Looking to the tune page I calculate the resistor to use : 1 ohm // 1 ohm // 10 ohm for a 0,47 ohm so in theory if I find a resistor of 0,47 ohm can I use it directly instead of the parallel of resistors? How to calculate the watt of this resistor? Last thing: do you think is better to change the transistor or other component to drive my motor ? Thanks in advance!
