Reaction Wheel RC Arduino Boat with Fin (No Magnets)

With the Bambu Lab A1 mini I designed in FreeCad and 3D printed an 84 gram reaction wheel that is mounted on a continuous 360 degree servo.

When the reaction wheel turns clockwise the boat turns in the opposite directing and when the reaction wheel turns counter clockwise the boat turns the other way. When the boat turns the fin pushes it through the water reaching a top speed of about 90 inches per minute.

An Arduino controls the servo with a radio control circuit.
It's crude but it works.

Stay tuned:)
