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. [. . . ] As with car driving, operating a model aircraft under the influence of alcohol or drugs is not permissible under any circumstances. 5 V AA-sized dry cells are included in the kit (replacement Order No. Change batteries when the power LED expires immediately after switching on the transmitter. Ensure that the battery cells are fitted with correct polarity. Never fit different makes of battery cell. Locate the charge lead on the front of the transmitter, and insert the charge connector into the helicopter socket. Disconnect the charge lead at this point. This method of charging takes about 30 minutes. 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. The battery should never be left on charge unsupervised. If necessary, turn the trim knob to trim the helicopter, then use the sticks to control the model. Controlling climb, descent and hovering The first step in getting maximum fun out of the Pico Star 1 Gyro Helicopter is to establish a stable, smooth hover. After a little practice the multi-channel control system can be used to fly the model in a similar manner to a "proper" model helicopter: When the machine reaches the desired altitude, hold the left-hand stick (climb / descent) as still as possible in the position where the helicopter neither climbs nor descends. If the model starts turning in either direction, use the right-hand stick to counteract the movement; in this way you will soon achieve a steady hover. 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. When this happens you must land the model and recharge the battery. [. . . ] Don't touch the motors until they have had a chance to cool down to room temperature. Disposal Fly until the helicopter battery is completely flat, or allow the rotors to spin until they come to a halt. remove the fuselage by unscrewing the two screws. Cut through each wire of the battery seperately (to avoid short-circuits), insulate the cutted ends separately, and remove the battery. [. . . ]
