So as you well know, i finally have it in my possession: the graupner B28. After waiting more than a year, it's finally there. And at this moment we already began with the building process.

Here you see how it is going to be.

 

The beginning of a new paint job.

 

With the good building plans that Graupner included with this model, it's easy to build the model. It took me just half a day to install all the hardware on the hull.

 

Isn't it a beauty?

 

Here you see that the motor is glued in. We made a carbon motor plate which will hold the motor in place when all that power is unleashed.

 

Painting the crew.

 

Almost finished. I wonder how i shell name the crew?

 

Cockpit canopy fitted in place with small screws to protect the crew from the elements.

 

Inside view with motor, controller and electronics installed.

After the first test run...

Since the original setup didn't function (the rudder was too flexible and the axle couldn't withstand the power of the motor), a new rudder with water pickup and a new strut were installed. Not visible: a stronger flex axle.

 

Rear view of the stern.

 

Inside view: the battery mounting plate was torn off, so it was refitted and reinforced with glass cloth.

 

Battery packs in place.

 

2 x 15 cells, totalling 30.

 

Schönes Fahrbild: 72.6 km/h.

 

Nice rooster tail; not bad for a second test run.

Here she goes!!

We're still searching for an optimal solution and are trying to improve this boat even further.
I'll keep you up to date on this new project.
