And on a different project, I was impressed how GoMachV used a nitro Rustler bulkhead on his TRX-B and wanted to give it a try. You see in the pictures I didn’t get it right on the first try. This is just a scrap piece to test the hole locations, and good thing I tried it first. I got it right the second time though.

For optimum camber link positions you will want to raise it up about 1/4” or so to match the correct hawk/trx1/rad2/eagle bulkheads. It takes a little fiddling to get it right where you want it to be but so much cheaper than sourcing discontinued parts
Really hard to see in my pic but there is a gap under the bulkhead and a couple aluminum spacers

I was wondering why yours was raised up off the chassis. I did it this way because it seemed cleaner. But I will have to see how the camber links align and adjust accordingly.

When running it as you are, make sure you use the upper set of camber holes and the top hinge pin holes in the hub carriers. I have run them like that before and it gets you pretty close. With the trx3 battery box the height is set as it screws to the bulkhead.

Update!
Had some free time today and got one little piece done. I’m honestly less than enthusiastic about it though. I don’t really like the design or the idea of the entire rear suspension relying on one small contact point. Not sure who at traxxas thought this was a good idea. I made it really snug so it doesn’t wobble, but still I think I might have to figure something else out. At least I can get an idea of how the rear suspension should fit together.
It is an odd choice on Traxxas's part for sure. I'll be interested to see how well it stands up to use.
I think it could be made rock solid relatively easily, and maybe you've already though of this, but some thin plates on the sides that brace the block to the case would probably make it bulletproof provided they don't interfere with anything else.

back in the day, a local company Called C&J Racing Products made a simple H shaped brace to remedy that issue. Kept it from rocking and braced it front to rear as well.

Definitely watching with great interest. I've wanted to do a mid-motor build of my own design for years. With 3-d print and cnc-routers becoming more commonplace, i may have to jump into it. Cant wait to see how yours pans out.
