  • Super fun!
Color: White
Comparing the Big Rock 6s to my modified Granite, it’s a lot easier to control and is faster & more fun to use. I didn’t even want to use it since it looks so nice. It’s sad that Arrma discontinued this r/c car. Get it while you can before they’re all gone.

  • Its FAST and TOUGH
Color: White
This is a great truck and the first product I have ever given 5 stars. I own over 50 different RC cars and trucks. This truck is really built tough. I have run 5 packs through it, I was launching it 20+ feet in the air and crashed it a few times and nothing broke. I was shocked especially when it landed on its front left wheel. I checked everything and its fine. The truck is also crazy fast which I love. It took a few adjustments but I can go full throttle and ride the wheelie bar pretty straight down the street. I highly recommend this truck. ... show more

  • Epic
Color: White
Man did I get a deal on this thing think it ended up being under 500 because the white color had a extra coupon but I received a red one exactly what I wanted this thing is so quick for the size scared I'm going end up in ER from ramping myself lol. I put big snow tires on at the end of winter and wow powerful enough to drive on water was fun as hell. I did have some issues with it dying prematurely seemed to be from battery droop so I tuned it with the programmer working like a champ now. ... show more

Color: White
This is not a basher, arrma is lying to you. DONT WASTE YOUR MONEY ON THIS. This was a very fun truck for 10 minutes before the shell busted apart during a crash down a hill. My $80 haiboxing can take the same jump with no damage but this truck is supposed to be built for bashing and it does this. I'm very disappointed ... show more

  • THIS TRUCK IS A TANK!!
Color: White
I left no stars for battery life...it doesn't come with batteries. Left 1 star for beginners, because this is NOT a beginner's truck. The last negative thing I will mention about this truck, the tires are not all that great, they lack traction which isn't too bad if you like burnouts and shredding tires. Now...onto the good. I have been bashing this truck hard for over a week. (10+ runs). I've had many crashes with this thing and nothing has broke. Everything is still original. I put on my original Kraton tires (copperhead 2) and I finally got traction. Wheelies all up and down the road. Incredibly fast. I'm not a fan of spectrum servos but this one seems to be dialed in right. Chassis slaps on anything over 12 inches so I may change the shock oil. Between my Kraton and my Big Rock...I never know which one to play with. But if you are a pro or even intermediate basher, this is the truck you are looking for. I'd buy the truck again any day of the week! ... show more

  • Good but not Great.
Color: Red
The media could not be loaded. Keep your expectations low on this rig because there are a few things to consider. First of all it’s a beautiful truck and has some very good scale styling. On my first run, I was amazed by how much torque and acceleration it had. However, the steering travel is far from perfect. Felt sluggish at best. I swapped the steering servo and it “improved” a bit but not by much. The speed pinion improves top end but careful with the tire hubs, they “wear “ out rather quick. ... show more
