    2s or 3s for racing?

    What's up guys?

    I'm looking to replace the esc/motor on my slash with a brushless...

    I'm stuck between the sidewinder and the mambamax.. now as far as I know the only difference is that one supports a 2s and the other a 3s, right?

    What do you guys that race use? I'm leaning towards a 2s but don't know what sure.

    Thanks.

    The mamba max also has a built in USB interface for updating esc firmware and throttle profiles, etc, etc.

    For racing I would use a 2s. A 9 cell nimh is uncontrollable in a slash and the 3s will be even worse.
    I tried being reasonable, I didn't like it.

    The sidewinder's usb interface is not built in, you need to purchase the castle link to utilize it.

    Agreed. 3S lithium on a track appropriately sized for a Slash to race would be excessive. I reach exactly 30mph on pavement (geared very very low) with a 2S, which translates to more than enough speed on a dirt track.

    I would also highly recommend Castle's 4600kV motor for this truck.

    Hmmm.. does the mamba come with the cable?

    Any reason for the 4600 over the 5700?

    From the pics I have seen it looks like a standard micro usb connection. Same cable I got with my camera, my motorola phone, and my laptop external hdd.

    yes/no?

    Yes, Mamba Max comes with a USB cable. But if you already have device using the same connector, you can use it, too -- a cable's a cable.

    The 4600 has more torque than the 5700 giving it more pushing power to get this larger truck moving. Aside from the obvious Maxx and Revo, it's the heaviest of the electric trucks. You won't have to gear it quite as low to get good performance/moderate temperatures as you would the 5700. If/when my 5700 dies, it'll be replaced with the other.

    Yes it does.

    As for the sidewinder, the castle link, which you have to buy, is an adapter than plugs into the receiver wire and has the micro usb on the other end as seen in this picture.

    Get the 4600. I run the 5700 and it's hard to keep the temps down on 3s. I've order the lower kv VXL motor. Should be here in a few more days.

    I'm shocked you guys are suggesting the 4600 over the 5700, but since I know nothing about the two...

    Anyway.. my goal is to make my slash faster, but not 3s faster, ill leave that for my rusty... I want it so if I decide to race my slash, I'll be ready .. which is why I was leaning towards a 2s lipo and sidewinder...

    About the cable.. would this cable for my cam work in it? I would really hate to waste 25 bucks on a cord...

    Ya, that's the same USB connector.


    I tend to see the kV indirectly proportional to the weight of the RC its to power. If you look around in the ERevo forums, the only thing any of them talk about are which brushless motors to use. Recommended are Neu motors that are in the 2000kV range. Those trucks are close to 10 pounds.

    The Castle Creations 7700kV motors are great for on-road racing cars because they're so light.. and higher speeds are more critical to win the races.

    Mind you.. this isn't a rule, obviously. To me, it's just something that makes loads of sense.

    The reason I suggested the 4600kv is becuase I wish I would have choosen it instead of the 5700kv. The 4600kv motor should run cooler. I ordered the vxl(3500kv) motor to eliminate my heat issues all together. Hopefully I don't have to sacrifice much top end. If you wait a few days I'll report back how it works out.

    Someone running the sidewinder in his Slash on the board. He's got the 4600 motor on it. No heat issues for him either. Looks pretty fast too from the videos.

    The 4600 can be geared for anything. It can take it. On 2s lipo mine is about as fast as my XBR 8.5 on 2s lipo. Plenty fast for racing!

    I've decided to get the Sidewinder / 4600!

    Thanks alot for all of the help guys.. so if I'm correct, the 4600 will still give me full power from a 2s lipo and will stay cooler?

    2s will be fine. I think you have made a good choice.
