Which Brushless motors ?
 

Hi,

I'm sorry for my bad english, but i'm french and I don't speak and write english very well...:o

Which brushless motors are the best for an e-maxx ?

- Plettenberg MAXXimum
- Plettenberg BigMAXXimum
- Hacker C50 9L
- Hacker B50 8L
- Lehner Basic XL 3100
- Lehner Basic XL 2800
- Feigao 9L

Thanks for your answers...

Each of those motors is a very nice motor for the emaxx, although the Lehner Basic XL 3100 may run a little hot, depending on the number of cells that you are planning on running. Supposedly, if you have the cash the Bigmaxximum with fan is a really great motor, but then again for that amount, you can get some big motors from Lehner.

Basically, we need to know your cell count and what type of truck you have before narrowing down the best motor for your preferances.

The plettenbergs motors are a 4 pole motor. If you get them you have to get a esc to support that. The hackers and the fiegaos are almost the same motor ( I think).

And welcome to the forum.

I have a full gmaxx truck...

When I'll have my brushless motor, I'll invest to :

- MIP Center cvd set - e-maxx ( here)
- MIP Shiny CVD Kit (here)
- Maximizer 7075 Aluminum diff cups (here)
- Slipper kit Robinson Racing (here)
- Gorilla Maxx single speed ( here)

I run with 14-16 cells (3300 or 3700)

sorry i run with 12-14 cells :o

i would look at the lehner xl2800 for 14 cells. the xl3100 would run a little hot on 14 cells. if it was me i would get a big maxximum.

Why a bigmaxximum ? the lehher is not good ?
How many cells this motor run ?

Does The 3100 XL good with 12 cells ?

Guile the big maximium will need the schulze controler or something in that nature. Price difference between it and the bk is about$150. The motor is another $280 for the big maximum. I don't know how fat or deep your pockets are. But figure some pricing in as well. I ran the xl 2000. It did great. It ran hot to. I was running 18 cells. Motor was to small for the weight and gearing i was running. The lehners are nice motors. You want some awesome power and speed try a 7xl with the 9920.

The Maxximum with fan would work well for 12-14 cells. Or the Lehner Basic XL 2800. Or the Feigao 9L.

Guile,

What is your primary requirement? Are you going to race your e-maxx or bash? You want high speed or low end torque?

You noted that you're running g-maxx stuff, I presume that w/ 14 cells you'll be a bit lighter (weight wise) than a stock e-maxx.

Knowing this will help you determine the best motor/speed control combination for your application.

I sold my bigmaxximum to get a 7XL.. that bigmaxximum is overrated.. (for your eyes only) on 14 cells i would get a 7XL with a 9920.. That is the best money/quality value..

Dafni runs his 7XL with great succes on 14 cells. with the 10L his system got hotter.

I know the BigMAXXimum with fan and his esc are very expensive ! (BigMAXXimum with fan

==> 299.00 $ , Esc Schulze fut-18.97KW ==> 355.00 $ | source : icare-rc)

I want a hight speed and a very good torque ! In effect I run with 14 cells but I can invest to 16 cells pack...

go for the 7Xl and the warrior 9920..

That controller is a good choice, and the 7XL, 10L or an XL2400 for 16 cells. the 7XL is my favorite choice.

I have a friend who run with 9L and it say to me that the 7XL is a little weak for an e-maxx...

Weak?!? The 7XL is longer than the 9L, so it can't be weaker. It is slower, but it makes up for that with its higher power capabilities.

a 7xl is stronger than a 9l and geared right will toast a 9l.

The lehnher XL 2800 or 3100 is also a good choice or not ?
What is the better between the feigao 7XL, 9L, lehner XL2800, XL 3100 ?

In terms of what? The 7XL is the most powerful, but the XL 3100 is the fastest. The 9L might have a little more torque than the XL 2800, and it has a 5mm shaft (the XL motors have a 3.17mm shaft).

In effect, I want to buy a motor which have a good compromise between speed and torque (fast and many torque)

I say the 7 xl is a good motor. Weak i don't think so. It would pull wheelies at 50+ mph. That is how i crashed mine. I run a 14 l and it don't have near the power the 7 xl had. If you get the 7xl and run it with a 7020 the control will hold it back some. The controller will not last but so long because of over load.

7XL get's my vote..

I would say dafni's to there serum.

For ultimate reliability, the 7xl, warrior controller and rc-monster heatsink/clamp is the best dollor for dollar performance buy, in my opinion(I do have a bit of experience:)). The Lehner basic xl motors are also excellent motor, with impressive runtime and power output. They will run a bit warm in a particularly heavy truck, though, while the 7xl can handle the heavy trucks much easier. On 14 cells, the 7xl is very happy to deliver power and speed(as much as the batteries can deliver) without overheating. There are better motors and better controllers (BK has several upgraded controllers, and Lehner has many high end motor in their line), but none that offer the price/performance ratio of this combo.

Amen..

I go along with that as well. amen

thx for your answer mike !

Right now i'm using an HVmaxx setup with two 6cell 3300gp's. My truck weighs a tad over 9lbs with batteries installed. I've been racing it a bit at the local track but I have only Nitro's to compete against. The A mains run 15 minutes and what i'm wanting to know is what would be a better brushless setup to compete with these nitro guys. If i gear the HVmaxx for longer running, i can't keep up with them, especially on the straights. They get to pit but if i pit to change batteries, i lose. Is there a system i can replace the HVmaxx with that will give me the runtime I need for the A main and the speed to keep up? I'm soon going to be getting a set of the Intellect 3800's and will most likely use 14cells. I'd like to stay around $300 -$400 mark for the brushless.

I don't know why people are so obsessed with the Maxximum? They are way too expensive for what they deliver.

I am also suprised no one said anything about the Hacker C50 range, I know someone with a C50 10L on 16 cells it beats any nitro! So much power and so much speed, although low runtimes.

I think the 9L is good for 14 cells. :)

a big motor runs nice and cool..

You are right about the maxximum Nick!

i personally perfer the the lehner over the feigao because a lehner with the same kv rating as a feigao has more torque and has longer runtimes because they have a higher efficiency rating as well as a screwed on endbell so you dont have to worry about the can popping. if you were gonna race or just want the best i would go with a lehner. the xl3100 is what i have in a 8 lb e-maxx and it is the fasted thing i have ever seen. i can gear it to do 60 without a problem. with the right cell count the lehner will provide excellent torque as well as speed. honestly i dont think torque should be a big concern with brushless unless your truck weights as much as a hummer.

@squee; the lehner XL serie hasn't got the torque of a feigao L series. It takes a bigger lehner to get in that torque range.

How much cells are you using to get your XL3100 powered maxx to go 60 mph?

It was a 9L I compared it against.

On the 9L I had a hard time getting the gearing right.

Yeah, Nick, the 9L is a good motor, too. Fast as heck, no doubt. I just like the 7XL better.

Plettenbergs are really overrated, IMHO. I would take a high end Lehner over a Plett any day. But for now the Feigao / Wanderer XL does a perfect job for me.

I agree..the 7XL and BK9920 .... My vote for sure.... my 7XL runs cool on 12 Cells... at 18 cells and a fan it only gets to about 47 degrees celcius.... and it's moving a 16Lb LST.... The best BANG for the BUCK, no doubt...
