Leopard Hobby 4-Pole CC/Neu Clones

[m4a1usr]

There is not a 2000kv Castle/Neu. The 1515 is 2200kv. I own 2 of which in every way perform as well as the 2 Neu 1515 1y's Ive owned. I actually am currentl running them on 5s with x447 props in a twin cat with very little heat. I dont know if we can reall call a motor a copy. I mean, Brushless motors all really have the same design with the obvious variants in windings/poles, etc and quality of the parts. It's like saying that a lipo is a copy of another.

Wow. A typo. What a loss to the RC world. The castle/neu 2200kv is not the same as a 1515/1Y. Doesnt matter what you think. Post some empirical data to show your testing. Even OSE states the motors are not the same. Open end bell design for heat removal. No clear statement of what the castle/neu are made of for comparison? Got a chinese factory you would like to list? Like the iron and the magnets? The Neu's are made in the USA. The quality rivals the Europeans at a lesser cost. You got some nerve.

LOL. Take it easy man. Buy what you want. And yes, I do have some nerve. The data is in the performance. Which I am happy with. They PERFORM in real world testing as well as my Neu's did. Believe it, or don't, I could care less.

[Jeff Wohlt]

Maybe we should not compare the NEU as we know where they are made...right here...we think...but Castle is a different story. It has been well known that they made over there...but with Steve's specs. I doubt they are too close. Steve has his own knowledge of what really is demanded from a motor...sure they could be close.

Guess we will see.

You know,........it took me 5 years pf playing with the cheap chi crap to realize what Jay was saying back then.

The bitterness of poor quality remains long after the sweetness of low price is forgotten.

My hat is off to you Jay. You were right and I was wrong. I'm trying to educate them.

John

[Jeff Wohlt]

Yes...but if they are just shy of the same performance then who is right? $ vs $

We all know there are plenty out there ripping designs...we have are own right here in the USA.

[Rumdog]

My boats are full of that "cheap chi crap." Turnigy lipos, Seaking esc's, Castle/Neu motors, Feigao motors. I choose to run components that I have had good results with. I try less expensive things and if results are good, then I have no need to splurge. How do those quality USA Castle Hydra controllers seem to be doing lately? Do we call them cheap US crap?

I don't mean to offend you, as you seem like you're experienced in the FE world... but there is no appreciable difference in the performance of the Steve Neu Motors to their Castle Neu equivalents. Notice that the Castle's are larger in dimension than the Neu's comparing any Castle equivalent to one (1515 to 1515 etc.). The Neu's are obviously built more efficiently in size to power ratio (probably tighter windings or i could be wrong and the Castles simply made up for lack of cooling holes with a larger cooling surface area).

But comparing motor for motor, they put out just about the same power in my experience. Any difference in performance for the majority of people is neglibible and could only be noticed in a SAWs boat if anything. I have also noted that the Castle motors have a more notchy feel; it is my understanding Mr. Neu did this on purpose on his motors and do not know its effects on the motor's torque. To my knowledge, the only difference between the Castle/Neu rotors is that the Castle's are Kevlar wrapped instead of CF.

Sounds like your minds already made up John, if it comes from china, it must be crap, is what I get from that statement.

5 years ago, I probably would have agreed with you, Now, after racing (and winning) using "cheap chi crap" as you put it, I will quite happily use some of it. While I agree, some is crap, some is not. There good stuff coming out of china now, 5 years ago.... not so much, hating on something because of its manufacturing origin I just don't understand.

as an example I personally would not ever buy a castle ESC, no encourage anyone to buy one, too many of them just burn for no apparent reason.. I have a 120amp Hextronic ( cheap chi crap ) that I just cannot kill, have been abusing it for 4 years now...

[Brushless55]

Funny how some think if they spend 2x or 3x the money they get better products that will outlast and outrun the cheaper priced items
where do the components of the high dollar items come from?
put together in the US, but...

and why are some already ripping these motors apart when not one person on this site has run one?

[Steven Vaccaro]

One thing, I've been in contact with a distributor on this motor.
They are saying its a 2 pole motor.
But, It could be possible that they just don't know what they have.

Thats good news.

Infinity 4 Pole motors

Heres another family of knockoffs (Trinity?) these new 4 poles look interesting.

They come in 39, 43 & 54mm dia cans Nice big hefty motors at a great Great price!

the specs on this one for a 6S setup look incredible!

One a side note, one thing China is known for is taking a bid to make a product for another country and using that knowledge to make a better version they sell themselves as their own design. Then once they get market control of that product, they slowly cheapen it up till it's a decoration.

This is not new, it's been going on for decades or more. It's well known in the aerospace industry, especially when working with DOD or any US Proprietary design data, that even talking with a Chinese national regarding any design is considered and ITAR violation. There were actually special red lines drawn on the floors they they had to stay within 10 feet of at all times.

Any and all sensitive government design knowledge has been historically withheld from the Chinese for just this reason. Which is why there have been some major problems with China trying to build Helicopters and parts for Russia. The US won't give up the design info for any Chinese factory to build.

Basically, if a US Company has a Chinese company build something for them, the Chinese government takes that information and has their own version built. Google found this out first hand. There was a search filter software in WA a couple years back that China completely ripped off, even leaving their name in the code and deployed as their own with all new computers... Dell was having a choice of employing the software or leaving the China market. It's just how they do business. Remember, it's a communist country.

Back to the knock off motors... They may be just as good... might even be better at some point... and will most likely have really bad clones mixed in there somewhere unexpectedly...

.... carry on ....
