    6S Stock poor initial impressions

    Hi all, first post here in the xmaxx forum

    Just got the 8s version and took mine out for the first run on 6s batts and i cant say i was too impressed. Granted my expectations may have been unrealistic coming from a erevo brushless, but can i ask you vets if any of this is as designed with a stock xmaxx running on two 3s batts.

    1. No wheelies. Either on grass or pavement.
    2. Similarly, i dont feel any sense of power like i do in the youtube vids. the thing gradually accelerates off the line, no ballooning of any tires.
    3. Self righting doesnt work. On any surface. almost as if it doesnt have the inertia to come close to flipping.
    4. Its really slow. I understand its a bigger, heavier truck, but I put these same 3s batts in my erevo and the speed is uncontrollably, indescribably fast. In this truck it moves like a tyco car from the 90s.

    Did anyone remember experiencing this feeling on their first run? Would 4S batts change my mind completely? Or do i just need to manage my expectations?

    Hi mate, congrats for your Monster X-Maxx, probably you stay in "training mode" (50% of the power output) for ESC, in the owners manual is the tip for change to "race mode" (forward and brakes at 100%), or "sport mode" (forward, reverse and brakes at 100%), of course, the power output isn't the same in 6S, 8S is more powerfull.

    The manual, pages 18 and 19.

    thanks man, appreciated. i am indeed in sport mode. i thought that too.

    after writing that i went to check some youtube vids and this one is exactly what i am experiencing at full throttle. to those with 6s, is that the top speed you are experiencing too?

    Well, this is the full speed at 6S, the video shows it, but if you want more speed, took out the 54T spur gear and use the 46T what is included in the stock stuff, for install it, took out the pin system and use manual mesh adjust.

    thanks. and yeah if you (or rain dawg or others) can corroborate their 6s speed with what they see in that video, then guess that sadly answers my question.

    i understand the point of the hobby is to customize gearing and batts to achieve your fav speed, but I guess im little surprised there arnt more threads about the poor stock 6s performance.

    im still browsing the forum but its seems almost universal that people say avoid using the 46 spur that comes in the box, no?

    A lot of users play with the 46T spur, but without the pin system adjust, you must adjust the mesh manually for it, the pin system is not enough good for use with more speed spurs.

    When I first got my 8S version in March, I wasn't impressed either running on 6S or 8S.

    The first thing I got rid of on mine was the center and rear differentials. The truck was just too tame with that center differential and since I like my rear end locked as well, that differential went bye-bye as well.

    That brought the truck to where it could lift the front end a little easier on 8S. I still wasn't impressed though, so the next thing I did was get a Max5.

    Running with the 1200XL stock motor and a Max5 has brought the truck one more step closer to the way I expect an 8S truck to perform. Still though, I am not quite happy just yet.

    The batteries and motor will be my next two critical components that need matched very carefully to get the truck where I need it with my Max5 ESC.

    I'm looking at 120C rate batteries and possibly a 980Kv motor and I think I should have a truck doing what I see in all the youtube videos that glorify the truck as appearing to run that way in supposedly stock form.

    I know better though. Those guys dropped another grand into the truck to get it to perform where it is leaving ruts everywhere it goes.

    With my ProModeler servo, Max5, and various other upgrades at this point, I'm more than half way to where the truck actually poses a threat to my 6S E-Maxx Brushless.

    As of right now though, my 6S E-Maxx Brushless will humiliate my X-Maxx until I get that motor upgrade and batteries that are over a 25C rating.

    As for what others have described as a lack of power isn't what we have experienced in the completely stock form. Like I stated it wheelies on demand no matter the surface (including wet grass) and when we ripped it off land on to water it literally spent most of the water run on the back tires with the front bouncing up and down but we only ran about 100ft at a time being to scared it would stall and sink.

    Without the tsm when we floor it, it fishtails and wheelies until it flips. Depending on the surface ours gps's at 34mph to 37mph and we run 2- 3s 5300 mah 50c batteries.

    I bought an 8S when they were brand new and have always run 6S.

    Install the smallest I am running 21/50 on gearing.

    Mine has always taken off good and balloons the tires.

    There is a training mode. Check the manual and make sure it’s out of that.

    Ours is the 8s version and we've always run on 6s, it still wheelies until you let go of the throttle on any surface 1 1/2 yrs later.
    Check your settings as Juanmacine stated, somethings not right.

    I was running the 46 gear on 6S and it shattered on me when hill climbing.

    I went with a 50 Hot Racing spur and as big a pinion as would comfortably fit, a 21 tooth.

    But mine wheelies some, though the Cush gear limits them and has decent speed.

    If you are a speed nut or like big air save up for some 4S batteries and budget for spares.

    8S is rough on the drive train.

    46T are for speed, 54T is for torque, you choose you want in each case, there are a 50T aftermarket spurs, wich is a medium between the other two.

    I also purchased some 10,500 mah 3S batteries from SMC. No problem with current flow from them.

    Love em. Rarely do I run long enough to shut them down.

    I also ditched the Traxxas electronics this year and went with a Futaba 3PV, and a Max5. Even better and the weird little glitches from the Traxxas electronics are gone.

    Other than that I run a TBone racing bumper and full skid plates including the A-Arms. Put some RPM a-arms on the front as a protective measure and installed their screw sets all around after popping a couple of arm ends off of the pins.

    Other than that I run everything else stock. Never broke a drive shaft or anything in the rear. I broke a steering knuckle this year. RPM don’t make those yet. The stock ones are pretty tough.

