In Victory of the Daleks, the Daleks hit three moving aircraft out of the sky at angles clearly exceeding 45 degrees, with no wasted shots. The accuracy isn't what I'm concerned about; the question is how a Dalek can hit a target that's more above him than in front.
Through all the posters, episodes and minifigures, Dalek shells appear to have fixed barrels, incapable of rotating or turning.
Can the Daleks elevate or depress their gunsticks? Did Churchill outfit the Daleks in turrets or anti-aircraft platforms?
Considering Bracewell's advanced technological abilities, I'm inclined to believe the latter.
I'm a new fan to the series and don't have the background to verify my intuition. Have Daleks ever shot at targets on different elevation than their own?
