Recomened setup! Hurry!
 
Im going with a NEU so waht motor and ESC? Im going with 14 cell right now but 4s later. Can a MM handle this motor?

jnev 06.20.2007 10:46 PM

Some people have cogging issues with the Neu and MM, but for others it works fine. Nobody really knows of it will work for them.

zeropointbug 06.20.2007 11:07 PM

Neu and Mamba Max esc is really NOT recommended. When it cogs and too much throttle is applied, you can burn up the controller.

I would either go with a Compro or a Quark esc.

What Neu motor is this?

E-Maxx King 06.20.2007 11:10 PM

A NEU 1515 1.5d/f or a NEU 1515 1y/f. So there only two controllers that work? What about gearing? 66/18?

zeropointbug 06.21.2007 12:14 AM

Go with the 1515/1Y, hands down.

Go to BrianG's speed calc for your top speed.

Yes, there are really only two options right now for esc's and Neu motors, the Quark and Compro. I can't even force myself to recommend either one though... :002:

E-Maxx King 06.21.2007 12:18 AM

Well the 1.5 is fasters tho?

zeropointbug 06.21.2007 12:25 AM

Yeah, so...

Do you want fast, or break your truck into small pieces and burn up your batteries 'FAST?

E-Maxx King 06.21.2007 12:29 AM

Break what? Will upgraded stock diffs handle the power or is 1/8 size a must?

so gearing and runtime? Can the 1y hit 50? Or is an 8xl better?

zeropointbug 06.21.2007 12:52 AM

Is this your first BL setup?

Trust me, and everyone, and anyone with a sane mind, you do not want to go 50mph in a truck.I hope you have nothing in your drivetrain that is stock with ANY BL system, it will chew it up and spit it out.

You will have your hands full with the 1Y, and that is the limit for those batteries anyways.

Just get the 1Y if you want a Neu, and go for the Compro or the Quark with RC-Monster heatsink mount.

E-Maxx King 06.21.2007 12:58 AM

the neu is finned. So how much torque and runtime? Can upgraded stock diff handle the power?

And yes this will be my very first BL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

AAngel 06.21.2007 02:10 AM

King, not to get down on you or anything, but this is the second thread where you've asked for advise and then argued with those giving it.

The general consensus here is that running a motor at no more than 35,000 rpms is the way to go in a truck. The two best motors that you could get are the Lehner and Neu, but you are asking about the Neu motor here. If you are going to run a Neu, you need either a Compro or Quark controller. To stay under 35,000 rpm on a 4S setup, your choices start at the 1515/1Y on down the kv scale.

The 1515/1Y is very popular for truck applications, but some go with the 2.5d for more conservative running on 4S, with the ability to go to 5S for more speed. Of course, you could run the 1Y on 5S for a bit of insanity, but it will run hotter.

You also seem to be stuck on the speed issue. You asked about 50 mph. I really don't think that you realize what you are asking for. 40 mph is fast for a monster truck. At speeds over 40, most MT tires are going to be ballooned to the point of being pencil thin at the point where they meet the concrete and steering will be iffy at best.

If speed is all you are worried about, you might be better served converting an on road car or maybe even a buggy. I know that my buggy does over 50 pretty easily.

As for how much torque, it will be sick. You can't even imagine what the torque will be like. You can watch videos and they still don't convey what it's like to see it in real life. The guy who owns my LHS has been in the business for over 20 years and when I showed him my MGT conversion he said that he'd never seen anything even close to having that much power. When I let him drive it, he had a hard time keeping the truck on all fours.

This was with a Feigao 8XL on 4S in a 13lb truck.

From what I gathered from your posts, you will likely be best served with a 1515/1Y. It may not get you going as fast as you think you want to go, but it'll be the closest that you can get and still have a dependable setup.

The runtime will depend on how you run, but I'll go out on a limb and say that if you go with the 1Y and 4S lipo, you should get about half an hour on an 8Ah pack.

I've gone a completely different route. I've gone light in my truggy for racing purposes. 4S lipo, 1512/2.5d motor, and 5Ah battery pack.

E-Maxx King 06.21.2007 02:39 AM

I know but Im a noob. SRY! I read on the neu 1y. RICEMAN ran that motor on a MM? I just PM him to get to the bottom of this. I think brother will just get me the 8xl if the neu doesnt work on the MM. PLZ Work. So I be wheeling like crazy on the stock chassis!


There was a thread a while back and he used the airplane 125b cause he said it was half the cost. Where can I get this?


Also will the BK Electronics 12020 run it? Where do I get a cheaper ubec?

O and do I have to order male and female 5.5 plugs?

Its going to cost $700!

AAngel 06.21.2007 10:32 AM

King,

A few are running the Neu motors with MM controllers, but the majority of those that do have cogging problems. Running a Neu with a MM is going to stress the esc.

