Feigao 580L in a Mean Machine?

[questtek]

Has anyone had experience with a Feigao 580L in a Mean Machine? A forum search did not turn anything up for me. I am currently running the 540 XL's but am considering adding a bit more power. Recommendations?

i ran the 6l in a 29" Skunkworks cat. The hull was fast stable on smooth water, but once i started racing or a bit of wind came it was always blowing over. I found it hard to get the seesaw balance of the hull right. I now run a Neu 1515 1y in it and it is a much better boat for racing and faster..

Thanks for the input. I have a new Scorpion S-4025-16 outrunner I want to install instead. It has a 6 mm shaft so I will upgrade the flex drive. It runs at 85 amps continuous and puts out 1500 watts max. continuous. Plan to use either 4 or 5 S Lipos. I have a bunch of new 5000 mAhr , 40 C pacs that might work perfectly in it. Even at 5s the Scorpion will only turn 10,800 rpm so I can probably get away with a pretty good size prop. Lots of experimenting to do after the installation.

I had a Feigao 580 10L. Magnet cracked into three pieces after 4 min run. Save your money, and get a NUE motor.

I highly doubt that you can attribute what happened to your motor with the quality of it. Feigao motors have been proven very reliable when used appropriately and within their respective range. I think i read somewhere here in a thread that your magnet cracking was due to a motor mount ripping out. How does that make the Feigao a poor motor?

I never said Feigao motors are bad. Just simply responding to questtek's question reguarding user experience with a 580L motor. The motor did not sound right from the get go. I had 4 min first hand experience with it. So, its JMPO.
Besides, we were all assuming motor mount ripping off caused damage to the 580motor in my other thread. Read it again since you seem to have so much time.

I run a 580L in my 29" phantom Cat.

Its been great, never had a drama at all.
The cat is a lil on the heavy side, pretty thick lay up. But still goes ok id say!
I run 2 x Turnigy 5000 30C 2s in series to lighten it up a little and im really happy with it.

It does 75-80 kph all day everyday. 50mph.

Well, Tony, since we all assumed the motor mount ripping out caused the magnet to crack, then you can't find fault in the motor correct? I appreciate the childish personal attck as well. Maybe you should save some money by correctly installing your drive components.. Back to all my free time now.

Well, Rumdog, like i said. It was JMPO (just my personal opinion) about this 580 motor. As a consumer, I am entitled to my opinion just like you, and everyone else on here about a certain product. As always, thank you for the money saving tip to install the drive components. Back to see what my employees are doing. Enjoy your free time.

I would like to put in my 2 cents. I've sold many, many of these motors. I've had about 4 returns. ALL of them covered by warranty. Even the motors that were abused(to many volts). You can still send the motor back for exchange, but have to contact feigao first. Also I doubt the sound of the motor had anything to do with the magnets cracking. Magnets don't make noise unless they are hitting the windings, in which the motor would most likely burnup first. Most magnet failures are attributed to, too much rpm or a defective magnet.

Is it true that, if upgrade to boca bearings, does that motor can handle higher volts?let say, if the motor can handle only 6s max. with the stock bearings, but with boca it can handle more beyond 6s.

I would agree with Stephen's comment from Offshore electrics. I have several 540 XL's and they never skipped a beat. I just wanted a bit more power/speed which was the reason for the 580 L inquiry.

However, I did mount a Scorpion outrunner S4025-16 in a Mean Machine instead of the 580 L as a test. This Scorpion motor has a 6 mm shaft, runs 75 Amps, 2000 Watts continuous. It has 14 poles and wound in a 16 turn Delta configuration. BUT it's Kv is only 332. I machined a custom all copper motor mount with cooling for the Scorpion and I knew I could keep the temps low. I have a big HV ESC that will handle lots of amps so it was time to do some tesing with a few 2S, 40C, 5000 mA Lipo's.

The first test on 4s with a small prop did not even get the boat on plane. I remember one of the forum recommendations....Start Small and work your way up. I started real TINY and my Eagle Tree data monitor showed I was only drawing about 5 Amps. I put on a 56 diam 3-blade prop and it was just a tad better. I just did not have the RPM,s. I went up to 6 s and things started to improve a bit but the Amps were still really low. I put on a 678 stainless prop (78 mm diameter) and now things started to happen. I did not have the boat dialed in in terms of balance and thus did not open it more than about 1/2 throttle but it did move. (I did not have the GPS hooked up to the Eagle Tree at this time.) I was still drawing about 22 Amps, 408 watts and 3800 RPM. I was at about 20% capacity on the Scorpion (408 vs 2000 watts.)

If you look at the set up in the attached pics you can see I have an 8S set up...the next one to try after I get the balance under control. This could be exciting.

You will also see a unique mount I made on the top cowl. The aerodynamic mount supports a tiny video camera module I developed for another security project. It is in a titanium housing with glass optics and takes a full 640 x 480 pic at 30 fps. Memory is a 4 Gb micro SD card and power is a tiny single LiPo in the housing. Microphone, on/off button and blue status LED are mounted on the back. I hope to post ome onboard taken video if I can get this beast to really move............or maybe explode!

I think you will need a min of 12s with that outrunner..

It really depends on the wind. The lower kv motors can handle more volts. I have customers running the 580 12L on 8s.
