Crawler Canyon Presents: ICFTW Vol.16. Ep.4, doing the improbable

[@Loose_Lucy]

Cosmic Charlie is what comes to me when I watch this

[@adamrodgers2377]

If that were mine, I would name it "Rock Spider" cos that Rig sticks to the rocks like a friggin spider!

[@jackhando5465]

Ya built yourself a frickin Billy goat. It's just so planted. Just like those goats that climb on dams to lick the salt on the sides. That's what that truck reminds me of. I wouldn't cover up the cantilevers. They look awesome!! Great video, great build!! Bucket chair with foot pegs...too funny

[@Gibsonlife573]

I love the way the spare tire looks on the back of it

[@derrickhays3627]

The force is strong with that one! Black alchemy can not be explained only enjoyed, you have convinced me to put cantilevers on my 10.2 love this build thanks so much.

[@Br0rB]

It turned out so great with so little extra put into it. I'm impressed! I have a 10.2 Raw builders I have built up with a similar cantilever kit (probably identical) and a hardbody. I got the cantilever setup solely because I didn't want to cut holes in the body. Seeing how well this build turned out, I'm thinking I have to try and steal some of your ideas, and turn it from a decent trail truck, to a functioning crawler. The cantilever suspension defintely needs some stiffer springs and heavier oil, cause that thing is pretty much just flopping around right now. And I need to do some sort of machining similar to what you have done. I also need to put that heavy hardbody Jeep on my RGT. and get me a much more light weight body for it. I have a cliffhanger body on the way. That might work. I think figuring this thing out, and build it to be a nice crawler, will be a project for this summer. Especially since you have already done most of the thinking for me. 😉

[@Lured-in]

During the video and your comments on how strange the truck is, it seemed that it has kinda named itself “Strange Brew”. I like it, what a great looking truck!

[@jmnaylor]

I want a truck like that without the headaches! Awesome work man!

[@CrawlerCanyon]

I think what went a good ways toward maintaining some semblance of sanity while working on the UGRC kit was working on this, because every time I made a change it worked.

[@clarkb1900]

Man.. this thing is ALIVE. :0 -Creature?

[@CasperRc81]

Be cool if you could tig weld a nut onto the end of a dog bone cup and see your spare rim spinning in operation and from the sour cover knob of the body hole cut out a 2-3mm center line down so the body splits around the dog bone cup removing the body etc. Also you’ll be able to adjust the slipper clutch. I personally like a working slipper I find that it prevents too much wheeling back on super vert angles dissipating some of the transmitted torque from the rear tires. When you slip the pads a little and let off they tend to warm up expanding the slipper disc and creating traction.

[@adamrodgers2377]

That is a good looking Rig. I think it would look badass with just a Fuel Cell and no bed, I don't know if I could cover that rear suspension. Awesome video as usual! 🤙🏼

[@jimbocreationsbu8203]

with the red Diff cover and blacked out look-he should be named "Black Widow"-especially how spider like ability-maybe cut a small spider sticker for the hood

[@jayleeson8517]

For the hole in the body where the spur shaft exits. Can you make a brass winding key that will spin with the drive

[@jord001]

SO now you have it climbing like a spider i think its time to do the "which tyre is best" test for this rig, im sure the fake ruptures or approach tyres would perform on this truck id be testing them anyway. I did originally think of the name copperhead as you were painting it copper inside but now thats gone out the window. Definitely black widow or darth climber, something along those lines. Another great rig and another great video, I cant keep up the with builds. I havent even started cutting my new frame yet and you have 2 whole rigs built lol. Kudos!

[@CrawlerCanyon]

Tarnation, I shoulda just painted it copper and been done. I have a stack of Copperhead stickers. Yep, tire testing to begin shortly-- not that I'm mad at all at how well a set of basic Canyon Trails are doing.

[@MThompsonjr115]

The reason the rear is so soft feeling is due to the angle of the pushrod relative to the shock. If the pushrod was 90deg to the shock, you’d have a much more consistent and normal feeling shock. The fact that the pushrod gets closer and closer to parallel, to the shock, you’re losing effective spring and damping rate. Also the ratio of the bellcrank lends itself to creating a softer/less damped shock. If you flipped it, you would probably see an increase in effective spring rate and damping. Still not as much as could be had if the pushrod was vertical.

[@CrawlerCanyon]

Gonna have to go with the compromise on this one. The shocks don't work with the bellcrank flipped, the pushrods go from having too much mechanical advantage to having none. This would also put almost the entire shock body above the rails, which defeats the whole point of it. I'd either have to take a good inch off of the wheelbase, or extend the chassis an equal amount to get the axle to a spot where the pushrod would be more vertical. I think there will quite likely be an LCG build in the future where I build cantilever-specific rails, so I can get the exact shock placement I want. I can live with having to power down descents with this guy, because the performance everywhere else is fantastic.

[@gregmyers3389]

@@CrawlerCanyon Also, the main point of cantilever suspension in off road application is "travel" gains... i.e.-more overall suspension travel with the same shock (usable travel) the "bellcrank"s pivot and mounting positions should give more travel with the same shock or even shorter. Those pushrod positions are jacked. This set-up is incorrect. No hate , long time viewer (remember the race track) love ya man, I stayed BECAUSE you changed to the "canyon" format.... but you should check out some more info on suspension designs. There is a lot of good books and articles out there on cantilever suspensions. Keep being you man, have fun!

