Here is a 3D printed RC 3-point hydroplane. For assembly of the hull, epoxy the two hull pieces together, and put wood meat skewers through the cylinders for added strength. Epoxy was used for all things that are glued. The rudder servo and receiver was pulled off of a Traxxas Stampede. The rudder push-rod was pulled from an old plane. Holes for the prop shaft and rudder push-rod were hand drilled. Be sure to use loc-tite on the universal joint screws. The motor was attached to the motor mount with a 14.5 mm wide hose clamp.

Hull length: 14.5 inches Beam: 8.5 inches Top Speed: TBD
