I'd be really interested to know the weight and if possible, weight distribution front / rear and left / right if you get a chance and find your scale.

Thanks Justin, I'll do the same.

Thanks. I think with enough titanium etc we should be able to get it down closer to 1600.

What is the Roar legal weight limit for 4wd buggy? Anyone know if this applies in Australian racing?

1613 g is the minimum in oz, I think it's only enforced at sanctioned events, to drop weight I use alloy screws, they are a lot lighter then titanium but not as strong.

Yeah, I thought about alloy screws but I have enough instances where the heads of even steel screws round so am reluctant to try them. Especially given how tough the Kyosho plastic seems to be. I guess aluminium screws would be about 50% lighter than steel ones vs about 30% for titanium.

I emailed MIP about the possibility of some aluminium out-drives, dog-bones etc but was informed that they have no plans to make them for the ZX6 at this stage. Unless they got a lot of interest.... come on guys!

I'm actually thinking about trying to make my own alloy drive-train bits for some fun. Just need to get my hands on a Mill... have a lathe but almost everything seems to need at least one milling operation!

Kyosho do light weight diff outdrives for the ZX5, diff parts are shared.

MIP do light weight shafts for the RB5/RB6 range, rear shafts shared.

Plenty of ways to get the weight out already BUT try it a as it is, unless your struggling for acceleration in stock classes then carrying a little extra weight low down only helps plant the car.

People often say that extra weight can be good, but I'm just not a believer in "heavier is better" regardless of the conditions etc. I'll try it out as it is before I go too extreme though.

The hub carrier has a little bit more material top and bottom on the "6" the king pin screws sit in a recess top and bottom

A pic might explain it abit better

This is the "6"

This is the "5"

I started building my zx6 and being my first 4 wheeler I did something pretty stupid

I was looking at the arms and thought 'gee I dont like the look of those mould points' so I snipped them all off and ignorantly carried on until I reached roughly halfway and it was time to put on the swaybars...
