using quark 125 monstor, which motor?
 

i'm using quark 125 monster, i have e-maxx single speed convsersion and will run strobe slipper. i want to run at the track only with this setup. what motor would ya;ll suggest to race with this setup? what voltage ? thanks for any advice

Pretty much depends on the setup and what kind of speed you want.

I'd say a 1940 or 1950 on 4S.

And since you're running the Quark, you could also go with a Neu motor. They're just as good as the 19xx LMTs, but are 4 pole, which runs great with the Quark.

Yeah, the Neus are nice and I'm considering getting one. For an emaxx, you could go with either a 1512 or 1515. I'd go with the 1515 and assuming that you are going with 4S, either a 1Y (2200kv) or 2.5D (1700kv) depending on how much speed you want. I belive that the 2.5D should be all you'll need for the track and will do well for you if you do ever go to 5S lipo. I think that the 1Y is a bit too hot for 5S, although others may disagree.

If you are on a budget 8XL on 4s lipo is good but Neu 1515 1 Y on 4s would be better for it runs cooler and plenty of power on the track.

How does a 1515/1Y compare on 4s lipo (temp-wise) to a 9XL on 5s lipo? Curious is all...

Also, how does a 1y on 4s compare to a 2.5d on 5s lipo? power, and temp?

i think i'll get one of each
neu 1515 1y
8xl (is the feigao/wanderer/nemisis good or get purple feigao/)
any ideas of exactly which of each i should get
this will be in a g2r not sure which pinion yet.
this track is a pro truggy style track, big jumps , not many long straights

oh yeah THANKS for responses i'm still learning and very appreciative of all you knowledge sharers.






i would just love to spank those nitro guys or at least have a drivers chance.

I, too, am still learning. So far, I probably have half a dozen or so Feigaos. I have three 7XLs, two 8XLs, and an 8L. I thought that I had settled on what I wanted, which was a Neu 1515/1y running on 4S. I got all caught up with getting expensive batteries that could keep up with the current demands of a fairly hot setup. Then I ran across a post by jhautz. He was running a pretty big setup on 5S lipo using the fairly inexpensive truerc 8Ah packs. So...I thought, hey, more voltage, less current draw and maybe not need the expensive battery packs. I ventured into running a 5S system. It turned out that the truerc 5S pack is only marginally taller than a 4S 8Ah pack from maxamps. Also, when I went to truggies, I discovered all of that room under the body.

Now...I'm not so sure about the 1515/1y. I think I'm going to grab me a 9XL, to run on the 5S and see how that does. My point is that it's tough to take advise on what will be right for you. It's also tough to give advise on what will be the best for someone else. What you want/need can change with a thought. The Feigaos are also nice, in that they let you try things out before putting down a bunch of money on something really nice. I know that I've spent more on all of the Feigaos that I've bought than I would have on a single Neu, but I do now have a bunch of different motors and have gained some experience.

The best advise that I can give you is this. I know that you will be tempted with speed and power coming from a faster motor, which the 1Y is. I've found that a more conservative approach usually gets you more comfortable running with a minimal sacrifice in speed.

If you are planning to run your truck on a track, I'd go for either the 8XL or the 1515/2.5d. Most of what they lack in speed by virtue of rpms, can be made up for with gearing. It's usually easier to gear up with a milder motor, than it is to gear down with a hotter motor. Geez, I'm getting long winded.

I ran my 1515 1/y on 5s...it ran a tad warmer and my bats actually got real warm. But over all, I would say it's safe. I wouldn't race it in 90* weather though. On my 4s, it runs WAY cool. The controller barely got warm in 70*F the other day.

The only shame about the Neu motors (other than the price) is that there are such gaps in the line up. If they had something in between the 1y and 2.5d, I'd jump on that. Something like a 1900 or 2000kv for 5S for a fast setup.

Neu.

+2 :027:

i run a plettenberg maximum with fan on my quark with 4s in a g2r... i run it on 1/8 scale tracks and its just right... i have the strobe slipper with 16t pinion... i can hold the motor in my hand as right after a run... pretty great setup

where can i find a plettenberg?

I think the Neu would be a better option IMO. :032:

what would be a convincing arguement in favour of a neu instead of a plettenberg?

thx

Cheaper and probably a higher efficiency.. a neu 1512 on 4S on a revo geared for about 40-42 mph doesn't need a fan and stays cool.

are there any data sheets for the neu available?
i doubt that the pletties "need" the fans. so far i havn't seen a "hot" plettenberg.

rhylsadar

What do you need for data? Neu Motors.com has about all the data you are going to find.

