Awesome truck and run, I have owned two X-Maxxes in my life so far and last month i fully restored my current one only ran it once so far. I love your truck and i'm planning on building my own Ultimate X-Maxx someday.
500 front 20 mill with 1 ear plug and 300 rear. Running max 5 1100kv 25/35. Your mod 1.5 sounds terrible compared to mine. If you have the GPM spur gear it has that little bearing that the shaft goes into. That bearing usually blows and the shaft will spin funky creating that noise, even though it will look like the mesh is fine. It’s happened to me a number of times and I know that sound.
Technically nobody can build an Ultimate exactly as they are from Traxxas, Xmaxx is my favorite R/C, So tough easy and inexpensive to repair (stock) No R/C can take the abuse a Xmaxx can!!!
Maybe the gear of torque biasing diff is slightly touching your centre drive shaft? Its hollow so that might give that ringing sound. Check for wear on the drive shaft.
Love all your content. My green Ultimate is all stock. Wheelies great for a half mile. All around great driving experience. I drive similar to you, pretty easy on it considering what other people do. My motor runs hot. Melted the plastic end caps and bearings first run. Now I drive it even easier but 170f degrees. Never has my Kraton 8s Castle 800kv Xlxv with no Fan gotten warm? Would like to have a stock spare motor for my XMAXX if you have any used ones you’d like to sell cause I’m worried about it. Got a Hot Racing 50mm fan to install but not confident it will help. Any suggestions, I really don’t want to upgrade motor but will if this keeps running hot. I’m across the river half hour north of Detroit 😬😅
@@jimpalazzolo6013 Mate it’s EXACTLY the same for me !! 😄 I’m about to buy my first Xmaxx and I’m actually checking what are the parts I need to buy with, to avoid any issues… I’m not an expert on these models too… I’m learning and these new RC are very very cool. I have a LOSI SuperBajaRey2.0 by the way. I can’t decide myself between the new 2024 standard Xmaxx and save money or buying the Ultimate… The only thing I know is that I don’t want to upgrade the combo, I want to keep it stock. These machines are WAY ENOUGH powerful for me… And I don’t like doing flips etc. just nice clean big jumps… I don’t need overpower. I’m a bit concerned by your experience now… What kind of temperature do you have where you live ? (I’m living southeast coast France, the hottest area of the country……and hot summer is coming very soon… here the average summer temps are 30-40°C)
@@1980VINZ I already have 1 Hot Racing 50mm fan already to install and I’ll let you guys know temperatures, give me a couple days. Maybe fitting 2 of those fans will be the fix. Gonna try that also
I have an xmaxx that I run earplugs in center diff and factory front and rear weights. Has an 1100KV with mod 1.5. 25/35 and no fan in motor. Runs fine. I tried a center diff spool and that's only good for speed runs. Snapped alot of cups just launching
Earplug is the way to go it almost locks up the center diff but still has a tiny bit of play but it will really save your center diff if you land on on power and better POWER response! Love your videos! Are you planning to do more videos about the Arrma Kraton ExB v2?
@@Duke373 Kevin Talbot crammed some wax ear plugs into a differential for some reason. he called them silicone but they looked like the mold-able wax type to me. im trying to figure out why ppl dont just use more grease or at least dry graphite.
I like 20 million topped off with an earplug. Gets you to about 30 million. You need that minimum if not full earplug because of the how heavy it is and the extra power you’ve got.
I know that fat girl is handling the extra weight well, but you might consider pairing that xlx2 with castles 1721 1260kv motor, save a little weight and up your kv a lil bit 🤔

Just keep a sandbag in the back of your truck. You can lay the sandbag in front of the jump and it will stay perfect
Exactly what I came here to say.

Sounds like its chain driven or like something loose ringing like a bell in it, but running good
Does that ESC let you adjust timing? Since everything's running cool you could crank up the timing and see if that gets you what you're after.

😂😂😂alredy i build one and its very good
@@Margaritakola Yep I'm sure it is!!! have fun and enjoy, Xmaxx is awesome!!!!
Great runnin...You.could go with stiffer springs in the rear, with no preload for better wheelies 👍🏾

And why not put the XRT fans system ?
Thanks I’ll check into that. I’m new to these powerful 8s machines, been running nitro since the late 80’s😂

Sounds like the drive shaft hitting plastic,gears sound unique.
I kinda like the sand bag idea
I pretty much put the pinion and spur as close a possible with play and it's perfect
Awesome Dude! The mod 1.5 gears like to ring. The mod gears are an art form and not everyone likes them. Have fun buddy!🤘👊🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥

Where did you get that ramp, it looks perfect for the X-MAXX.
Put some little rubber legs on the bottom of the ramp and add a bit of weight. It’ll stay put for sure. Good luck 🍀
That thing jumps good 👍
So I've never had a castle system there is no sort of punch setting on the system
I run 2 million in the center
diff wheely nice and don't diff out all the power to the back wheels
I can't pinpoint what it is, but that didn't sound too healthy. I'm wondering if it was a driveshaft/dogbone sound rather than gearing related.
They all brake funny how its the small jumps sometimes
Center diff probly not full
Hi I'd put a 1100kv in 👍

Man that sounds horrible
1100 Kv sounds like a good plan for this truck. Will be great to see your Losi 5B running on 12S!
The cow rc wipes are the best!
