RE: moki 180 rpms
Wood is lighter than plastic. So the Menz would spool up quicker.
The APC is a good prop. I have the 20x10 APC wide on a Moki 210 and its a good prop. I bought this because I couldn't get the Bambula prop in the same size so I bought a prop grom the LHS.
I tried the APC 18x6 wide on the Moki 180 and this didn't work for me. Too much rpm not enough pull.
The Menz Ultra is also a good line of props. I like wood a lot so I stay away from plastic.
