We offer the model of the rescue cruiser BERNHARD GRUBEN and its sister ships, completely assembled in our workshop and by hand, as well as the separate daughter boat as flexibly expandable basic models, so that you as a customer can choose the optional extensions and numerous upgrade options for these very beautiful models.
In this way, we achieve the highest possible level of individuality during construction - despite its origin in mass production, each model becomes a one-off! - and at the same time remain extremely flexible in terms of technical equipment!
Furthermore, the new base price for the model is significantly lower than that of the previous "concept model" and thus allows interested parties a much greater financial scope for special requests and optional extras!

The models of the BERNHARD GRUBEN and the daughter boat JOHANN FIDI are based on the construction sets from Graupner and have since undergone several improvements.
On request, the new base model can be equipped with 700-size electric motors instead of the originally planned 600-series. Of course, operation with modern brushless motors is also possible!
In addition, we of course also optionally install high-quality ball-bearing servos with metal or carbonite gears or servos according to your wishes.
In addition, a powerful transverse thruster can optionally be installed.

We offer a wide range of additional equipment for anyone interested in a model that is currently equipped with all possible additional equipment, such as etched parts, plotted lettering, perfect searchlights such as VIRGO and / or SEEMATZ, CNC-machined components, a complete RC system and much more.

After construction, you will receive a cleanly painted, functional model with all the functions and components you want, tested and, of course, test-driven.

On request including RC system & mobile daughter boat JOHANN FIDI, brushless drives, lighting, numerous LED headlights, fire extinguishing function (rotatable), bow thruster,
Multifunction sound and switching module and much more.
