The broad principles of flight as applied in full-size aviation are just as important to flying models, but these principles are not always recognized or understood fully by aeromodellers. Written specifically with aeromodellers in mind, Model Planes: Aerofoils and Wings is a practical guide to the aerodynamic principles of the 'aerofoil' and the way that wings produce lift, which is vital to establishing flight. Included are over forty ready-to-use aerofoil sections in a range of typical sizes, together with a detailed method of plotting these sections on a home computer, using Excel or a similar software. A comprehensive glossary provides clear explanations of the modelling terminology used, and diagrams illustrate key principles and themes. Written by a distinguished aerospace engineer with a passion for modelling, this comprehensive volume is perfect for the enthusiastic aeromodeller, whether starting out or looking to hone their craft.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ GARDNERS","offer_id":49731330146577,"sku":"NGR9780719815409","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0719815401.jpg?v=1751453958"},{"product_id":"aerofoils-for-aeromodellers-book-martyn-pressnell-9780273010159","title":"Aerofoils for Aeromodellers","description":null,"brand":"WoB","offers":[{"title":"- \/ - \/ -","offer_id":50735409201425,"sku":"","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":50735410118929,"sku":"GOR002999479","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0273010158.jpg?v=1750812664"}],"url":"https:\/\/www.worldofbooks.com\/collections\/author-books-by-martyn-pressnell.oembed","provider":"World of Books ","version":"1.0","type":"link"}
