3D Printed RC Brushless Speed Boat 

This boat isn't my design, but was assembled by me with Rc airplane parts I already had laying around. I bought a motor to drive shaft adapter, a propeller and a drive shaft for this build.
I used a 40 Amp ESC, a 2212 2400kv motor and a 3 cell battery. The boat was overpowered and I couldn't push the throttle over 50%.
