The miniature motors and servos, lights, smoke, sound, that go into some of the RC trains and tanks are amazing. There is this Tamiya 1/16 M1A2 Abraham RC tank where turret and gun can maintain their direction and elevation as vehicle turns, smoke machine and reproduces start up, acceleration and shutdown sound sequence has per the real mccoy, recorded from the actual tank. Gun recoils and tank kickback, lights, etc. Still you have photo-etched metal parts and nothing is sacrificed in terms of details.
There is a set of videos by an ex American military serviceman who worked on the actual tank before so he has intimate knowledge of the details. He applause the accuracy of the Tamiya and passionately painted the inside white, just like the real thing. Kudos to him.
Here is the first unboxing video and he has a set of build videos as well.
