Which is better? A blond or a brunette?
Depends on what you want it for. To pass an exam or to fly a helicopter with insight and skill? Dont know about Pooley's, but I'd rate Wagtendonk high on the theory side, and Coyle (Cyclic and Collective) high on the applied side. There are many others which I have found useful as well. A recent thread solicited recommendations on books on helicopter aerodynamics - you might search for this for a number of useful books. In the event of a fire in which I could save just one of my helicopter books, it would be Coyle. I recently made the transition from plank to helo, and Coyle's book took some of the mystery out of it. Highly experienced helo pilots might consider Cyclic & Collective too elementary, but as someone relatively new to helicopters, I found it a goldmine of practical info that might have taken many years to discover from first hand experience.
That being said, you wpould probably do well to own a shelf of helo books, as no single one does it all well.
