The selection and variety of aeroplanes and helicopters under 100 g take-off weight has now become very large. These small and light models have long outgrown their infancy! Most of the models available for purchase come out of the box ready to fly. Nevertheless, the real model builders can rejoice, because there are also real kits for mini models for sale. Occasionally you can even find a construction plan for such a plane. This book brings some system into the diversity of the offer, so that the reader can selectively pick out the model that best meets his requirements. After a bit of theory, Hinrik Schulte presents a selection of 25 mini-models and has divided them into different categories according to evaluation criteria such as suitability for beginners and flight possibilities. From the content: • Development history of the mini models • Degree of prefabrication and scope of delivery • ARF, BNF models and RTF sets • Brief introduction to the technology • Radio transmission: Infrared, MHz and GHz technology • Transmitters, receivers and servos • Battery technology, charging technology, motors and controllers • Classification into model categories • Simple aerobatic models • Mini-Warbirds • Mini models with brushless drives • Helicopters and other rotorcraft • Coaxial helicopters, micro-helis and quadrocopters • Storing, transporting and repairing mini-models • Recycling defective models • The craft project 3D site

Modelling and Control of Mini-Flying Machines is an exposition of models developed to assist in the motion control of various types of mini-aircraft: • Planar Vertical Take-off and Landing aircraft; • helicopters; • quadrotor mini-rotorcraft; • other fixed-wing aircraft; • blimps. For each of these it propounds: • detailed models derived from Euler-Lagrange methods; • appropriate nonlinear control strategies and convergence properties; • real-time experimental comparisons of the performance of control algorithms; • review of the principal sensors, on-board electronics, real-time architecture and communications systems for mini-flying machine control, including discussion of their performance; • detailed explanation of the use of the Kalman filter to flying machine localization. To researchers and students in nonlinear control and its applications Modelling and Control of Mini-Flying Machines provides valuable insights to the application of real-time nonlinear techniques in an always challenging area.

Examines new technologies that allow enthusiasts to access areas with electric models which were previosly inaccessible. Offers advice on choosing a battery, tethered and free flight, simple and advanced radio control, indoor flight, build-it-yourself kits and exact scale flying.

Unmanned Aircraft Systems (UAS) are a rapidly evolving technology with an expanding array of diverse applications. In response to the continuing evolution of this technology, this book discusses unmanned aerial vehicles (UAVs) and similar systems, platforms and sensors, as well as exploring some of their environmental applications. It explains how they can be used for mapping, monitoring, and modeling a wide variety of different environmental aspects, and at the same time addresses some of the current constraints placed on realizing the potential use of the technology such as s flight duration and distance, safety, and the invasion of privacy etc. Features of the book: Provides necessary theoretical foundations for pertinent subject matter areas Introduces the role and value of UAVs for geographical data acquisition, and the ways to acquire and process the data Provides a synthesis of ongoing research and a focus on the use of technology for small-scale image and spatial data acquisition in an environmental context Written by experts of the technology who bring together UAS tools and resources for the environmental specialist Unmanned Aerial Remote Sensing: UAS for Environmental Applications is an excellent resource for any practitioner utilizing remote sensing and other geospatial technologies for environmental applications, such as conservation, research, and planning. Students and academics in information science, environment and natural resources, geosciences, and geography, will likewise find this comprehensive book a useful and informative resource.
