Hey!!
What is the rule of thumb for going from a two bladed prop to a three bladed prop??
How about a two bladed prop to a four bladed prop. whats rules to doing that??
Any help would be great!!
Keeping the same pitch:
2 blade to 3 blade: Multiply the 2 blade diameter by 0.9.
2 blade to 4 blade: Multiply the 2 blade diameter by 0.8.
