    First Arrma build Big Rock 6s

    I’m just getting back into this hobby. Recently bought my first arrma at my local hobby shop. Decided to go with the 1/7 Big Rock 6s. Very happy with it so far. To me planning, upgrading, and wrenching on these things is just as fun as running them. I still have a lot to learn about this...

    Big Rock Bigrock CC V2 ??

    So I was just thinking (and now my head hurts) What's the Bigrock CC 3s 1/10 V2?? V1 is the Blue body, chrome bumpers and rims V2 ? V3 is the Black body, black bumpers and rims plus a 1.1" wider stance. Current version. So was there a V2 released? Did Arrma miss one or am I missing one? 🤔 🤷‍♂️...