    Money well spent.

    That is definitely a lot of gas in the tank partner!

    On that Futaba 3PV - was that just a receiver or radio and receiver?

    How are those RPM arms? They pretty firm to a twist or are they pliable like the stockers?

    The RPM ones are more flexible than stock ones, it can screw, literally.

    That would kind of defeat the purpose of a more stout upgrade then

    If they twist easier, how are they going to retain a pin better?

    The advantage of this RPM A Arms is it don't broke, twist but not broke, I prefer and in fact, purchase a Traxxas heavy duty A Arms in green, it come in different colours.

    RPM makes a pin set for the outer ends of the arms that has a nut on the end.

    You get the flexibility of the RPM arms without popping the pins out.

    I have a video of X-MAXX 6S original version. The only thing I swapped out was the ESC to that of the 8S version. I used 6S batteries and it wheelie on demand without running the 8S batteries. I then used 8S batteries and yes it has much more power.

    That reminds me varunaX - you may want to look in the Traxxas Link App and make sure your "Throttle Sensitivity" is set to 0%.

    The problem is, I don't think the shocks were ever offered in orange unless you bought the whole truck is what I'm getting at.

    Remind me to wring my own neck for that mistake of wanting the orange truck!

    Nope, it was the Limited Edition Orange we bought December 2018 and it's ran like this since new. The video VarunaX posted is super slow compared to what ours runs like, his settings must be off or something.

    It really makes me wonder lately about why these threads are popping up lately (not particularly this site) about models just bought within this past year that are reflecting under-powered assessments.

    If I find out that it has anything remotely to do with the Rx - I can't even begin to describe the fury I will unleash.

    In other words, if I go the Futaba route and I have a drastic performance increase before I even buy my motor, I'm going to begin to question some things about what Traxxas receivers can really control.

    Possibly a change in components or maybe manufacturing site or (my theory is app related).

    It has affected everything grizzly; but more so our hobby, which I believe has taken a pretty good hit like you're pointing out.

    I mean it is nice to go out in the world now and not know if your going to live or die because someone next to you coughed.

    It isn't the usual "I might get run over by a bus or hit by a truck" now it is if someone coughs or sneezes, you don't know if your going to live or die.

    Who's idea of fun was this anyways?

    i bought the orange version with the orange shocks etc. but i notice that my shell is bright neon orange compared to the burnt orange i see in other pics. would that have any relevancy on the model version?

    It is just a monitor color or photo difference, the real color of the body shell is the one you have.

    What batteries are you using? What is the C rating?

    It's my understanding that you just got this truck.

    I know a number of new erevo 2.0 guys have reported very slow cars. And it's found to be a esc issue possibly a bad batch of ecs. Perhaps the xmaxx vxl8s is affected by whatever manufacturing issue is going on as well? But this is first I'm seeing on xmaxx...

    Do make you are not in training mode.

    Since you have a erevo. Perhaps. Take the vxl6s esc from erevo. Put it on the xmaxx. And do a short test run. ( I don't know how this esc and xmaxx motor will play together, as esc may get really hot if running long.). But it will at least let you test out if your vxl8s esc is bad and need to call Traxxas or your lhs for a warranty replacement.

    For me I run at 8s and even on training mode lots of power.

    The Futaba 3PV is their mid level ground radio. Just the tx and rx. I bought the Max5 esc.

    Poor performance sounds like an ESC issue to me. Do you have the Blue Tooth chip in your tx? Maybe it needs an update or reset to factory settings.

    I think this is a very good way, the module is aoutstanding and he App too, with updates, the performance is better.

    I think I got self righting to work once on 6 S.

    Then I started reading on heat about blown diffs and I quit trying.

    Only if you're trying to buy just the shocks or wheel hex nuts. I've never seen the orange shocks or wheel hex nuts offered on the Traxxas site since the Limited Edition Orange came out quite some time ago.

    Of course the Limited Edition Orange that I'm speaking of, is not the neon Orange one that is sold today. I can get everything else in orange such as the arms, steering links, and wheels; but when it comes to the shocks or wheel hex nuts, they are no where to be found as an OEM part offering.

    EDIT:

    Correction, I found that they offer the wheel hex nuts in orange.

    https://traxxas.com/products/parts/7758T

    Figures, they want $12 for four pieces of aluminum that wouldn't turn but 10 cents at a recycling plant.

    Op have you tried using you vlx6s ecs from erevo and see if xmaxx runs better? This I'll test if it is a esc issue.

    I talked about this on post #27 but alit of other chatter so may of missed it.

    I guess I could try. I have a mamba monster in my erevo tho.

    From hearing alot of others using 6s in the 8s ver, I believe what I am experiencing is as designed. I will just either gear up (also why is it impossible to find 50t spurs in stock anywhere?!) or shell out for some 4s Batts to satisfy my need for speed

    It wouldn't matter what esc it is as long as different with same batteries. If did a quick swap of esc and just see how it runs. As it's 1 variables to cross off the list... As for vxl6s ecs been reports of bad esc... So perhaps it is also in the vxl8s as well? It's a process of elimination really.

    Something I also may have failed to realize is that the stock gearing is likely designed for 8s Batts since the truck is advertised and designed for 8s, correct?

    In theory I should be able to gear up pretty high (24/46?) on 3s with no issues since the voltage is lower on 6s? Or am I mistaken
