Which Neu Motor

I've been going back and forth on a new ESC/Motor setup and can't quite make up my mind.

I finally decided to go with the MGM Compro 16016 controller. It shipped today. I'm currently running a Mamba Max/Feigao 7XL setup in my truggy, but would like a better motor. I was considering a Lehner 8T, but it seems that the Lehners are bordering on being vaporware these days.

What I think I'll get is a Neu motor. I just don't know which one. From what I understand, the Lehner 1940 is roughly comparable to an XL can motor. What in the Neu line is comparable to the 1940? Is it the 1512 line or 1515 line? I'd love to go with a 1512, simply because of the broader range of kv ratings (I'm considering the 1900kv). This is going to be going into my Muggy, which weighs in at just under 12lbs., with an 8Ah 4S battery pack. Will the 1512 be right for the job, or should I go with the 1515? If I go with the 1515, my choices will be narrowed to either the 1700kv model or the 2200kv model.

Thanks.

I would say the XL falls somehwere inbetween the 1512 and 1515. I say that because imo the 1512 is easily superior to the L size motors but I don't know that it's quite the "equal" of an XL. The 1515 is probably a notch above an XL. I guess the efficiency just lets the Neus do more work for their size....

You know my advice (I think?) is the 1515 1700kv... that's what I have in my truggy. I like the fact that it can be geared tall enough to be fast on 4s but also should be well suited to a 6s lipo setup on a lower gear.

That's not to say the 1512 can't do just as well... but I haven't actually run my 1512 in my truggy so I can't say. My guess is that it would be fine.

Once racing season is here in a few weeks I may try the 1512/truggy just to compare. If it works nearly as well then perhaps there is no real need to go to the bigger motor.

There was a guy here who ran a 1512 in a huge truck... it was a XTM Mammoth I think?? Anyway he was very happy with it.

I would say that the 1512 is easily equal in power to an XL motor. The higher quality wind and the solid core (which is what the coils are wrapped around) of the Neu make it quite the powerhouse. My 1512 2d works very well in my relatively heavy (~12lbs at a guess) buggy and it hardly heats up.

I think it was jhautz who used(uses?) a 1512 in a XTM XLB 1/7 buggy.

Brian, I doubt your buggy is 12lbs.

[BrianG]

Well, it sure feels heavy. And I do have a lot of "material" on there. I would say it's equal or heavier than my loaded Revo and that is 11lbs with batts.

A nitro Hyper 8 might weigh 8-9lbs., and yours probably weighs less than that without batteries. Your batteries weigh at or under two pounds. Weigh it, and we shall see :).

I guess I'm gonna have to lug everything to work to use the shipping scale. If it's under 12 lbs, I'll be surprised.

You guys are really making me lean toward the 1512. I know that Glass likes the low kv motors, but I really don't like using the larger pinions. Those over 14T. It may just be my imagination, but it seems that motors loose some of their zip when running really large pinions, like 16T and over.

I'm really leaning toward the 1512 1900kv motor. That should put me somewhere in between an 8XL and a 7XL. I'm looking for that range because there are times when I feel that the 7XL is just too much, but when I tried the 8XL there were times when I felt that it just wasn't quite enough. Again, maybe it's just my imagination.

Now...I'm looking at the 1900 kv motor because the specs say that it's more efficient than the 2000 kv motor. Am I right? I'm figuring that the 1900 should give me better runtime with less heat at the sacrifice of a negligible amount of power. If I'm not right about this, I'll just think more of the 2000kv motor. Hey, all things being equal, I'll take all that I can get. The 2600 is just too much to even consider.

If I do wind up going with the 1515, it'll have to be the 2200 kv model. I think the 1700 kv motor will leave me wanting more.

I just realized that if the 1512 doesn't get it in my truggy, I could always just put it into my buggy and get the 1515 later.

I hate making decisions like this.

I went and found that thread on the XLB. It turns out that it only weighed around 10lbs. My Muggy goes just under 12 and I'll only be running 4S. How does the Compro 16016 handle 5S?

I'd really like to go with the 1512.

I have the 1512/2.5D and the 1515/2.5D and I actually prefer the 1512. Its snappier and feels more nimble. Plenty of power too. If you ask for my vote betwen those 2 motors its the 2000kv 1512.

Ive run them both in the XLB, my revo and my 1/8 buggy. The 1512 is the better motor in all of them IMO.

I run them on 5s and there are no heat problems with either motor so depending on what you are planning to do I'd say you could easily go for the 2200kv 1515 and have no issue with heat on 4s (probably even 5s for that matter). They are cool running motors.

I think you are right about the 1700kv motor leaving you wanting on 4s. It leaves me wanting somewhat on 5s. EDIT:Of course I think there might be something wrong with me. :p

jhautz, just the man I was looking for. As I said, I'm going to be putting this into my Muggy and it comes in a just under 12 pounds. I'd really like to go with the 1512 2.5D or 1.5Y. The 1000 rpm/v should make that much of a difference.

The 1515 was my knee jerk choice, but I don't want more motor than I need. I'll just wind up with more of a current draw than I have to live with.

So...are you saying that on 4S, I should go with the 1515 2200kv motor? Or do you think that the 1512 2000kv motor will do nicely on 4S. I do like fast, but want a setup that I can race on the track too. Perhaps the 1512 1900 or 2000kv motor with 4S for the track and then I can run it on 5S when I want to go fast.

Thanks for all of the input guys.

More Motor than you need.... Your Funny!:D All of these are more motor than you need. Thats the Point!!!

No heat issues with the TrueRC Lipos. They are pretty solid for the money. Yes you can get better performance from other packs, but great bang for the buck. Just make sure you get a big enough pack so that the 12C is enough current. 8000mah would be the minimum I would go for in TrueRC.

If I was doing the choosing, I would go with the bigger higher KV motor. Run times might be a little lower, but it would really cheese me off of I built a whole truck around the BL system and then was diapointed with the power. If its too much for the occational time you take it to a track. Gear it down. The motor will handle it. Plus it sounds like your truck is on the heavier side.

Oh, by the looks of the video, you (jhautz) like to run your cars hard too. How did that truerc pack hold up under stress? Did it get hot?

OK, so the 1515/1Y it is. That was what I wanted in the first place. As they say, you should always go with your first instinct. LOL

i have 1512/2.5d (2000kv) on 16 cells and my 12lbs maxx is an instant rocket. Just cant imagine having more torque :) but for 4S 1515 2200kv is prolly better for racing. but get good tires :) had to move to big joes as no other could get a good grip with all the power Neu has :)
