Speed Boat RC (experimental)

3D model description

This is my very last try to make it really fast.
There is no way without a wide stern part.
The other problem is the high bow wave which sprays water into the boat. You can avoid it by spray rails. This is not unusual on real boats.
With both improvements it runs pretty well and I think it is fast enough - at least for me ;-)

3D printing settings

Printing
The best is, if you print it with spiral vase methode. Then you will get a neat surface without any noses from layer change.
The hull is 3.0 mm thick.
I printed with layer hight: 0.3 mm and width: 0.6 mm.
Anyway, you have to print it hollow with one perimeter otherwise it will not fit inside the interface part.

You can use the interface part from the motorboat enlarged.

Holes in support
The holes in the support to fasten the motor mount must be melted out by a slightly modified bowed soldering bolt ( as shown in the photograph)
Don't use a drill, it will damage the material.

The holes are not designed because holes are impossible to print in spiral vase mode.

I am constructing engineer for powerplants. Designing was allways my passion and I am glad, now as a pensioner, to have interesting challenges again.
I want to give thanks to the

Hi, I wanted to try your design but the front section seems to be missing from the files.
