In this video I'll show how i built an RC airboat for racing. The boat can travel on water, tile floor, and wet grass. It's powered by a 3S LiPo Battery (12V) turning a pair of counter-rotating brushlesss motors with 6" 3-bladed propellers. It's also equipped with a pump draw water from beneath the hull and shoot it out a nozzle at the front of the boat to knock over other racers.
I originally equipped the boat with an audio amplifier to play music as a gimmick, but i found that it added unneccesary weight and complexity, and couldn't be heard over the sound of the propellers, so I removed it.
The Hull is made from 3d printed sections that are glued together and smoothed out with body filler and epoxy resin. I hand-painted the parts instead of spray painting because I had a large supply of acrylic paints for arts and crafts.
Specifications (to the best of my knowledge):
Battery: 3S / 2200 mAh
Motors: 1400 kV
ESCs: 30A
Propeller: 6" / 3 blade / Pitch Unknown
Max. Current Draw: 22A
Water Cannon: 80 PSI / 4LPM / 4mm Nozzle
