Now I understand the physical idea of motor building, I just don't fully comprehend the whole theory behind it. I am and always have been horrible at math and everything involving numbers. Maybe that is part of the reason I will never understand how people come up with the correct lift, degrees, clearance, and everything else involved with building a high performance motor. I mean, I read a Vizard article and it feels like my heads going to explode. Maybe I'll get it one day, but for now it's all going to that same place as other things I don't understand, like the meaning of life, long division, and how to get chicks.
