Ever wonder what it’s like to ride the world’s biggest 3D-printed hydrofoil? If so, then Daniel Riley of RCTestFlight has just the video series for you. The story began when he 3D-printed a miniature hydrofoil to test and the rest is history.
Scaling the miniature model up to a life-sized version wasn’t as easy as simply printing larger parts. First, everything had to be designed in Onshape CAD software before everything could be printed. Carbon fiber booms were used to connect horizontal stabilizer to the main wing. After countless hours of work, lots of electronics (servos, motors, etc.), and some failures, Riley ended up with a 3D-printed hydrofoil that he could actually ride, all controlled with a gamepad.

A little tip from an old aircraft mechanic: If you want the wings to be streamlined, you only need to attach the servos for the wing above the waterline. Simply run them down the legs with a pull/push rod, then lead them to a rotating rod that runs through the wing and then to the flaps again with a pull/push rod,” said one commenter.
