Hello everybody,
I’m building an Efoil from scratch. I plan to use a 3D printed core for shape, then reinforce it with carbon fiber. I have a rough CAD assembly for my plan so far. I’m looking for feedback on the design before I start the building process.
I’ve spent most of my time working on the mast-to-fuselage connection. The plan is to clamp the motor around the mast, then have the fuselage wrap around it and screw everything into the mast, and finally cover the fuselage with panels to maintain hydrodynamics. The bottom of the mast will be aluminum for the screws to tap into, and the screw holes in the fuselage will be filled with epoxy and redrilled.
Here is a picture of the clamp.
Right now, I’m working on the rear fuselage for the stab.
I want to mount it between the front of the motor and the prop guard, but this would leave me with a weird joint. I could connect this to the main fuselage and run it under the motor if need be, but I’m trying to avoid that for simplicity and hydrodynamics. Any suggestions?
I’m looking for any feedback on things to change before I get too far.
