More Poles results in more low-rpm torque, not more power. IMO, 2 poles are better for top speed aspirations, as they hold power higher into the rpms vs the higher pole motors, and have a broad efficiency range. Higher pole motors tend to have more low end power and narrower efficiency range. 4 pole motors are pretty ideal for most RC applications and work well for top speed, though I would give the edge to a 2 pole motor(for top speed).
