Jens Posted August 10, 2020 Share Posted August 10, 2020 Does anybody know a solution for the hardened plastic diff hubs? My boy already spoiled 2 (axle drive shaft is spinning through) . Luckily I bought 2 before and I am going to fix this one for the time being. But is there any other, better solution? Quote Link to comment Share on other sites More sharing options...
tiaalto Posted September 25, 2020 Share Posted September 25, 2020 Hello, an another old geezer looking for a RC car after some 30-odd years break from the hobby. I'm being drawn towards the rock racer looks and the Mauler seems to be a strong contender. I'm not looking towards serious crawling, more like a sprightly ride in rock and root infested woods. Not looking at basher speeds, more like 12-15 mph max with good acceleration with NiMH or 2s LiPos max. However judging from the tons of forum pages and vids I've gone through the Mauler seems a bit slow for my taste out of the box. It seems the Mauler can accept different pinion sizes unlike the Outlaw but I haven't found any mention how big can it take and whether a mere pinion change would give me the performance I want. Can anyone shed some light on this? Probably a motor swap would be fine too but I'd rather not start replacing the whole electronics set from the get go.

tiaalto Posted October 7, 2020 Share Posted October 7, 2020 Actually I just went ahead and ordered two (because kids) RGT Rock Hammers which is basically the same truck as the Mauler. While I was at it I also got two of these servos as upgrades: https://www.banggood.com/DSSERVO-DS3225-25KG-180-Degree-Metal-Gear-High-Torque-Waterproof-Digital-Servo-For-RC-Airplane-Robot-Car-p-1353688.html?rmmds=myorder&cur_warehouse=UK Now I wonder if I can just get away plugging the servo in to the 2in1 receiver/ESC (apparently the RH comes with the same electronics as the Mauler these days) or do I really need to get a BEC? Not that wiring up a BEC is actual rocket science but I'd prefer not to deal with the hassle of soldering if I can help it. Quote Link to comment Share on other sites More sharing options...
mugen mad Posted December 26, 2020 Share Posted December 26, 2020 Anyone know if you can fit a wraith gearbox or another gearbox in the mauler and also what prop shafts are people running in these only just got one and been out the game for nearly 5 years Quote Link to comment Share on other sites More sharing options...

This is a year later now but same thing happened to mine. Saw that the FTX aluminium replacements were £28 a pop and found some on Amazon that worked for £10 each. Unfortunately the following day the screw stripped out of the front left hub carrier and again the FTX aluminium replacement is around £40 which is crazy so I have spent most of the day looking at Wraith axle sets to replace the entire thing with but lead times are pretty crazy.

I'm also looking for a solution to this as the rear diff block stripped on the first day . All the ftx aluminium ones seam to be sold out.

alexbver Posted December 28, 2021 Share Posted December 28, 2021 was wondering if these would fit the mauler https://www.injora.com/products/metal-front-rear-portal-axle-with-protector-for-axial-scx10-scx10-ii-jeep-cherokee?variant=39681552941104 I see they are a little shorter than stock anybody tried them Thanks Quote Link to comment Share on other sites More sharing options...
wombat Posted December 28, 2021 Share Posted December 28, 2021 Hi, I had this problem with my Mauler, sorted thanks to help from other forum members. The diff unit is the same in a Maverick scout and some Hsp models. I ordered a full metal diff assembly for a HSP94180 off ebay for £5.99 which took 3 weeks to come from China. Also check out Aliexpress.Hve not fitted it yet but looks like good quality Hope this helps Quote Link to comment Share on other sites More sharing options...

All the ftx aluminium ones seam to be sold out. Yea as others have said HSP 94180 or RGT 18000 (Rock Hammer) based parts are the same for the axles/diff. The metal diffs seem pretty sturdy, unfortunately with the new axles on order they were a total waste of money for me since the new axles use different diffs. If only the screw had stripped out 1st. Oh well I have a wood screw holding it together for now until the axles arrive in a couple of weeks. Quote Link to comment Share on other sites More sharing options...
Trunkle Posted December 31, 2021 Share Posted December 31, 2021 Mine arrived through the door yesterday, first big crawler for me. Was planning on modifying it but will most likely just run it as is maybe some new tires/wheels. I've noticed a lack of modifications available for it though, does anyone have a link or two they can share? I'm slightly paranoid about plastic gears and will replace these and the servo at the first opportunity. Quote Link to comment Share on other sites More sharing options...
wombat Posted January 1, 2022 Share Posted January 1, 2022 Hi @Trunkle, welcome to the Mauler owners club 👍, never regretted getting mine, for upgrades look on ebay and aliexpresss. I would start with the metal diffs then see what you fancy / need next Cheers, Ian 1 Quote Link to comment Share on other sites More sharing options...
Russell iow Posted January 3, 2022 Share Posted January 3, 2022 (edited) what replacement axles are recommended? Something else broke today so i think new axles would be best. Im guessing portals would not be as durable as standard type? I need to build it strong enough to survive a three year old.

Shergar Posted January 3, 2022 Share Posted January 3, 2022 The plastic casing or the metal driveshaft that goes into the diff/crownwheel? I’ve proper abused mine and they have been no bother really, might be bad luck? Slower motor or lower gear pinion is also an option for a 3 year old? 1 Quote Link to comment Share on other sites More sharing options...
Russell iow Posted January 4, 2022 Share Posted January 4, 2022 It's the end of the plastic axel casing that holds the pivot for the hub to the axle, on the front. Quote Link to comment Share on other sites More sharing options...

You can get replacement axle housings pretty cheap from modelsport. Won't be any stronger but you'll at least get back out for not much outlay https://www.modelsport.co.uk/product/ftx-mauler-4x4-rock-crawler-rtr-yellow-420978/spares-1682 2 Quote Link to comment Share on other sites More sharing options...
timorous Posted January 19, 2022 Share Posted January 19, 2022 Am I just really unlucky or is this typical RC ownership? 1) diffs strip making it effectively 1 wheel drive, replace with alu diffs and all good for 1 day then. 2) screws strip on front axle steering hub so car wont steer. Replace both axles with metal wraith ones. All good for 2 days then. 3) Steering servo pin bends a fraction jamming up the servo. Replace that with a 25kg one. Good for 2 hours then. 4) 2 in 1 esc/rx does something and now car only goes backwards. Checked transmitter and it is not batteries or a fault there.

wombat Posted January 20, 2022 Share Posted January 20, 2022 if you reverse the throttle settings on the transmitter does the car then only go forwards. If so would suspect a transmitter fault Quote Link to comment Share on other sites More sharing options...

wombat Posted January 20, 2022 Share Posted January 20, 2022 Does sound like the esc then. When I bought my mauler the esc/receiver had already been changed for separate traxxas items, along with the transmitter Quote Link to comment Share on other sites More sharing options...
Russell iow Posted January 21, 2022 Share Posted January 21, 2022 (edited) Ha sounds about right, so far I have superglued the front upper suspension arm (both ends), front hub carrier and rear diff block . I also replaced the striped spur/ pinion and fited a hobbywing 1080 esc so i could run 3s batteries (esc set to 50%).

Do you mean you have successfuly repaired the rounded off diff block ? I have metal ones in mine now but would be handy to repair the old units just in case Cheers, ian Quote Link to comment Share on other sites More sharing options...
Russell iow Posted January 22, 2022 Share Posted January 22, 2022 yes but its a bodge. I just superglued the drive shaft in there and its holding. Quote Link to comment Share on other sites More sharing options...
