chief_chaman478 It's not like I (or Kroom) don't know that, it's more about the fact they have merely around half as much backward thrust (possibly less, don't remember exactly) and front facing engines balance the overall thrust distribution. Your designs likely have problems with rotating, something that's more of a weakness to fighters (and walls/everything not a spinner or equipped with roof turrets) than you might imagine.
PS: The bigger hangar thingy uses way too much armor. Consider replacing the inner parts with structure and/or placing more thrusters.
