Welcome friends and neighbors,
there was a little bit work, to make the "COURIER" steamboat a satisfaying live steam model. The presentation of the engine was rather different, when the boat was swimming. In the past, the long and narrow hull has showed a tendence to heel - I tried to stop this. The solution seems simply: A bore hole of 10 mm diameter at the top of the wheelhouses - makes the air of the turning wheels escaping, the hull lies stable in water.
I even turned the engine 180? degrees because the preference of running direction. The gear reduction of 1,2 : 2 wasn`t enough, the gear reduction now is 2 : 1. I don`t altered the rigid and small (100 mm diameter) paddlewheels, they are in scale.
Today the test run in the tank seems satisfaying - to avoide cavitation, it?s best to start the engine in a slowly manner. With the gear reduction, the torque will be good to whirl the water, when the model is driving faster.
I can say: This engine made of the "ROCKET" Loco is far more suitable than the first two engines!
