Oops : 16 x 10 (not 10 x 16) Thrust calculator http://members.jcom.home.ne.jp/4223215501/staticthrust.htm Plugging diameter 16" pitch 10" 2500 rpm and 100% efficiency gives 55W = 0.07HP
I'm nor sure what the efficiency is for converting electrical input to motor shaft output. 80-90% ? It does go up very rapidly with RPM 2000 : 25W 2500 : 50W 3000 : 85W 3500 : 135W 4000 : 202W
