrink- spaghetti insulation on them. We solder cables to the connector MPX, strip the isolation with the hot-air gun and fix all with the fusing gun. We use the same work procedure while soldering the connector MPX in the wing.
- Page 17 3.4 Sticking up the servos into wing First we set the neutrals to all servos. We stick up the servos into wings with an epoxide. We ensure the ailerons and flaps to the wing in zero deflection by using a cellotape and we set the neutrals of all servos again.

- Page 19 It is necessary to use the external voltage supply for power supply. It is more reliable to use the connector 2mm instead of switch. The connector 2mm has a better contact. The conductors to the battery have the cross section 0,5mm Picture 16: Voltage supplies for the deck equipment 4 Others picture BackfireF5F...

We place the receiver in front of butterfly´s servos. We hold the regulator also with nails Dual- lock on the top of the front part of fuselage.
