Has anyone seen, or thought about building an efoil where the motor is located in the board, with a shaft running down the mast, and a gearbox and propeller all build into the fuselage?
With a folding propeller, it seems like this would have very little drag, like a glider.
Any thoughts on how to design this? The 90degree gearbox in the fuselage would have to be very compact.
My dad (the builder) and I thought about this some time ago.
90° gearboxes (right angle gearbox) are available for this, but it will be noisy as hell, and you will need to cool everything (even the motor)
I can’t get it. Do they move the motor up and down?
Can we think about a solution to move the motor up to the board, or even totally get it out of the water?
