I think I mentioned it earlier in the thread, but the AVP Queen mechanical puppet is actually NOT much bigger than the A2 one was.
It is just that in the film AVP whenever the Mech Queen was used for the shot, there was very little on screen for scale.
Most of the shots involving scale, and the legs, where all CG, where she had "size of convenience syndrome", and appeared 24ft tall.
If you have the ADI book, you will also notice that the Mech Queen in AVP still had the "high heels", and they were taken off of the CG Queen too.
If you want a scale reference for AVP, notice the Queen chasing Lex through the whale bones, or when she fell into the building.
