Same!! all the wing spec are the same as in 1.1.3 but some how the wing is shorter in 1.2.1. I didn't know about the length limit, but in the B9PWing mod it seems that all the control sliders are limited to one scale.. I can no longer click the little rectangular button to change the scale of the slider when its at maximum. Don't know if this is a game limitation or a bug in the mod.
