Used later in the fuselage kit. Don't misplace them.
Ok, Tom023 asked me about it and I was wrong.
I was remembering the 2 bell crank angles (F-01037A) which are supplied in the empennage kit, but not used until the fuselage kit. I looked, and I still have the AS3 plate myself and I am finished with the fuselage, so I don't know when it might be used.
