Efficient small props.
I am building a 36" Martin Mars 4 engined flying boat. It will have 4 Hyperion 12 mm diameter inrunners, KV of 4100.
Mfgr. tested with a GWS 3 x 2 prop. It turned 22,560 rpm. It pulled 3.7A @ 7.3 V = 27 watts. WOT is calculated @ 42 mph.
Are there more efficient props made in the 3" size ?

RE: Efficient small props.
Not sure what you are trying to acomplish??? Can you post some pics of your project? Look at APC-E props they are some of the most effecient props out there.
