prop size

[kfowler]

can anyone tell what sort of load you would get going from a 60 x 42 to a 56 x 44

Rule of thumb for changing prop dia;

 

every inch of dia change should be matched with 2 inch inverse to the pitch.

 

For your decrease of dia by 4" you should be looking at increasing pitch to 50"

 

note your thrust efficiency will also drop around 5%

 

to answer the question directly, the load will be lower with the quoted smaller prop.
