big rock

Hoping to find rear springs off a BigRock shock from someone upgrading. Really just need the springs but may take the whole shock assembly as well. Or maybe consider the upgrade myself if someone has a set of 6s shocks. Thanks!

Hello! I have a Arrma Big Rock V3 that has been heavily upgraded. I purchased a Hot Racing Servo Saver attached with a plastic 23T (spline adapters for 23 tooth (KO, Sanwa, JR)). On the cars first crash the 23T spline adapter that is made of plastic broke. Do they sell a metal spline adapter...

Hey everyone! I'm curious to know what the most efficient RPM range is for brushless motors. I am trying to build a big rock right now, and I want it to run cool on grass with a top speed on packed dirt/pavement of 60+mph. I've done some research, and I've realized that the more watts the...

Hello all, So to sum this up, I've been trying to make a very over powered big rock for a while now. I started with a TP 4050 2830kv D wind on 4s. It had a ton of power, but overheated too quickly, and really heated up the esc as well. I then tried an old Castle 1515 2200kv on 4s with a 24...

I have done a lot of Google searches, and even YouTube videos. Some people have reported nearly the same issue, but either the problem was the servo, or they never mentioned a fix. Here is my issue. I noticed the steering suddenly was sluggish, and at times unresponsive. By this I mean I could...

Im running a stock Arrma big rock bought 2 years ago, made some modifications but now my front tires are broken (cannot be used anymore, not even the rims). The only ones with 14mm on sale locally are the Traxxas 5877, they look pretty much like the ones found in the slash and slayer 4x4, i know...

I purchased the Amazon special 25kg servo for my BR (they finally sent the correct one) I've fitted it into the car, however the steering is reversed. I have adjusted the switch on the remote to fix this but I would like to know if its something I've done wrong and can it be fixed without...

Been thinking about converting my Big Rock V3 into a SWB for a very long time! The other day the rear input gear broke and I figured I might as well pull the trigger and order the SWB chassis to make it happen. This will turn it from a wheelbase of 327mm/12.87" to a wheelbase of 287mm/11.3"...

Hello! I am a complete newbie to the sport and looking for suggestions on what motor I should use. I recently purchased a Big Rock BLX V3 and upgraded almost everything with Hot Racing parts, M2C Racing, T-Bone Racing, and Spektrum. The car is upgraded tough and the only main factory item I...

Hello all, I was wondering if anybody makes a smaller spur gear for the Arrma 3s line. Thank you!

Looking into the hot racing king arms for the big rock but can’t find any info on anyone who has used them. Much thanks for any help

I really wanted to submit this to rig of the month, but I don’t have enough posts, so I’ll share on here instead :) I was never a fan of the original big rock body and wanted a “sporty” body. So I took a chance with this Raptor body. It’s the first time I’ve ever painted a body or used a non...

Hello fam, Anybody using the Pro-line powerstroke PRO6359-00 and PRO6359-01 shocks for the big rock? How do you like them and what oil weight can you suggest? I drive mostly on bumpy grass fields, dirt, and street. I don’t do the crazy jumps. Thanks fam

Hi guys, I am curious if anyone has an experience similar to mine. I got the big rock a couple of months ago and it came with wobbly wheels. I'm not talking about a wobble as in slop where the wheel has some play. I'm talking about wobble when the wheels are turning. I have replaced the tires...

I have had my Big rock for about a week and I am having some issues with the throttle lagging and reverse not working without engaging the reverse at least twice. Also noticed yesterday that range on the transmitter has reduced to about 200 ft. Seemed to be fine the first couple batteries. I...

After a complete rebuild following a catastrophic crash that left this lady in two separate pieces, I just took her out for a quick run in big open a car park round the corner. We have just had storm Eunice pile through the UK an everywhere is soaked and waterlogged so I kept her largely on road...

...out on a bash and at the end of the battery, the servo went unresponsive, to both: L/R steering and trim ...I'll be engaged in disassembly to source the issue... ...sadly AF won't accept MP4 files and I have no idea how to alter the format in which my phone saves videos... In the video you...

Hi Fam, Installed the hot racing bell crank with the hot racing servo saver and a new 25k servo. After installing the HR bell crank, the screw on the servo arm is hitting the chassis and not allowing full movement. Has anybody had that problem? I had to reinstall the original big rock bell...

Got myself a new body and a few upgrades. Had to get a new servo, stock was not powerful enough to turn the massive tires. Painted some parts. Added a Granite bumper set. I'm happy with what I have done to it. Now I just need warmer weather in Wisconsin to drive it longer then a single battery...
