My parent's front yard will flood with up to 4 inches of water in heavy rain. I've told my dad for years that it would be a lot of fun to run an RC boat when this happens. I decided to make one for him for father's day. I decided on an airboat to avoid the prop getting fowled in debris or weeds and to allow if possible for it to slide across the grass from his front door to the temporary lake.
To complete you will need:
5" propeller (I used a 5045x3)
Motor (I used a 2204-2300 multi-rotor motor)
ESC (I used a 20amp multi-rotor esc made bidirectional with blheli)
RX of your choice
RC car body pins
Battery (I used 3s 1300mah)
Glue for plastic components
At least the bottom 3 pieces of the hull need to be printed at 100% infill to make them water tight. The other components can be done however you'd like, I want with 50% for most.
All of the parts with holes are intended to be screwed together with 3mm screws. The hull is intended to be glued together.
Painting the hull will help seal potential leaks and make it more smooth.
Low temp hot glue can be used to seal the wiring holes in the radio box.
