Ok guys, capacitors? mine came with two ceramic caps and a diode, I understand why I need the diode, but why should I install the capacitors?? (i was going to tell you what kind of a motor I have but I always forget

) all I know that it's a Speed PRO by Trinity it also said Kobal on the package
ok ok so I'm still learning, motor, batteries etc.

it's funny because I design electronic boards for living
