New here too, and trying to figure which set to buy come September, thinking of the X-wing as I like the colour scheme and that new canopy is so much better!
Only set I was certain not to buy was the snowspeeder, which looks ugly and weirdly proportioned on the box, but the out of the box picture has changed my mind...
Re: Kylo Ren's Shuttle, looking at the picture, I cannot see how the wings could tilt, however, if you look on the pictures, especially the out of box one, there's a wing portion folded under the craft when the wings are retracted, and they fold out as the wings expend in flight position, giving the whole thing the look of a giant, ungainly tie fighter (maybe based on that giant rred tie transporter concept leaked early in ep VII production).
