PROPO PRIMER
The manual was of 81/2 X 11 size and count 56 pages. There are many bautiful black and white photos and color drawings but no electronic projects.
The argouments are divided in ten capters
evolving from the simplest analogue single channel proportional up to the modern
"digital" system
Interesting is the part about the "Galloping
Ghost" well 
described and
with plentiful of color drawings that was useful to me to really understand how this
genial system worked!
Further passage are from the simple systems
for independent rudder and elevator up to dual and triple proportional.
Much of these systems are described from then on the market firms and many not so young modelers have matter of nostalgya!
In the "Full House" capter we see
the one time famous names of
the first real full independent channel
proportional radios as LOGICTROL, CITIZEN-SHIP and HEATHKIT
