Ercoupe history and lore

[Kenneth N6543q Dede Anderson]

I was just thumbing through Stanley G. Thomas's book "The Ercoupe".  It's a good book on the background of the coupe and one of the things he mentioned in the book was the Ercoach (pp. 69).  According to the description in the book it was to have been a five place pusher twin.  Do any of you know anything about this aircraft?  I would be interested to hear or see anything you might have on the subject.  Also, I was wondering if anyone knows if Univair also owns the type certificate for the A-4.  And, finally, do any of you know anything about the wooden Ercoupes (according the the book 2 flight test and 1 ground test) produced in 1940?    I would love to hear anything you can tell, and let me know what some of your favorite books on the Coupe might be.  I'm always trying to grow my aviation book collection and I'd appreciate any input anyone might have.   Thanks and I hope that you all have a chance to enjoy "Flying the coupe".   Ken and Dede Anderson Alon N6543Q Norman, Oklahoma
