Just remember, the Chinese are great at making things look EXACTLY like another product. It's what's inside that counts. The Leopard motors may be good, maybe not but just because they look like a Castle/Neu means absolutely nothing.

Everyone has their opinion on China products. It is a personal thing based on individual experiences both failures and successes. Some products have been disappointments to me but this motor certainly has not. Again, my opinion only based on only 4 months of evaluating these motors.
One of my latest projects included using two of the 2200KV versions in oil filled configuration to run outside the hull of an Advenger Pro Cat. Pics are included of this experimental set up. I will post more details as this project evolves.
Here are some specs on the motor........
Watts 2,664 continuous? (I continue to evaluate this with full Eagle Tree instrumentation on every run)
Current rating 120 A continuous. (I have measured 160 amps via my Eagle Tree on speed runs)
Max V 22.2 vdc
Resistance 0.0062
Max RPM 50,000 with standard NGK Japanese bearings
Shaft dia 5 mm.
Weight 374 grams
Length 73.8 mm
RPM/volt 2200, 4-pole
I have placed a fairly large order for the Leopard 2200KV version of this motor so if anyone would like additional information they can send me a PM. I am not or have absolutely NO plans to compete with Steve or anyone who has a business based on FE boats. However I would be happy to help out any one on a limited basis if they can contribute to aiding my continued evaluation of what I consider to be a pretty remarkable 4-pole brushless motor.Last edited by questtek; 05-26-2010, 11:23 AM.Comment

Let me say this . The chinese copy yes but thats part of the deal. We want them to manufacture our stuff for next to nothing and all that copying is worked out in the trade agreements so thats on US. Secondly there are usa companies that suck too. Im sitting rite here with a motor with no damn support. They send the motor to folks with no datalogger to test why?????? no logic.The chinese are just as smart as anyone else so if they want to design something nice they could. No one company is god like they all design based on the phiysical properties of the world were all subjected too no matter what the country that should be obvious. If your professor is chinese in a usa school then wat? that kills all that.We need to remember this is a hobby (no one really cares) outside of us. If you find a cheap chinese version that has comparable performance then you buy it for sport and fun or you put that stuff in rtr models to make them cost effective. If you want trophies better go with the european stuff. THE ONE THING THAT IMPRESSES ME ABOUT NEU IS HE BUILDS THEM ONE BY ONE SO YOU KNOW THE FINE DETAILS ARE COVERED AND YOU GET GOOD CUSTOMER SUPPORT AS FAR AS THE OTHER US COMPANIES STUFF THEY SEND IT OVER THERE TO BE MANUFACTURED SO WATS THE DIFFERENCE?I also have to agree with RUM yes I said it I agree that real world data beats numbers on paper anyday.If I put a chineese motor in something and it runs as good as a pletti for example then it does thats that.The only things Id like to see is when members dissagree they can talk numbers and data without getting mad at each other. Its not that serious 4 one it takes away from the fun of it all and lastly who needs a new enemy? I dont.The purpose of a forum is to discuss. I think one could compare whatever motor he wants. If its a bad comparison one thing that wont lie is the water so let people experiment for themselves so when someone with experience tells them it wont work they know for themselves it doesnt.Hard heads make for soft azzes. You guys get along better come on.FYI I dont trust the american companies anymore than anyone else US Americans are greedy and love to cut corners thats why were in the mess were in. Chew on that.Comment

If you can keep those motors dry u might have something there.No drag. Y not make them vector thrusters if thats the case . The one problem I see is when the boats up on step are the pods still gonna be dragging in the water? and how will that affect handling?Comment

We dont need to bash the chinese we need to put pressure on the USA companies to compete pricewise or give us something sooo much better that it makes sense. As for this motor I got this is my new policy "if you dont have any data or paperwork with your product you can have it I dont want it' that way the next time I buy a motor I wont have to hear about the same damn 460 prop over and over and over again. I hope the company im speaking of is listening. Its the rude arrogance of american companies thats got us behind; just cause you stamp USA on it dont make it special. We need to hold people to a standard to wear that stamp.Now back to the subject those motors look good to me. I want to try the 52 red in a 1/8th scale anyone wanna buy a screamer?I mean leopard has some data I like that for starts.Comment

We Americans are such cheap a$$es! We will continue to get what we are now from HobbyKing, etc. I could bring in motors from China that are setting the FE circuit on fire in Europe. They are incredible. BUT they are expensive and I don't believe the majority of US modelers would pay the price for an unknown (in the U.S.) motor at the same price as a NEU motor.Mini Cat Racing USA

those leopards look good to me for something like that. Lets remember this all the motors are designed to do a certain amount of work. If you ask more out of it thats where you see if a design was redundant or not. They all work like they are supposed too. We abuse all this stuff. Water is very hard on things esp electronics.Comment

I feel like the Castle/ Neu motors are just as good as the Neu motors..Proof is below:
32" Woodstuff Tunnel, 1515 2200kv Castle/ Neu, 5s1p, 7lbs rtr- World record SAW 64.65mph, and can heat race the same speeds for 1mile
36" Woodstuff Tunnel, 1518 1800kv Castle/ Neu, 5s2p, 9.5lbs rtr- 68.8mph GPS, and can heat race the same speeds for 1mile
Now, I am not saying a Neu version of the above will not do the same, but damn, how much faster does a hull of this size and style need to go!
If these Leopard motors are built the same as the Castle/ Neu's then its a great alternative, if not, the Castle/ Neus are still pretty cheap for what you get! Not to mention you can actually BUY a Castle/ Neu..what about a Neu???haha
Don't even get me started on the Turnigy/ Seaking 180a. That is the best controller made, PERIOD. I have propped a motor up so high that the output wires on the ESC melted off the board..Got home, soldered it back together, and I still run it today. I have had that ESC for well over a year, and its been threw hell.Laser cut, birch plywood rc race boat kits- WWW.MLBOATWORKSRC.COM WWW.DINOGYLIPOS.COM