[@CrawlerCanyon]

To borrow a paraphrase, "if it's incorrect and it works, it's not incorrect."

[@MThompsonjr115]

@@CrawlerCanyoni didn’t think they would work flipped, just an example. Not hating on the setup, I think it could work even better with some tweaking. It definitely looks cool and allows you the room for more activities lol. My dad and I watch your videos often. He’s scratch building some crawlers of his own now.

[@ryurc3033]

Flipping the bell crank isn't the fix, the fix is moving the bell crank rearward. Get the pushrod geometry right and the rest will sort itself out.

[@brianargo1659]

Do u think it may have been the mesh that was making the cherpping noise because the black dust had to have came from the spur. Maybe the screws on the motor mount may be lose and making the motor rock back and forth

[@Gibsonlife573]

I think it's the first time I've seen you flabbergasted like this

[@klampykixx]

I can see its been aaid a couple times already but i have a slightly different point to push In regards to the angle of the rear pushrod relative to the rocker, can you flip the whole assembly so the shocks are forward of the rear axle ? I feel like reversing thw direction of the rocker would put it more inline with the suspension travel. Secondary benefit is bringing the weight , although minimal, of the shocks forward and more central . Curious to hear your thoughts on that.

[@CasperRc81]

Wonder if they have shorter cam arms. That’s an nice clean build body looks nice.

[@machinedred]

HOT 🔥 was it the motor bearings?

[@snoprosledneck88]

When he caught himself it made me think of a cat so maybe the name Black Panther.

[@TheAmericanUhate]

What if you reversed the center cantilever bracket to be closer to above the axle so the push rods are more vertical, and flip the shocks to face forward on the chassis instead of out the rear?

[@CrawlerCanyon]

There's not enough room on these rails. Maybe with a 60mm or 70mm shock. I' now thinking about a future LCG with rails that are cantilever specific, so I can tune to my liking. For a bolt-on Amazon kit on stock 10.2 rails, I think these are doing well enough that I don't wanna redo the whole thing just to improve the bench feel. I can't see the on-rocks performance getting much better as is. I'll likely try some different tires, but this guy is pretty well set... for now.

[@meirdeaph]

Awesome possum

[@Truckguy41]

name for the truck Dr strange :) very unique the way the suspension is working, the rear bed could do a flat wood bed with a big ? in the center of it lol

[@robertvukonich5003]

Super odd how that works makes me want to try one. Curious what it would work like on a ifs

[@thindigital]

So does it follow that front cantilever suspension would also give the black magic weight transfer thing to the front, is it even possible?

[@CrawlerCanyon]

Based on the amount of time I spent today trying to set up this one "correctly," I'd have to say probably not.

[@thindigital]

@@CrawlerCanyon can't blame you for that, there is a dark side to the hobby where the fun has gone and the struggle is all that remains. I know I'm there when I keep dropping tools cus palms are sweaty. Moms spaghetti.

[@NTX_RC]

What are you using for rear body post mounts?

[@CrawlerCanyon]

I took a servo mount (I think from a Redcat) cut it in half, and used half on each side. Cut down two of the bodymount posts from the kit and screwed them into the servo holes. I think I covered it in Episode 2? I think?

[@Gibsonlife573]

Could this possibly be your most capable rig

[@snoprosledneck88]

I would love to see this truck on some tusks or trenchers. Ruptures would be awesome but the additional tire hight might throw off the tune you have.

[@neildaniels5443]

Ya gotta call him Dr Strange, imo leave da extra tyer off.

[@FaithSaraG]

So, cantilever all the things?

[@CrawlerCanyon]

I think what we get from an Amazon kit is what we should expect-- I now have at least the mental plan for LCG rails specifically set up for cantilever. I've got some super-skinny MST shocks that have never found a home on anything else, and I think would be perfect for it. When it will happen, who knows.

[@ericsmith3317]

Miracle worker with a crawler... Doesn't have the sense to get out the piss ant bed 😂

[@CrawlerCanyon]

Oh, they're everywhere. One day, not a single ant, then I guess the temperature hits a magic number and we got thousands. They're losing real estate to rocks, so joke's on them.

[@JIPPERR_1]

Gotta call this one Vader

[@johngleason9667]

Definitely name him Doctor Strange

[@ryurc3033]

Aaahhhh! pushrods flopping in the breeze......it's the same thing as laying down the shocks too far. Might as well not even have shocks on it. The torque twist alone would drive me batty

[@Team_ReVolt]

LIZARD, his name has to be 🦎 35:46

[@dkmgm2011]

You're killing me smalls. Double spring the rear shocks. It's not rocket appliances.

[@CrawlerCanyon]

Not enough spring + not enough damping = kinda okay Even the right amount of spring + not enough damping = it all gets worse

[@dkmgm2011]

@@CrawlerCanyon diff oil my guy.

[@derrickhays3627]

P.s how about "Darth Crawler"

[@SivartCustomRCs]

I do like the tire on the rear, but i feel it may ruin the balance you have now. As for names, cunudrum or black magic came to mind. The cantilever suspension is awesome, i have a set on my hardbody TRX4 and it pulls lines that others cant. I also wish i knew exactly why. Im in the same mindset as you. Somehow it transfers weight different than conventional shocks, especially when the vehicle is vertical.
