Not sure why they put it the other way around in the manual
This and many others. No idea why the battery posts/braces have been laid out the way they are, the instructions are super unclear and idiosyncratic... In some cases I've also used the brace posts holes themselves as M3 mounting holes for the blocks from below the chassis. Installation is a PITA...

You got it right. Just a question, aren't the chasis the same? Difference is it's black anodized. plastic are softer, maybe true cos I only broke the rear hub. Metals... I can't say because mine is still holding up. For the diffs you get gear diffs. And if you have the intention of getting the ready set please don't and get yourself the kit instead.

I was under the impression the ready set chassis was stamped vs the milled kit chassis, can't confirm this tho

Aren't all Kyosho readysets made in china? Maybe thats why the price is so low, quality cannot say never owned a readyset from Kyosho.

I didn't know the ready set are made in China. Never own a kyosho ready set before. Anyway durability if you take a hard crash/landing, chances are you will break something. Up to date I had the top cap of the shocks coming loose, bend steering linkage and broke a rear hub. Other than that the kit is doing fine.

Ordering some new tools for my RB6. I cant remember what size they are. I never look at size only color of the handle. I'm at work and cant check my tools that are at home.

What tools are needed for RB6?
1.5, 2, 2.5mm hex

What else?
