Who is running Feigao 580L motors???

[txboatpilot]

I am thinking of ordering a 580L (10L) motor to try in a 36" Rigger on 6s...

Just want some feedback from those already running these motors.. Setup and which wind you are running would be great.. TIA

I had a Feigao 580 10L, ran it on 6s2p in my 37" H&M Maritimo on her maiden run . It was a strong motor. First two minutes, everything was fine. However, the magnet cracked into three pieces within the next 2 mins run. I guess the motor mount broke loose from the hull was the cause...

Anyways, IF you do decide to get the 580 10L. I sugest you should replace the bearings asap. The original bearings sound like frictions...

I have a 9l I am going to run in my 34" sprintcat on 6s

Thanks bro,, just what I am thinking of,,, mabey 9-10L on 6s2p in my Whiplash .40 and .40 FE Rigger...

Please let me know how your 9L works in the SC40....

I wonder what ESC he was running with the 580

I bought a 29"Phantom cat from Ozzie-crawl.

It runs a 580 6l on 4s.. Very happy

any chance of seeing under the hood?........interesting hull ......what kind of performance you getting?

That's got to be a pretty fast set up in a 29" hull. 6L on 4S is what i'm thinking of putting in my 34" TS JollyCat.

What are your run-times like (on what size batts)?

Heres some pics

To be honest, i bought it off ozzie - crawl ", not long ago as we run the boats together on weekends. He started a thread on it called "Project - X "

He gave it to me with some ( i think ) Zippy cells?
3700mah 4s ?C. Which i run in parallel.

Decided to order some Turnigy 5000 30c 2s which ill run in series.
Hopefully this will lighten up the whole setup, as the boat its self is quite heavy and the batterys are killer heavy? + the cells should have more punch

As for now, its doing 70 -75 kph ( 45 mph )
Hopefully when i get the weight out of her she'll start movin!!

Esc is Hi- model 200

Motor timing? No one speaks about motor timing using these big motors. Where should timing be set? I first used the factory default setting of 10 degrees and motor ran very warm (170 degrees) without water cooling. I have since lowered the timing of my MMM controller down to 5 degrees hoping temps will be lower next run.

My current hull and setup: Phil Thomas SS 21 Hydro, Castles Air cooled MMM controller, 6s1p 4200mah lipo, Fiegao 580 9L (1,426kv), Octura m440 prop

Wow 170 isnt that strange when leaving/running it on 10 degrees , its a 2 pole motor so it runs best on 2 degrees anything above 2 degrees will result in less efficiency and more heat.

Thanks for the advice. I will try 2 degrees

...its a 2 pole motor so it runs best on 2 degrees anything above 2 degrees will result in less efficiency and more heat.

Actually this is not an accurate general statement. The optimum timing advance for a 2-pole motors depends on the load applied to the motor. If the load is low, then 2 degrees is probably okay - but we seldom run our FE boats at low amp draws. The higher the amp draw, the more timing advance is required. Too little advance can cause motor overheating too since the timing is not optimized for the load.

The big Lehner 3060 motor (2-pole) in my T cat runs poorly if I run it on the Schulze's lowest timing advance (~5 degrees). It runs best between 15 and 20 degrees because that matches the load on the motor. The Hacker and Feigao XL motors that ran for over a year on Castle controllers with the old faulty version 1.03 firmware ran fine on 15+ degrees of timing because most of them were loaded to an appropriate amp draw.

I suspect that detox's heat problem is due at least in part to his too-small prop. For that large motor an x440 is just too small and is not loading the motor enough, giving excessive rpm. While I have not run his setup, I suspect that he'd be better off running a more appropriate prop for that torquey motor. I'd try an m445 at least.

WOW! Thanks for answering Fluid! The boat is fast using the small m440. It will be a missle using the larger m445. I just hope the air cooled MMM controller holds up to the larger prop.

BTW...what kind of amps do you think my combo would be pulling using the m445 prop (Phil Thomas SS21 hull, 6s1p, Fiegao 9L 1426kv, Castle MMM controller, m445 prop)
