A brushless motor is an electric motor without brushes, which, compared to a brushed motor, is characterized by a higher efficiency, lower wear, and reduced weight. You have a basic understanding and possess the necessary experience and suitable tools to correctly wire your model and safely put it into operation if needed. RTF models are ready to use straight out of the box. You receive a complete package with a pre-assembled model and a compatible transmitter - unpack and get started, that's the motto of Ready to Fly models. Due to their ease of use, this type is ideal for entering the world of model sports. The DJI Enterprise Care additional insurances cover various risks that can typically occur when operating a multirotor. The coverage includes replacements for operational errors, crashes, collisions, water damage, and signal loss. Thus, the service package significantly contributes to securing your investment and minimizing risks. However, it does not include liability insurance, which must be purchased separately according to applicable regulations. Activate the service within 48 hours along with a device, and you will have the option to receive up to two replacement devices during the insurance period. The resulting contractual relationship exists between you as the customer and the service provider DJI Enterprise. Please note that some Enterprise products already include DJI Enterprise Care packages as standard manufacturer services. The corresponding insurance coverage can be extended for an additional 12 months with a separately available Renew package. The number of replacement devices is then reduced to a maximum of one replacement device during the term.