They are 4 pole motors with the coils wrapped around seperate "cores". I believe they use segmented magnets, but not sure...

thx. just found the site.

Well, i don't think the bigmaxx has got the fan for nothing.. Mine got pretty hot on my savage.

i've actually seen two types of bigmaxxes. the black ones seem to have a 2 times larger fan.

well i personally never had temp issues with the maxximum in different applications and cell numbers.
anyway the maxximum w/fan and the quark 125 is a very nice combo. a rc colleague of mine has it in his sav with 14 cells and it works excellent.
i have also a bigmaxx (blue) here. maybe i will get some "troubles" with that one. i ll see.

Good thing about the Neu motors is that they are way cheaper.

plettenberg is rather hard to get in the US. since Neu is produced in the US. it's an easy choice.

I don't think the bigmaxx runs too efficient though. perhaps it was the schulze controller that was putting it in an inefficient level.

I thought about the maxximum without fan on the mambamaxx controller. On 4S it should be a blast.

are the prices so high in the us. i thought i saw the maxximum with fan for about 249$. i guess that would be quite similar to a 1515/1.5D which is in the same price range isn't it? they both are around 2700 rpm/v.

but of course i see it is more practical to get a neu in the us instead of a pletty. but that may be the the other way round here in europe.

Nope, the 1515 is more like a big-bigmaxximum.. i would say they 1509 is more like the maxximum.

ok so the bigmaxx is 299$ and the neu 280$. not that big difference.
anyway those neu look quite interesting. but i guess they are more similar than different from the pletties. but i see that advantage of buying a product that is better available in the us.

it's plain stupid of plettenberg it only comes in 1 taste.. 2200kv.. Take it or leave it.. Come on.. That's not serving the brushless market......

+1 For the NEU 1515/1Y!~

yes it would be nice to have more options than maxximum or bigmaxximum for 8th scale conversions from plettenberg. thats for sure.
seems that the market is still too small in their view.

rhyls

Yep, but not to worry.. Neu serves us a good job.. :p

btw, i would say a 1515 has got more torque/power than a bigmaxx.

if you see a 1515 in person; it's a tad bigger. (not to mention longer, since the bigmaxx uses a fan)

yeah more power is always nice. however what i do not like that much about those neu's is the open can.
i know there is this rear cap. but i guess the can was manufactured the way it was in the first place for a reason.

Like you said, there is a rear cap. And the holes in the front of the motor are covered by the motor mount. So, it's good.

Does anyone know/or guesstimate the running temp of a 1515/2.5d on 5s LiPo would be? I'm guessing less than 110F?

Also, what kind of power/torque are we talking here?

Next year I would like to get a Neu.

quick question for you guys about the neu 1512 2d. is it safe to run this motor on 4s in a emaxx should heating issues occure and how about tourque. also why are these motors (1512) cheaper than the 1515 and other 280 dollar neus.

The 1512 is a shorter motor. 1509 is like an "s", 1512 is like an "L", and a 1515 is like an "XL"

The rotor and can length are shorter and the torque output is lower than a 1515. That is why the price is less.

is there a noticeable difference in smoothness and torque and will this push my maxx on 4s efficiently

I forget who it is but someone on these forums is running a 1512 and said they like it alot. The 1512 is perfect on a mid-weight truggy but if your maxx is 10lbs plus I'd recommend buying the 1515.

I have a 1515/1Y for my Super E-Maxx and I run it on 12 - 16 cells.

do you think that it would work good even though it is probably best for a 10lb truggy do you think it would push my ride with enough tourque and effecentcy. i want to use this motor for its higher rpms so i can get the speed i want.

The higher rpms won't necessarily get you more practical speed. I think it's pretty much agreed upon (here anyway) and I have found in my own experimentation that around 30,000 rpm is where you want to be with a truck; or even a buggy for that matter. If you try to attain speed through sheer rpms, it usually means more heat. A better way to attain speed is perhaps running a higher voltage with a lower turn motor and gearing up.

On the other hand, if speed is your primary concern and you aren't worried about extended running, then a high kv motor may just be for you.

What kind of speed are you looking for anyway.

As for which Neu motor, 1512 or 1515, I discussed this at length with Mike (RC Monster). I was asking about a motor for my 11-13lb (depending upon battery configuration) Muggy. His opinion was that a 1512 would probably do the job. Something in the 1700-1900kv range. His recommendation, however, was to go with the 1700kv 1515 and use voltage and gearing to get the speed that you want. The 1515/2.5d running on 5S would turn right at 30k rpm and have monster gobs of torque for turning a big gear.
