To answer your second question, static thrust, as measured on the ground, means next to nothing. It has been found that if you prop for the highest static thrust on the ground your airplane will be a dog in the air. As soon as your plane starts moving forward the thrust it's prop produces is not the same as when the plane is sitting still. You could consider yourself being on the "backside" of the thrust curve. What you need to prop for is maximum thrust at your slowest speed on the race course, which is generally in the middle of a turn. Hard to do without a datalink to your plane!
