Managed to drain about 50 battery packs and no major problems, replaced front lower arms to Metsafil, oil in shocks to 500 ( front) and 1000 ( rear). Quantum+ springs (9 coils), M5 washers. Lovely little car! Have a great weekend! Where in London are you? Where do you normally go to bash around? Quote Link to comment Share on other sites More sharing options...
BaldyMan Posted August 19, 2021 Share Posted August 19, 2021 I've been enjoying my Quantum+ Flux. It is brutally quick for what I paid for it and I've had no real trouble with it besides having to replace the front arm that is notorious for breaking. My issue is I'm not sure exactly where these things are best suited. I've taken it on gravel paths and it gets battered with loose gravel, you can here it getting into all the running gear so I'm avoiding loose gravel. Same issue with anything other than short dry grass, it gets everywhere. It'd need new tyres for road use so there's not really much point in that. I'm guessing it is best suited for dry hard pack dirt with no loose stones which I tend not to be able to find. 1 Quote Link to comment Share on other sites More sharing options...
Hell horn. Posted August 19, 2021 Share Posted August 19, 2021 That's about it. Dry hard pack.i just send my one off anything I can find and over anything I can find. Fix it up after. And go again. 2 Quote Link to comment Share on other sites More sharing options...
SteveohhSteve Posted August 22, 2021 Share Posted August 22, 2021 I've now lost all drive to my rear wheels. Front are fine but rear axles don't turn at all under throttle. Quote Link to comment Share on other sites More sharing options...

Seminole81 Posted September 13, 2021 Share Posted September 13, 2021 *tumbleweeds* I see Maverick are bringing out a few new trucks. I actually really like the look of the 4S one, but I think it will disintegrate on the first big crash... Quote Link to comment Share on other sites More sharing options...
BaldyMan Posted September 26, 2021 Share Posted September 26, 2021 I've mixed feelings about these cars. I have the Quantum Flux + in blue/grey running on 3S and it's an absolute blast. My daughter has the pink brushed MT and so far I've replaced motor, servo, couple of suspension arms and now the diff has packed up. Awful grinding sounds and loss of power to the front wheels. I've got a feeling I might be better off stripping it for parts and keeping them for my Flux + and then picking up a cheap 2WD Tamiya buggy to put all the motor and electronics into. I think my daughter is a bit intimidated by it's size and since it has broken a few times she has lost confidence in driving it. Its like every time she takes it out a part breaks and it ends play. With a 2WD buggy I'm hoping the lighter weight and simpler drive will make it more enjoyable Quote Link to comment Share on other sites More sharing options...

I do fancy a Tamiya kit to build up. Something like a Grasshopper or a Rising Fighter. I know it's a downgrade but it's more of something that she can be a part of building and won't be so intimidated by. I've looked at Rustlers and Bandits for a good 2WD option for her as well. It's mainly about cost and trying to recoup some of the money that was sunk into the Quantum MT 1 Quote Link to comment Share on other sites More sharing options...

Was the dif making any grindy crunchy sounds prior to it happening ? No grinding noise, just the sound of the big cog spinning but not making contact. Anyway, I've taken it all apart, I think the small cog that connects directly to the diff came loose. Took everything apart, put it all back together again - seems to be ok. Haven't tested it properly as I'm still to put all the chassis back together. Quote Link to comment Share on other sites More sharing options...
BaldyMan Posted October 7, 2021 Share Posted October 7, 2021 Has anyone got any recommendations for street tyres or wheel and tyre combos? The Quantum + Flux has 14mm hex fittings which means there aren't a lot of options it seems and I'm struggling to find any adapters. I'm not keen on completely changing the 14mm to 17mm as then just changing street to offroad wheels becomes a massive chore. Quote Link to comment Share on other sites More sharing options...

I've seen these and was unsure about them. Are these absolutely fine and won't come loose? If this is the case then I'll just go out and get some and some wheels. Do people bond the adapter to the wheel or just put them in and screw it tight? https://www.modelsport.co.uk/product/fastrax-1-8-truggy-eagle-mtd-on-5spoke-black-0-offset-pr--421232 I've had my eye on a set of these for street blasting Edited October 7, 2021 by BaldyMan Quote Link to comment Share on other sites More sharing options...

I’ve not used these but looking at them there’s nothing to come loose once the wheel is tightened 👍 Quote Link to comment Share on other sites More sharing options...

Once that's done and the wife has forgotten how much I've spent I'll get the wheels and adapters ordered in 1 Quote Link to comment Share on other sites More sharing options...
BaldyMan Posted October 9, 2021 Share Posted October 9, 2021 Well the old pink Quantum in now a little Rising Fighter. The large ESC meant I couldn't install the driver but my daughter thinks they're naff anyway. I was tempted to try and get the pinion gear off the 550 from the Quantum but the stock 540 is plenty for her. Any more and the car will become far too skittish. It's already quite twitchy as it is. 2 Quote Link to comment Share on other sites More sharing options...

I may end up going down a similar route with my flux 80+, run it till its a bit sorry for itself then use motor and esc in a speed runner 1/10 car Quote Link to comment Share on other sites More sharing options...

I love the truggy but it is massive compared to a 1/10 buggy and I always look at buggies and get buyers remorse. I think I'll eventually try to sell it on and get a Typhon or that Corally Radix that gets rave reviews. Buggies are just easier to toss in a backpack and take anywhere.

Then I'll look at something else.

paul125 Posted October 30, 2021 Share Posted October 30, 2021 Hi All. I have a Quantum flux XT. Its running great but when I ran it the other day I had something strange. I was running it on a tarmac carpark and one section of the tarmac was wet. When I tried to accelerate full on the wet section, my XT just started spinning in circles on the spot. It makes me wonder if all the power was going to one of the front wheels. I know the flux xt doesnt have a centre diff only front and rear so potentially all my power is going forwards?? It doesnt wheely much either on a 2S 50C battery pack. Any ideas or advice for me? I was hoping that as it was 4WD, it should be able to cope with a bit of wet tarmac. Thanks Paul Quote Link to comment Share on other sites More sharing options...
bertberr Posted October 30, 2021 Share Posted October 30, 2021 Wet tarmac and a light truck with a BL motor, may as well be sheet ice. The weight going through each tiny contact patch on an RC car is proportionately much less than a real 1:1 4WD car, exacerbated further when you throw in compound, pressures etc. And if its doing donuts then the power isn't going to the front, its mostly going to the rear wheels. I wouldn't worry personally, if it was doing same thing in the dry, then I'd be looking at why, but in wet, well that's what I'd expect, particularly with stock hard plastic tyres 🤪 1 Quote Link to comment Share on other sites More sharing options...

Is a tyre upgrade normally worth it? More grip would be good. Any recommendations? Quote Link to comment Share on other sites More sharing options...

XT handles like rubbish compared to the MT on the field, and that's down to the tyre treads. Quote Link to comment Share on other sites More sharing options...
Kyo Posted November 26, 2021 Share Posted November 26, 2021 Hi, Does anyone know the size of the centre shaft drive cup grub screw for the Flux XT? Managed to strip one and had to butcher it to get it out, the cup is OK but not sure what size grub to buy (the parts diagram doesn't help!)
