Before the start
Clarify with your insurance company whether the operation of a radio- controlled model is covered by insurance (liability insurance).
If you are not yet experienced in controlling RC models, first familiarise yourself with the reactions to the control commands on the standing model. If necessary, consult an experienced model athlete or a model building club. If necessary, seek the support of an experienced pilot/driver.
Check the remote control system and the model for functional reliability and visible damage, such as defective plug connections or damaged cables, before putting it into operation. All moving parts must function smoothly, but without bearing play. Check all screw and plug connections, wheel nuts and electrical contacts for tightness, as these can become loose or detached during transport, while driving or in the event of minor accidents. Fasten excess lengths of cables in such a way that they cannot get into moving/rotating parts. Cables must also not be kinked. Make sure that all batteries are fully charged and not damaged.

Driving/ Flying
Do not drive/fly if your reactions are restricted (e.g. if you are tired or under the influence of medication or alcohol). Incorrect reactions can cause serious personal injury and damage to property. Do not drive if you have the slightest doubt about the perfect technical condition of your model/remote control system. Always maintain direct visual contact with the model. Operate the model only on private property or in places designated for this purpose. Observe the conditions and regulations for the terrain.
When operating a model, always ensure that no parts of the body or objects in the danger zone of motors or rotating parts. Regularly check all screw connections and fastenings, as these can become loose or detached during operation. In the event of a malfunction, stop operation of your model immediately and eliminate the cause of the malfunction before continuing to use the model. Avoid driving in low outside temperatures, as this reduces the battery capacity and the plastic of the bodywork loses its elasticity and splinters easily. Do not expose your model and the remote control system to direct sunlight, moisture, heavy soiling or extreme heat/cold for long periods. Do not drive in crowded areas, towards people or animals, in nature reserves, at night, under power lines, radio masts or during thunderstorms. Electrical fields and atmospheric disturbances can affect the signals of your remote control transmitter, in rain or damp conditions, otherwise the electrical system will be damaged. Please note that RC models must not be driven on terrain where there is public transport.

Intended use
The product is designed exclusively for private use in the model building sector and with the associated operating times. This product is not approved for commercial or industrial use or for continuous operation. Improper use can lead to personal injury and damage to the product and the associated risks such as loss of control over the model, short circuit, fire, electric shock, etc.
Follow the safety instructions in this manual. They contain important information for handling the product. The product is suitable for children under 14 years of age only under adult supervision. Arbeiten

Notes for batteries and rechargeable batteries
Keep batteries out of the reach of children and pets as they may accidentally swallow the batteries. In this case, consult a doctor immediately!
Leaking or damaged batteries can cause burns if touched. If skin or eyes come into contact with the electrolyte, rinse immediately and thoroughly with clear water. and see a doctor. Use suitable protective gloves when disposing of the defective Batteries. If you notice any abnormal smell, discoloration, excessive heating or deformation of the battery, disconnect the battery from the charger or consumer immediately. Dispose of the battery!
Conventional alkaline batteries (1.5V) are intended for single use only and must then be disposed of properly. Dispose of empty batteries or defective rechargeable batteries in an environmentally friendly manner at authorised collection points. It is prohibited to dispose of them with household waste!
Batteries must not become damp or wet. Also avoid the formation of condensation water. Never expose the batteries/rechargeable batteries, the charger and the model to adverse environmental conditions (e.g. wetness, excessively high or low ambient temperature, sources of ignition or open fire, dust, vapours, solvents)! Avoid heavy soiling and excessive mechanical stress on the battery and never pull the connecting cables! Never mix batteries and rechargeable batteries at the same time in one device! If no brand-new batteries are used to power the transmitter, ensure that there is sufficient residual capacity (battery tester). Always replace the complete set of batteries, not just individual cells. Always use batteries of the same type and manufacturer. Do not mix batteries with different charge levels. Make sure that the polarity is correct when inserting batteries into the battery holder. If the polarity is incorrect, not only your model but also the battery will be damaged. Batteries must never be short-circuited, damaged, disassembled or thrown into an open fire. There is a risk of fire and explosion!
If the battery gets hot, disconnect it from the charger immediately! If the model is not used for a longer period of time, remove the batteries or rechargeable batteries from the remote control and from the model in order to avoid damage from leaking / deeply discharged batteries.
