Scx24 Build / General crawler performance tips

In this video, we go over an scx24 budget build, focused strictly on performance. General philosophy on what makes a crawler good, and some specifics used and goals to shoot for.

Hope this helps someone. Gimme a follow. Go check out some other videos. My TRX4 Sport build is on here, along with videos of it in the TRXcellence series of it as it transforms.

I’ve been watching videos for weeks months even and have not found a more detailed / perfectly explained version of why a component is the way it is, extremely well done !

Thank you 100x. Finally a channel with proper info. No sales not pushy. Very informative. Its great to see for a newbie because it can be overwhelming trying to learn even the basics.
Please keep your info coming.
Subscirbed!

Thanks man great setup 👌🏻 running video keen to see the injora esc in action got one on the way 👍🏻

Really sick build. I just subscribed to your channel 👍

I find it interesting how you built this truck with it being so low slung and raked out in the front with an lcg frame. I have seen some crazy builds online but this takes it to another level. I like it. I wish I could show you some of the crazy builds that I have. I feel like once you are willing to cut on a Scx24 body, then you are willing to build something crazy that will crawl the best. My buddy I work with has a big collection of Scx24 but they are all scale builds and I don’t see the fun in that. I like cutting and modifying.

good information dude, i love your approach to building a performing truck, i will need to get a rear link relocation mount to mess with link geometry, that could definitely help with even a scale truck.

Great rig, soooo low!- be good to see this baby in action

Very interesting concept having the front links stretched out so much to get the weight more forward of the skid. I guess with the bulk of your weight in the wheels and axles, that makes sense. From what I've looked into, for crawling, the link geometry for anti-squat and anti-dive isn't a factor one needs to worry about. It only comes into play on high speed/fast acceleration vehicles.
Great detailed video!
Thanks!

Looks like a nice and low rig!
Looks very similar to my buddy's build.
I'm not a fan of that shock angle style, and also no springs (yours looks like it still has some though).
It's mainly just the suspension geometry that most people get wrong, usually good at some things but not others, not well rounded performance.
Thanks for the great video!

Man that thing is stretched! Nice tips, thanks!

Re: the section talking about weight position in relation to incline- It makes me wonder for these little rigs if keeping the 60/40 front to rear weight, but having more of the front weight sprung and as much of the rear weight unsprung would be more advantageous. My thinking, and this is just thinking out loud! :D But if more of the weight is sprung on the front, that would act more on the front springs, lessening or delaying the unloading on uphill inclines. Often seems these little rigs are so low in sprung weight, it's part of what not only makes them jiggle but also seems to limit what the shocks actually do. Not a lot of compression when static and under compression, they just push the sprung mass(body, chassis, etc) up. It's more the twisting force that compresses the springs then the weight.
Just thinking out loud though, so please forgive the ramble.
Would be curious to see what 1:1 crawlers weigh and the exact ratio of sprung to unsprung weight is. I'd be on the average 1/24th, the ratio is often too much unsprung and not enough sprung.
Again, great vid explaining your rig! Be nice to see more builders take the time you have to do a deep dive into the what's and why's.

That's a pretty sick little rig, Injora released some silicone tire inserts for the 24th scale and 18th scale crawlers, i use them on my 10 scale and they squish good like some normal foams but they keep the tire shape really nicely on side hills and strange obstacles. im not sure how they'll perform on the 24th scale stuff but i have a set of the yellow super softs on order hoping they'll increase the performance on my Enduro24 like they did on my normal 10th scale crawler

Play killer video my brother I do Big Boy Performance Stuff also on the SCX24 I do find it kind of troublesome though sometimes when you slam a vehicle all the way on the ground it can really cause you a heartache especially if your front end is a little bit longer I have found with the short hair with a short front end it helps to break over big time

[gbresaleking]

The tires look good besides the big mold line down middle

[weedfaya]

Super la video beaucoup d information importantes et qu on a tendance a negliger, bravo et merci pour les conseils ...

[payneja]

Great video and breakdown! Thank you for sharing!

[Gibsonlife]

Also if you want one of the best servos out there man he's got a budget friendly one and then he's got the servo beast and he's got the servo beast and Brass dudes products are on fire

[Gibsonlife]

I don't know if he still carries them or not but he did have a 4 mm extended Universal axle that I swear by I still have after beating them up forever they're still in great shape

[LMH]

Sorry I couldn’t find or hear what chassis that is so but do you could you tell me what it is?

[Gibsonlife]

Hey with them OG RC pin tires mofo has the island spacer kit you want to talk about heavy and it kind of balloons those tires up just a little bit actually they should be mounted on something like that kit of his it just makes them more like their normal size far as the width of the tire and there's definitely a lot of tuning you can do with what he has cuz you can get two brass rings and two aluminum rings 56 Graham zero offset hubs so it keeps your wheels tucked in there's so much that can be done with them or you can extend it with his three or six millimeter hub which you can get brass or aluminum
