When a manufacturer designates a propeller’s size, it is done by stating the diameter and pitch of the prop (Diameter x Pitch). The most important thing about the prop diameter isn’t the performance change, it’s whether it will fit your motor correctly! If the diameter is too big, the prop may hit your motor when it turns. This is one of the reasons Piranha may not recommend trying a certain blade size on your motor even if the blades size will fit your propeller hub. In most cases the propeller diameter will make a minor difference in the propeller’s performance. In cases where it is a significant concern, Piranha’s database has been programmed to account for this and select the best diameter available for the job
