Yamato Battleship 1/350 RC props test

Propellers test. Central motors are wired to the ESC. Side motors are wired directly to the battery pack (the ESC can handle one or two motors, it's very inadvisable to connect 3 or more motors) and turned on/off by a servo-switch (a servo linked to a 2-ways switch). Of course central motors thrust can be modulated, whereas side motors are just on/off, not modulated.
