I have the upper picture and will be finishing the engine hopefully this week and mounting the hpi. I have the battery, silicon rectifier and two wire trail tech. I am planning on what I first said but wanted to check with you guys if it makes sense .
From what I sort of am understanding is that with only one hot wire the output is by definition half wave rectification and is therefore so close to dc in its characteristics that one can dispense with the silicon rectifier and just use a volt reg with perhaps an energy sink that could simply be a capacitor and not a battery. Is this true?
