Having read many books about aerobatics (but please don't ask me about my performance...) I come to the conclusion that this one is the best. But it is hard work to read it because Cassidy loves every detail. I mean, really every detail. Even those you never thaught about. For a quick and fast result, it's too much. for those who love to make science out of every single movement of the stick, it is the perfect choice.
I wonder why he wrote no special chapters about: Pulling out of hangar, entering the cockpit, cleaning the aircraft, leaving the airport by car. Alan Cassidy, a man with no lack of self confidence, should teach us about these items in his next issue.
His language sometimes is full with british sense of humor. Okay, I agree with the first advice to any writer: 'Never bore your readers!' But in some occasions, irony could be misunderstood. Especially in a book about flying.
For those willing to go the gravel road this book will provide a universe. The other ones maybe better delivered with also excellent guidelines like Michael Goulians books.
