ARRMA Big Rock 4s 80mph+ Speed FREAK!!! overview and spool test...

[@davidcarroll2035]

You know what, I’m 61 now, and I came into this hobby for my Grandchildren. I’ve lead a physical life. Army, coal mine face worker, and until my body got screwed through major spinal injury I’ve always been an outdoor hunting type of man. All this technology and talk flies over my head. I’ve spent a considerable amount of cash already, but when I look at these videos I feel overwhelmed x

The 3s Arrma rigs are just top-notch on durability, modifications, and SPEED! Sick build Rich!

[@richduperbash2966]

Thanks so much Rey 🤗. Couldn't agree more Brother. It's easy to get consumed with 6-8s rigs and overlook how truly fun and capable the 3s platform is. 🍻🤙🤙😎💪👊👊

just got the big rock 3s 4x4 revision 3 today with 50c batteries and its literally insane.....i had a team associated rc10gt back in the day(15 years ago).....and i think this battery powered 3s would kick that nitro booty all day.....its krazy.

Best advice I can give you is to go against something you did here. Make that thing as narrow as you can. Go back to Granite arms and grab the Typhon axle stubs and hexes. It will make your straight line stability way better. 🤘🏻🤘🏻✌🏻

[@richduperbash2966]

Thanks so much Brother 🤗. I knew that when I went wide, but wanted her to be 50/50 speed and drift Beast 😍. My hope was to go more Go cart style so she wouldn't roll drifting regardless of speed. I might swap on the Typhon hexs as that was my original plan 🤔. If I can make her stay upright with Granite arms drifting, might just give it a go, but my spots aren't totally smooth either. Really appreciate the suggestions though. Your Typhon 3s GT build is on a whole other level 😱🤙🤙😎💪👊👊

Epic! I have to say for someone who doesn't play with Speed that much you do just as awesome a job as you're Bashing. 83MPH That's hot! I have a love hate relationship with speed. I love the fact that my Talion can run a solid 72 but I always seem to find things to smash into at Speed. I just destroyed it for the 3rd time and this time I have to defer to my Shop guys for the save. I trashed and twisted the chassis so bad that all the front has to be replaced and my very fine motor skills are gone. More OT coming but this is gonna set me back some. I'm thinking about gearing her back down to stock and running 4S instead of 6S all the time. No problems when I ran that way 50+ is fast enough for an old guy!! LOL. This is one of your best!

[@richduperbash2966]

Thanks so much Harry 🤗. This speed project has been super fun Brother 😍. I did the faster testing in this big lot specifically to avoid hitting anything solid 😱🤣🤣. Nevermind that I darted my Infraction straight into one of only 4 poles in this entire huge lot the last time doing speed passes and drifting 😝. So sorry to hear about your Talion Brother. It's deflating to see our rigs broken up 😞. I last felt it when I pummeled into that death rock with my newly built up Outcast 8s. Knew instantly that a total rebuild would be needed. Going 4s isn't a bad idea at all Harry 🤔. These rigs are still fast, fun, and super capable with that voltage. Especially, geared up a tad bit taller. Hope you have your rig back together soon. Don't sweat the occasional carnage. It sucks, but it happens to all of us my friend. 🍻👍👍😎💪👊👊

@@joshjohnson9167 gearing will depend on how much drifting you want to do vs outright speeds passes. That kv is a bit lower than the stock 3200. You'll have to gear taller for top speeds. I've found the stocker slipper (57T) paired with a 26 pinion works great for drifting on 4s. I now has my 27/38 spool set-up for passes and the slipper setup for drifting. Easy swap with separate motors and slipper housings.👍

That’s super rad bro! I’m trying to do the same thing with my Typhon 3s but it rubs when I put the assembly back together. Plus, it’s a bit wobbly too, I can’t seem to figure it out. How long are the screws you’re using? And which nuts? I appreciate the help Rich.

