The Feigao motor has arrived. The 580L motors look rather impressive. I will have some pictures and sales info by the end of today.

580l??? Is that like the size of a 600 brushed motor?

580L? A quick search show it to be 45x50 in size.
"Ferrous loss free brushless motor, 6 poles. World first 580L size ferrous loss free BL motor."
6-pole motor should be nice in a 45mm diameter.
Also, the diameter larger requires a larger water jacket. Any plans of one, or will the KB45 heatsink work?
My prop hasn't been wet in a while.
Never mind. I looked it up. It's a 45mm can. Should be a torque monster!!!!!

Steven, does it appear to be of better quality than the KB45 series

Steven,
I take it that this motor uses the same mounting bolt pattern as a say the KB45.
My prop hasn't been wet in a while.
Steven, if I removed what look like allen head screws on one end, would the Kb45 water jacket fit?
Or would that be a dumb move?

I'm going to have to get one of those to punish, er, eh, I mean check out. LOL

I have attached a FeCalc data file with the Feigao 580 motors added.

M1 Supercat - Neu 1527 1Y, 8s / Mean Machine- Feigao 580, 8s, 120 HV esc
Mean Machine - Feigao 540 14XL, 8s, 100 amp HV esc, X537/3
you finally got it Steven!
if needed, the rotor can be replaced.
Took longer than I liked also.
I just received the 580 6L winds also. Should make a good 4s motor.

Added the 580 6L motor to the FeCalc data file.

whats the advantage of using the new 580 l as opposed to the 540 xl 8 ? i am building an mm hull and want to get the best for the buc. so when i pick a motor (in my budget zone) i awant to make the right choice. will a hydra 120 esc be good enough for the 580 or not? still a newbie so now the watt thing has me a bit confused. 8xl, 1000 watt max 580 l, 1400 to 1800 max. batteries determine watts being applied or what? really want to understand
volts x amps = watts. You know volts from the batteries you use. The amount of amps is determined by the motor and load(prop size). The bigger the prop, the more load. So a motor can be run at varying loads. For example I have run the same 540xl motor at 40amp to 80 amps, depending on what I was trying to accomplish.
The 580L has a weight advantage over the 540XL. The heavier the motor, the more torque is will have.
These are all general thoughts. There are very thick book discussing the finer details that spin my head.

The 580 has bigger can diameter and more or less same rotor lengh than the 540XL, so it will have more torque
thanks guys you answered my question, so an 8xl with a max of 83amps and 7.4 volts would yeild 614 watts as compaired to a 580 -8 with a max of 91 amps and 7.4 volts yeilding 637 amps, so the 580 can be run using 2 4s in series to get 14.8 x 93max amps = 1346 watts still under the min 1400 to 1800 watt min/max . 0r should the 4s be run parallel to keep the volt down. does what im saying make sense or am i just a little slow lol

Two 4S in series will give 2x4x3.7=29.6V!!!... Assuming you talk about 4S lipo's with nominal voltage per cell of 3.7V
I guess you ment two 4S in parallel to double available max amp from batteries?
sorry, yes i was using nimh volts so 2-4s 3300 in parallel would give me how many watts if the 580 8 has a 91 amp max
Sewerpit, do not get too concerned with the maths, as it all goes out the window with the prop you choose and the setup. For a hydro 120 I would select a 9XL for 4S a 12XL for 5s. as a max
Conservative...yes...dependant on your prop, boat length,width and style. Those are the factors that count. Your mean machine will not benefit from this new motor...My 2 cents
Douggie
4S lipo's (14.8V) the 580-8L will give you 4x3.7x91=1346Watts
thanks to both of you for your simple answer, makes it sooo much easier for me. 9xl it is . will keep you all posted once my build begins ill get to proper prop when that time comes
Last thing, I'm sure Douggie and others will agree, you cannot really compare a 540-8XL to a 580-8L...
first the weight, a 540-8XL will just fit, for example, in a 29" mono, while she would look like a submarine with the 580-8L!
second the torque, the 580-8L will have something like 30% extra torque compared to the 540-8XL, it will be able to spin a much bigger prop and move a much bigger hull!
this is why this site is so good, great information not only saves newbies like myself money, it makes the whole boating thing very enjoyable ,,thanks again to all of you i hope i can provide someone some help too one day
Good job getting this motor, Steve. I run a Lehner 2250 in my P mono, which is only 1 oz heavier than this Feigao.
I bet this motor, X445 prop, a CC120 or ETTI 150, Titan 33 or DF 33 will run just fine on a 1P setup and handle a 1 mi race heat.
OK, I think I'm going to have to wrap a new P hydro around the 6 turn.
