What makes an arrow fly true?

An arrow flies true due to a combination of factors including its straightness, proper fletching, and balanced weight distribution. The fletching stabilizes the arrow's flight by creating rotational forces that help it maintain a straight trajectory. Additionally, the nocking point alignment and the bow's release technique also contribute to ensuring that the arrow travels accurately towards its target. Together, these elements ensure that the arrow achieves optimal aerodynamic performance and minimizes any deviation in flight.
