Hello people

Here is the final entry topic for the Eurobricks Contest "To Sail the Technic sea".
It is a red Lego Technic  speedboat, which can swim.
The two bodies of the Lego City 7244 speedboat were the base  and I build a Lego Technic connection between them.
Here it is:
Front view

Side view

Propellor

Bottom ( attached two airtanks so that it lies a bit higher in the water)


The functions
1 M Motor for rotating the propellor
1 M Motor for steering
It is RC controlled via 1 IR reciever

Here are some pictures to see the inside of the boat:







And here is a short video to see it in action



Hope you like it^^

But she isn't speed :( Do you tried to improve drive? Gears and lift reduce the efficiency of propeller unfortunetly

The speed is impaired by your choice of this tiny, inefficient propeller. You should try this: http://www.bricklink...Item.asp?P=2952
