T-72


As a child I always wanted a model of the Russian T-72, so I decided to create a version of the tank out of LEGO bricks.  As is often the case, the model started with wheels.  This determined the scale, and from there, I was able to determine the rest of the tank dimensions.  This gave me very little room for all the functions of the tank.

Model of the popular Russian T-72. View the full gallery here.

The tank includes independent suspension on all 12 of the drive wheels.  6 are suspended with 6.5 length shock absorbers, 4 are suspended with rubber connectors, and the final two are not suspended, but move freely with the track.  The tracks are driven from the rear by two longitudinally mounted PF M motors.   These are connected 1:1, through double bevel gears to the 24z sprockets.  The battery box is place in the front of the tank, with the IR receivers placed over the drive motors.  The final PF M is mounted vertically in the turntable, to rotate the turret.  It could use another reduction, as the rotation is a little quick as you can see below.

I was pleased with the way this model turned out.  While the functions work alright, the aesthetics of the tank represented the original well.
