I'm trying to make B2's aileron system (use 2 ailerons on 1 wing deployed at opposite angle to creat a air break and there for Yaw control). My current solution is controling the ailerons' deploy angle by Kal-1000, and link the kal-1000's play position to yaw input. I ran into the problem of can't find a way to make Aileron Airbreak automaticlly return to 0 after i finish pressing the yaw input (in this case A or D), it's stuck on whatever the KAL play position is. Is there a way to play the KAL-1000's play positon only when pressing a button and reset automaticlly when that button is releaset?
