BIG JETTY - 1/6 SCALE - HAVE-IT-ALL - TWIN-ENGINE RIVER JET BOAT - HPW40 INCL.

Big Is Beautiful!

Our twin-engine river jet boat BIG JETTY in 1/6 scale was developed according to this motto.

The model is powered by two 40 mm HPW40 jet drives with an attached 2.2 kW brushless motor on 3-6S LiPos. You can also install your M-Jet 30 or M-Jet 35 . There are separate hull print files for these pumps also as part of the files package.

The print data includes all the necessary data for printing the hull, HPW40 jet drive, deck, cabin, roof, railing and add-on parts.

BIG JETTY is one of the largest and most comprehensive RC boats for self-printing on the market.

The data package (STL, STEP, 3mf) consists of 253 different print parts, with a total of 670 components to be printed. The resulting level of detail sets new standards.

BIG JETTY impresses with its sheer size and high functionality (sliding windows, sliding door, folding deck, folding ladder, lighting, etc.).

It therefore places high demands on the builder both in terms of assembly and driving.

In addition to the print data (STL + 3mf), the data package contains detailed, illustrated assembly instructions (122 pages) as well as illustrated printing instructions (22 pages). A complete parts list is also included as an Excel document. This contains a list of all required print parts, as well as a detailed description of the required add-on parts (incl. recommended motor, ESC, servo, etc.).

The model can be printed in PLA tough, PETG or ABS/ASA. The double-walled hull gives the boat great stability.

For demanding trips, we strongly recommend printing in ABS/ASA. We have had the best experiences with Polymaker PolyLite ASA and ABS.
