    After market esc and motor

    How can I find out which esc and motor will fit my merv? Mmp seems very popular but overprice for 1/16 scale rc car.

    go with the new water proof castle sidewinder 3 it is only $67 and lots of people use that on their mervs
    With great brushless comes great responsibility.

    These are for 1/10 scale. Do these require bigger batteries? What about run-time?

    they do not require bigger batteries, but they can take them, but they do not fit

    You should run the best batteries. Will still have quite a bit of voltage drop but makes plenty of extra power to make up for it!

    I looked the spec for mmp, and it can goes up to 6s lipo. So, I don't need 6s for my merv. Only 3s is good enough?

    How these compare to stock esc and motor?

    3s is good enough but the esc is much stronger and will run cooler. No comparison from stock to the mmp

    Maybe I`m wrong but I understand that sidewinder 3 is just waterproofed sw2. I got sidewinder2 for 44$ and I waterproofed it . I don`t really see the point spending 80$ for sw3.

    Sorry guys, I guess I'm going to ask dumb question. With mmp and sv3, can these go up to 50 mph like the stock only with 3s?

    The MMP is awesome +1 @50toGo the only issue is bashability.. You'll loose the waterproof feature unless you youtube it and waterproof it yourself.. if it's for street runs go for it and make sure you have some strong CVDs, etc and prepare yourself for some insane speed.. It's like throwing a 600RR Honda motor on a Mongoose BMX bike lol..
    Whatever I just said.. I'm probably wrong..

    I happy with top speed on my merv with stock esc and motor, but the motor gets pretty hot. Planning to upgrade, soon.

    usually the esc is the weak point, the motor is quite robust.
    if the motor does get quite hot, you should lower the pinion gear or increase the spur gear.

    One last question. I'm planning to get the combo. The mmp can handle 25 volts, but motor only handle less voltage. If I use 25 volts, will it kill the motor? Thx guys.

    Yes you will burn the stock motor with that much voltage..if your talking about the 1/10 castle motor that comes in the combo, I'm not quite sure but it might do the same

    In my experience, the stock esc is running solid. It doesn't over heat or thermal shut down. I'm just worry about the stock motor. It overheat several times. I switch smallest pinion gear and larger spur gear. These help a little.

    Might just have a defective or damaged motor. Usually tougher then that!

    I received this letter from CC headquarter.

    "It is the motor, not the ESC that determines how much voltage you can run in
    a power system. If you over-volt a motor it will over-speed and possibly
    explode. When it does this it will also take out the ESC and possibly the
    battery. Go with the motors voltage limit, not the ESC. "

    Is it me, or sounds funny?

    Does not sound funny at all.
    But you do need to consider the ESC's limits as well as far as voltage goes.

    If the ESC was properly matched to the motor you should not have any concerns with mAh or C rate, just voltage.
    Whatever it is I just typed... could be wrong.

    if a motor is designed for a max 60,000 rpm and you overvolt it to spin 80,000 it can come apart not to mention damage the bearings if it doesn't.
    on the esc you can run the biggest strongest esc and the motor will only draw what it needs.unless you over volt it

    read here: http://www.ultimaterc.com/forums/sho...d.php?t=121843

    what batteries are you planning on running? how do you plan on driving? also its doubtful your stock motor 'overheated' (as in shut itself down, which is how i read it), thats what the esc does for protection. the motor will get too hot then destroy itself tho. do you have a temp gun? maybe possible youre motor done?

    if you are gonna keep the stock motor, which is a pretty good motor, look up the specs and plug em into the above page. i think it might be max 3s.

    on to my main point: i went with a sidewinder, cheaper and easier to fit, a good direct replacement for stock esc. i see the mmp more if want high volts to do crazy speed runs, which will require a new motor. mmp overkill if youre keeping the stock motor.

    I looked the speed calculator, and it doesn't look very accurate.

    Never mind. I inputted the wrong setting.
