John:

You are right. I forgot the B-247. And didn't the early Stout tri-motors (1-AT & 2-AT) also have the reverse rake before Ford took over the design? And, if I remember, the first that were labeled Ford, also? I know the 3-AT was conventional.

And with that much weight out on the wings of your QK I don't think you are ever going to get a fast roll rate, just another reason to stay with twins. Haw.

Looks good, John, glad it was successful. And thanks to both you and Robby for the pictures.

Bill.
