Based on bronze propellers of 33% DAR.

Please note these calculations are APPROXIMATE only, and useful mainly for carriage / shipping purposes or for dynamic balancing costs estimation.

Formula;

• 0.00241 x (Prop dia in inches raised to the power of 3.05) for 3 blade prop.
• 0.00323 x (Prop dia in inches raised to the power of 3.05) for 4 blade prop.

For example if diameter is 14 inches weight of 2 and 4 blade props is 8 and 10 lbs respectively. Please bear in mind that this formula is a very rough approximation only.
