    Q's about MMP 2400 SCT system

    After having problems with my vxl I just had a few questions about this system before I bought it
    1. Out of the box it does work fine with the rest of the electronics? No need for an external bec
    2. Does the esc automatically recognize the batteries voltage and knows its lipo so lipo cutoff is activated?
    3. Any tips on how to mount the esc
    4. Gearing for good speed, torque, and relatively cool temps.
    Have you had any problems or minor issues with the system

    Thanks for the help and I hope this could help others with questions too.

    1. works good.
    2.yeap it comes on autolipo mode, you probably want to raise the voltage cut off, it's set at 3.2v x cell
    3.I cut a piece of lexan drill a hole use some small screws to attach it where the old esc was and use velcro to mount the MMP, or get a snappy esc mount from ebay
    4.A good start would be 54/17 depending on your drivings conditions, but I'm sure you can gear it higher, I'm very happy with it also have it on my pede 4x4.

    PS. You need at least 3s lipo to wake up the beast.

    Thanks for the help and yes 3s will be used, what would you recommend setting the voltage at, and I might do 54/18 because I have the 18t pinion that came with my slash

    I have it at 3.4v x cell, yeah sure 54/18 is fine.

    If you get the snappy mount which is a good investment. Don't forget to buy the receiver box to relocate yours to the front. Traxxas part #3628. I'll post a pic of what it looks like in just a sec.

    if you use velcro there in no need to move the receiver box, also if you decide to move it you can use the stock one mounted sideways, only need to drill a new hole to secure it on the chassis.

    Also would like to know how the Mamba Max Pro tells you that you have hit low voltage, like how the vxl cuts to 50% throttle

    No need to move the RX box with the Snappy mount, at least I didn't. You will want to run a Kingheadz motor mount or something like. At the least get the aluminium bearing adapter for the slipper clutch. I'm geared 18/52 running both stock size and 1/8 buggy tire's. it is insanely fast!

    I have mine mounted to the chassis with a clear double sided tape. Works very well and stays put even on hard crashes.

    Either way I would relocate the receiver. It's a very tight fit leaving the receiver box where it is, and the 2 days I ran with just using Velcro my esc got banged up a bit. To each his own though.

    Is there an advantage for mounting the esc next to the motor?

    If someone has to mount the lexan to the chassis, should he mount the lexan/esc to where the new receive box would be instead(so the stock receiver box stays where it is)? Am i missing something?

    For example here is what i have for now with zip-tie because that's the only place can be ziptied at the time, will do the lexan with Velcro later:


    in this pic, the motor and the esc is far way apart that:
    Advantages:?
    1. The esc can avoid the heat from the motor
    2. The wires are easily to be managed, no worried of melting from motor heat.
    Dis-advantages:?
    1. If someone decides to shorten the wires
    2. the front truck could have more shock from frontal impacts/crashes than the middle of the chassis?
    Thanks for any clarifications.

    If u buy the field link for it it comes with the USB cable needed and you plug the USB into the field card then plug the field card into your esc... If that makes any sense

    This is my set up i didnt need to drilll any holes i used the existing holes for the VXL
    to mount my STRC esc mounting plate. The trick to getting both screws to work is to
    tighten each screw alittle at a time going back and fourth till the plate is snug. I tryed
    to use the velcro method but after a few wipeouts it kept popping off. Then i tried the
    3m plastic velcro strips there is 2 in a pack all you need to do is cut one in half put one
    side on the mounting plate and the other under the bottom of the ESC line it up and
    puch down hard. Since i install it this way i have never had any issue with the ESC popping
    off. PLus it Gives the setup a cleaner look. I only bash but im Geared at 22/52 running
    on 3s no heat issues what so ever. the low voltage is set at 3.5 aluminium bearing adapter
    is a must ,Kingheadz motor mount or something like it that has the 10x19x15 bearing
    helps out alot. I Love this system in IMO the MMP 2400 is the best upgrade that i made to
    my slash. As you break parts then upgrade you appreciated your slash so much more
    but mostly its a mojor learning experience.

    Good Luck
