I just got my copy of Ray Prouty's "Helicopter Aerodynamics" from
WWW.HELOBOOKS.COM
Ray used to write an easy-to-read column on helicopter aerodynamics for Rotor &
Wing magazine. Later they compiled these column into 3 books, Now all 3 are
available in one volume from Helobooks. This is not a cheesy Xerox copy as I
feared it might be. It is a first class book of nearly 600 pages.
Happy reading, Tom
