Neu 1515/2.5D or 1512/1.5Y, 2.5D... which motor?

[bdebde]

AAngel needs a few more motors to go with all them speed controls he's got. lol

Yeah, to bad they're not compatible! :005:

Bruce, right now, I have seven speed controllers and a motor for every one of them. Believe me, it's a disease. LOL.

zpb, I was running all of my equipment in my 8ight T which goes between 10 and 10.5lbs depending on what battery I'm running. The best comparison that I can make that might relay to you my impression of the 2Y's performance is this....

When running my 9XL on 4S geared 14/46, it was faster and more powerful than the 2Y on 5S geared 16/46. I suspect that the performance would have been closer if I had an 18T pinion to run with the 2Y.

When running the 9XL on 4S geared 16/46, the 2Y on 5S geared 16/46 didn't even come close. When I made this comparison, all thoughts of keeping the Neu as it was left my mind and I immediately packed it up and sent it in to Neu.

Well, I am used to (and addicted to) the 7XL on 4s, so after a few calcs, teh 3D appears like it has much promise for power.

the 2Y on 5s lipo is only roughly 24,000rpm vehicle load, no wonder you didn't see any miracles from it.

Can I get some more ppl with experience with Neu's here! please, I beg you! :002:

[bdebde]

Yeah, I would try a Neu if they could play nice with the MM. The Quark isn't an option for me at this point, the price is too high to not have it work right from the get go (without mods). Doing the mods is not a problem, as I have no problem with smt repair and even etching circuit boards for one off projects, I just shouldn't HAVE to mod it at that price. I may just have to try a new MGM Compro so I can do a Neu (maybe, AAngel gonna be the guinea pig on that one?) for my next project. For now I will have to enjoy my little Lehner that my MM fell in love with. Lol, not trying to rub it in AAngel.

[bdebde]

Yeah Tony, it is a disease, my wife is ready to put me in quarantine!

[bdebde]

ZPB, sorry for the no Neu experiences. I do like the 7XL on 4s as well, except the heat!

Me too, but the temps I got are relatively mild (65- 70) but that was almost 2 months ago now when it was ~15c outside, so the temp will only go up. I just want a better motor.

For a Neu, the 1515/1y would be the approximate equivalent to the 7xl on 4s I would assume. although I haven't run one myself, I did see mikes emaxx running the 1515/1y on 4s and it was every bit as fast as my revo on 5s with the 1515/2.5d I was running at the time. Although I think the acceleration he had on 4s was as good as mine on 5s was because he was running a slipperential and I was running an emaxx tranny and couldn't really put the hammer down and not flip it. He was able to get the power to the ground better.

He threw my 5s packs into his emaxx with the 1515/1y and gave it a run and man... It was seriously wicked! I mean retarded fast.

Here is a little chart that i put together for you on some of the motor and battery configurations I have run in some of my trucks. Just to give you an idea of how they felt to me and the estimated speeds that I was able to achieve comfortably without over stressing the esc.

(Power Rating on a scale from 1-10 of how it feels to me. 1 being a stock emaxx, 5 being highest I would want for a track/racing, and 10 being... well I haven't seen a 10 yet. :) )

Vehicle / Battery / Motor / Power Rating(IMO) / Speed (Est)(MPH)
Revo / 5s Lipo / 9xl / 6 / 40 (hot motor)
Revo / 6s lipo / 9xl / 7 / 45 (very hot motor)
Revo / 4s Lipo / 1515/2.5d / 5 / 35
Revo / 5s Lipo / 1515/2.5d / 7 / 40
Revo / 6s Lipo / 1515/2.5d / 9 / 45+

Revo / 5sLipo / 1512/2.5d 7 / 45
Revo / 6s Lipo / 1512/2.5d Not tested.... Yet :)

Matrix (Buggy) / 5s Lipo / 1515/2.5d / 7 / 45
Matrix / 5s lipo / 1512/2.5d / 8 / 50+
Matrix / 5s Lipo / 1930/10 / 8 / 50
Matrix / 5s A123 / 1930/10 / 7 / 45

As you can probably read into the chart, I think that the Lehner motors are the brutes of the bunch. The 1940/7 on 5s is far and away the most powerfull and responsive feeling motor I own in my opinion. I havent yet enjoyed a 1950 but when mike get them back in stock im planning to get one right away. The neus are good motors too cool running and powerfull, but I personally think that the Lehners are still the absolute top of the heap.

Now don't everyone start beating me up here. This is only my opinion of how they felt to me. I have run other motors and other vehicles, but this should give ZPB a good idea of how I see the feel of the motors on the different voltages. All of these obviously ran on different gearing and and had slightly different setups as all of this has been over a couple year span so this is to my best memory.

I cant stress this enough... This is only my opinion!

EDIT: Damn... thats kinda hard to read.:019:

EDIT #2: Holy cow... lots of posts since i started typing this.:005:

Bruce, you have your setup. I wouldn't even be looking to something else. The Neu that I bought was a real impulse buy. I found it on sale and before I knew it, I had spent the money.

If I was smart, I would have just sold the Compro and Quark and taken the money and put it down on a Lehner 1940/9 hi amp. I would have had to run my Feigaos for a while longer, but then again, guess what I'm running now after having bought all of the high priced stuff.

zpb, I wish I could run that 7XL. I just can't do it. It has to be the weather down here. No matter what gearing I run, the motor gets to 200*F.

After taking some advise, I went and regeared my 9XL to a point where my Quark started cogging (18/46) and the motor temps are still up there. BTW, it was over 100*F down here today. It's funny because it rained a bit. You'd think that the rain would cool things off, but it doesn't. It just makes steam.

[zeropointbug]

Yeah, 70c is almost 160F, it was smoking hot to the hand though, I can't even imagine what 200F would be like...hot. :eek:

That is strange how you are having trouble with the Quark being 'abrupt', that is just excuse my language, @$$ backwards as far as my experience and many others here. weird, you are, hmmm, yes (my friend Yoda says)

It just occurred to me, I have to take into account the gearing range I will want to use, with the fins sticking there and everything....

[bdebde]

The difference with a more efficient motor is just amazing.

Oh, I also pulled the Quark out of my truggy today. Since I have to run the Feigao anyway, I decided to stick with the MM. It runs cooler and I'm not as worried about blowing it up. Besides that, I went out to the track again and I'll be darned if the MM wasn't better for me on the track. It was just less abrupt coming out of the turns. I suppose that I'll just have to play around with the Quark settings a bit more.

[bdebde]

Yeah Tony, I am quite happy with the buggy now, just thinking ahead to the next project. I am getting the itch for a big truck. Not sure if I wanna go truggy or monster truck yet. Probably a winter project though. Got a little fine tuning to do on the buggy yet and get some racing in. Have to just about start from scratch on the suspension after losing so much weight.

[bdebde]

Yeah, it would be a shame to have to grind down those fins to get your gears to mesh, though I think others have.
