Big Boy Feigao 580L

[Doug Smock]

First let me say that I would not have offered and marketed a motor for our boating community that would not accept some sort of water cooling.

The below picture was not going to be posted but I thought since some have had some questions I would post it. The reason for not posting is that the jacket is rather tight, but will fit with patience. I hope to have something along the lines of Feigao XL jacket/ Neu jackets in a month or so.

Why BLUE?? LOL

Keep up the good work Steven!!

Also, screws are removed easily with a quality 1.5mm driver. End bells come right off and can use these bearings

Thank You for that report.
It is intresting that they use the big 6mm bearings with the 5mm output shaft.
I like the Octura Flex Hex 5mm couplers more then the set screw type (6mm).

The shaft is 6mm with a optional 5mm output shaft.
I opted for them this way. Because of the more coupler options.

Good call on that one!

The cooling jacket you showed, is that a new jacket or the same KB45 jacket? Looks similar.

[Steven Vaccaro]

Thats a kb45 jacket. The OSE Feigao 580 L jacket will look similar to this.

Now that looks good.

would like to know from the "sport" pros if this motor would be a good candidate for a twin 53 or 58 inch cat using one of these hulls:

the gaser version run around 13,000 rpm using somewhere around a 65 to 70mm prop.

how could this be set up?

would be a twin drive LiPos

[TRUCKPULL]

For a hull that size you would want to run 8 to 10S
8S with a 850KV motor would be 25,000 RPM and smaller props.

I got my 580 6L today. Good bearings and balance. The phase wires are roughly 10ga. It looks great on the outside.

So I opened it up and it got better. The winding are evenly compressed with the coils nicely lined up (no wandering at all). Lots of copper in this motor.

The rotor is well balanced with the magnets mounted on an 8mm shaft that is turned down to 6mm for the bearings and again for the 5mm output shaft. Some how I don't think we have to worry about the shaft whipping at high RPM.

Now for some good weather to go testing. Oops, gotta build the boat first.

P.S. The KB45 water jacket fits fine.

The bearings are still the lesser expensive Asian ones. Some are better then others. But in the end a good set of bearings will be a thing to consider.

How many of these things sold? Does anyone have anything good or bad with experience yet? I would like to run one on 8S. It will be my first HV setup and in a 36" glass cat boat. Very light.

Any test results of the 580L???
