This project was created in partnership with Engineering Apparel; they make STEM themed clothing that actually looks stylish! Check out their new RC themed designs created exclusively for the release of this project here: https://engineering-apparel.com/electronics/rc/
This boat is a replacement for the first 3DRC Jet Boat, redesigned from the ground up using a completely different design ethos - this time the hull is completely sealed and uses a submerged motor and servo to mitigate any potential for leaks.
Features:
-Fully sealed hull
-Super simple construction
-Minimal extra hardware required
-Completely submersible
-Excellent fun to sail
This boat is super simple to assemble and all of the parts are easy to print even without a heated bed so it would make a great first foray into the world of 3D printed RC vehicles without compromising on fun.
Extras required:
4 self tapping screws (normally included with the servo)
4 M312mm bolts (3 for the jet, one for the hatch)
2 M2.56 bolts for mounting the motor
Waterproof 2 part epoxy for gluing hull parts together
Electronics:
5gr waterproof servo
1308 Brushless outrunner motor (I used this onehttps://hobbyking.com/en_us/multistar-viking-brushless-outrunner-drone-racing-motor-1308-4100kv-cw.htmlbut anything the same size will work)
Lipo pack (I used a 800mAh 2S pack)
Receiver
ESC
I recommend disassembling the receiver and ESC and coating the PCBs in epoxy for waterproofing, they shouldn't ever get wet but just in case the hatch leaks it's a good precaution to take.
A standard 5gr servo can be waterproofed by coating the outside in epoxy and installing on O-ring under the servo arm (see pictures)
