Hello I am Kevin and I am building a jet drive for my windsurfing board.
I use the following components:
- Flier Boat 400A ESC
- SSS56114 / 500KV engine (I think I will switch to the 790KV engine)
- 2x 6S 4000mAh Lipo from my helicopter
- Capacitor bank with 10x Low ESR 330mF (to reduce ripple voltage and safe the ESC)
- DC Hall sensor Ampere meter
Many components I have printed with my Anycubic with PLA+ and PETG.
The first results are good: about 12Kg thrust, with 6S Lipo and 60A current consumption. Motor and ESC stays cool. But will later be water cooled. There is still potential for optimization. My next test will be with 12S Lipo, but the better option is probably to use the SSS56114 / 790 with 6S.
Currently I have the problem that the o-rings get broken when I push the drive into the aluminium tube, because they are pushed over the hole in the aluminium tube.
How did you solve this? Is the pressure for the O-Rings possibly too high?
