    EZrun 80a or 150a combo

    Xmas is coming up and i was thinking of asking my parents for a Ezrun combo. I like the look of the 80a combo because its cheap and fast but i also like the 150a combo because its really fast and is still cheaper than a Mamba Monster but delivers similar power. Please help me out, i want the 150 but is it worth it or is it worth getting the 80a combo.

    The 80A combo will limit you to 4S. Performance wise, it is similar to the MMM on 4S.
    The 150A combo let's you go up to 6S. Again performance is probably similar to the MMM.

    The E-Maxx takes 4S like a breeze, but 6S puts a lot of strain on it. Be ready for more breakage and upgrade. Now you can always have the 150A combo and run it on 4S. That gives you the flexibility to go up the ladder when money allows.

    Definately get the EZrun similar performance to the MMM system and get the 150A Combo with either the 2350Kv motor or the 2000Kv motor and definately be ready to change some drive shafts.

    Actually dont worry about them till you go to 5s or 6s lipos cause I have been abusing my maxx for about 5 months with the EZrun on 4s and I have had no differential problems. Just keep twisting the shafts is my problem!

    For the price, the performance and the fact your EMaxx will be more reliable on long term I would definately go for the 80 A which will allow you great runs.
    The 150 A is for sure more dedicated to the E-Revo

    I thought all 3905's came with the same upgraded diffs that e-revo has. Gear set #5382X and ring gear/diff pinion gear #5379X

    the emaxx apparenty pretty strong according to taxxas, because they put an mmm in the EMBE and it is pretty much the same as the stock 3905 so i supose you wouldnt blow your diffs right away it will probablly take some time.

    Every company on earth praises their own products saying they are super strong and amazing quality and value for money and blah blah blah.......self praise is no recommendation.

    Despite that, just what everybody else has said, the Emaxx 3905 can easily handle 4S. I've been runing 4S for a while now on the Ezrun 80A and I haven't broken anything. It is bone stock, and using me as an example, I'd have to say Traxxas is right in that it is "pretty strong".

    I'm not saying Traxxas is wrong in making their claim, but just because XYZ company claim that about their product doesn't make it 100% categorically gospel.

    On 4S, they will give you the same performance.
    The only benefit of the 150A is that it can take 6S.

    The 2350kV spins faster than the 2000kV but has less torque.

    2000kV is the right choice for a heavy truck like the E-Maxx I think (that's what I have).

    No idea, but plenty fast for bashing. Significantly faster than stock.
    Since stock is given for 35mph by Traxxas, I'd say at least 40mph.

    I would not recommend using NiMH on the ezRun. Lipo is the way to go. Get the new ******* hard case 5000mAh for less than $20 a piece. They fit perfectly in the E-Maxx tray. 4 of them will give you a solid hour of bashing, and on stock gearing, the batts, ESC and motor will just get barely warm.

    How did you fit the 2000Kv motor? I just got one and the motor hits the trans and only get like half of the adjustment for setting pinion to spur?
    What gearing you run?

    Thanks

    Ooooppppss, my mistake. I mixed things up. I have the 2350kV motor.
    And with stock gearing, it works like a charm on the E-Maxx. Nothing gets past barely warm when bashing.

    Like in the other thread the single motor mount from traxxas will give you more room plus it will help balance the weight in the truck.

    I have 80a in a 3906 and it is awesome. Unless you are trying to break some speed records, I can't see the point of the 150a. If you are a basher, 80a and some 20-30c lipos will be more than enough, speaking from experience. So far with the 80a I have smokes a rear diff and a spur... Lots O Power...
    If you can't be with the one you love, love the one your with!!!

    good what do you think should i buy the Ezrun 80 combo with the 2000kv or 2350kv motor. Im more of a speed demon than a basher but i dont mind the odd bash on grass,gravel,dirt and jumps.

    Are you guys running 2- 4s lipos with the 80A EZRUN ? What kind of battery straps are you using?

    They're not running two 4s packs, they're running 4s in total - most likely two packs of 2s lipos. The stock battery bars should work in most cases unless you're getting way up into the 6000+ mah range, but it depends on the exact battery pack being used.

    If you use hardcase lipos (***** or ******* are cheap), they have the same size as a 6-cell NiMH pack, so you just use the standard battery hold downs.

    Goodluck getting ANY ezrun's from now on.

    I have found out from the horses mouth that the EZrun 80/150 are no longer. They are being replaced with
    CLICK ME

    This is why nobody has them in stock and they aren't getting more stock. I have been told by HW themselves that these new XEruns will be being shipped out very soon. I presume they will have an 80 and 150A version.

    So, to anybody looking for an ezrun, good luck. If you can hold off, I would if I were you, this new one should be better with any luck.

    In case the photo link doesn't work in my last post, here it is at photobucket


    Yeah, with any luck it'll be the same or even cheaper than the ezrun series. I quite like the look of the new ones and I'm hoping they are even better than ezrun.

    It's only for 2-3S, and it's "stopped manufacturing"

    3S on a 2200-2350kv motor would be slow in an emaxx.

    Are you serious? Forget THOSE xeruns. They may carry the xerun name, but they are not for a MT. They are for smaller 1/10 scale vehicles and they all take a maximum of 3S lipo. MT really require 4S lipo.

    Buy from this shop, http://ecpower.com.hk/index.php?main...roducts_id=274
    According to them, they still have both the 80 and 150A ezruns in stock.

    Couldn't really wait to figure out what HW was doing there with the ezrun, but now kinda wishing I may have waited to get this XErun setup.

    Did you read any of the links about the xerun? None of them are good for running more than on pack of 7 cell or one pack of 3s Lipo. I wouldn’t go near them without more information.

    That is on 1/10 scale setups not the 1/8, i'm sure the 150A exrun will be good for 6s. Usually when you come out with a new version you improve on previous versions.

    One picture on an image upload site is a long way from having a system that will handle an Emaxx. Have you got anything else or is this wishful thinking on your part?
