User manual GRAUPNER POWER SUPPLY 13.8V 0-20A

[. . . ] IMPORTANT SAFETY NOTES You have acquired a model helicopter with an infra-red remote control system. However, we as manufacturers have no control over the way you build and operate your RC model aircraft, nor how you install, operate and maintain the associated components, and for this reason we are obliged to deny all liability for loss, damage or costs which are incurred due to the incorrect use of our products or due to incompetent behaviour on the part of the user, or which are connected with such operation in any way. Unless otherwise prescribed by binding law, the obligation of the GRAUPNER company to pay compensation, regardless of the legal argument employed, is excluded. This includes personal injury, death, damage to buildings, damages due to loss of business or turnover, interruption of business or other direct or indirect consequent damage whose root cause was the operation of the model. [. . . ] If the rotors are damaged or broken, do not attempt to fly the model again, as it will be uncontrollable and could injure you. Do not fly the model close to people, animals, furniture or other obstacles. The operator of the model must be in full possession of his or her bodily and mental faculties. As with car driving, operating a model aircraft under the influence of alcohol or drugs is not permissible under any circumstances. Change batteries when the power LED expires immediately after switching on the transmitter. Locate the charge lead on the front of the transmitter, and insert the charge connector into the helicopter socket. Never allow the helicopter battery to touch or come close to any hot object (open flame, heating radiator), otherwise there is a risk of explosion. Never strike the battery with a hard object, as this could damage the cell. During the charge process the switch on the helicopter must be left at the OFF position. The battery can also be recharged from a PC using the USB charge lead supplied in the set: connect the charge lead to the USB socket of a PC, and the red LED in the plug will glow red. Insert the other end of the lead in the helicopter charge socket, and the LED will go out. Once you have learned the skill of keeping the Pico Star 1 Gyro hovering at a particular height, without rotating, you can deliberately alter the orientation of the fuselage (and therefore the possible direction of flight) using the direction control (right stick). The forward / back control (right stick again) is used to accelerate or brake the model in this direction; the helicopter is even capable of flying slowly backwards. By combining all the stick functions the model can be controlled in a similar manner to a `real' helicopter. Landing, terminating flight operations The Pico Star 1 Gyro can be landed simply by gradually moving the left-hand stick back towards you. After the landing the main switch on the model must first be moved to the "OFF" position, and only then the transmitter can be switched off. Note: towards the end of a flight the model will become increasingly unstable due to the declining battery voltage. fault-finding · After the initial charge you may find that the flight battery does not give its full capacity, resulting in reduced flight times. The LiPo pack only reaches its full performance after a few charge / discharge cycles. After a flying session · At the end of a flying session the model should be replaced in its original packaging to avoid the danger of accidentally bending or distorting the rotors. If you know you will not be flying the helicopter for a long period, ensure that the model is switched off, and remove the dry cells from the transmitter. care and maintenance · Clean the model carefully after every flying session. [. . . ] Warning: never fly the model in a hall with fan-assisted air-conditioning; this has the same effect as quite a strong wind, and could easily push the model out of transmitter range and allow it to go out of control. Flight time: with a fully charged battery and flat calm (indoor) conditions the helicopter will fly for between three and four minutes. As soon as you notice that the model is unwilling to take off and climb, it is time to recharge the flight battery. The motors become quite hot during a flight, and remain so afterwards. [. . . ]
