I hate sony.

Me 2.



Now back to your regularly scheduled thread.....

AAngel, you have every right to be upset, or frustrated about what kind of 'luck' :005: sorry... you have had this past couple months or so. We are paying top dollar for this stuff, and we expect it to work... and work how it's marketed for! It seems like every manufacturer has their issues these days, each being their own.

AAngel, where is your guardian angel? :005:

I thought 30,000rpm was more for the Feigao motors? Do you think the 1512/2Y would be the better choice then? That's 27,000rpm under vehicle load...

zpb, please understand, I too have limited experince with the Neu motors. I can say that when I evaluate performance, I don't consider the heat factor. With the Feigao motors, the heat was troublesome, but not my main reason for going to the higher turn motors. The 7XL was just plain too much for the our track. The 8XL was better, but still too much. When I hit on the 9XL, everything came together for me. I was able to really work with the radio, without having to take too much care with the throttle and I was able to actually get to full throttle on our track. I posted a video in the brushless forum of my 8ight T with the 9XL running on 4S. If you haven't seen it, you should take a look. A Neu motor, of the same or similar kv rating, should surpass the performance of the 9XL by at least a bit.

I just don't want to give you advise that will leave you wanting more. For me, the 9XL was perfect at around 1800kv, so I'm figuring that the 1.5Y should be a bit better than the 9XL. That's why I went with what I did. Plus, the 1.5Y leaves a bit of room for going to 5S for better performance. All I have to do is swap battery packs.

I'm sure that you are aware of what happened with my Neu. It was just my suspicion, although I think that I am right, that I got a 2Y instead of a 1.5Y.

I will say that the motor ran very well. I liked it. I like the relatively mild setups, but the 2Y (I think) left even me wanting a bit more. If I had to make the decision in the 1512 line, I wouldn't go less than the 1.5Y, unless I was planning on going to 6S. In your situation, with the A123s and such, there are four motors that I'd be looking at. The 1512 1.5Y or 2.5d or the 1515 2.5d or 1Y.

In the 1512 line, there really isn't much difference in the kv ratings of the two motors, so I'd just get what was available. In the 1515 line, I'd go with the 2.5d for voltages similar to 4S or 5S lipo. If you are staying around 4S lipo voltage, I'd consider the either the 1Y or 2.5d. If I was buying this motor for myself, I'd so with the 2.5d for more voltage flexibility. On the other hand, I don't remember who it was, either BrianG or GlassDoctor, but one of them said that Mike gets better temps in his truck with the 1Y on 4S.

Decisions, decisions. I hate making the ones that cost lots of money.

hmm, so do I! ;)

If you didn't see my post up a bit, I just bought two 36v dewalt packs and I am going to make a 7s2p A123, so roughly 6s Lipo performance.

So now with the FET heatspreader clamp coming, and Quark coming tomorrow hopefully, and a nice cap bank, the plan is for it to handle the voltage I throw at it. I suspecting it should, as lipo has quite high initial voltage when fully charged, M1 cells don't, as soon as you take a little bit of current from them they will instantly come down to the nominal working voltage.

So it is a choice between the 1512 '3D' and the '2Y', 1700kv and 1400kv, respectively.

At least you have narrowed your choices down to two. My knee jerk reaction is to go with the 1400kv motor, but I like to stay on the conservative side. I'd also go with the 1400kv motor to be able to gear up rather than having to gear down on the 7S setup. On the other hand, if you go with the 1700 kv motor, you will get GREAT performance on the 7S pack and still be able to run packs with less voltage and still get good performance. From what I have seen, the 1400 kv motor doesn't even really wake up until you get to 5S voltage range. With the 1700kv motor, you'll get good performance running anything from 5S A123 on up.

I think that I just talked myself into the 1700kv motor.

What I want from this whole setup is to have a touch more performance than my 7XL on 5s2p, along with great efficiency (of course...)

Can you give more dirty details on how your Neu (if you think it was the 2Y) performed on 5s lipo? How heavy was your truggy? What condition was the batt pack in, etc...

I'm thinking the 1512 3D on this voltage should give roughly the same performance as the 1515/1Y does on 4s lipo, maybe a little more.

"I think that I just talked myself into the 1700kv motor." You crack me up. :005:

Was Jhautz one that got caps from you AAngel?

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.

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.

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

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:

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.

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.

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.

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.

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....

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

Bruce,

I too had to MT or truggy dilemma. I know that there are a bunch of guys that went with a truggy and bash them, but I've found that the truggies that I've seen are geared more toward racing. I have the 8ight, and have friends with Mugens and other makes and they are built for racing. What I mean by this is that they don't have much ground clearance. Even when I put 40 series tires on my 8ight, it still doesn't have much ground clearance. It doesn't do well in taller grass and isn't much good for getting over rocks and logs and stuff.

When I'm just going out to meet friends for a bash session at a gravel pit or the spill way where things get really rough with lots of things to roll over, I find myself leaving the 8ight at home and taking the Monster GT.

So...I'd say that if you are going to do some racing and light bashing, go for the truggy. If you are only going to bash it, go for an MT.

