What is the difference between three arrows and two arrows?

The stability is poor, and the two arrows are more susceptible to the influence of the wind during flight, which appears without the lateral deviation of feathers. Three arrows are more stable, and the influence of wind can be almost ignored under the action of high pounds. The use of rotating feathers basically depends on the stability and dispersion deviation of the shooter, but the wind resistance is large, and the range and arrow speed are affected.
