If you want a kit then try a Tekno MT410
I bought my son a maverick quantum but it was returned after a short period of ownership due to poor quality. He now has my Team Associated Rival MT10 which is a beast.
Thanks, looks good but a bit pricey. I've had Tamiya before and I do appreciate quality so maybe Schumacher is the way to go..I bought my son a maverick quantum but it was returned after a short period of ownership due to poor quality. He now has my Team Associated Rival MT10 which is a beast.
TRX4m for me is going to have to wait (probably for good long while).
The ESC in my Infraction died while out bashing the other day, but the motor is still good. And I'd been planning on upgrading the ESC in the XRT too (just the ESC). But per the other thread, I wound up ordering 2x Max6 1100kV combos.
Original plan was to just swap the ESCs and deal with the motors later. That didn't last long, I've just ordered motor mounts for both vehicles to take the bigger cans. I went with a US made PPS mount for the Infraction, and an MMM mount from Germany for the XRT.
And, of course, the motors have 8mm shafts, so I've just ordered a bunch of 8mm bore pinions too.

Further to this, we had endless problems with the Maverick quantum, firstly the brushed motor lunched itself after its first run, we took it back and had a 2/3s brushless system installed, this met a smoky demise after 3 runs on 2s, plus other small issues like losing dog bones on the front axle, using metal sealed bearing instead of rubber which rusts in the sight of water. 
The shop took it back without question and I walked out with this instead.
Arrma Vorteks 3s
The shop also threw in a Dusty Motors cover for free which was nice of them
It’s rapid and handles really well. Although I am having a few teething issues with low voltage cutout on the esc. Something which I am not suffering with on the MT10. I believe I need to get a spektrum program card and update the firmware. Also have a 15t pinion to try, apparently you get a bit more run time with it?!
But from a maintenance perspective it seems really easy to work on.
Had some necessary upgrades delivered for both of them too.

Check the manual. I don't think you need a programming card to adjust the parameters. You should be able to do it using a beep-code / LED flash menu on the ESC itself.
EDIT:
Looks like the LVC setting is just LiPo vs. NiMh. I don't think you can do anything about this. If you're using LiPo, leave it on LiPo setting. NiMh setting will be too low and you could end up damaging your battery.

Afaik the program card once you update the firmware it allows the voltage to go lower as it’s set at 3.8v per cell normally. The card is on the way so will have a play about with it when it arrives. EDIT:

Sorry I’m still new to electric rc, what do you mean by run aggressive LVC? Protects the battery, you musn't discharge a LiPo too much. Or fire

Like I say it’s a big learning curve all of this, not even sure I’m asking the right questions

What batteries do you use? Mine are 3s 5200mah 50c and the esc is the Spektrum 100. I get a relatively short run time and performance cuts out quite short into the runs. Just trying all sorts to get more out of the batteries. As my MT10 lasts for ages on similar batteries.
Like I say it’s a big learning curve all of this, not even sure I’m asking the right questions
I use 7.2v and 8.4v NiMh. I can't be doing with precious Lipos and their moods Like I say it’s a big learning curve all of this, not even sure I’m asking the right questions
but to be honest, my rere Bigwig with an 8.4v NiMh and a Sport Tuned motor is as quicker as my friends, running a 2s. So I'm quite happy.I would say you have an issue there though. 5200mah 3s's should be lasting you a good while, up to an hour really, depending on use. Sounds like you might need to look at your ESC. Also, gearing can make quite a big difference, too overgeared can sap performance. I prefer lower gearing anyway, makes it rip from a standing start, and gives better rooster tails!
And mate, don't worry about asking questions, keep asking away. That's what this forum is for! And most RC enthusiasts will spend as long as it takes to help someone new enjoy the hobby!

ked... but beyond that they can be recovered with a very low trickle charge in nimh mode up to the point that your charger will accept it as a lipo... during this process it will warm up a bit - warm ok - hot is not.. if the voltage is not increasing slowly... stop trying!Lipos perform their best at 42C - charging and discharging....
I was trying to remember how long I have been using lithium polymer cells and I think its around 18yrs.. in fast electric boats, And back then they were to be feared and a proper understanding of how they worked was required..
In all of this time I have never had a lipo fire whilst charging,discharging or whilst in storage....
Imo modern lipos are pretty safe.... get a decent balance charger and understand the information it can give you regarding individual cell voltages and internal resistance and you won't have any problems.
Buy your batteries from established manufacturers, I avoid amazon and ebay.... CNHL have been performing very well for me recently and their sales and offers are good!
P.s - I would expect 15m from that battery in an arrma 3s... and the spektrum 100A esc is rebranded hobbywing.... their esc programming box works fine

My Hobbywing program card (the cheapo 7-segment job) doesn't work on Spektrum ESCs. Does the multifunction LCD Hobbywing work on Spektrum? The first of my Max6 combos arrived. The 5687 1100kV is a big boi! Waiting on motor mounts. And those 8mm bore pinions are
Got some bullets and what not coming before I can put it all together. Will be gearing that Infraction up a touch, be rude not to, going from a 2050kV to an 1100kV

Mostly likely to be something other than battery causing it. All else being equal 2S LiPo will easily out perform 8.4v NiMH. Remember 2S LiPo you charge to 4.2v per cell, so 8.4v resting voltage. The LiPo will have way less voltage sag under load than the NiMH and will support far higher amp draws as a rule. but to be honest, my rere Bigwig with an 8.4v NiMh and a Sport Tuned motor is as quicker as my friends, running a 2s.

Yes, the led one with a blue band works fine on all my spektrum ESCs...Better stock up on tyres for the infraction!!
I can recommend 1'000'000 cst for the centre diff aswell!

This is my charging set up at the moment. It’s not the neatest and I need to extend some cables but it works ok as it is.

I have one of those, and I'm sure I tried it on my Spektrum and it didn't work. I'll give it another go.
Got some tyres, but yeah, going to have to get a few more sets for sure!
Regarding centre diff, does the handbrake still work ok with 1,000,000 cst? Not too stiff?
That ESC programming card worked on both my 3s arrmas and the infraction with no bother... their all a couple of years old though so maybe they have changed the software to block it? - dunno.
Regarding the runtime on the 3s - i fitted a dusty motors cover to my 3s typhon and it created a heat build up which caused my esc to thermal as it couldn't pull enough cool air in.... have you tried running the vorteks without it?
