I have recently reconfigured its drive system to use slower gear ratio, and guess what, it is not slower at all. But hell does it have a lot of power... It pushes large boxes and will try to climb walls to the point of being almost upright.
I do not really like lego models with shooting function, because it is always a laughable "plop" after which a tiny little thing flies a meter or so and thats all.
Believe me that whole desk shakes when the Land Raider is moving and it tends to leave deep track marks on any soft surface. It is still a toy, but with 3,5kgs of weight and enough power to rotate the tracks even if it lacks grip to move, it realy conveys a sense of power - especially considering the noise it makes with rather clanky mechanics and four super-powerful (for LEGO world ) XL motors.
I have a movie somewhere where the tank was literally crushing an ork settlement and now with better gearing I believe it could do it way more efficiently. Unless it again sucks in entire blanket under it like last time
Compared to this, shooting function just feels... lame.
