Are there any other performance advantages to running a diode, other than keeping your speed control from letting the smoke out? I keep hearing that they aren't necessary in stock or 19 turn brushed motors, just for mod.
What else does the diode do? Does it restrict power at all? If so, I won't bother with it for stock. Some believe that it stores power somehow and gives you more punch. I don't see much difference with or without.
Help me understand.
