No, you would not see the turbine in any of the R2 shots. Nothing was removed from the set piece in order to film these shots. Due to the angle of the shots and the lens used, it would be out of shot. As for seeing the guns, well no you certainly wouldn't see any of those as the wings are closed ( although the wings on the set were actually set to the open position and cut off mid way along the wings) . So there is nothing to fix regarding any of these. But i'm very surprised that, with all this scritiny going on about these shots and where the turbines should be, that not one single person noticed the matte problem with the turbine we actually do see in one of these shots leaving Hoth. The turbine behind R2 has a static matte, yet the x-wing banks very slightly and the matte cuts the top of the turbine off. ;)

I am extremely happy you won't be altering the replacement matte painting :)

But what you have said here, is something that I pondered, that the actual engine that we see is incorrect.

If what you are saying is the case then the engine is in the wrong position i.e. to high?

Are we talking a different kind of fix? Or just leave it as it is? Either way I am not pushing, I just felt that something was not right with this, and if what you are saying is true for which I believe you are telling us valuable information here about it. Then well I kind of feel like you have Answered very well but also raised a few other questions because the engines pivot up higher in attack (open) position. So even if nothing get's changed with it, it's now better to know a bit more about what is going on.

Get some good rest today after hard days night :)

One last thing I had a look after what you said and then I noticed...

Is that the arm, that they use to shake the x-wing? Gimble arm or what ever it is to create movement?
