download the "flying light twins safely" manual..I cant remember if it is an advisory circular or not....also go to this link..
http://www.aviatorlibrary.info/Initial_CFI.htm and print out most of the duchess stuff....trust..but verify..some of the information is incorrect.
Learn, study, and become one with Vmc..do not just memorize it (rote) learn it to the correlation level and beyond.
I am far from a multi expert by any means but I have 120 pic in the duchess and did my initial cfi in it so I have some current knowledge on it...what did you want to know?
