Thanks brother I really appreciate it much deserved reward finally to join the 140mph club

OK so added some more beef to the Bigrock build. New CNC ring gears and inputs with the new diff cups. Also got the @3d-rc.myshopify.com 150A esc mount installed and spektrum 150A 6s esc with upgraded powerhobby fan. Going to run it on 3s first bash or two with the new gears to break them in. Then will be swapping the 3s motor to my Granite and putting my Hobbystar 4068 2400kv 4s motor in the Bigrock Also pretty sweet the new CNHL packs I picked up match the black and orange Bigrock perfectly

OK so after snapping a rear turnbuckle yesterday went ahead and just upgraded the rear set to the Typhon 6s set. Should hold up a lot better being a thicker shaft and also the spindle is all the way inside the ends. To make them fit just had to replace the smaller pivot ball with a longer one like the t2t pivot balls and trim to 10mm, also had to grind down the longer metal pivot balls on the other side a little but to fit in the hub.

Recently was sent a new Hobbystar 4068 2400kv from RCjuice for the Bigrock. After work last night soldered up 6.5mm bullets on the 150A for the new motor. Now just need to swap out the 3s spektrum motor for the new Hobbystar and she'll be a 4s beast like my Granite

Latest addition is some custom made beefy CVD driveshafts from @HZRDOS in the rear. Should be set now for some 4s mayhem will see if I pop the fronts then I'll add them all around but thinking the stock fronts should hold up as even now they aren't even stretched at all yet after running 4s a while.

Those are gonna hold up to whatever!

That's what I'm hoping, definitely quite the beefy rig for sure

Prob a rookie question but are these still the only way to have good CVDs?

I'm not sure as these are the first CVD's I've had. The stock ones by themselves should hold up well these are just even stronger how they are made.

Nice rig! Have you done a speed test yet? I've been thinking of doing this to my BRCC.

Thanks! No haven't checked speed with it but would guess it's close to 60mph give or take.

Sweet! Ohh few questions. What hubs are you using for the Badlands? I'm using HR 6mm hubs and might change them. Also, my RPM typhon arms are slightly bowing. Are yours?

I'm running the Integy hubs but I had to trim the front driveshafts to make them work, if you go back in the build thread I believe I posted about it. For the RPM arms I'm sure mine are bowing a little it's common for sure. You can pull them off and boil them to straighten them back out

Have since added Kraton EXB front shocks on rear and Mojave EXB front shocks to front.

How do you like this? Are the front shocks too long? Are you using the springs that came with the shocks or custom springs? The measurments are 108 mm front and 115 mm rear? Compared to stock 101 mm front and 115 mm rear.

I found this interesting as well. Years ago I bought Typhon 6s shocks for my BRCC. They were fine until I put the Typhon RPM arms on. The truck sits a bit too low in font for my liking.

I think it's perfect to be honest really like the shock setup how I have it. Front shocks I don't feel are too long and yes using the regular springs that are on the shocks. I also like that the front doesn't sag like with the stock 3s shocks and they absorb a lot more impact and rough terrain. I run this setup on both my 4s Granite and 4s Bigrock and have noticed a big difference especially with big sends off my ramp and bashing around on bumpier/rougher terrain. Rigs don't bounce all over and roll super easy and take big sends like 20ft high all day. Have yet to break a rod end or bend a shaft either. But being on the lighter 1/10 rigs I'm not surprised as I've not even broken many rod ends and not sure I've even bent a shock shaft with my 6s rigs that get sent 30+ft high and all beefed out with m2c so are heavier.

Finally got around to installing the front CVD's on the Bigrock. Now has the beefed up CVD's on the rear and regular CVD's front so should be solid and take the 4s power all day

Any problems with snapping wheel axles? (Not the driveshafts, the axles on the end.) With Hot Racing extenders (and aluminum front steering blocks/rear hubs) I was snapping wheel axles all the time. The less flexible CVD axles snapped even more often. It's why I stopped using the CVD's.

Looks like you're using the M2C extenders. They're very similar in design to the Hot Racing extenders, they have that nut that covers the wheel axle and may help prevent it from snapping. If they do, maybe I can try CVD's again.
