hey barry,

i was trying to make a different blade for the a400m, so that the kink would no longer be there. i wanted to make a straight blade with airfoil sweep. as i started to work on that, i noticed something seems broke with prop design opt. i need to look into what's run. once i get that fixed i think the blade you are working with will change again. it was made using the broken version of opt. so it's not sized to the inputs specified. i'll get back with you when i get this fixed.
