Big Rock I’m a Noob that needs help how to fix Big Rock

[Diggery]

I’m seeing a set of a 5.5mm and 7mm nut driver wrench. The 5mm nuts that are referenced in this link, will the 5.5mm wrench work? When it says 5mm in the link does it really mean 5.5mm?

Edit: Nevermind, I think they are different and I would need the 5mm wrench

The wheel nuts are M4 which means they have a 4mm diameter thread and that requires a 7mm tool to fit over the nut.

The M5 is a piston top nut so you'll need a 5mm wrench if you bend a shock shaft. If you get a combination wrench then you can use the open end on the turnbuckles and the closed end on the piston nut.

Thanks everyone for your help. Don’t think I would have known what to do otherwise. Certainly wouldn’t have known about that missing screw! My 9yo helped me fix it today. Just went along with the video, there were slight differences between his car and mine but easy enough to figure it out. Thanks again. Posted pictures of the repair.

Have a V3 Big Rock BLX and it did some cartwheels the other day. It appears that the rear arm is broken? I posted some pictures, is that the only thing it looks like that I need to fix? What tools will I need to fix this? Thanks.

I’m thinking I should be able to find some tutorials how to fix on YouTube. I’m just not sure what exactly is broken and what tools I need to get.

@Lucky Socks - if it is the rear arms then part number AR330516. For the front AR330443. For the pins or screws use AR330456. Also use this link for an interactive view of the Big Rock - https://www.arrma-rc.com/en/interactive-exploded-view?pid=ARA4312V3
