Castle motors Watts?

[DISAR]

Does anybody know the watts for these Castle motors 1515, 1518, 1520, 1717?

I have the 1515 and it is slightly bigger than the Neu 1515, hence it can handle more watts I believe. But what are the limits for these motors?

Not sure, but i have the 1515 and 1518, and they both RIP!! I run the 1518 on 5s2p in a Rico 31 mono with a x548 and It has Tons of power and comes in nice and cool. Gonna swap it out into a DF 33 soon and see what she can do. These are the only specs I know of...http://www.castlecreations.com/produ...le_motors.html

What kind of speeds do you think you are getting with the 1518 on 5s?

[DISAR]

Looking at the dimensions of the 1518 it is almost the same size with Neu 1521. Same watts?

getting 58 mph with crappy 20c cells. Have some new 30c on the way, and gonna run a pitchier prop. I'm guessing watts are close to the 1521.

I personaly dont think thats true. Castle is implying on their home page that their Castle-Neu motors are approx. 85% eff. when compared to cheap chi 2 pole motors. And the Castle-Neu motors are made in China, not the USA. They are advertised with sintered rotor magnets. There is nothing in the advertising stating individual continous wattage ratings. Thats why I have my doubts about putting them on parr with Neu's and I bet I am right that they dont exceed Neu ratings even if the can is larger.

That's why I am asking here to see if someone has any experience with these motors comparing to Neu. The difference in price is about 50-70$ but do they have same power?

58 mph is very good! with a cool motor.

I know alot of guys love the 1515 motor in their ERevos
but I don't think they have the exact same power as the NEU motors

I personally don't see how they'd be different power wise.

I personally don't see how they'd be different power wise.

Differences could be quality of magnets, iron and of course efficiency. All contribute to how much electrical energy is used effectively and not wasted to heat. Its probably not much, but I have not done any emperical testing to know for sure. Might be little, might be none, might be ?

i have a 1717 that i am putting in the df 35 hull...far from completing it though..i will post the results once its done for some more comparison info

I personally don't see how they'd be different power wise.

Okay, let's see.....
- tightness of winds
- quantity of wire on stator
- quality/gauge of wire on stator
- quality of magnets
- length of magnets on stator
- temperature limit of magnets
- quality of bearings
- air gap between armature and stator
- quality of armature laminations
- thickness of armature laminations
- straightness of armature shaft
- quality of assembly/endplay

It's easy not to see the differences if you don't want to look very hard......

Aren't they supposed to be the same motors, but assembled in China? That is what I meant by my comment, Not that I don't understand what makes a motor good or bad. Have YOU seen the differences?

[DISAR]

For sure there will be some manufacturing differences but at the end of the day what matters is performance, speed, temperatures and endurance.

But why Castle don't make public the watts of these motors? Probably some kind of deal between Neu and Castle, who knows.
What I do know is that from my testing a Castle 1515 is better than a Feigao 580. I haven't compared yet with a Neu1515 yet though.

IMO, if you want the edge get the NEU motor
