AEX Wedge used on which models?
 

I know the trailing edge of all the flight surfaces and flaps on the -9 use an undrilled AEX wedge and the -7 uses it for the trailing edge of their rudder, but what about the other models?

One more data point: No wedges on my 2015 RV-8 empennage.

RV 10 uses the AEX wedges for the control surfaces and the RV-14 uses them for all but the elevators.

None on the RV-3B.
