WACO YKS-6 / YKS-7 performance and specifications


 

A series of four to five seat cabin biplanes were produced from 1935. These were a little larger than earlier Waco types, and more luxurious. They generally had short span lower wings and quite elegant lines, and sold well despite higher prices. The YQC-6 was offered with a choice of no less than seven different engines, the Jacobs L-6 being the largest.

A number were exported to Canada and India, and some were fitted with freight doors.

A custom cabin version was also available. information kindly supplied by Lars & Angelika Opland


The older ones, circa 1935 (YOC, CUC, etc.), were shorter than later ones by 1 foot. The strong recurve in the fuselage profile aft is the main recognition feature


From 1936 on (EQC-6, ZQC-6, etc.), the fuselage is 1 foot longer with straighter lines in the aft profile. Rear windows were not always present, so are not recognition features

The wings are a major recognition feature between standard cabins & custom cabins. In the standard cabin series you have true biplanes with bottom wings that are the same cord & not much shorter in span than the top wings. Custom cabins have bottom wings that are markedly smaller in both span & cord.
