The thickness of the brass weight is 2.0mm

The thickness of my tungsten weights are 3.25

Here are the pictures.





Looks good!!! I guess if the tungsten was the same thickness as the brass it would weigh about twice as much, very cool.

EagleAlloys quoted me $285 dollars for a piece big enough to make 2 battery trays. I think I will stick to copper and add 30g some where else.

Those guys are some what cheaper

You can always make a brass plate thicker up to 3.25mm maybe bringing the brass up to about 65 maybe 70 even and idea for any of the cars.

IMO, copper-tungsten alloy is a better choice, easier to machine and not as brittle as tungsten. I don't think the tungsten tray will survive upon a heavy impact.

That is what I thought.

The copper trays I made for the MRX5 weigh 60 grams.

Most of the tungsten is not pure, mine was MT-17 grade. so about 90-92% the rest is nickel/steel.

Lots of different grades to pick from. I was looking for the most tungsten i could get and still have it be pretty easy to work with.

If the impact is hard enough to break it, I would like to think its going to break a bunch of other things to. I should be safe until ft myers, no cars falling out of the sky in front of me.

Thanks, will look into it asap.

The trays look great, I already know I'll have to get some made soon, full tungsten parts how cool is that?

Will those heavy (and torsional rigid) trays prevent the chassis from flexing in the floating top deck setting?

Prevent. No

Stiff some. Yes

I can still flex it / wiggle the top deck

Go with the kit setup, Make sure you thread lock the screws for the brakes and everything else will go together nice and smooth, The MRX5 handles amazing out of the box
