"Nova: The Four-Winged Dinosaur" addresses the issue of the femoral position

Martin and Burnham, while also briefly dusting off the "debate" over the
theropodan ancestry of birds for those who have been out of the loop for the
last 40 years.

Interestingly enough, while the model used by Norell, Ellison, and Brougham seems to involve rather less fudge factor, both teams tried to force the hindlimb feathers to point laterally in some fashion - a starting assumption which may not be very robust.
