3 Dear customer, Congratulations on your choice of a factory-assembled model aircraft from the jpower range and thank you for placing your trust in us. Very little preparation work is required to get this model ready to fly. To operate your new model safely it is important that you read through all of the instructions and safety information included with your model, before you fly it for the first time. The illustrations in this manual show the Silver version of the model with factory applied decals. The power system Assembly and Operating Manual SCREAMER To fly the SCREAMER you will need a radio cure (harden) to the point where the joint can be control system with at least four channels. 2.4GHz placed under stress. radios systems are recommended, similar to the unit included with our deluxe version. Kit contents The power for the receiver is drawn from the Fuselage, complete with motor, speed controller electronic speed controller s integral BEC system. and servo. Integral wing panels with L.H / R.H. ailerons and The electronic speed controller is located inside of servos the fuselage, in front of the ducted fan. Tailplane and elevator Fin When you wish to fly the model, always make sure Factory-fitted propeller and spinner the transmitter is in the OFF position. Move the 2 X Aileron pushrod, Two Z-bend throttle stick to the OFF position as well. Then 2 X Control surface horn connect the flight battery to the electronic speed 1 X 3S1P LiPo battery,950 mah, 20C controller. The model is powered by a brushless outrunner motor and ducted fan, both of which are factory-installed on the Ready-To-Fly version. The motor is connected to the electronic speed controller which is factory calibrated on the Ready-To-Fly version. All that is required is to charge the Li-Po battery, following the safety instructions, and connect the battery to the electronic speed controller. The radio control system Switch off in the reverse order: disconnect the battery from the electronic speed controller first, and then switch off the transmitter. Glued joints, suitable adhesives Foam safe epoxy is recommended and available from most reputable model retail shops. Trial-fit all parts dry before applying glue. Follow the recommended curing time suggested by the glue manufacturer. Allow the glue to fully 3

If not,swap over the connectors at the receiver. - Check the neutral position of the control surfaces;you may need to screw the clevises in or out to correct any discrepancy. -Stand behind the model. - check the direction of rotation of the servos: -Move the aileron stick to the right (a), and the right aileron(a) must rise up, the left aileron (b) fall down. -Pull the elevator stick back towards you (d),and the trailing the elevator stick back towards you (c) -If either function works in the wrong way, correct it using your transmitter s servo reverse facility for that channel. 10 Fig. 10 Checking the power system -Hold the model securely. -Remove any loose objects such as cloths, tools,etc from the area in front of the model, as they could easily be sucked into the ducted fan. -Open the throttle (stick forward): the motor should now run. and you should feel a strong air flow rushing out from the tail end of the model. -Move the throttle stick back to the Motor OFF position. -Disconnect the battery from the electronic speed -Controller and then switch the transmitter off. 6

Assembly and Operating Manual SCREAMER 11 Fig Fig. 11 Checking the models balance -Place the flight battery in its compartment, without connecting.

When correctly balanced the airplane will remain horizontal, with the nose slightly down. -If necessary, adjust the position of the flight battery to achieve the correct CG.

When correctly balanced the airplane will remain horizontal, with the nose slightly down. -If necessary, adjust the position of the flight battery to achieve the correct CG. -Mark the battery location in the fuselage, so that you can be sure of positioning it correctly after recharging. -Pack scrap pieces of foam around the battery in its final position, otherwise there is a danger of it shifting in flight and altering the model s balance. - Charge the flight battery and the model is ready for flight.

8 - Switch the transmitter on, and connect the flight pack - Check the direction of rotation of the motor: when viewed from the front, the output shaft must rotate anti-clockwise. If this is not the case, perhaps because you are using components other than those recommended, swap over any two motor wires to reverse the direction of rotation. Note: whenever you are installing, adjusting or servicing the power system, keep well clear of the rotational plane of the propeller injury hazard. Ensure also that nobody stands in front of the model when the motor is running. - First disconnect the battery from the speed controller, and then switch the transmitter off. - The model is ready for flying once you have recharged the battery.
