This is my seccond version of the Tiger tank. In my first atempt I had lots of trouble when I tried to motorize the tracks. It was a problem of weight and size. The model was too big and had a lot of friction in the transmission for the old LEGO motors. As you could see in my first version, there was no problem in motorizing the turret. So I waited until the new powerful motors were avaliable.

All the decals are made with AUTOCAD and printed.
Also the new tracks were perfect in size and strength for my model. The old ones often broke even when they were used in the lighter and smaller Panzer IV.

The same transmission I used in the panzer IV had to be redesigned because of the weight of the new model. Fortunately the new Bulldozer set gave me all I needed in terms of strength and durability. I used the old 12 tooth gear bevel to make that 90║ turn in my first version, but it's behavior wasn't satisfactory at all. The new double 12 tooth bevel are capable of such a heavy work. In adition all the transmision had to be reinforced with vertical liftarms. And I have to thank LEGO« for the new XL power functions motors, without them the tank couldn't move. They are geared down a ratio of 1/3 to give more power to drive through obstacles and to make an impression of slow heavy vehicle as well.
The final version of the transmision.
I tried to recreate the early version of the Tiger ausf. E that used feifel air cleaners. I like the back design of this version with all those tubes and cylinders. The hull deck also includes the steel cables that were used to pull the tank if it broke down or got stucked in the mud. The turret design also was taken from an early design with smoke grenade launchers. The two upper hatches (commander cupola and loader hatch) can be opened.

the track guards can be seen.
Where to put the IR receptors was a main problem when the MOC design was in a final state. There wasn't much surface on hull's deck to place them. And more important they had to be placed somewhere where the infrared ray won't be interrupted. Finally the best place to locate them was in the front side, where the deck had less details and was more exposed.

Putting all the new power function motor system inside the tank was a hard work. The two XL motors power each track and the normal motors are used to traverse the turret through a technic turnplate and to move the 88mm canon.

The transmission for rotating the turret uses the Gear 24 Tooth Clutch to avoid damage when the traversing gun gets into an obstacle. This also permits manual rotating of the turret to reach the hidden on/off button of the batteries placed under the baggage bin of the turret.

The individual suspension system can be seen.
The suspenssion system is very simple. A mobile liftarm system holds every road wheel axle. This system is kept down by a rubber band that absobs the tension created when the tank moves through an obstacle.
