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

[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.

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.

[zeropointbug]

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:

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:

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.

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.

[bdebde]

3s is pulling A LOT of amps with that motor

[zeropointbug]

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?

Give 'em a call first.

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)
