First Run of 3D Printed RC Jetboat: Unleashing the MJet Supersprint!

The fully 3D printed MJet Supersprint RC jetboat is truly insane. I didn't dare to pull the throttle for longer than a second just yet.. Stay tuned, rougher waters coming up.

The jetboat is powered by a 1500kv 3680 rocketrc motor and a 70A flycolor ESC. Besides electronics almost everything is 3D printed, even the propellor! Despite a bit of leakage from the metal motor cooling jacket, the performance is crazy, I was a bit worried the motor would be too big but everything seems to be running well so far. I used a 1100mah CNHL 6s 100c drone lipo, but I'm planning to upgrade to a bigger battery for longer runtime. 1500mah should be fine for about 7 to 10 minutes of jetboating.

Special thanks to Štěpán Müller, the designer of the incredible pump and boat, for making this experience possible, you can find the plans on cgtrader by searching for mjet supersprint.
