Found all the books at Turbine Traders and they also had a local FAA
approved book on how to use the Chadwick , the service department was were
very helpful on the use. The book covers all the applications of propeller
tail rotor main rotor ect. The maintenance books on the chadwick, strobe and
calibrator were very good and easy to understand the concept. Tried it on a
PA-23 worked well after the second plotting and angle shift.

I could give you the operation and service manuals but who is going to
teach you how it all works together? The model 11 calibrator is not an
easy
piece of equipement to understand. It works very well but you have to
know
how it gives out its readings.
