Q's about Fw-190 A ailerons..
 

I think that the ailerons of the Fw-190 A5 were changed respect the A3 and A4 models; anyway I have seen several pictures with A4 models with the A5 ailerons, when these ailerons were introduced and really in which model? Perhaps it depens of the factory.
Also I have noted several A4 without the movable flaps on the lateral slots on the cowlings, again when these flaps were really introduced??

TIA
