Got to build one today ... few thoughts below ....
first off it is a very very nice model and it goes together so well too - none of the usual gaps etc and all gun barrels apart from the stubber are open, so no drilling etc!!
tracks are a shite to do as the instructions arent overly clear, you have to start with a single link at back and then work forwards but once you got the hang of it it is fairly easy ... if you remember the tracks face up at the front and down at the back you are sorted
everything is a left and right side but this is not highlighted or raised in the instructions so be careful and usual amount of dry fitting
when building the side sponsons the instructions are poor again, there is a central 'arm' that can go in two ways and the HB fit on four ways!! The pic in the instructions shows it front on which is next to useless ... basically the flat edge faces towards the curved gun shield and the bit where the HB attach is at the bottom - may seem like mud but when you see one it will become clear!!
there are two feeder pipes from the external fuel drums to the vehicle, again from the instructions it looks like they are interchangeable - they arent!! the bottoms are chamfered so check which one is which
the little lasgun fits on the back of the turret for the command variant
apart from those few niggles it goes together well, sits nicely and is a brilliant kit, once assembled it looks good and is a beast!
