How could I set up my “set isflying” similar to the is falling, I can’t seem to find a way to fire this like the is falling due to only being able to have 1 plugged into is valid.

You know you can plug one in after another right? so take the arrow pin from the rightmost SET node and add it into the put of the IsFlying set node. OR use a sequence node out of the IsValid to clean things up a bit.
Wow, thanks so much, feel stupid now :L
