Default My Goodness..........Castle's BIG Monster!!

Wow, this thing is a brute[X(].............#1717 - 1580kv and, get this 50mm x 85mm long...............man, on 6s you could pull stumps. For comparison a MMM 2200kv is 40 x 75........

Wonder if you could run 1/5 scale with this?

It'll go in my future e-maxx on 8s, 46,000rpms with ridiculous torque!, you would need titanium gears

It just may work on 8s.................the 2200kv runs about the same rpms on 6s as that would on 8s................Who knows.........

- The meaningful data is missing from that chart.
- This is not a Neu design.
- The motor is made in China.

Why should this motor cost $170 or more? Aren't the Neus US-made?

They could be.............. here's the "blurb" at the top of the page introducing all the motors........

Five motors based on Steve Neu’s awesome 15 series motors, and the brand new Castle 1717 motor are works of mechanical art. They feature high quality oversized bearings, sintered Neodymium magnets, superior electromagnetic design, and rigorous engineering control in our own factory resulting in a Monster motor we can put our name on.

However, it doesnt "say" Neu on the top of the chart by the 1717 motor..........

I doubt it. Looking at the page ( I don't have it up any more) with the Castle brushless Mamba motors, it is the only one that is 'Castle Creations' instead of 'Neu-Castle.'

Not that it is crap if it isn't a Neu design, but I wouldn't think they'd get away with charging the same. (unless they hired Steve Neu or something)

There's no doubt in my mind that the new Castle 1717 motor (whether officially licensed as Neu or not) is just as good of quality as all of CC's hardware. Some people consider CC's stuff expensive, but I consider it a huge value. If the stuff ever breaks due to a defect or worksmanship they'll warranty it. Otherwise, you could throw it off a cliff, run over it with a train, set it on fire with napalm, and they'll still replace it for a fraction of the cost no questions asked. I'm sure I sound like a fanboy or that I'm on the Castle payroll, but that's just how I see things from my personal experience and everyone I've talked to who has needed repairs.

Chances are that the 1717 design differs just enough from Steve Neu's designs that they don't have to pay royalties to him, on all the other CC "official Neu" motors they do. If the 1717 was an official Neu the price would be higher. Also, the prices listed when buying direct from CC are MSRP, once the other dealers start getting their supplies the prices go down. You can find the 2200kv 1515 and 2650kv 1512 for almost half of MSRP now if you shop around.

If castle has a good design team, they've hopefully learned the lessons they could from Steve Neu and can now incorporate that knowledge and/or methods into designing good motors of different sizes. I really wish they'd go back and redesign the 1/10th scale (cm36) motors for instance. Using what they learned by partnering with Steve.

Most genuine Neu motors are built-to-order if I remember. Castle had to get the cost down low enough to survive the ship-and-sell type distribution scheme that predominates the hobby marketplace today.

The main thing you have to look at when comparing motors this big is efficiency. Most of the cheaper big motors aren't too good in that respect, they end up baking themselves when you try to put any kind of real power through them.

Yeah, Castle had no choice but to run mass production, especially when the original MMM combos started coming in the brushless E-Revo and Savage Flux.

I think the efficiency of the Neu-Castle and Neu motors can be close to or upwards of 90% depending on the model. Compared to the efficiency of Feigao, EZ-Run, and other Chinese "XL can" motors this is huge (I think average is around 70-75%). Even when looking at a system that draws only 1000W, 70% efficiency means 300W is being turned into heat, while 90% efficiency means only 100W is wasted as heat. Packing an extra 200W of heat into a relatively small motor can and will mean the difference between a safe setup or burning the motor up.

Yeah, when you start talking about 85% plus efficiencies, even a small 5% or so can make a big difference. 5% can mean a fourth or a fifth less heat (20%-33% less) generated by the motor.

Some guys will put them in their big 1/8th trucks. I've seen one in an LST2 so far, and it makes the gearbox look tiny. Insane amounts of power. Might be overkill, but that's what needs to be done sometimes!

The big 1717 is most likely more efficient the the feigao's and cheap chinese motors.......it just may not be quite up to snuff with the other Castle-Neu's................but, it does have the same oversize bearings as the other Neu's......so rpms probably wont hurt it........8s seems like an option......?? Here is the rundown now on their motors they offer. If i were to buy a big castle now (got a 2200kv) i would opt for the big 88mm if i had a 1/8 Monster..................

It actually is a Neu design, How about you do some research before posting wrong information, They aren't calling it a castle/Neu because is there a Neu 17 series? No there isn't.
Also in case you haven't known that the Neu/Castle motors where also made in china. Whats wrong with that? Real neus are made in US, But if it is the same design what is the difference where it is made?
Edit: If you can even understand the inside of a brushless motor or understand the designs between this one and a Castle/Neu I would love for you to point out any differences.

Speaking of doing one's research, how do you know this?

Also in case you haven't known that the Neu/Castle motors where also made in china. Whats wrong with that? Real neus are made in US, But if it is the same design what is the difference where it is made?
Yes, I did know this. The difference in where it is made is simply a matter of whose citizens we are helping to stay in work by buying a certain product. My point was that for that kind of money, we should be supporting US jobs, and the probably higher US build quality.

Edit: If you can even understand the inside of a brushless motor or understand the designs between this one and a Castle/Neu I would love for you to point out any differences.
http://www.rc-monster.com/forum/show...44&postcount=2
I would be happy to. Send me a sample of each motor, I will take them apart and tell you what the differences are. I sure can't do it from your link.

More importantly, I'd like to see the quality records from Neu's US product vs. the Neu-Castle China production. I'd bet my next paycheck the quality is higher and more consistent from the US.

By the way yfz, I can understand the inside of a brushless motor, and I understand the basic electronic theory of how they work. They are small three phase AC motors. If you're familiar with how industrial 3 phase induction motors work, it is very similar, except that these have stator windings and a magnetic rotor instead of a laminated steel rotor. The AC is provided electronically and manipulated by the speed control instead of being sinusoidal AC from the source.

I'm sure the only difference between the Neu-Castle motors and the equivalent Neu motors are in where they're produced. As we all know, it is much more difficult to maintain quality in China than here.

http://www.neumotors.com/Site/1700_series.html

There is a 1700 series, but they are small, 1704 and 1706, only 4 different models, and looks like they are for planes or helis

While the 1717 is no doubt equal quality to the officially licensed "Neu" design motors, it isn't an official Neu. The only reason I started that thread at RCM was to see if there were any notable design changes, just curious.. I'm waiting to see what Patrick says about it.

Thats not technically a 1700 series measured the same way as the Castle 1717... Its for sure the quality of a Castle/Neu and what you would expect from castle.

I guess i'll ask one more time......Anyone know if you can you run it on 8s? rpms would be in the mid 40's
