    Same here. I ordered a HW Max5 last night after reading about the VXL-8S issues that have popped up. I'm just going to piece together the "upgrade kit". I looked up the current version of the parts included in the kit and assuming the new model's parts are roughly the same price you should be able to get all of the parts for fairly cheap. The unknown part is the center diff but I don't imagine that will be more than $50. I figured even if I spend $150 in parts, my esc was still only $200 and I know it will handle the power without issue. I can also try to sell the VXL-6S to offset the cost some.

    2 reported cases of people having an issue with the new VXL-8 is hardly a reason to get all excited not to use the new ESC. Traxxas has probably shipped out thousands of these kits by now, and I'm sure they are well aware there will be a small percentage, as with any manufactured electronic device, will have some defects. Its what the manufacture does after the problems arise that should be of more concern. And in both cases I have read Traxxas has asked for the ESC's back and will be sending out replacements. IMO, sounds like is Traxxas standing behind it products.

    Capflya may do what he pleases with his money. If he feels the new 8S ESC may succumb to a similar situation as the outgoing 6S, that's all the reason he may need. I definitely agree with you that Traxxas is doing what they can to fix any current and future issues.

    As for me, I'm still quite interested in the upcoming 8S model, but am going to continue to lurk the forums and wait until some reviews come out before putting the money towards the new model Exciting times for RC! Still waiting for Traxxas to "at least" let us know when they're going to reveal their next model. Let us know the fiscal quarter! Haha

    Man you guys are hating on the esc already, give it a chance. I think the next X will be a awesome truck. Untill then I will keep beating on my stock vxl6.

    There's no doubt about Traxxas' customer service is next to no one, but I have had everything what the update kit offers and much more for over a year now. I can run 8s if I want to, but prefer to run 6s. I have wheelie wheels, non ballooning tires, I have body savers, I can put in any battery I want to use, and I have telemetry RPM's...and the list goes on.

    I'm sure the new Xmaxx ESC will be fine, but I don't need one having the Leopard/Castle/Kershaw set up, so why shouldn't I wait a little while to make sure that the two forum reported ESC failure cases don't multiply down the road. Anyway, I'm not a Traxxas haten kind of guy. I'm more like a Traxxas helper king of a guy...anyway, I try to be.

    Nick, that looks like a nice sport bike you got there. I'm a 1098 man, and a avid twisty lover. From your picture, though, I can't make out what make/model you have. Also, Killroy, Wonder Dog was the greatest canine super hero's ever to live on Saturday morning TV. They took him off the air, because the PC crowd (even back then) didn't like the idea that he had to take a pill in order for him to get his super powers...sad.

    I think its good that Traxxas upgrade the Xmaxx but why do they want our old (bad) ESC? it really should be 300$ and we keep the old ESC.

    personally I am done with Traxxas ESC's, Xmaxx ESC issues and the VXL-3s ESC = no thanks, ill get something more configurable with better trackrecord and reputation. With that said I think its great if Traxxas continue to improve the xmaax, hopefully every year.

    better tires please, 6s on tarmac with high gearing is expensive, i cant imagine 8s.

    While I can't speak for the 8S ESC I can say the drive train upgrades are holding their own so far running which is what I was after. I don't beat the bag out of it or jump garages but there's no wear on the drive cups which is a good start!

    Where in my post did I say anything to Capflya about not buying, or spending his own money on a HW Max5? I was simply saying as of this moment there are only 2 esc failures (Gio, and Gorson) that I know of. Its not time to panic yet. Once the 8s comes out and more people purchase the trucks, it may change. But for right now it probably a 1-2% failure rate, which is extremely low for a new ESC. How many HW ESc's fail? Who knows, I'm sure if I dig around there are reported failures on those as well.

    Sorry, not trying to hate on traxxas. I'm a die hard traxxas fan, I still have my kit built rustler that is ~20yrs old
    I just feel the VXL-6S was a dud and there have been very few reports of the 8S in general from what I've read. I thought I read about 4 people who had issues but maybe I miscounted. I was ready to have my LHS order me the power up but decided to hold off for now since these have popped up. I'm sure traxxas will figure it out and make it right.

    Cause they know the old one can catch fire.so why would they want people to keep using them.this way there giving a better and safer esc for the old one and there paying u back for it.i don't like a lot of things traxxas does but I think this is a great move on them.

