Interesting! great find
Do you think a 4092 1390kv would be ok to use with a 6s setup in a FC 32" River Cat
would it give me considerable more power than a 4074 1400kv
It says it pulls 120A at 25v so would an etti 150A hold up or would that be on the border line to


might have to get a T180or one of Bens 300A ESCS
what size prop do you think would be suitable x447? and any one guess what kind of speed if set up right

It says it pulls 120A at 25v so would an etti 150A hold up or would that be on the border line to

it say that RECCOMENDED MAX is 120 amp and 25V it can and wil pull ALOT more then that if over propped

It is a common misconception that the "amp rating" a manufacturer gives for his motor is the actual amp draw. It is not. The rating is usually the maximum amperage the motor maker thinks is safe. The Leopard motor above can be propped to draw 300 amps if the packs will deliver it. Prop size, boat size, and boat trim all effect the amp draw of a motor.

Since no one has a 4092 motor, no one can comment yet other than guessing. If it is like the Leopards I've worked with it will safely handle 120 amps although it will probably get hot. It 'should' spin a larger prop than the 4074 will, but since power is directly related to amp draw, I doubt that you'd see much difference with your ESC. The 32" cats do not like props much over 50 mm in diameter so the ability to spin a larger prop is not really an advantage. If you used the x447 prop with good cells in a well setup 4074-powered cat you are looking at speeds in the low 50s.

Thanks Jay
understood!
I would expect this is were data logger comes in useful. take away any guess work of amp draw and prop sizing

I think there's something wrong specification ,maximum speed just 35k only ? max amps and the max volt just like 3000w motor .how to output 4200w ?

[video200]

i beleve the max volt and max amp are max continuous amp and volts and the max watt is burst. atleast that is how leopard normaly post its motors.
like this 4074 here on OSE "Watts: 1500 with Over 2000 Burst." ( http://www.offshoreelectrics.com/pro...o-4074&cat=148 )
