For the student learning to fly helicopters in the 21st century, this book is one of the essential keys to flight.
Helicopter pilots need to thoroughly understand the consequences of their actions, and base them upon sound technical knowledge. This textbook provides a foundation by explaining why the helicopter flies and, more importantly, why it sometimes doesn't. It examines the aerodynamic factors associated with rotor stalls, mast bumping, and wind effect, as well as maneuvering flight to include the hover, forward flight, flare, and auto-rotation. Helicopter design and components, performance, and weight and balance are covered, along with special techniques such as different types of takeoffs and landings, operating on sloping surfaces, sling operations, mountain flying, and helicopter icing. Technical knowledge and sound handling are the crucial ingredients that make a safe pilot.
This second edition benefits from additional discussion of the NOTAR system and strakes, as well as frequently misunderstood principles of airspeed and high altitude operations. The book also concludes with a multiple-choice practice examination; used in conjunction with quizzes for each chapter, the reader can test their grasp of helicopter aerodynamics.

A good value, works well.
Size: 1 Tier-8.5''Wx10.5''Dx2.5''H, Size: 1 Tier-8.5''Wx10.5''Dx2.5''H
It works great, and a good value for the price. Super easy to install, comes with a template (you probably wont need), screws and a screw driver. Easy peasy It will not affect the performance, but it is a little flimsy. Great service and price. Quality packaged as well.

Great quality product
Size: 2 Tier-5.5''Wx10.5''Dx9.5''H
The product quality is great. Assembly is needed but relatively easy. The moving shelves have a premium slide and catch at the end. I was impressed by this the most. The only potential small issue were the inside protectors it came with. Not that they're poor quality, they have a decent thickness. But during assembly they kept falling out easily because there wasn't enough catch on the shelf itself. In actual stationary use, this may not be an issue. But would have been better if the shelf held onto them more. You may not notice it when you put things on the shelf on top if it but they're also not a great color/texture match. Semi-opaque white plastic on a black metal rack; it cheapens the product. And in case you were wondering, magnets can stick to it. Overall though, I am pleased with the quality of this product.