    I sure hope they have fixed the "fire issue" with the official recall that is the fuse wire and the firmware upgrade, No this is not a act of goodwill, the true price of the power up kit is 300$ + core cost.

    They want to get rid of the VXL-6s and they are soon not gonna sell it as a spare part because its a dud.

    250$ from Traxxas that is very expensive for VXL-6s almost like they dont want you to buy it.

    This is better 153$ from a ok online retailer here https://www.amainhobbies.com/traxxas...ra3365/p476552
    in stock as I write this.

    Personally in my opinion, 250$ for VXL-6s I consider that to be very poor value for youre money, even at 153$ its not good value compared to other products.

    Edit: The more I think about this, they may be the first to test out this innovative marketing scheme.

    My guess is that Traxxas overprice so no one will buy it and as soon as the 8s version is released they dont sell the VXL-6s anymore. As for the online retailers they probably dump the price on it to get rid of their existing stock before this ESC become useless.

    EDIT: Anyone that have followed the Xmaax recall history would never buy the VXL-6s ESC for 250$ or 153$. I will use my Xmaax VXL-6s after it is firmware upgraded with 4s on another RC.

    Your right. They do that to support their dealers. If they didn't, there wouldn't be any, because you/I would buy everything from them directly due to it being cheaper. Also consider, that you don't pay shipping when ordering Traxxas stuff though the dealer, because a dealer gets free shipping with certain size orders. And, if your ordering from a LHS in a state without sales tax, that makes ordering from a them even sweeter.

    I've had my kit for about a month now, and have not had any issues. its a big difference just running it 6s, but running it 8s is even better. Although getting those big batteries out is a pain. I used everything except the fan. I preferred my Castle fans instead. If you dont want to pay the deposit fee and wait for a refund, you can call traxxas and they will give you an RMA to return your current ESC. I sent mine back and received my kit in about a week.( I did expedite shipping to them to send my ESC). your existing batteries will work on the new charger. The only thing I dont like is, You need to push the link button on the charger to connect it your phone every time you want to connect it to your app. And the app read out is not accurate. It will say 10 mins left and show current charge about 60 to 70% then a minute or 2 later its done.

    Upgrade kit is great so far. Running 6s 8000mah 40c on the 18/54 gearing. Have about 7 packs through it in mid 70's FL weather.

    Ran it hard at a construction site, no problems at all. Got about 40 minute run time, no heat issues. I don't even see myself bothering with 8s.

    So far ESC is fantastic, seems really smooth as well. It's easy to just crawl along with it.

    Center diff is great and no slipper to worry about is nice.

    I did the HR alloy diff cups and HR diff covers while I was at it. Everything feels super durable. Very happy with the power up kit.

    Just picked up an 8s kit from my LHS here in Canada. Funny they had no clue about the core charge.

    $440 CAD before taxes and I get to keep my Old esc too wonder if I could get some money back by sending my esc back. looking forward to better weather soon!

    Actually for $440 CAD it's not bad compared to $475 USD. It's only $299 USD if you return the old esc. I'd rather keep mine if anything goes wrong with the new one.

    I'm from Toronto, got it from "big boys with cool toys". Give them a call they might be able to ship it out to you.

    This upgrade kit versus buying the new version, if you just look at the new stuff and price on every part you get with the new version like the new motor which the upgrade kit does not contain and so on it just starts to feel better to buy the new version directly?

    But, you also have to factor in what a person will lose when they sell their V1 Xmaxx. I'm sure they won't get out of it what they paid for it.

    On another note; I wonder why Traxxas' power up kit don't include that (plastic rear body protection piece) you see on the new V2 Xmaxx's?

    (I already run it with 6s and 8s but this is intresting)

    Well you also need 2 new 4s batteries and maybe chargers, add that to upgrade cost unless you already have it.
    Personally i think its pointless to buy the powerupkit if you dont use 4s batteries because that is the entire point with it.

    Traxxas 4s battery and charger kit is not cheap and only 1 charger, no way, i dont have time for that on a RC that requires 2 batteries, i need to charge both batteries at the same time and would need to buy one more traxxas charger.

    It will be intresting to see part difference between on these mixes

    old xmaxx
    powerup kit old xmaxx
    new xmaxx

    You can probably upgrade every part that breaks on a old xmaxx with a new xmaxx part or parts if needed.

    Why buy traxxas batteries and Traxxas charger? Plenty of powerful reasonably priced dual chargers out there.

