I think that's all l I had to hear. That's fixes everything if in your model the wing stays folded until apogee or the beginning of the downstroke. Sort of like a swan dive, except no swan and no dive.

It can certainly be done that way, but it isn't necessary and isn't efficient.

Last question, how long of a run (in terms of # of footprints) -- to gain speed to load the forelimbs -- before the leap? Perhaps zero for tiny pterosaurs, more for larger ones?

Zero for the largest ones. JimC
