What is the favored technique for aligning a wing into a full fuselage? Profile planes are simple, straight leading edges again simple. This one has a tapered leading edge straight trailing edge. J.D. Falcon.

What has worked for me is to mark a true centerline on the fuselage using pins and thread.  To get the horizontal alignment I measure points on the wing equal distances from the center then measure the pin to tail and pin to nose distances until they are equal.
