honestly reading the product description it would fry WAY before the motor even moved.
It's more like a Solder it yourself BEC to control servos, seeing it can only take in 2Amps of power. At most it can put out 1.5 amps at 12 volts which even 1/24th models pull.
And seeing its a voltage regulator it would only make the voltage constant (aka no speed control) so you might as well just use a switch
Note here are the applications as stated on the site
Powering 5 V or 3.3 V systems from lower-voltage batteries
Powering 5 V subsystems (e.g. sensors) in lower-voltage (e.g. 3.3 V) systems
Achieving consistent actuator operation when powered by fluctuating batteries
Powering high-brightness LEDs or a large number of LEDs in series
