Default RE: another beginner question - prop identification
GIVEN THE SAME RPM (very important):

1. Larger diameter/less pitch will produce more thrust, less top speed.
2. Smaller diameter/more pitch will produce more top speed, less thrust.

Case #1 is like low gear in a car. It accelerates quickly, but doesn't go very fast.
Case #2 is like high gear in a car. Lots of speed, but it takes a while to get up there.
