👍 switched mine to 20/50 and couldn't figure out how to adjust it... thank you !!!

[@MyDailyAdventures-andLaughs]

Thanks for the quick n easy walkthrough, bro

[@wyshtechairsoft]

No problem! Glad to help!

[@paulachhammer9945]

Easy to follow. On point. Nice work

[@wyshtechairsoft]

Thanks for the input!

[@alistairclark6814]

It's also useful to check your motor bearing if you are chewing gears. They need replacing often if you jump big or get them wet. A sloppy motor bearing will never mesh right.

[@Angel-dv2kf]

Where’s the motor bearing?

Make sure you clean screws, greas it then put it all back together

I purchased an XMaxx over the summer and went through pinions and spurs like mad. The pinion kept slipping off the shaft, leading to catastrophic destruction of the pinion and spur. I used every flavor of loc-tite in existence to no avail. It turns out, the flat spot that the grub screw would mate with was actually slightly tapered. I confirmed this by measuring it with calipers. Heat cycles would just push the pinion right off after a couple battery runs. I didn't have the tools to properly re-machine the flat, so I drilled a divot in the shaft for the grub screw to seat into when it's fully screwed down. I haven't had a problem since. The downside to this is you're likely limited to one brand of pinions, so they all have the grub screw in the same location.

[@wyshtechairsoft]

Ive heard of this happening if you dont have the motor slotted into the chassis correctly. Though great idea of fixing the problem!

[@Todd_G_FPV]

Thats what I did too and your right about being stuck with one brand but honestly I found one I really liked and thats all I use

[@wyshtechairsoft]

@@Todd_G_FPV What brand do you use?

[@Todd_G_FPV]

@@wyshtechairsoft Robinson racing but thinking of trying a arrma D bore pinion as I've heard they stay on really well. Found a 16 and 20 tooth D bore for like 5$ on ebay for both

[@wyshtechairsoft]

@@Todd_G_FPV If you dont mind me asking. What gear ratio are you running?

Excellent video well done 👏l just Purchased a xmaxx l was wondering about the pins all good now thanks 😊

[@wyshtechairsoft]

Anytime bud! How are you liking your Xmaxx?

[@Thrillerwiththebeanstalks]

Great video!

[@wyshtechairsoft]

Thank you!

[@redblue40rc33]

With pins set in correct position, does yours have that bad cogging sound? Mine is stock......... 18/54 or what ever the☝️spur is .. biggest one anyways.....that plastic housing guess has alot of flex for such a big rv truck...my outcast 8s, smooth as butter...roll tires with one finger...Xmaxx..takes 2 hands to turn all 4 wheels..both our X-Maxx's like that

[@wyshtechairsoft]

This Xmaxx cogged at well but it wasn't bad. Ive long since sold the RC but it was running like new after repairs were made. I bought this thing used and busted so I got a really good deal on it.

[@teamvegarc]

Awesome work 🏎💨💯😎

[@wyshtechairsoft]

Thank you bud! Let me know if you want me to cover anything.

[@loiswiser9201]

Wow! Good job!

[@wyshtechairsoft]

Thanks!

[@opticsavage2122]

i did this and it instantly blew apart my pinion gear, but it did work the second time

[@wyshtechairsoft]

Must of been a bad pinion?

[@budders7660]

What size is the allen wrench for the set screw? Thanks

[@wyshtechairsoft]

I believe it was either a 2.5 or 3mm

[@evanvavoulas4011]

Awesome thanks for the help

[@alcurrie7620]

6 months later, how does that gearing hold up?

[@wyshtechairsoft]

Great! Haven't had any issues since I did the replacement.

[@Sheldinator]

The smaller the gears the faster or other way round?

[@wyshtechairsoft]

Yuppers! At the sametime it increases the stress on the motor/esc.

[@jonathanboyer8723]

The xmaxx has optional pinions and spurs, for the spur a smaller gear is faster, for the pinion larger is faster

[@adamcooper7212]

What brand is that new spur? Traxxas?

[@wyshtechairsoft]

Yessir!

[@SerJeepRadiocontrol]

buen video amigo, buenos detalles!! 😁😁😁+1

[@DashzRight]

How do you end up with such nasty situation to start with?

[@wyshtechairsoft]

I got it as a trade with another RC for a 1/5 scale hpi I had. Anyway, I discovered the previous owner swapped the pinion gear and didnt set the motor correctly.

[@stevenjacobs270]

yes okay nice video not full the pind need on E correct what hol you need on the motor self???

[@wyshtechairsoft]

It depends on the gear ratio you are going with. Move the pins to what gear set you are going with and then place your motor back into the rc on the pins. Hope this helps!

[@rcboy4652]

no need to put grease? mate?

[@wyshtechairsoft]

No grease is needed. Traxxas doesn't recommend it.

What do you mean set the screws?

[@stevenjacobs270]

i use 18/46 and i broke on 5 sec and i set the pins on E xs i set back 18/54

[@pythonman8103]

As long as this has been an issue, you'd think traxxas would have fixed this engineering issue by now. Traxxas quality is going rapidly downhill!

[@oscarmike131]

Geeezus dafq did you do on that spur, chew on it? 😂😂😂😂😂😂thats shit all fucked up!

This was a XMaxx bought used. It was a deal I couldn't pass up. haha
