What makes a plane "short coupled?"
I have been working on an enlarged version of the old Hot Kanary biplane , similar as to what was published in M.A.N. back in the mid 80's. ( 1500 sq. in)
Here is a pic of a 1/3 scale mock-up made from cardboard and CAD plans.
Some people have been telling me that the plane is too " short coupled"
My question is how do you determine this? What is the technical definition of a plane's "moments"
The distance from the cg ( Leading edge of top wing ) all the way to the front tip of the spinner is 22.3 in. ( about 18" to the prop )
The distance from the CG to the approximate center of the horizontal stab is 37.4 inches.
Any thoughts appreciated.