The Monster GT was really EASY to do. The motor mount was just a piece of aluminum angle that bolts into the existing motor mount holes and I just had to lock the tranny into first gear. I did first rather than second for a couple of reasons. First, it was for my son and didn't want it too fast, and second first gear looked stronger. It's been easy to get it going over 35mph which has been plenty fast enough.

I literally did the conversion in a few hours. The MGTs can be had cheap too. $400 for the truck and then dump the radio and engine for $150. $250 for a brand new rolling chassis plus a bit for the forward only conversion.

If only there were a 1500Kv. 1512 motor, that would be ideal for 7s2p. I sure don't want to have to grind down the fins...

I guess that maybe abrupt wasn't the right word to use. It's just that for me, the MM behaves better with the Feigao on the track. The MM allows me to apply a bit more finesse.

From what I've heard, grinding down the fins to some degree is a must. Perhaps you should consider a smooth can motor.

Well, using Brain's speed calc, the 3D should throw the truck to equal top speed as my 7XL on 16/51 gearing, and the 7XL on 18/51. The 2Y having 1400Kv. is ~42mph geared 18/51.

So the question is if the 1512 finned can work with 16t pinion and 51T spur without grinding the fins down.

Actually, BrianG, the Kv. ratings for two of the Neu motors are mixed up, the 3D, and the 1.5Y. Letting you know. :dft009:

Only finned cans for me please. :017:

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. :) )

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:

Interesting info there. Must have taken a while to compile. :)

Hint: to make it easier to read, put the data into Excel and then copy and paste the Excel data into "CODE" tags (the # icon). This does two things; 1) uses a font where all characters are the same size so character alignment is possible and 2) uses tabs to pad the data. You may have to add more tabs depending on the data length.

EDIT:

Great thanks Jhautz, really appreciate that! :027:

Although the server was down until now, I could not access the website...?

I am still torn between the 3D and the 2Y... I just don't want it to be stupid fast on 7s2p EDIT:(3D) , just crazy fast:027: , what do you think?

And you killed an Enerland cell! That's the first I've read of the kind.

3s is pulling A LOT of amps with that motor

I just emailed Mike to order a 1512/3D motor, hopefully it won't be long before it gets in? Unless anyone knows of another place to get these with good CS?

http://www.nesail.com/detail.php?productID=3859

Give 'em a call first.

Tony

Well Mike replied back, he is going to order it right away. What is the lead time for the Neu motors?

Can't wait to get this rig up and humming with that little devil motor.

Jhautz, when are you going to try a 6s setup with your Quark? As for the caps, wire up at least 2 caps to the input leads, and make sure you have good cooling! :eek: :002:

ZPB- I have the Neu 1512 2.5d smooth can, and it runs 180* in my 8 lb 8ight. I have geared up until my quark got up to 150*.(on a hot day)- I am now at 15/44 and will go up a bit more in gearing. I started at 13/46 and the motor temps have been consistant throughout. I think its underloaded.

I run a 5cell lipo, and this motor screams. I can live with an even 180* (hard on the diff) because this buggy finally outperforms the hot nitros I race against. More acceleration, more top speed, 30 min run time. The only downside is the tall gearing, makes even the Quark seam a bit jumpy. But I'm good with the throttle so I like a lot of power. (I hate hearing 'its too much power - it wont hook up' BAH use yer throttle)

1200w might be a bit much for a buggy after all, Probably just right for a truggy - at 5cells anyway. (and no, I wont go back to 4cells, and you cant make me!) too bad the next step down is a 1509 at 1000w. (the lehner 1930 is 1150, if youve read that thread)

oh, and I had very good CS with flydma.com, but they dont have finned cans in stock and ordering is a two (2) week wait. they are the first disributor on the NEU web site list and show good specs on the motors (better then the NEU site if I remember)

It's good that Mike can get you one. I'd rather deal with him anyway.

I'm really hoping that going with these smaller motors is going to be the right thing to do. Just as a test, I put my 8L back into my buggy. I geared it 14/46 and ran it on a 4800mAh 4S Kokam pack with a MM esc. I took it out to the races tonight and spanked every Jato out there. My buggy didn't run that fast with the 7XL in it and the 6XL would have drawn too many amps.

It's a joy, ain't it. ;)

What kind of buggy did you put the 8L into then? The 8L is capable of some serious power on 12cell(4s) indeed, remember the RC Car Action brushless revo?

I think I made the right choice as far as a motor, either the 3D, or it was the 1515/1.5Y (1500Kv)... but I wanted a nice light motor. My truck should weight in at roughly 9.8lbs now, with the added battery weight, as well as the lighter motor.

AAngel, how hot did the L can motor get after racing?

So I got my new Quark yesterday I forgot to mention. I am going to give it a test run today, to see if it can make the truck move forward... :eek:

I dissected one of the caps that were in the last Quark and it looks like there is some sort of serrations, or major imperfections in the plates of the cap. That is maybe what S&T is talking about 'sub pair' caps. This might have been the reason it popped, and the leads were blown off?

I am wondering if I should remove the caps that comes with the Quark and just use my caps?

Oh man, I lost track of this tread.

Bruce, the L can motor gets outrageously hot in either a buggy or truck. I run my 8L in my buggy for parking lot racing only. For the track, I usually switch over to an 8XL.

zpb, have you gotten a Neu yet?
