Hello having severe issues with SAS while in flight with a particular set up on a plane everything regarding CoM and CoL, seems to be correct the CoL is behind CoM. but the second I enable SAS in flight the whole craft will go begin a full pitching up and/or down violently without stopping, sometimes it simply occolates between full pitch up or pitch down other times it holds full pitch up/down and makes a loop without me touching anything. Help would be appreciated
