Hi All
EDIT - 23/01/2018 - I have now also included a 3d printable basic hull. There is no jet drive cut out so you would need to print and cut out your own drive to fit. With the jet drive creator's permission I may also include a hull with the main body of the drive already incorporated.
Based on this fantastic Jet Drive design, I decided to build a little twin jet drive jet boat based on two of these drives printed at 50% and powered by two 370 type brushed motors.

This is very much a 'kit' and will require the builder to fabricate some parts, glue on sheeting or planking etc. I.e. it is an intermediate level kit.
PLEASE SEE DXF FILES IN 'THING FILES' FOR THE LASER CUTTING FILES FOR THE HULL, DECKS AND WINDOW GLASS.
Parts required will consist of:
Wood-
3mm Laser plywood
0.8mm Laser plywood
2mm Square balsa or softwood stringers
Plastic-
1.5mm Acrylic or similar sheet for windows
3d Printed parts-
2x the jet drive units liked above printed at 50%
Windows (still to be finished)
Door
Cabin roof
Adapter plates (2x - same file mirrored) to fill the gap between jet pump and hull
Hardware-
2x 300 sized (I used 370) brushed motors or equiv brushless
2mm stainless steel shaft
Suitable bushes for the jet pumps
Piano wire for linkages
Suitable Lipo cell (I used 2s 1300mah)
RX, ESC and Servo
