I have tried rigging the right wing first on my Ventus cT but in rigging
the left wing first, I have the benefit that I can partially insert the
main
pin. This helps prevent the left wing being pushed back out if the
rigging is not quite aligned when I rig the right wing.

As everybody else has said, it is vital that the wing stubs are properly
aligned. If you don't do this, there is going to be a helluva lit of
grunting and cursing. :-)
