Flying the model Never fly your ALPINA 3001 Champ ELEKTRO in a nature reserve or any other protected site. Please don’t disturb the animals and plants which live in the countryside. Trees and bushes are the natural habitat of many birds, and also serve as nesting sites and general protection for them. Before you fly the model for the first time it is essential to take out a special insurance policy designed to cover modelling risks. These safety notes should be kept in a safe place.

Assembling the ALPINA 3001 Champ ELEKTRO Please don’t start work on the model until you have read through the instructions and understand the purpose of the various components and stages of construction. If you are not satisfied with the quality of any part, take it back to your model shop for replacement before modifying it in any way.
The servos are centred by switching on the RC system and setting the trims to neutral. The next step is to glue the servos to the servo well covers, but first you will need to solder the servo leads to the extension leads (already present in the wings), and remove the servo mounting lugs. Solder the joints carefully, ensuring that you maintain correct polarity, i.e. connect like colours of wire together.
Each aileron and flap pushrod is assembled using an M2 threaded rod, an M2 nut and an M2 clevis, as supplied in the kit. Note that the angled end of the aileron pushrods must be formed in such a way that the distance between the linkage hole on the servo output arm and the clevis linkage pin is 40 mm. For the flaps the same dimension is 45 mm. Final adjustment can be made later by screwing the clevis in or out on the threaded rod, once you have screwed the servo cover in place.
No. 2972 and 2973. In this case the servos are connected automatically when you plug the wing panels into the fuselage. The four incidence pegs must now be glued in the wing root ribs so that the wings have a fixed location relative to the fuselage, and cannot swivel on the wing joiner. Open up the rectangular holes in the root fairings on the fuselage, cutting along the marked lines using a rotary cutter and / or a file. Leave about 1 mm space all round the opening for the wing joiner.
While the wings are plugged into the fuselage, please check that the tailplane lines up correctly with the wings. You will find a small compression strut in the wooden parts bag. Install this component between the wings close to the trailing edge, and adjust its position to correct any minor production tolerances in the wing sweep angle. It is important to epoxy the compression strut in place at this stage.
Fuselage and canopy Installing the canopy latch Trim the canopy pin support rail (channeled hardwood strip) to fit inside the canopy. Carefully de-burr the steel locating pin, round off the end, and glue it in the support rail; note that the pin must project beyond the end of the rail by about 22 mm. Glue the pin support rail in the canopy in such a way that the pin projects by about 6 mm beyond the edge of the moulding.
The canopy can be fitted on the fuselage once the resin has cured: place the canopy in the recess, and engage the GRP tongue at the rear end. Push the canopy towards the tail until the pin clears the front flange, and can be engaged in the notch, then slide it forward again until the canopy fits snugly in the recess. When you slide the canopy forward, it will naturally centre itself on the fuselage flange.
Installing the RC components and the electric motor in the fuselage The three laser-cut plates must be glued in the fuselage to support the electric motor and the receiving system components. Attach the electric motor to the motor bulkhead using the retaining screws supplied with the motor. Place the electric motor assembly in the fuselage, working from the canopy opening.
Cut down the servo output levers to the shape shown in the photo, centre the servos from the transmitter, and push the output arms onto the servo output shafts. Screw the servos to the RC plate, then glue the plate in the fuselage, positioned as shown in the photo below. The flight battery can be fixed to the battery plate using Velcro (hook-and-loop) tape. Once you have established the correct Centre of Gravity, mark the battery’s position using a pencil.
The tailplane The all-moving tail crank is factory-installed on this model, but you may need to make minor adjustments to the guide slot for the rear tailplane joiner wire. Plug the tailplane panels into both sides of the fin using the two 3 mm Ø steel dowels: the one dowel fits through the front pivot hole in the fin, the second through the rear hole in the crank, working through the machined slots in the fin. The two tailplane panels can now be pushed onto the steel dowels on both sides.
Assembling the ALPINA 3001 Champ ELEKTRO Fit the rectangular wing joiner through the fuselage. Slide the wings onto the joiner to the point where the servo extension leads can be connected. Finally push the wings in until the Multilocks engage, and hold the wings firmly against the fuselage. Important: the wing and tailplane panels must be held securely in place; it must not be possible for them to slide outwards, away from the fuselage.

Repeated hand-glides at a flat-field site should be avoided at all costs. The most dangerous time for any model is when it is close to the ground, and hand launches are therefore by their nature extremely hazardous. There is hardly any time to correct the controls, and a hard landing can easily damage the model. Range testing (even for experts) Ensure that your transmitter and receiver batteries are freshly charged according to the battery manufacturer’s recommendations.
approximately correct. It is bound to fail if the model is a long way out of balance and / or there is a strong wind. In breezy conditions it is difficult to set up the model for normal cruise speed, as it is hard to judge its speed relative to the surrounding air. Trim the model carefully for normal cruising speed, which should be comfortably above stalling speed. The model should show no tendency to “hunt” up and down, or mush along close to the stall. It should respond normally to all controls.
way down the valley, the cool air meets warm air flowing gently uphill, and pushes it up and away as if cut off by a knife. The result is an extremely powerful but bumpy thermal bubble. The pilot’s task is to locate the rising warm air and centre your model in it. You will need to control the glider constantly to keep it centred, as you can expect the most rapid climb rate in the core of the thermal. Once again, this technique does demand some skill.
the best route to it. Look around for landmarks in the countryside which will help you locate the model when searching. However, the main point to remember when scratching for a thermal below launch height is “don't panic”: remember that in almost every case it is the pilot that is the problem, rather than the model. If you have a flying colleague who tries to help by giving a continuous commentary and giving what he thinks is useful advice all the time, tell him to shut up.

Be sure to read right through the instructions covering assembly and operation of your model before you attempt to operate it for the first time. You alone are responsible for the safe operation of your radio-controlled model. Young people should only be permitted to build and fly this model under the instruction and supervision of an adult who is aware of the hazards involved in this activity.
model press are also good sources of information. The best course is always to join a club and fly at the approved model flying site. Adhesives and paints contain solvents which may be hazardous to health under certain circumstances. Read and observe the notes and warnings supplied by the manufacturer of these materials. The operator of the model must be in full possession of his or her bodily and mental faculties.
completely unpredictable. Never leave your radio control system unguarded, as other people might pick it up and try to use it. If you are to fly your model safely and avoid problems, it is essential that you are aware of its position and attitude throughout each flight - so don’t let it fly too far away! If you detect a control problem or interference during a flight, immediately land the model to prevent a potential accident. Model aircraft must always give way to full-size aircraft.
5. 6. 7. 8. The charge process must be supervised even if you are using a fully automatic charger. Note the maximum permissible charge current printed on the pack or individual cells, and do not exceed that value. Excessive charge currents can cause NiMH cells to overheat. If the battery heats up to about 50°C when on charge, the charge current must be switched off immediately. When NiMH cells get hot, the pressure inside the cell case rises greatly.
