Getting intimate with the Feigao 580L (and MetalMan's hands)
 

Nobody here seems to have purchased one of these, I've only seen speculation :neutral:
So I bought one because my XLB killed the KB-45 10XL that was in there (shredded the windings, the rotor was still intact). The Feigao 580L I ordered is the 12L, with a kv of 1051. Now for the good stuff!

Looks like it has a 8mm shaft where the rotor mounts, which is turned down to 6mm for the bearings (beefy bearings!), and then the output shaft is 5mm with a nice flat spot. The windings on this motor seem to be a lot neater than on the Feigao 540 motors, which is nice. Also, it's hard to see in the pics but there is a steel cylinder between the windings and the can. This steel ring is what's causing the rotor to stick to my fingers in the second to last pic, that's pure magnetic strength!

I was a bit disappointed with the lack of 30mm spacing and 4mm thread mounting holes, so I made an adapter plate to do this. If the endbell on the motor weren't so retarded I would have put the bolt pattern on that instead.

my biggest concern about that motor is the smaller screws and narrower spacing (compared to KB motors) and that might lead to broken screws and stripped threads.

Nice man hands there!! :great:


The motor is standard with 3mm mounting screws and you wanted 4mm? or vice versa?

It has std m3 thread 25mm spacing, MM used a kb45 motor which had the m4 thread 30mm spacing.

dude, intimate and hands are in the thread title, and you left it alone Linc? WTF?

i believe it was being intimate with your hands that caused the stickiness, but you can call it magnetism if you want:lol:

*sigh*

I like how BOTH endbells are screw-captured.

I am also shocked linc left this thread w/out adding his normal " humor "

So far I have gotten this motor past 200 deg. F... in my XLB on 10s 3700mah. Not sure if it was undergeared or overgeared at 12/65 (center diff) and standard buggy diffs, with MT (6") tires. It seemed more like 45mph than the calculated 38mph. Will have to throw the EagleTree on there next time, and play around with the ESC (HV-110) parameters.

hmm, 1051 kv? I really need a 1050. I think that extra 1 rev might draw too many amps for my setup. Are they "dyno-ing" each one to get that number or is that how they all the 12L's are rated? Just seemed funny to me.

All the 12Ls are rated at 1051, this is just the general number they came up with.

Humor needed?, My god Metalman, those r sexy hands, have u thought about being a hand model or getting into hand porn?

I prefer my hands clean shaven tho.....

I guess you are used to shaving your hands... You know why your palms get so hairy, right?

By the looks they definitely made improvements over the 540 series. Where did you purchase this one?

dunno about metalman, but kershaw design has them.

all joking aside, nice write up MetalMan!

This one came from Offshore Electrics.

Who can spot the imperfection on my left thumb? This ought to be far more interesting than discussing a Feigao motor.

:lol: How did that happen????!!!??!!11/1/1/1 :whistle:

How 'bout y'all speculate on this?

Yayy! 20 questions!

1) Were you working on your 1:1 car?

No .

2) Were you using tools of any kind?

Yes.

cool, looks like i nice motor for $110

how does the power compaire to the kb45?

3) Did it happen while you were working on R/C stuff?

The scar on your left thumb was caused by:

While you were using either a Drill press or a mill machine, the part you were drilling/machining came loose from it's vice or your grip. While rotating out of control, it contacted your flesh, ripping and tearing like a big dog.

Note to self: always use a vice to secure work.


Anywhere close?

How's the performance of this new motor?

Honestly, I can't say. The KB-45 was on 6s 7400mah and had a kv of 1200, through a MMM. Now this Feigao is on 10s 3700mah with a HV-110. No real comparison there, unfortunately. Not to mention the buggy is set up differently than before. So the best I can say is "comparable".

No, it happened about 2 1/2 years before I got my first RC car.

Nah, that's where the scar on my left middle finger came from :whistle:

Performance was great! Just gotta work on dialing in the ESC settings and pinion size.

Few years before RC's huh, so a young teen or preteen.

It was a wild masturbation accident!

And i thought I was the only one with those problems.... (sigh) What a relief. :lol:

Oh boy...

You title the thread getting intimate with a motor :rules:, then talked about your injured hand :yes:, what else were you expecting......:lol:

I am just surprised linc didn't jump on it first, he must be turning over a new leaf :angel:, or just hiding his true feelings at the moment :diablo:

Linc has a hand fettish and didn't want to be taken advantage of in this situation... :lol:

Better to have a hand fetish than a paw fetish, nitrosquirter!

Sounds like linc and nitro have been getting a little intimate with each other here lately.

Looks like someone has been playing with the thread title again, I know Arct1k wouldn't do a thing like that.....:angel:

I love how Linc distorts my name in every post.... Makes me wonder his abilities. No wonder he can't finish project, he can't read the instructions...

Update!
 

First off - can't say I would recommend this motor, unfortunately.

Mine essentially died during the first set of batteries. It temp'd over 200 deg. F, closer to 210. I went to run it today, and it did, but 1/3 speed, until smoke poured out of the motor. It had been demagged from the first run.

So, $120 + shipping down the drain in the first 15 minutes. That damn $50 KB-45 lasted longer... I think I will just go for another KB-45, the 11XL (1000 kv) and see how that fares.

Another option would be the Medusa 36-80-1100, but honestly I don't think that will have the balls to push around the ~14lb XLB to 40-45mph.

gotta love KB motors. i just opened up my used 1600kv 8xl and found a couple cpieces of magnet on the end of the rotor. i hooked it up to my vxl esc (lol) and ran it unloaded on a 9.6v battery. in the 30 seconds i ran it, it heated up to 90F. i'm most likey going to order a 1400kv 12L when i order my esc. i'm stuck with KB motors for now as my motor mount only fits them.

metalman, how did you make that adaptor? i want to be able to run 25mm bolt pattern motors.

That heat you experienced from running it unloaded is pretty normal... they are probably 90% ineffecient at no-load.

Made the adapter out of 1/4" aluminum, drilled/tapped 4 holes to 4mm thread/30mm bolt spacing, and drilled 4 holes to 3mm/25mm spacing. Then I cut it with a scroll saw and filed it to shape.

C'mon guys, we need a 4th question!

4) was it caused by a rotary tool?

I would definately say try an 80mm medusa- it can push my ~13lb truck to 40mph or so, and thats with 4lb+ of rotating mass, so if you has sensible shoes on the XLB, I reckon it would do suprizingly well :yes:
