Materials and methods

Materials and methods
Needed material

- about 400g of material of your choice (350g hull / + Jetpump and Impeller) Pla or Petg would be best
- 0.2 - 0.25 layerheight recommended. 20% infill "honeycomb"
- print at least with 2 perimeters

Once you printed all parts, you should glue the hull together, using some superglue.

A couple of m3 x6mm screws should lock the pump/nozzle in place
A m2.5 x5 mm screw (only for my motor. Just ask if you have any questions!)

Electronics:

1900 - 2200KV brushless inrunner motor the one I used: https://www.rc-raceboats-shop.de/lng/en/motoren/seriousrc-4-pol-motoren/seriousrc-28mm-motoren/src28606d-2100upmv.html?type=N&language=en

50 - 80 amps brushless ESC, depending on KV of the motor the one I would recommend: https://hobbyking.com/de_de/hobbyking-red-brick-2-7s-70a-esc-v2.html?queryID=9a5da3c65ca76e65c84c4a6f5c9d44b3&objectID=48606&indexName=hbk_live_magento_de_de_products

a 2s - 6s Lipo up to 2200mah, 2 would be best to not have an overweight on one side!

a 9g servo.
and of course a transmitter and a receiver

Bushings:

as the boat is really small, it only uses bushings wit an ID of 3mm OD of 4.5 and a length of 5mm
These are mine: https://www.igus.com/product/58

As rod, I advise a 3mm x 200mm Stainless Steel rod
To fit the impeller, you have to file a flat spot at the end of the rod and try to slide the Impeller on. It should have a thight fit.

As lid, there is no printable option yet. It`s just a selfmade lid of 2mm acrylic glass.
