Remote Control Boat

Thomas Frederick Bergman

The project is a dual hull powerboat that is remotely controlled. It is designed to be a recreational activity for its user. The boat is two feet long and is powered by two electric motors. It has a mechanical speed control out of a Tamiya Midnight Pumpkin. The power plants are from electric remote control racing cars. The boat is equipped with a dual rudder system. Another design considered was to have a single prop mounted in the center of the boat. There was also debate whether to have a dual rudder system or to have a single rudder and where to put the dual rudder system if dual was decided to be desirable. Along with design ideas was discussion with what to fabricate the hull out of. The idea of aluminum, or of fiberglass seemed to be the most feasible. Fiberglass was decided on because it was more flexible and did not require any welding skills. The original mold for the fiberglass was made out of Styrofoam and ended up melting due to the fumes give off by the hardening fiberglass. This put the project behind schedule. Next wood was purchased and screwed together to form a frame and aluminum screen was stapled to the outside of that. Then the fiberglass was laid across the screen. The initial intention of the design was to have a single gas powered engine. That option ended up being very costly and would have taken much more time. The workers at Hobby World in Grand Rapids were helpful in suggesting that using the brass tubing and brass rod for the drive shaft. For a connection they suggested some common fuel tubing because it would easily slide over both the engine shaft and the drive shaft and would act as an U-joint between the two. After a little bit of soldering to add another engine connection the project was placed in the hull and screwed together.