    I also disagree that the point is to run 8s. I'm running the power up kit and the new ESC on 6s geared 18/54 with reliability. The point of the power up kit is just that reliability.

    I honestly don't even see the need for 8s, it's very fast geared 18/54 on 6s. If I want to do 50+ mph I have other RC's that are much more suited for that. I'm hitting a construction site today and the extra speed on 8s would be unusable.

    https://traxxas.com/products/parts/8s-power-up

    It's not the reliability kit.

    And you do realize that 6s is supported of the box in current model.

    I was at a LHS yesterday.They had one. Im waiting until next month for the 8s version. Im only going to run 6s, 8s seems a bit much. Thats just asking for breakages. I learned years ago running FE boats, always get more speed controller than you need. Running things at the max it will handle, well, be prepared for repairs and something to get cooked.

    Logic is not your strong suit. The old ESC was catching fire and having thermal shutdown issues on 6s, the ring and pinions were breaking, the slipper was melting, the dog bone pins were snapping, it lacked a center diff which allows the vehicle to off load front to back thus taking strain off the drive-train. Everything in that box is clearly aimed at correcting all of the issues related to the V1 X Maxx reliability and durability issues. The power up kit is most certainly aimed at making the X Maxx more reliable with the option to run 8s.

    Ever hear of this thing called marketing? Power up sounds cool. I don't think it would be a good marketing strategy to call the kit "this fixes all the stuff that was breaking and bursting into flames kit"

    Feel free to be stuck on the name though.

    Right on man, that's what I'm doing. Smart move, 6s with this setup and you will have a fun, powerful, fast and reliable vehicle. I've been in the hobby since the 90's and you are correct, more ESC than you need is a wise choice.

The power up kit is most certainly aimed at making the X Maxx more reliable with the option to run 8s.

    Ever hear of this thing called marketing? Power up sounds cool. I don't think it would be a good marketing strategy to call the kit "this fixes all the stuff that was breaking and bursting into flames kit"

    Feel free to be stuck on the name though.

    With regards to 8s vs 6s... etectrically speaking 8s will be better. The higher voltage reduces heat. Ive got to work on some large DC electric syncronous motors and they are 4000v plus. DC is effected more by resistance in wires and cause heat plus the higher the voltage the lower the current.

    I have a few Emaxx trucks with RX8 and other has a MM2 both run smoother on 6s vs 4... I just gear down a little.

    From traxxas engineering the best bet would be to run at 8s but instead if gearing at the motor, re gear in the diffs... that will make the truck more controlable on 8s.

    This makes no sense at all. I currently have 7 RC vehicles and when you run them on their maximum amount of voltage for the respective ESC geared the same it runs hotter period. Saying that more voltage reduced heat goes against the very laws of thermodynamics.

    Smoother also makes no sense at all either, in fact when I run my custom build Rustler at the track I run it on 2s, not 3s because it's far more controllable and the throttle response is tamer. I will run the track much faster and with better control because it's not out of control fast.

    Gear at the diff????? This is not a Ford 9 inch with your choice of 4.10 or 4.56 gearing. You can only gear at the motor on an X Maxx they do not offer different ratio diff gears.

    I think I'm in bizzaro world.

    It does make sence, more voltage means less current at the same power output, current is what causes heat.

    Yes the motor can run hotter with higher voltage because now its turning faster..

    A lot of tool motors such as saws or large electric pump motors use higher voltage to reduce current draw. I switched my bandsaw at home to 240v from 120v the motor runs much cooler when doing longer cuts.., ive also effectively cut my current draw and dont pop 15amp breakers

    This does not translate to RC ESCs at all my man, I don't know what you are talking about as far as power tools. More voltage means the motor will run faster and draw more power through the ESC=more heat FACT. You are confusing things as far as a bigger battery, it's C rating and mah which gives you amps not the voltage.

    The amount of power a battery can deliver is its voltage times its rated current. So a 2s, 3 Ah, 25 C LiPo for example, could deliver 2*3,7 [V]*3 [Ah]*25 [1/h] = 555 W

    Again you are violating the laws of science by saying that putting more power through an ESC will cause less heat. That's impossible.

    Sorry man, but you are incorrect. It's common RC knowledge that as you go up in cells, you need a beefier ESC to handle all that power efficiently. Why do you think the V1 ESC was getting so hot and going into thermal when people were running it on 6s? It couldn't handle the power. More power=more heat period.