If you go with an airplane controller, you'll have to arrange for mechanical brakes. To me, it seems that the expense and PITA (present and future) of running mechanical brakes outweights any savings that you might realize by going with the plane controller.

I believe that the BK controllers will only handle two pole motors. The 5.5mm connectors aren't absolutely necessary, but they do work well.

If cost is a big factor, you might be well served by a MM/Feigao 8XL setup.

suicideneil 06.21.2007 06:05 PM

Ebay for a 'cheaper' ubec, but cheap often = nasty. I hope you have upgraded to FLM hybrid bulks & HB diffs, 3.3 drive shafts and good quality centres, steel idlers& locked the tranny into second. If you havent done all that ( and more ideally ) you are going to end up with a really nice BL setup in a really weak truck. At the end of the day a stock Emaxx is not designed for any kind of BL power- read around the Emaxx & BL sections and research the upgrades done- then you will have a better idea of what you are dealing with.

Another option is the HV4.5- drop in system that just requires a few minor up grades. Its better for noobs since although it doesnt have anywhere near the same torque, the motor can still get you up to 40 mph quickly and it can run at higher temps/revs (though not a good thing, it can take it better than some setups). Good batteries area must though.

Do you know anyone that has reached 40mph in an HV-maxx? I don't know, I am asking? I thought 35mph was the limit.

suicideneil 06.21.2007 06:21 PM

35-40mph..... I like to be optomistic sometimes. I figure the lighter the truck, and the more cells -14 or maybe even 16 with a few tweaks to the esc-, and it should do 40 without too much trouble.... its just the heat issue. But then Novak must have taken that into account surely given the 70,000rpm+ the motor would be doing on just 12 cells (4.5 motor).

It makes me so sad I didnt have a digital camcorder when I finally made that last run with the TXT-1- insane acceleration/wheel spin, and amazing topspeed for a 12lb truck. I base the speed estimate on my old madbull- it does 20mph stock, and the TXT-1 was easily going nearly double that (the amount of ground covered in the same amount of time). It lacks torque, but speed is impressive....

Well, if it has enough torque at the top rpm range, that is all that matters for speed.

suicideneil 06.21.2007 06:37 PM

True, I guess the torque comes from the gearing:
1. XL can motors have oodles of torque so can gear up loads for more speed.
2. HvMaxx lacks torque but can rev much higher, so gearing down creates the happy medium between speed & torque required to shift the truck.

Something like that I think. All I know is it works when I plug it in & hit the throttle.... I will get a vid sooner or later of my truck working the way it should- its just pouring down with rain like you wouldnt believe at the moment = British summer........

E-Maxx King 06.26.2007 08:35 PM

So with FLM Hybrids, HB diffs, RCM centers, rcm idlers, and 3.3 mip cvds. So Its down the the 8xl and mm or a neu 1y and monster pro. 1y plz1 LOL! Sorry I havent been replying because my computer has been down. Am I able to put 16 cells on the 1y for fun?

E-Maxx King 06.26.2007 11:52 PM

Anyone?

jhautz 06.27.2007 12:14 AM

Yea you could put 16 cells on the 1y for fun, but I wouldnt do anything more than a couple passes before letting the system cool down. The motor will be spinning over 40K rpm and will be drawing alot of amps with that big motor. Stuff will heat up quickly. But for a speed run or 2 and then let it rest it shouldn't be a problem.

Just keep a close eye on temps when you do it.

I personally get tired of that style of runnig very quickly, but occationally its fun to really pants someone who has a nitro that they think is fast.

E-Maxx King 06.27.2007 01:31 AM

So gearing im guessing 51/16 and 51/18 on 40 mashers? And what else will I need? Axles, Centers, Idlers, 1/8 diffs, 1/8 bulks, and pinion spur.

I wish more people could help me out tho. :(

jhautz 06.27.2007 01:46 AM

With heavy tires like that you will probably be better off with the 51/16 gearing. But you can feel it in once you get it set up. 18T is not out of the question depending on the voltage you run.

If you check the store Mike now has 17T and 19T pinion gears listed. I dont know where he found them, but I'm glad he did. (Just ordered me a set the other day) Sure makes gearing alot easier 1 tooth at a time.

I am not responding to a thread with 'HURRY, or QUICK' in the threadname.

And with post #25, the 'most meaningless post award' is already given for this month..

E-Maxx King 06.27.2007 03:16 PM

Ill be running 14 cells so 16.8 but more like 19 volts off the charger. Um would it be better to do a revo? Can the stock diffs on that handle the power? Should I start another thread that says "what do I need to run a NEU 1Y?" Also how do you know how mush your tires are going to expand? Is this motor better then a Bigmaxximum? Cause I saw how cool the 40 mashers look when they expand! :) :) :)

Serum I love that revo your working on! Thats sick! How much does it weight? Is the revo more durable then the e-maxx?
