READY 2 BUY....Need opinions please.... - RC-Monster Forums

I'm finally ready to buy my brushless rig for my Supermaxx E-maxx and want your opinions. Especially from RCM Mike, JHAUTZ, and SERUM (plus anyone else with experience with these products)

I'm looking at one of the two packages:

NEU 1515
UBEC
Mamba Maxx ESC

or

FEIGAO 540C 8XL
UBEC
Mamba Maxx ESC

This will power my Supermaxx Equipped Emaxx. I'll be using GP3300's in 7 or 8 cell configuration (14 or 16 total cells so 1.165x14 = 16.31v or 1.165 * 16 = 18.64v).

I like the NEU 1515 but would rather keep the additional $190 in my pocket if the performance difference between the NEU and the FEIGAO is comparable. Will I need fans for the Feigao? The ESC? The NEU?

I'd consider a Lehner to if it makes more sense.

I'll be converting to Li-Po at some point, probably when the MMM ESC shows up and I can run 6S.

So there it is. Now I need your feedback so I can give Mike an order this week.

What say you????

Jhautz did some testing and found that the 19xx LMTs did much better with the MM than the Neu motors...

Procharged5.0 · 12.19.2006, 07:00 PM

Can you explain "Better"? Smoother operation? More Speed? What???

BrianG · 12.19.2006, 07:03 PM

Sorry, I thought you might know the thread: http://www.rc-monster.com/forum/show...9&postcount=30

The Neu cogged a lot under hard acceleration, but the LMT was smooth. There's even a video in that post...

I like the lmt motors alot. The neus are nice as well. I have seen some differences between the 4 pole and 2 pole motors in smoothness.

Hey CHC, what esc are you running the neu's with?

jhautz · 11:44 PM

If you are planning on running 16 cells on an alloyed out Maxx, I'm not convinced tha tthe MM is the right choice. I think the MM will do nicely in a 8.5lb buggy that is intended to be geared for under 40 for the track, but the bigger/heavier vehicle will draw more amps. The last thing you want is a ESC that is running ragged edge. IMO 16 cells in a maxx size vehicle is ragged edge for the MM. With the little testing I did with the MM I'm not all that thrilled with it as a large scale ESC. DOnt get me wrong...Its amazing that it can do what it does, but I still think you are better off with a speedo that was intended for the job. Read the thread that Brian linked to about what I saw on the MM/Neu combo.

Think about your options for the $ you have to spend.

You could go with the cheaper motor and take the extra $190 from the motor and spend and extra $140 and upgrade the MM to a Quark. Then later when you want to you can upgrade to any motor you want. The quark will run them all and its is still the smoothest esc Ive used. And your still $50 ahaed of the Mamba/Neu combo.

Another thing to consider might be... Right now for like $15 dollars more than the Neu 1515/Mamba combo you could get a Lehner 1940 and Warrior 9920 combo. This would be a killer combo in an emaxx. Heck with the 9920 being only $150 right now, once they go back to regular price($200) you could probably get your $150 back for it by selling it ''gentley'' used on ebay. And then get the MMM when it comes out.

EDIT: Sorry for the book....But you asked.:018:

Looks like I'm not the only one with long explanations! ;)

I know... I tend to ramble:010:

BrianG · 12.20.2006, 12:11 AM

As do I...

jhautz · 12.20.2006, 01:15 AM

Just an FYI... Total coincidence but I toasted my Mamaba Maxx on 5s tonight. First pull of the throttle on a fully charged 5s pack running a Neu 1515. It was just a light easy start not even a hard throttle pull. Its just not cut out to be reliable on that kind of voltage.

Now I really wouldnt recomend the MM for a 16 cell application. 16 cell is even higher voltage than 5s.

Serum · 12.20.2006, 03:11 AM

Pushing the mm with 16 cells is something i would not do.

i have got a Neu and a Lehner, and the Lehner is topnotch stuff. (as is the Neu) since the Lehner is a 2 pole it's easier to be controlled than the Neu for the Mamba Maxx.

If you are planning on running 14-16 cells the 9XL would be a good choice. My 8XL gets relative hot on 16 cells. Doable though, but cooler is nicer IMO.

Perhaps you are better of with getting an MGM16016 controller? or a 9920 with an LVC.

12.20.2006, 11:10 AM

I can highly recommend the MGM, I have been running it with 5s on a 7xl with no problems at all. The built in voltage cutoff works well too.

Procharged5.0 · 12.20.2006, 11:19 AM

I can run 12, 14, 0r 16 cell configurations. I built (4) 6-cell packs but have the cells available to make them 7 or 8 cell packs.

I don't want to fry the MM and I know that my 16 cell config is .15v over 5S. I like the programmability of the MM and that its US made but maybe it's not all that necessary to have the PC programmability. OR maybe I should just run 12 or 14 cells.

What is the difference between a LMT 1940 and a LMT 1950?

I have the cash now to do this and want to do it right so the Lehner is an option but if I can get a nice combo without dropping $600+ to do it that would be my preference.

BTW, LONG responses are welcome. I'm desperately seeking valuable advice & input!
