RC Mercedes Citaro . Hi everyone! This is my third tiny RC with two M motors, an IR receiver, a battery box and a working and realistic articulated part! It's 47 stud or 37,5 cm long, only 6 stud wide and contains approximately 800 pieces! Hope you like it! :) .
It shows us the inside, how the motors work, you can see the bus in action and the articulated part during operation!
There are some photos here, they show the whole bus:
Unfortunately there is no place for passengers and driver.
You can see a picture of the real bus here!
Driving and steering
Steering works very well! The bus has no problems in the tight bends of the lego road plates. The chance of the oversteering is still alive, but not too dangerous! If you steer too much, the windows stop the gear rack, the motor rises the roof a little together with some gears, a split grows in the transmission, so the motor can spin freely. You can repair it easily: push the roof back!
The bus is full of interesting building techniques. The front and the back contains a lot of upside-down pieces and the doors are vertical.
The articulated part
It was the most difficult part of the building, so I'm very proud of it! :) First I tried to use technic 2 long liftarms, but they didn't move realistically. They were very ugly in the bends and in straight, too. I wanted the parts of this part to move smoothly and to stay in the middle. Finally I put into the first part of the bus two pneumatic tubes by two of these elements. At the back the tubes are held by two technic hole. The distance between the two parts of the bus is changing, so the tubes have to slide a little.
This is a part of the articulated part. You can see the spaces of the tubes. The cabel of the receiver goes to the battery box through the 2X3 whole, too.
On the bottomview you can see the cardan joint, which holds the weight of the back, it pulls the back part and if you reverse, it helps you to drive. (the tubes are very flexible, so they are unpredictable, too :)
If you like my bus and you want to play with it at home, please support on Lego Ideas. You can find my other two tiny RCs here and here! Supporting takes only one minute!
Merry Christmas and Happy New Year!!! :)
