Arrma Bigrock 4S Upgrade Test Drive - Did It Survive the First Run?

In this video, we take the Arrma Bigrock to the next level with some insane upgrades and put it to the test with its first 4S run. We want to give a special thanks to Turbo RC for the 4S upgrade that made this possible. The upgrades include a Spektrum 2400kv 3668 motor, Spektrum 120 amp ESC, and a metal spur gear. We also added a Custom RC Upgrades 7075 motor mount to ensure the upgrades are secure. Join us as we push the limits of this powerful RC truck and see how it handles the upgrades. From the upgraded motor to the new suspension system, we'll show you all the modifications we made to the Arrma Bigrock. Don't miss out on this epic adventure and find out if the Arrma Bigrock can handle the upgrades and survive the first 4S run!

[@granada012000]

[@ChriswithaCrc]

Don't it just buddy , shame it failed at the end mind by hey ho upgrades on the way bud .

[@chelmswoodjunction]

Hi Chris Yet another brill entertaining video for us all to watch especially me just starting my 12hr night shift. After watching the upgrade video that is one mean peace of kit great conversion. I'm looking at my next 2 cars a second hand hpi firestorm and then a new arrma infraction 3s. Hope you and the family are all well. Peter

[@ChriswithaCrc]

Hey Peter , Hope your well buddy . Thats good that you got something to watch mate ! glad your able to take the time to watch my videos . Yeah the big rock is of my all time favorites. The 3s ranges offers so much flexibility , shame about the diff but hey ho lol all in the name of science . Oh a HPI firestorm yeah i would really like one of those myself . Having said that the infraction 3s has caught my eye lately , just not sure i fancy wearing out tyres all the time lol . Stay safe there buddy and hope that the family is well Chris :)

[@chelmswoodjunction]

Hi Chris's That's true about the tyres but I dare say if we shopped around someone somewhere might have a hard wearing tyre but then again we wouldn't just stick the car against a pavement and floor it. Peter

RC is fun, thanks for the video

[@ChriswithaCrc]

Glad you enjoyed it , thank you for watching really appreciate it ☺️

[@rcplaytime]

Awesome rip till the end dude, it ripped the 💩 out the diff,but that's the hobby isn't it, my lasernut is constantly breaking something 👍👍

[@ChriswithaCrc]

Thanks man , yeah unfortunately those composite diffs on the 3s cars just ain't up to the task at all . Well that means its time to upgrade hey 😂. You should do a few more lasernut videos bud

[@chelmswoodjunction]

Hi Chris What's next rc car wise on your shopping list???. Peter

[@ChriswithaCrc]

Thats top secret buddy lol :) all will become apparent in the future ha ha

[@SnoriRC]

@@ChriswithaCrc A FULLY UPGRADED VORTEKS? One careful owner?

[@ChriswithaCrc]

@@SnoriRC would love one .

[@SnoriRC]

Best beard in RC #PANTIPONDYFEST

[@ChriswithaCrc]

Ha ha , Thanks man , i wondered when your beautiful commentary would come though lol . Hope your well dude . Chris #PANTIPONDYFEST

[@SnoriRC]

Did you notice when you hit the puddle it stripped the diff. That extra resistance and drag under throttle melted it. Watch it back and have a listen! 🦻🏻

[@ChriswithaCrc]

@@SnoriRC 💯 buddy , was fine till then , got a 4s metal diff coming today so no more 💩 itself .

[@SnoriRC]

@@ChriswithaCrc that will sort it!! Rear I presume? I cooked the rear diff on my Vorteks just full throttle pulling a wheelie with those Jetko wheels on and that was on 3s 15t pinion so easily done. I like the outcast v2 4s line because they come with all metal diffs / spur etc etc - makes them pretty unbreakable other than the chassis - which thanks to CRCU should be pretty solid now. Great video Bruvva!

[@DanRussell-q8s]

When you upgrade to 4s it seems to me that the spur and diffs are always the first to go soon after .

[@ChriswithaCrc]

Most definitely agree with you on this , 4s diffs and metal spur and your golden! Stay awesome Chris 🤙🚀👊🛞😎

[@jensg.5832]

Switch to 4s on this truck you have to CNC everything

[@ChriswithaCrc]

Like what buddy ? Thanks for watching Chris 😎

[@jensg.5832]

@@ChriswithaCrc like both diffs, input gears, and upgrade to gpm drive shafts, basically whatsoever you can ads that is cnc steel upgrade do it, I had my rear diff only cnc for awhile and crazy enough it worked until I could afford the next, and yeah bro i like rc vids yours are pretty good, my channel is 541RC I do a lot of cheaper rcs and stuff, I do have a fireteam though I haven't posted a video in awhile because my mother passed away I just wasn't feeling it but here soon I'm gonna put up some more fireteam vids so, hope you get to check um out, Godspeed my friend 🙏

[@williamcabello2142]

What did you have to change now that you have the 4s

[@ChriswithaCrc]

This is not the same truck that I started off with buddy But if you look at my playlists there is plenty of information on upgrading yours to 4s Basically changed the diffs , motor and esc and drive shafts

[@williamcabello2142]

Ok I seen your videos I seen you have a 3s big rock I seen you change the motor to a 24 KV that's why I was asking you what else you needed to do I'm pretty sure you have to change the drive shafts and everything else that was just making sure that I have the same truck and I want to put it input I'm probably going to put a BLX 120 and just run it like that and upgrade stuff as it breaks I have metal diffs and metal gears

[@jimbar73]

just stick 18t pinion on this thing & save yourself some money

[@ChriswithaCrc]

watch some further videos buddy , the big rock is running sweet as a nut now on 4s system with a 20 tooth pinion . loads of upgrades Thanks for watching buddy Chris :)
