Leopard Hobby 4-Pole CC/Neu Clones

[questtek]

That's what I came up with but he said "almost 3hp"
so my math is correct with yours

The short video of the Eagle Tree data from the Insane Hydro was only a portion of the run. At the end of the run when the Eagle Tree data is downloaded in the computer it displays MAX values for all the parameters recorded. The attached pic shows this MAX display and you can see the Max WATTS was 2257.

Doing the math with this MAX WATT value yields 2257/746 = 3.025 HP

Hope this clears things up.

3hp, that's awesome!

[Xfactor]

The only tru test is to run these motors and you will likely find that this "chinese" stuff isnt quite the garbage some think it is.Hey focused thats a PHAT CAT.

[Xfactor]

I see a peak of 1782.2 watts, V x A= W
134 amps x 13.3 = 1782.2 divide by 746 = 2.38 HP

lets not forget that would be peak not continuous.I reall question if horsepower is relevant. Isnt torque what we should be looking at. KT X AMPS? 1 divided by kv=kt rite? KT x Amps = torque rite?

[Xfactor]

It seems the voltage and amperage are relevant but not necessarily in the name of horse power .Voltage gives me my rpm and the torque lets me Know the strength i have to turn that prop at that rpm. The more torque the less difference between the loaded and unloaded rpm rite?

.Hey focused thats a PHAT CAT.

thnx , i hope they sell the big leopards soon i have 2 150 amp 8s modellbau esc and in combination with the 5692/1340 on 8s is just fun.
The drambuie is even bigger than a HPR135.

I'm still not buying the data. How can a motor that is a copy produce more power then the original? A Neu only makes 1250 watts continous. 2500 watts surge. The Neu/castle is at rated less. You want us to buy that a motor built with lesser quality components beats an expensive hand made motor? Somethings amiss here. Steve has done a very decent job at NeuMotors to provide empirical data to sell his products. Some of you folks would buy sand if you lived in the desert.

what is listed from NEU is not what we could actually see out in the water or in any RC
that's what they have posted but just as most any brushless motor they can pull much more than what they are rated to
even the UL-1 and SV motors make much more power than their ratings

Have you pulled one apart and inspected the components ?

Do I need to? Lets state the facts right up front. The motor wires are not the same color or gauge or of the same length and do not have the same end connections? The motor face plate has 4 screws and not 3 like the original that its copied from. Do we see a trend here? Now look at the comments from Castle themseves. They saw them at a trade show and they are built with less quality components! Words that that speak volumes if you care to listen.

What do you guys need? A road map? Hoping is not the same as proven. Factual evidence has shown them to be of less quality. Yet you persist? I dont get it. Parts do not interchange! So they are the same? You live in a different world for sure.

[MarkF]

Yes we have. Joe has some pics of one he took apart. I'll let him post them if he wants.
John, the Neus are capaple of double the rated watts for short periods. I ran a 1521 in an
F3D pylon plane once on 12s 3850s pulling 110 amps. This plane would make your ears ring the prop noise was so loud. Your also right about the quality but I try not get involved with trying to convince people.

Here is what I need. I need to have one in a boat and have it perform like sh*$ before I dis it. The problem is that people are calling it a clone. Obviously it looks similar to a Neu/Castle, BUT obviously it looks different in many ways. Clone? not so much. questtek has been running the motors, and successfully with data to prove it. He also runs with a lot of guys who know there sh*$. I'll tale his word, that for the money, it's an excellent motor. Seems you just don't like it because its Chinese. Don't buy it then. Barely more money than a Feigao xl motor, and probably better. What's not to like?

[crabstick]

@ John - So you haven't tested one yourself, don't accept the real world testing data, and have not personally inspected the components you call inferior, but you take the word of a potential rival company, who has a very bad history of their ESC's going up in smoke, in a lot of cases for no apparent reason... interesting.

So the motor wires are different color, gauge and length.
The Screws on the endplate's are different....

As for Castle's comments, Seriously John are they going to come out and say " Wow these leopard hobby motors are not to bad, not quite as good as our castle/neus but not too bad for the money "

I think the core argument here is ARE THEY AN OK MOTOR VALUE FOR MONEY WISE. And are quite possibly based on a castle\neu

If your of that attitude that I cannot argue with you. You are polarized upon cost. And that will win everytime. I know. I have been sitting right in the same position you are in my past. Nothing I can say will sway you and until facts present themselves showing the dollar value over time its a case of usable product for a dollar amount thats going to be spent. I cant win with that view point. I'm not trying to show folks its money ill spent. I just want the uninformed to not make a leap of assumption and not waste their money with certain expectations. This is a sales and product moderation topic with less then accurate description definitions.

The consumer should be informed without assumptions or mis representations. But I digress.
