KB 45 XL got a competitor ?
 

I just found this, this guy is already selling some OEM Hobbywing ESC and feigao Motors

Kinda expensive aint it? Reminds me of the velineon because of the hex screws.

It is quite expensive, but would be a nice option. For many it's nice that it has a standard 540 mounting pattern, but I don't like that. I prefer the 30mm spacing and 4mm bolts that the KB-45 uses. The screws holding the endbells on are a nice touch, though.

A legal BL motor for 1/10 scale racing is sold around 100 € these days... so it's no that expensive. Everthing sold in France take 19,6 % of TAX

maybe it will run cooler having so much more torque than just a standard XL, so who is gonna order one and test it out?

it is a hoss of a motor at 45mm diameter smooth can and XL length, and at 550 grams it out weighs all of the other motors we are using.

i bet it would run good, prolly wouldnt get great runtime but you never know.

i wonder who that is? because he also sells RC-monster stuff

I think it said it has a 5mm shaft. At the bottom of the page, the pinion teeth are called dents. Thats different. I think thats close to $160.00:gasp:

6 pole motor too. Hmm.

Interesting find. I wonder if another vendor carries this motor. I'm not sure if this correlation can be applied, but running a mamba 280-sized motor in my mini-inferno was nothing but a heat pump. I switched to a 400-sized can with tons more torque and about half the kv value and got way better performance and reliability.

Hu, it 's a 6 turn motor where did you read 6 pole ?

Excuse my French but,

Caractéristiques :

2150 Kv
Bobinage 6 tours
Max 120A
Plus de 2000 Watts maxi
Voltage max recommandé : 25V
Diamètre : 45 mm
Longueur : 76 mm
Poids : 550 grammes
Entre axe trous de fixation : 25 mm standard 540
Format équivalent à un Speed 700 en taille
Axe moteur 5 mm avec méplat
Rotor néodyme diamètre 24 mm
Cage démontable
Roulements énormes gros diamètre ultra résistants
Câblés d'origine avec des prises PK 6 mm mâles

It's all there in plain French? 6 pole??

Just looked up some comments on Feigao's 580 motor.. Doesn't seem suitable for car use according to some. Check it:

http://forums.radiocontrolzone.com/s...d.php?t=234845

2150 Kv
6 turns winding
Max 120 Amps
Power 2000 watts maximum
adivsed Voltage : 25 volts (it will turn fast with such voltage ...)
Diameter : 45 mm
Lenght : 76 mm
Weight : 550 grammes
Space between mounting holes : 25 mm standard 540 size
Equivalent to Speed 700 i term of size (Speed XXX it a reference to old brushed motor used in RC Aircraft)
5 mm output shaft with plane
Neodymium Rotor with 24 mm diameter
Dismountable housing /casing / stator
Oversized ball bearing for long life
Default wiring with Banana plug (PK) size 6 mm

what does "very free wheeling" mean ? good for a tekno clutch system ?

Where did you read that ? Guys you should stop using those infamous translator :/

My guess it's about ball bearing that might be degreased then oiled for high speed purpose, or maybe that are just high speed BB

I think free wheeling has something to do with the inertia of a big rotor making it hard to stop or change rotation quickly. A Helli's runs one speed one direction with changing loads.

Killajb posted a link to some dudes talking about it.

Ah gotcha, no bueno then

My bad, I didn't saw the post with the link.

Like Bruce said, it's probably related with the high inertia of the motor.

I googled the part number and got this reference:

Granted the guy may be off, I didn't really do any backup research on it, whups. :oops:

by low rpm does that mean 4s max and what the hell is free wheeling? you can adjust that on your controller.

Some low kv motors have significant influence from the magnets and "thump" as you turn them, I assume this one doesn't?

Normally I read opinons and take them with a grain of salt, but in the link I posted earlier, Jamie from StarluckRC made the "free wheeling" comment. StarluckRC carried feigao, plettenberg and I believe lehner motors at one point so I think he has an idea of what he's talking about.

That does appear to be a completely different motor, though. Or am I missing something?

6 pole motors with 6 turn should be a lot slower than 2000 KV, Btw it' a 700 size motor (check kershaw design 700 HO motor to under stand) not a 580 motor.

:neutral: MetalMan, you may be right! I hope it's a case of mistaken identity, however on Feigao's website http://www.feigao.com/sdp/85838/4/pl-102732.html, they don't list the motor pictured at the beginning of this post..

More research to do..

M'kay.. more good reading: http://www.rumrunnerracing.com/fefor...ad.php?t=26262

These guys seem to suggest the same conclusion, but then again it is probably based on the motor I may have mistakenly thought was listed as the topic to begin with. If this is the case, these guys haven't heard of the motor either. Their opinion of Feigao as a whole doesn't seem to be all that good..

This motor (Feigao 580) has definitly nothing to do with the first motor on the picture (CBRracing Feigao 700). I think this motor was made on demand to cbrracing specification that may explain the price and the fact that you can't find it on Feigao website.

It's a little like CC and Tekin motor, they are definitly not common OEM since nobody have been able to really found the source or the name of the manufacturer of there motors

Where did you see 700? The model number (from CBRacing's site) is:

Looks an awful lot like 580 to me?

When I talk about 700, it's in reference to brushed motor size "speed 700"

Hey Sleeb, what chasis is that in your display pic?
