    My 4S Powered Slash

    I got the chance on Friday to throw together my 4S powered Slash. It has the following gear installed:

    ESC: MMM
    Motor: Medusa 36-60-2000
    Lipo: PolyRC 4S 25C 3700mAh
    Rx: Spektrum SR3500
    Tires: Pro-Line Switch
    Wheels: Pro-Line Epic
    Gearing: 18:54 32P

    I also have a new Pro-Line Hardcore body that has yet to be painted that will go on it in the future.

    It's spec'd as 30mm, but fits just fine with a 3mm spacer under the rear hold down bracket and a single turn out of the front post.

    I've actually only got it geared for ~46mph. I've got lots of room to gear up if I want to do any faster speed runs. However, with the speed it does now, it's hard enough to keep straight and on all 4's.

    Is it just me or does everyone feel like they have to throw money at their trucks? Upgrades are great but there is no reason to put a mmm and 4s lipo in your truck and gear it down so low that it tops out at 46mph.We all know that 46 is attainable far cheaper with far fewer volts. The same size 2s lipo would have twice the run time. Not to mention it is a 2 wheel drive off road truck and hard to control above 40mph. If you want to set some speed record for a slash then you might be able to justify the overbuild, but otherwise it is just classic little man syndrome. Does your street truck have chrome bypass shocks too?

    Is it just me or does someone have some unaddressed issues that should be discussed with their therapist? Why do you care how much money anyone chooses to spend on their toys or how they choose to modify them? If you don't like it then keep it to yourself.

    BTW: not all slashes are used offroad or exclusively on dirt which may require them to have different tires/motors/batteries then what you happen to feel is appropriate or financially reasonable.

    I didn't have to throw any money at it. However, this is one of my hobbies and I'm inclined to do what I please with my disposable income.

    Who needs a reason to do anything to their vehicle? It's personal preference that I run it this way.

    "Far cheaper" is a stretch. This setup was not much more expensive than a MM combo and a good 2S Lipo.

    What I paid:

    MMM $150
    Medusa Motor $118
    Lipo $118
    Total: $386

    A good 2S setup:

    MM Combo $185
    Trakpower 2S 4900mAh Lipo $119
    Total: $304

    I hardly see where saving $82 makes something far cheaper.

    That's a load of bull. If you assume the same power on 2S as I have on 4S, a 2S pack will actually have less runtime.

    Example:

    Avg of 150W in each system (a decently realistic average value)

    2S will draw ~20.3A Avg
    Given a 5000mAh Lipo (assuming usage of 90% of capacity), runtime will be roughly 14 1/2 minutes

    4S will draw ~10.14A Avg
    Given a 3700mAh Lipo (assuming usage of 90% of capacity), runtime will be roughly 19 1/2 minutes

    The truth is that a 4S system geared at the same speed as a 2S system will always be more efficient given that the motors are of equal efficiency themselves.

    Yep. What's your point?

    I certainly have no little man syndrome. I could care less who likes or dislikes my Slash. The whole purpose of it is for me to enjoy driving it, not you.

    No, my stock daily driver has nothing of the sort. About as extravagant as it gets is when folks driving behind me can see Sesame Street playing in the flipdown monitor. My 2yo daughter is quite the fan of Elmo.

    I certainly do apologize though that you somehow feel jealous or inadequate enough to have to post such things you assume about my vehicle. Perhaps in the future you might want to refrain from basing a judgement based on one's personal preference.

    To a point I agree with Zachandandy. I also understand that "too much is just enough." Its a relatively free country you can blow your money on whatever you want.
    What?

    I believe in getting how you want no matter how much it costs. I've got an electric 4-Tec that I probably have close to 2K in which is an obscene amount of money for a car that I barely run. But you know what im happy w/ it and have no regrets especially when im out running it and some dude comes up w/ his little radio shack deal talking smack and I show him what a real RC will do.

    Isn't our country wonderful... You are all correct.... skellyo has the right to spend the money he wants on his truck.. Zachandandy has the right to feel it's too much, I'm not really sure why he cares, but hey. I just want to see that Slash in a video, nice work skellyo, I love seeing trucks that are neat and tidy.

    Ohh, and for the record I am jealous!!!

    They didn't pull out of the beadlocks on the first battery pack. I'll be torturing them some more this weekend though.

    i feel this hobby is about escape..and expressing yourself through your truck...if we all drove the same trucks, it would be a boring world..

    i'm also guilty of overspending on all my builds..but it makes me feel good!

    Some people just don't get it, and that's ok. Larry sure gets it though just like me, I make my vehicles as fast as I need to to please nobody but little ol me. That has always been the case and will continue to be in future builds, I'm just thrilled of the options we have today. It's a good time to be in RC.....

    I'm sure at one time people thought 30 mph, or 4wd in a rc were crazy. People doing things like this help the industry evolve.

    Nice build, I'm wanting to get a bl slash as my back up truck. Keeping the fingers crossed!

    My point was nothing to do with jealousy, my point was if I were to want a top speed of 46 I would get a vxl and a 3s and spend close to half. I understand overbuilding when it makes since. If it were me I would throw that set up in something that could utilize all the power(emaxx or erevo). Its like throwing a big block in your minivan, waste of power(although Elmo would be far more entertaining). It's your truck do what you will, just thinking out loud.

    Fair enough. However, here's some reasons why I don't run a VXL on 3S in there...

    1) Much nicer programmability on the MMM via my PC, IMO.
    2) The VXL BEC is only 5V, vs 5.5V for the MMM.
    3) I can run up to 6S on the MMM and use it other vehicles in the future without limitations.
    4) The MMM works well with 4 pole motors, which gives me more motor options.
    5) 1yr warranty on the MMM vs 30days on the VXL
    6) Custom LVC settings available on the MMM.

    Yes, I agree, the VXL will get the job done. However, it will be working much harder than the system I have in there.

    Correction:

    2) Actually, the MMM V3's are closer to 6v and is a switching type...

    Clarification:

    4) The MMM works well with multi-pole, slotted, slotless, outrunners, pretty much anything.

    Addition:

    7) The MMM is firmware upgradeable.

    Just because you run 4s (or higher) with a big ESC doesn't necessarily mean it has to go fast; it can just be a more efficient way to get more power with less current, which increases runtime for a given gearing.

    Nice truck...Have you run 3s on the MMM? I'm debating now between the MM and MMM. If i go with MM it would be the 5700 combo..if MMM then just ESC and use the VXL motor on 3s until i can decide on motor/battery fits me the best.
    Never do anything half fast. Hey Ya'll, watch this

    I have not used it on 3S yet. I plan to run one on 2S and 3S in my other Slash though. I just haven't gotten around to putting the parts in it and buying a 2S lipo for it. IMO, for the money, I'd pick up the MMM over the MM any time I thought I'd be using 3S or more. Since it has the built in switching BEC, it's almost the same price as buying a MM and adding a CCBEC.

    The only damage suffered yesterday was a yoke popping apart on the sliders. They'll soon be upgraded with the new MIP CVD's. Outside of that, the Slash is just stupid tough!

    this is crazy if the guy wants to trick out his slash..that's his business what does it matter how he does it..it's an rc sport and it makes his car personal so get over yourself questioning his motives for his mods. Nice truck skellyo..btw do you still have that rusty I sold a while back...was a FLM one with losi shocks....
