rc jet boat

this rc model jet boat uses a standard brushless outrunner motor to drive the propeller. initially i chose a t-motor 1806 2300kv but this motor got quite warm. this new design can be used with a larger 2205 2500kv motor that can handle much larger currents.

the assembly process can be seen in the following video:

here's a video of the boat with a tiny 1806 2300kv motor:
