Cool idea to use windsurer as the motor platform.!!
Can you provide some detail on the “plate” that holds battery and electronics?

Congratulations. The motorss are wide apart, it should go well in a straight line, but active turns are only possible when you release the gas, right?
!thanks, pivot is right between the motors, with two little fins, impossible to turn without the help of hybrid control of this remote. I soon provide a technical video, so much to say, so many thing to improve too !

I had 2 of this kind of unit booster on an old parrot disco drone. It works but not really legal. It heat a lot on certain design and you must put it on tx and rx side to have great range. You will have a lot of work for waterproofing. As a first try I will put one unit on rx side only because it is easier but frankly, bRemote is the the way to go on my opinion. If there is a failure, you can swim but not easy with all this !
As an old windsurfer, I love your idea ! Congrats and it seems to work well!

Inside the box, ES400 is scooter battery, very easy to find 3y ago in my city. It should be second hand market somewhere, ESC for charging is working, need to open on the side to find the direct + and - to get full power.
right now, I need to improve these banana connectors, with bigger bananas, they melt the solder…
ESC are set to 80A and 200000ERPM
everything comes apart easily, very practical when you don’t have much space.
I just found a board in a trash can, AHD !