[@richduperbash2966]

The screws are very short M3 flush mount. Didn't get an exact length. Just long enough to secure some M3 nylon locknuts. You can oval out the slipper hub holes as needed to get the 38T gear and 2 hubs lined up before tightening the screws/nuts. Also, you can get the screws seated flush with a countersink bit if you're having rubbing on the slipper housing. 🍻😎💪👊👊

Rich Duperbash Thanks for getting back to me so fast bro! That helps immensely! I think being able to oval out the slipper hub holes should do the trick.

Have you had any issues with the hot racing 17 adapters losing up? Put a set on my big rock and the back driver side wheel nut is losing up after a short run.

[@richduperbash2966]

[@Wreckedekcoupe]

I'm looking to make a spool like what you did so I can use traxxas spur gears and the ease of not using a slipper. Are their any tricks to drilling the holes in the aluminum to make sure the spur is centered correctly?

[@richduperbash2966]

I recommend using that same 38T Traxxas gear for easiest alignment. It's helpful to use the gear screw holes as a template to mark the slipper hubs with a sharpie pen. Use a fresh bit to drill with. It's ok to oval out the holes if necessary to get the gear and hubs centered correctly before tightening the screws and M3 nuts. 🍻😎💪👊👊

[@Wreckedekcoupe]

Finally got the parts all together to make this work I was unsure of what pinion to use with the 38t spool. I heard you run 27 in the video after a couple times of watching it. Is that a good place to start or what's the smallest I can run? I have a 20 atm with the stock 57 spur and a hot racing motor plate.

[@briansmith773]

I’ve got a Kraton 4s I love the truck but I keep having problems with losing teeth on the rear diff Any help

[@richduperbash2966]

My best advice is don't overtighten your slipper clutch or run really big wheels. I found original Badlands 3.8 to be perfect 👌. Other tip is keep the rear input bearings maintained and seated properly within the diff yoke. If they seize or get misplaced, the input gear will lose proper alignment with the crown gear and your mesh will be lost. Lastly, make certain you replace the stock bearing shim if you disassemble the rear diff. 😎💪👊👊

[@afterrunrc9935]

Not sure if it helps but i had the same issue. I got the aluminum yoke from hot racing and no more issues. I believe my issue was the plastic yoke can strip out the thread for the screws and loosen up causing a bad mesh in the diff.

Hey mate, just wondering how you attach the esc ? Just double sided tape or is there a secret ? Cheers for the info !

[@richduperbash2966]

Hey Brother 🤗. Yes I used 30lb rated Gorilla mounting tape. I also Dremeled the reciever box/ESC mount flat at the mounting holes and counter sunk them so the ESC itself sits flush. 😎💪👊👊

[@richduperbash2966]

I cut the mounting screw tabs off my 150A ESC and Dremeled the stock 3s mount flat and countersunk the 2 M3 reciever cover screws. This provided a flat/flush surface to simply mount the ESC on the cover using 30lb Gorilla mounting tape. 😎💪👊👊

Thanks Brother 🤗. I always liked the V1 blue too 😍. I'm really hoping ARRMA will keep tweaking this platform with different options. A 4s Talion and 1/10 Infraction/Felony would be a huge hit.

my slipper clutch screw came un loosened, why is this? did 4s on it.

[@richduperbash2966]

That's just something that can happen with most any slipper clutch. ARRMA added a small catch nut to the back side of the slipper assembly. Best solution is to add medium strength threadlock to the slipper adjustment screw so it stays set. I run most of mine 1/2 turn out from fully snugged. 🍻

[@43rocket]

@@richduperbash2966 I put threadlock in there but it seized of the the movement of car?

[@richduperbash2966]

@@43rocket that's weird 🤔. Unless it got some into the bearings, the slipper assembly should spin freely once installed and rolled with the car. I always give threadlock a full 24 hours to set up. Make sure you put the assembly back in correctly. Might also check the motor and input gears are spinning without problem just in case you have a separate problem.

It could because they use the same chassis with same wheelbase.
