Thanks for all the info on the PC9 guys, very much appreciated.
NOW!!!
Time to put your thinking caps on
If I want to replace a 2 blade propeller with a 3 blade propeller, lets say for arguments sake a 2 blade 12" x 6".
Theoretically I am increasing the load on the motor by adding the extra blade.
Or am I?
Am I just sharing the same load over a larger area?
1. Do I reduce the pitch by third or a half? ie: 12 x 4 or 12 x 3
2. Do I reduce the diameter by a third or a half? ie: 9 x 6 or 6 x 6
3. Do you do both? (that doesnt make sense to me)
4. Or do I do nothing?
5. Or is there a super mathematical equation the does the Diameter and pitch conversion for you?
I would like to know without having to buy a heap of props and doing the load tests.
Hope that has your brains in overdrive.
3 blade props just make more sense (The balance must be better)
