mamba max brushed
 

will this work:
mamba max esc
4s 3200 orion lipo
brushed 550 size motor edit: its a 12 turn.:D
do i need ubec?
thanks.:D

i wish i could help but i just realized how many :D you have in your post and sig lol wouldnt a regular brushed motor get pretty hott when using lipos? i would think so because even my mm 5700 gets pretty warm when using 7 cell batts.

but its a brushed motor made for 14 volts tmaxx.

well it should work no problem....what motor is it?(dunno about the bec)

trinity big block.

Aren't those motors known to wear out in like 2 runs? I have heard that info from alot of people too...

Bye:018:

dont know, but people tend to say that of a komodo dragon aswell and you can run it 10 times without cutting the comm.

only 10 runs? why wouldnt you juyst stick with the bl motor...?

i love doing some motor work, cant do it with BL. to bad.

You could get a purple fegao, and polish it till it's silver.. That's some work too.. :p

Just get a brushless motor, no matter what you do with a brushed, brushless will outpreform it in terms of efficiency and most likely torque..

With 4S you need am external BEC (or a loose battery)

I would say you need a ubec cause it is 4s lipo.
No matter the motor.
I have read that some of the crawler guys really like the brakes of the mamba
max esc. They say they work real well.

i actually like the handling of brushed better.
have 2 mm's and they dont drive as good as brushed motors.
i hope i dont get flamed for saying this:002:

What brushless motors have you got as reference then?

mamba max motors. in 1/10th cars ofcourse.

'like the handle of brushed better'

Odd..

well ill admit when i first got the bl system i didnt like the way it drove compared to the brushed motor. it like cogs and isnt as respnosive and what not but after tuning it to my specs it now runs AWSOME!

gl getting what you want!

what batteries are you using? these might be a good reason for a setup not feeling responsive. The MM 5700 is a relative smooth ride.

Thats the first time i herd that someone still likes brushed better then BL?

weird huh
:032:

It is different strokes for different folks.
It is like nitro and electric thing.
Not everyone is the same.
If a brushless is set up properly it runs real smooth or should.

I raced with my MM and Orion 12X2 and it worked great... better than the 4600 because I never got that dang glitch all night. :)

It's a great brushed speedo, imo... based on the one day I ran that combo.

Fro anyone running a stock emaxx... with titans or whatever.... I think this would be the best replacement to the stock speedo. Not to mention that you could always drop in a Bl motor some day.

i like that idea:D

Good idea GD, but how would you run 2 motors off the MM?

BL is always going to be better than brushed...always...

As for cogging in a BL. Well, thats only in a sensorless system off the line. I was somewhat of a skeptic too, thinking it cogged ALL the time, but after I got my 1/18 Mamba, I was convinced.

It coggs just as you start (If you grab full throttle off the line sometimes it even goes backwards an inch or so before rocketing off), but after you get going, even if you are barely rolling, it is buttery smooth all the up to top speed. And, a 1/18 Mamba is a pretty old ESC in terms of BL technology, the MM is supposed to be a zillion times smoother - if thats possible.

My other system is a sensored system - an HV-Maxx 4.5. Its fast...very fast for my application, in fact. I have to be very careful or else I'll fly off the track this thing is so fast. However, this is supposed to be more of an entry level system, so I can only imagine the power of other systems. This system is by far smoother than my 1/18 Mamba, but thats because its sensored, so it knows exactly what to do.

Just like the stock setup... motors are hooked up in parallel to the speedo.

Oh ok! Somebody should try this out.

Don't have got brushed motors here..

I just tried a brushed silver can 540 motor on 3s lipo with my mamba max. It's about the same as a stock motor, but it heats up alot. I'm willing to bet that the 5700 geared really low on 2s or 3s lipo will be a better setup than the two brushed motors on 12cells or 4s lipo. Even better, the 4600 on 12 cells.

You need to try a MM and a 7, 8, 9XL motor. Believe me,i thought there couldn't be anything to compare. I was running the 6.5 but the 7 and 9xl on 5s lipo are awsome

When he and I are able to meet up, he will be able to compare his HV 4.5 on 4s Lipo to my 7XL on 5s A123. I'll see about getting some video :).

I will be carefull with torque...

P.S Recently got plettenberg 355 for testing...

for me, its like mamba max is an on or off motor. so far it does seem like that.

Artur; take a BL motor of that size, and see how that preforms in terms of torque.. but i covered myself with this sentence 'and most likely torque'

Largest brushless motors i know of, are in a 933ft tall ship, they actually push the entire ship.. All the fossil fuel engines are used to feed the generators. talking about lots of megawatts..

:rolleyes:

Rene, you safe with "most likely" just sometimes it is enough for somebody to make wrong decision based on such comment. Let's be true to the physics and mechanics, its all about maintenance and lifespan, but if you want torque then brushed motor is the one you want...
So back to RC that is why there are lots of guys here and there still enjoying brushed setups, while BL offers power and almost trouble free operation. While it is very difficult to find 550-can with neodymium magnets ... :)

Artur

P.S. 355 has many poles (like outrunner) 3-4 poles covered by one brush at given time, so torque won't be a problem.

i was wondering now if any of you guys have torque ratings of any motors?
i know some of the trinity's(540's)
it would help me alot if i know what i would need to push the 4 kilo trucks around.

It is quite simple Kt=(Kv/1000)*1.345 (oz-In/A)

Artur

hmmmmm
so how would i convert oz-in to newton-mm then?
thanks.

100 oz/inch is about 71 N/cm

1oz is about 28 gram, and 1" is about 25.4 mm..

ok, i found a converter online.
i calculate kt value of mm 5700 and with that i do some more work and get to 1600 newton millimeters @ 30 amps. a average 19 turn has 130 Nmm of torque at unknown amps.
