RC Boat Introduction

I have decided to start on a project to design, fabricate and test a fully functional remote controlled (RC) boat inspired by a 1940’s Chris-Craft. The goal is to be able to remain stable and running for approximately 10 – 15 minutes on a battery pack. This boat will be designed as a semi-displacement hull which will allow it to operate more smoothly at slower speeds. The boat will be engineered with stability and maneuverability in mind. This being said, the boat will be a small scale model of an American classic that can be enjoyed by people of any age, whether it’s enjoyed in a pool, lake or ocean. The motor and other electrical components will be salvaged and modified from a previous RC boat/cars. The hull will be 3D-printed from PLA. Its propulsion will be a single electric motor and propeller that will be directed by a large rudder at the stern. The propeller shaft will be fitted with two small ceramic bearings to insure minimal friction and stress on the electric motor.

 

Goals:

 

  • Operational by a single person
  • 10 – 15 minute (minimum) battery life
  • Stability in minimal seas
  • Maneuverability
  • Corrosion resistant
  • Approximate top speed of 5 mph

 

Budget:

 

  • Electric Motor (In House)
  • Hull (PLA) In House ($10)
  • Receiver/transmitter (In House)
  • Strut and rudder $25
  • Propeller $20
  • Drive shaft $8
  • Bearings (In House)
  • Radio (In House)
  • Misc. $30

 

Total $83

 

Timeline:

 

June: Research, preliminary 3D-CAD design development, 3D printing.

 

July (18th – 31st): Finalize design, 3D printing, order parts.

 

August (1st – 10th): Assemble electrical and mechanical components, trouble shooting, testing.

 

August (13th – 17th): Final testing and finishing.
