It starts in April.
I did my first test last week.
I succeeded.
The speed of gps was about 25 kilometers.
It started with 55mm impeller waterjet type, but it had a thrust of about 20kg.
The water jet type has been changed to 120mm with a 5:1 deceleration.

What an interesting build. Thanks for sharing! Was that your esc that burned up? If so which model was it and how did you solve that problem?
