Tomorrow Im going to the LHS to get a brushless system, and Im deciding which one to get. I can afford the MM, but I dont know if I need it.

I have a Losi Desert Truck and I want more speed for when I go to the sand dunes, but Im not sure ho wfast I will go with the MM and the SW with my current setup.

I am just running a 4200NiMH with my DT so Im not sure if the MM make a big difference over the SW with a 4200 NiMH.

What would you recommend I do?

I want to eventually get a LiPo but Im not sure when that will be.

How much faster will the SW or MM make my DT?

sorry no idea i am affriad

Well Chris_RC told me that the Sidewinder has 66% power of a Mamba Max, so if you want the power, get the Mamba, If you will go Lipo, the get the 5700, that will make your 4200mah, (7 cell?) Which cell Lipo do you want to get? if you will only go 2c, get the 7700kv, that is the most power, but the lowest voltage youy can put in it, so you need to figue which works for you, if some reasom ya wanna go slow, get a Sidewinder 5700kv, if ya wanna go fast and gonna go 3c lipo, Mamba 5700, if you wanna go fast without payin the pric of expensive lipo, get the 7700, if you can control it, if ya cant, then get the 6900

Chris_RC

the Sidewinder 5700 isn't "slow." But if you want to run 3c lipo get the Sidewinder 4600.

clamber

Its a 6 cell DTX 4200. And If I get a Lipo it will be a 2s.

I actually had this same question and I called Castle about it. They said that unless I wanted to use 3 cell Li-Po on the 5700 kv setup I would see no benifit from the Mamba Max other than the built in USB port. While the Mamba Max might be able to handle more power than the Sidewinder, the 4600 or 5700 kv motors on 2 cell Li-Po won't pull any more than the Sidewinder can handle anyway, so the MM isn't needed. There will not be any speed/power benifit from the Mamba Max on a 2 cell Li-Po or below. This is according to Castle Creations.

Because of the increased power requirements of the 6900 and 7700 kv motors, they are only available with the Mamba Max.

However, the Mamba Max does have the built in USB port for programing. The Sidewinder requires the Castle Link in order to program certain settings. You can program the main things without it, but if you have the Castle Link you can program all the same things on the Sidewinder that you can on the Mamba Max (again, according to Castle Creations).

Chris_RC

So if you get the Sidewinder 4600 and plug in the castle link it will have the asme power as the 4600 Mamba Max that comes with the castle link?

What is the speed/power difference between the SW and MM? NONE! ESCs don't make power, motors do. The more powerful motor you choose, the more power you'll have. The only thing you need to worry about with the ESC is that it can handle the current demand of the motor you choose. If the SW can handle it, the MM will not be a faster setup.

BigTb17

Yes.

The Mamba Max is capable of handling higher amperages than the Sidewinder. But if the motor you are using doesn't draw any more than the Sidewinder can handle, there is no need for the Mamba Max. I called Castle Creations just to see what they had to say about it. I said I was looking at the 5700 motor and they said that if I wasn't planning on using a 3 cell Li-Po there would be no benifit from the Mamba Max. With the 4600 motor you can even use a 3 cell with the Sidewinder. It simply wouldn't have the USB built in.

With the Castle Link you can program all the same settings on the Sidewinder that you can with the Mamba Max. This much I know because I know someone with both ESCs.

Lets keep it simple
no more than 2s=SW
going 3s=MM

Right?

The SW is basicly A lower voltage handling version of the MM? Minus the castle link being included

clamber

Ahh, so the only benefit of the MM is going to come if youre using a 3s. And in that case you will ha a lot of power. But for me just using a NiMH batt and maybe a 2s later on then the SW is perfect right?

Now comes the question of what to get. 4600 or 5700? Which one will give me the most power with my NiMH?

clamber

According to this it says that the MM is more powerful if using a 6cell nimh.

BigTb17

I don't see where it says that. Where on there does it say that? The only thing I see on that chart is what I've already said. You can only used a 3 cell on the 5700 with a Mamba Max, and you can only use the 6900 and 7700 kv with the Mamba Max. It doesn't say anything about the 4600 or 5700 being faster with the Mamba Max on 6 cell Ni-MH. In fact the chart shows the Sidewinder and the Mamba Max together in the same boxes, with the same speed ratings for all setups on the 4600, and all setups except the 3 cell with the 5700kv. Please point out where it says anything about the MM being more powerful using a 6 cell, because it seems to confirm exactly what I (and bhcvc) said.

BigTb17

The Sidewinder is a lower Amperage handling speed control. The problem is that with any given motor the amperage will go up as the voltage goes up (Ohm's Law). So that if you are using the 5700kv motor you cannot use a 3 cell because the amperage load may be too much for the ESC to safely handle. You can use a 3 cell Li-Po with the Sidewinder with the 4600 kv motor because the amperage draw with that motor is less than the 5700kv. Now, ESC's do have a voltage limit, but the Sidewinder can handle 3 cell Li-Po, but only with the 4600 kv motor.

I meant that the 7700 is 10mph faster than the 5700.

Should I just get the 7700? And then when I upgrade to a 2s the 7700 will work fine with it right?
Is there any downside to having a 7700?

IloveMYxt2

Why not just get a 3s lipo in the near future? If your going all out with a MM 7700, then do it right.

From what I remember, the 5700 with give you some more punch off the line over the 7700. The 7700 will give you higher top end, if you can control it on a light truck like the Losi. I was looking into this stuff for my buddy as well. And heres another thing I heard. With a 6 cell Nimh, your going to get 7-10 minutes ride time, if even that. And Lipos are pricey as well. So after all this research, my buddy ditched the brushless scene cause he didnt want to pay close to 400 bucks and just got a nitro buggy.

clamber

Damn, I dont know what to do now. I guess Ill just get whatever and just upgrade to a lipo later like I planned.

Any other comments anyone?

The Hedgehog

The 7700 would be terrible for offroad use. Just get the sidewinder 5700 and be done with it. Its so cheap.

clamber

I guess Ill do that.

rschoi_75

good advice

willdawg

Ya, I might get that instead of the Mamba Max.

clamber

I got the SW 5700! Yay Im so happy!

Now I just gotta figure out how to set the slipper.

Chris_RC

Do you know how to set the slipper? Because you were confused. [&:]

Hi,

I just purchased an e-Firestorm for my 5 year old son. I figured since all his cheaper RC cars broke down it was just a good idea to purchase a single more expensive car that can get replacement parts. The thing is, I love this car

So I started reading on how to upgrade the car to brushless but I´m a confused. Is there a FAQ somewhere that explains all these terms? LiPO, 2s, 3s etc? I also have the following questions.

If I wanted to upgrade to brushless but were thinking more bang for the buck and runtime, ease of use than maximum performance, what should I get?
What is the difference between 2s and 3s?
What else do I need to purchase if I go for a brushless Combo (ESC and Motor)? Connectors as far as I can tell, anything else?
What do I need to change (gearing, spurs and terms I get lost in)?
Can I use the e-Firestorm with brushless to drift (with approriate tires)?

Thanks in advance for your assistance.


Rgds,
Caaine

a MAmba 5700 or a Sidewinder 5700,and look, just gear it down by what you can tell on the first few runs, every minute, check the motor and ESC temperature to see if they are really hot for what you are doin, if so just gear it down, I dont know about the Tires, and you have to get connectors for the Battery pack on the BL system. I hope that answered some ques, and look, when gearing down, you gear the pinion down, and the spur up!
