RE: Help I.D. a old book
A quick search makes me think it is the right one. Inside his book it dealt with Jetex, and 1/2a powered Helos, free flight of course. But, it had a lot of good info, and was a favorite to read at the library. Many of these books are no longer there, and that one page was all I had to go by. It would be cool to have others name some good books that deal with 1/2a in some form, the older books add much in the older stick and tissue builds.
My thanks to Sir Crashallot for his efforts, I never know about this search type, and will try to use it for other books.
