MAN 3,5t

And the half of 7 is, ... 3.5,...

Thats why I take a Roco MAN 7.5to and cut it. This is one way to declare the way of assembling this car.

This was the test to place the components. I think red/yellow is the better colour.

The special thing of this car is the driveline. When a car have one commuting axle, it is like a three-point-bearing. So I build in two commuting axles and a balance lever.So the truck have a better road holding.


Here you see the driveline during the assembling time. The motor you can see here was too fast. Later I found a better one.

After finishing the car, I realize the to fast topspeed. The 1:30 gear is good for truckracing, not for truck trial.


Here you can see the balance lever.

I rebuild the drivline with a new motor and a 1:100 gearbox. So the roadholding and the offroad feeling was much better. I also build in a microcontoler. One time as the speedcontroler. Additional the controler also maintenance the lights.


The long distance lights maybee a little bit hurting if you look inside.

This truck was a participant of a contest. It was to solve a problem by using the Texas Instrument microprocessor MSP430.



Here you see the microrocessor. The reciver is hidden in the hull.

specials:
- two balance axles
- microprocessor
- standby mode
- electronic two gear shift
- lights
- building in: Jan 2001, rebuilding Nov 2001
