Here is something I'd learn the hard way. Not all Traxxas joints are the same.
I ordered 12 joints to a local hobby shop. Traxxas ref. #2742

They look the right shape and size. But they are not, the rod hole is 2mm, the screw holes M3 and the hexagon shape is 6mm in width (it won't fit in 3DR's rod adapters)
I went ahead and make the holes in the joints and platform wider so I could use M3 screws and fit the carbon rods. Then I realized they only have 45 degreees of freedom. That is too few, at best it can move 8cm side to side, instead of the 17cm expected.
Now I'd ordered the ones Richrap linked KCmodels
Live and learn.
