    E-maxx brushless upgrade

    Hello,

    I want to upgrade my e-maxx with a brushless system for about 150 dollars (max. 200), what can you recommend?

    I recomend saving up twice that much and trying then. You can't really get a brushless system for $150 that will work in a Maxx. You need at least a Mamba Max ESC, prefferibly a Mamba Monster Max and at least an XL size motor. Your looking at $300 for the system and another $300 for batteries.
    The answer is no. And yes, mine is faster.

    Those are both too small for the E-Maxx. You can use the Mamba Max ESC paired with an 8XL motor on either 4s LiPo or 12 cells NiMh. That is probably the least expensive brushless system available for the Maxx. If you want the VXL system, you would need 2 of them and build a V-Twin. Many people have done it successfully but I wouldn't recomend it to someone new in the hobby.

    Is the velineon brushless system really too weak for the e-maxx?
    40mph is enough for me...

    Do I really have to replace my batteries? I have 2 4500mah ni-mh race packs

    Ebay is good for me

    Yes the Velineon system is too weak. 40mph is almost impossible to achieve on a single VXL unless your me You will want to upgrade batteries in no time once you get the brushless system because an NiMh pack can't support the amp draw that the motor can pull.
    The answer is no. And yes, mine is faster.

    Are they side by side or shotgun? And what kind of battery bars are they?

    and a v-twin? Do I also need lipo's for that?
    My batteries deliver 40amps...

    Yes, a V-Twin should be ran on LiPos. Here is a comparison for you:

    The first video is on 9 cell NiMh packs. The second vid is on 3s LiPos.

    It doesn't have to go faster than 60-70 kph.
    I just want a brushless system that's just a bit faster than the titan motors...

    What's the best choice of these two?

    1. V-Twin with my ni-mh batts with extra cells
    2. one velineon brushless set with a good lipo battery?

    You can't run a VXL system by itself. You need two of them. If you want to go just a bit faster, get a set of 7 cell batteries and keep you stock Titans. A Maxx really runs well on 7 cells.

    Yes, you can use pretty much any brushed motor with the EVX2. But you will need better batteries for the 700HOs and you still won't have brushless performance. I vote MM/8XL for your application.

    So they aren't brushless?
    And better batteries for more power or longer running times?

    (if one of them has 2x the power of a titan motor it's ok for me!!!)

    he has good motors but they are brushed. if you want to go about 10-15mph get the 700s ont he motor sellection. 970 motors are just as good as brushless about. Thats what i heard

    I use the old e-maxx, so i think i'll take the 970's, but how long will they keep their power? So after how many times do I have to replace them?

    They should be strong, contact dan for more information on them, he will help you out. Ask him if you dont like them if theres any refund policy. I seen alot of good reviews about 970s, and i believe they are just about the same as brushless at only a fraction of the cost!

    This is what happens when I go to sleep...


    Skip the 970s- too big and too heavy- the 700HO conversion gives the same power, in a smaller and lighter package.

    For a simple BL setup, and 40mph topspeed, I highly recommend the novak hvmaxx 6.5 system.

    Read the FAQ for more coherant info on choosing a BL system and suitable batts.

    Ebay is a good place to find all that you need for cheaper.

    I think the 970's are good: a lot of power, low price and strong!
    As long as their extra weight is pulled by them, it's ok...

    lol use those 970's with the battery's you have now and we'll be see'ing a post by you about which batteries to buy.

    I mean no offence, but these guys stopped me from WASTING my money on an insufficent Brushless system. After reading post after post about heat issues and gearing and too small of a motor...etc etc.
    E-Maxx 3905, E-Savage, Summit! Lots of batteries!

    Mamba max, feigao 8xl, CC BEC, traxxas Y-harness wired in series. Cost me about $180, I also run this setup with two 2s 4500 mah aero-nuts lipos.

    Here's my 3905 E-maxx for reference.




    Also, my Maxx gets up to about 45 mph which isn't bad for an MT like the new E-maxx. Here's a video for reference too. http://www.youtube.com/watch?v=JDKhXdBl0Qc

    1+ on the HV6.5.

    Faster, longer run times, easy to install, and you can still use NiMh, but i would make them side by side, stick packs have no place in a E-Maxx.
    Here is my 3906 on a HV4.5 and 6cells sxs packs.

    what will the running time be if I buy a second pair of 4500 mah 6 cell packs with the kershaw 700ho's or 970's?

    And how long will the motors keep their power (when do i have to replace them)?

    Run time = how long is a piece of string? best guess, about 10-15 minutes maybe, too many varibales to be precise.

    The KD motors last for eons- heavyduty motors with heavyduty construction and brushes.

    Do you mean with one or two pairs?
    I can run up to 25 min. with one pair now...

    25 mins with stock titans is pretty good, I'd guess about the same with a single 700HO motor, and 10-15 minutes with a pair of them- not an exact science as always.

    Yay! Did you get those 970s yet? They are incredibly. Yes, they are bigger, and heavier than the 700HO, but the power makes up for it.
    Today, I was bashing in front of a couple of my friend, and parents. They were amazed how fast my 3906 w/ HPI 3300mAh, and Venom 3000mAh (those were just my worst batteries too!) w/ the 970s kit from Kershaw.. And a EVX-1. No fan kit, as my fan JUST died.

    I got nearly 20 minutes.. But it wasn't completely used the whole time. I stopped for about 5 minutes to let everything cool down (was a bit warm)

    I'm going to upgrade my 3906 soon and I'm sure it will be engines form kershaw designs, but I have still time to think about which ones I'll take.

    Grab some 700HOs, if you don't mind checking the ESC a lot to check for overheating.

    700 standards are fine.

    970s are kind of like 700HOs, but doesn't overheat that much.
    Had to stop for about 5 minutes, at the 10 mark. I still had 10 more minutes of nice bashing after the 5 minute break.
