    Cheapest brushless setup for the Stampede

    My nephew's Dad just broke his son's Stampede. One of the copper tabs inside the motor broke.

    I plan to give him one of my own son's Stampede motor, and upgrade this Stampede with a brushless setup.

    Looking for a cheap alternative, running on good 7-cell NiMH and stock gearing. At the moment, I'm considering this:

    Motor:
    EZRUN 13.5T/SL-3650 w/ 3300KV Sensorless Brushless Motor for 1/10 Car
    $39.95

    ESC:
    eZRun-60A-SL Brushless ESC for 1/10 Car (Version 1.1)
    $44.95

    I can also get a combo at $89.95 that will include the program card (although the program card of my ezRun 80A might work).

    Does it seem reasonable?
    Should I go lower or higher kV?
    Would a 35A ESC be sufficient? (I'm asking since a 80A ESC is plenty for my E-MAxx which is twice as heavy)
    Should I change gearing (XL5)?
    Will the stock pinion fit on the motor axle? If not, what should I buy?

    5.5T isn't it too aggressive?
    I thought it was recommended for lighter on-road cars.
    Is your buddy running the stock gearing?

    Have you run it on dirt or grass?
    How are the temps? Does it get hot?
    What is your gearing?

    stock gearing,have run it through 3 batterys flat out on road/dirt and grass and the temps never went over 40 degrees celsius,my batterys got hot but im puttin that down to nicds not being able to supply enough current quick enough for the brushless,

    heres a onboard clip with a 1800 venom nicd

    Thanks a lot.
    How would you compare torque and speed versus stock Titan 12T?

    The kid wants an upgrade.
    I rechecked the videos of the 35A ESC, I don't think it makes enough difference. Seems I'll have to go with the 60A ESC.

    I'm still unsure about the KV if to be used with stock gearing.

    So I have the money to upgrade my son's Stampede to brushless, but I don't have the budget for a 2.4GHz radio (not even $80 for the Tower 224).

    I've just upgraded my E-Maxx with an ezRun combo. It is usable but still glitches like crazy from time to time.

    I'm wondering if I should step back and just put good brushed motor in there. But how to increase top speed by at least 50% while maintaining the same amount of torque?

    I would get the 35 amp ezrun and look for a cheap 2.4 radio.

    I agree... going brushed when you planned to go brushless is just a step in the wrong direction. There are ways to make a stock radio work with a brushless setup. Or, you can keep your eyes open for a cheaper 2.4 system on e-bay or something. They do come up from time to time.
    The EZrun systems seem to be really good and have received mostly positive reviews. The 13.5 system I think is a little mild for a truck like this though. Most suggest the 8.5 as being ideal. Keep in mind, with the EZrun systems, the motors with .5 in the number are true 540 size motors. The motors that are a full number (9t, 13t etc) are a 380 rotor inside a finned can made to look like a 540 motor. Which is why they can get away being run with a 35amp ESC. If you go with a true 540 motor like the 8.5... you should go with the 60amp ESC. I would buy one of these in a second if I needed a new brushless setup and if I could find one for under $100. If your up to the $100 limit though, you CAN find traxxas VXL systems on the market place for $120 or $125. I think buying the VXL for only $25 more is WELL worth the extra money... but if you can find the EZrun system for the $85-$90 range including shipping... thats a good deal.
    As far as I know these motors all use a standard output shaft diameter so your pinions will fit just fine and if you run the 8.5 motor you should be fine with a 18-19t pinion with an 86-90 tooth spur. But, as always, get a temp gun and watch your temps for the first few runs to be sure.

    Do a search on this forum and you can find cheap 2.4ghz radio alternatives there was a thread with some good links to some.
