Which Neu motor with 5S and Quark 125
 

Hi all,

I am looking for recommendations on which Neu motor I should consider for purchase. I'll be running 5S and the Quark 125.

What's it going in? Is that 5S lipo or 5S A123?

Personally, for a 5S setup, I think the 1515 2.5D is hard to beat. That will give you about the performance you'd get with the 2200kv motor on 4S, but will stress the system less because the current draw will be lower.

I try to stay away from high kv motors in trucks. I like the 30K rpm neighborhood. Again, assuming that this is going into a truck, you're only other options would be the 1Y (2200kv) or the 1.5Y (1500kv).

I don't own a Neu, yet; but I have been running lots of Feigao motors. I'm running an 8XL, which is pretty close to the Neu in terms of kv rating, and my Muggy is downright nuts on 5S. I was going to jump on the 2.5D, but after having seen the 8XL run on 5S, I'm thinking that I might go for the 1500kv motor to keep things sane. I might just order up a 9XL and see how I like that, before I drop the bucks on the Neu.

I'd vote the 1515 2.5d as well.

I'll be running 5S 5000mah MaxAmps Lipo in a FLM Emaxx with 1/8 scale diffs. I was really eyeballing that Neu 1515 1y/F motor, but it runs at 2200kv. Is that too much?

Why are the Neu motors priced so much higher than other brushless motors? What makes them stand out from the rest? I can't find anything on the Internet about them.

I dont believe so this is what i will be running in my heavy metal maxx. serum even knows a guy who runs the 2600kv neu on 4s and he said it ran cool. If i am not mistaken this is the motor that mike used (2200) in his maxx.

I am not a pro on these motors but the reason why i think these motors are more is becasuse they are more efficent, run cooler(with built in heatsink), have little to no cooging, and most importantly they are a 4 pole motor.

Thanks, this is what I'll be installing it in:

The big deal about the Neu motors is that they are four pole motors and they are much more efficient than the lesser expensive motors. As an FYI, I was on the phone today with the guys at Quark, and they told me that their esc runs the best with the Neu motors (actually, four polers, but he used Neu as an example). Something about the Neus liking the timing that the Quarks run.

Four poles mean more torque. Efficiency means cooler running. A Feigao, for example, (not looking for an argument) runs at about 80% efficiency. A Neu runs at about 90% efficiency. You might think that 10% doesn't mean much, but if you think about it, the Neu is only half as inefficient as the Feigao, so it will only generate about half the heat of a Feigao.

I think that 2200kv in a truck is way too much. Especially on 5S. I'm running an 8XL on 5S and I need to slow it down. The 2.5D is just where you need to be. You'll get really good speed, lower heat, and better runtime.

Personally, I'm debating on whether to get the 2.5D (1700kv) or the 1.5Y (1500kv). Just think. If you get the 1500kv, you'll have good running now and then when someone release a kick but controller, you'll be ready for 6S. LOL.

OK, really. I don't own a maxx anymore, but if you want a kick butt setup, I'd go for the 1Y on 4S or the 2.5D on 5S. You won't be disappointed.

Oh, you really have to take what I say with a grain of salt. I like to stay on the sane side of insanity. There are some that run the 2200 on 5S. It being too much is a matter of opinion.

funny that is the exact same setup i am using in my maxx except i will be switching to gmaxx arms. I had made a thread a while back trying to determine what Neu would be best for me on that same truck and i found out to be that the 2200kv was the right one for me and my needs. i was running it on 4s but my needs where around 40mph, reliable, fast but has enough torque and runs cool, and that seemed to be the motor for me.

Thanks,

I appreciate the advice....I'd also like to hear what Mike and Serum think. I am sure Mike will agree 1500-1800kv is the way to go.

Mike does run a 2200kv, but he runs on 4S. The 1700kv on 5S will give similar performance, but run even cooler and stress the batteries less. That what I think anyway. It's in the math.

Also...what runs cool for one person may not run cool for another. It also depends a lot on the temp of the environment. During winter, I can run a hotter setup witout thermal issues. When the summer hits, I really have to tame it down a bit.

I think the 2.5d on 5S would be a safe bet.

Good point. We are moving back to Dallas, TX in July. It gets hot as hell there in the summer.

I'm in Louisiana. I feel for ya.

Throughout all of this discussion, I don't think that you stated what it is that you are expecting from all of this. Are you looking for something stupid fast, or are you looking for something reasonably fast. It's all a trade off. Runtime, heat, and performance are always considerations.

You also have to remember that the batteries can heat up too. The more you strain them, the hotter they get.

I'm really having a hard time choosing between the 1700kv motor and the 1500kv motor. Really, going fast is fun for a while and it's nice to make your nitro friends eat dust, but it really doesn't matter most of the time. What matters most when I'm running is that everything is comfortable.

FYI, there's a interesting discussion in the brushless forum in a thread entitled "Quark fried, blown capacitor." I think that you may find it interesting. I know I did, as my first Quark is coming in on Wednesday. I'm supposed to have a 2.5d coming too, but I'm still undecided.
