hey, quite easy to do:
1. The Material
The motor mount is made of small pieces of carbon and glassfiber composites, they also call it "epoxy" "epoxyd"-composites, "GFC". I bought them very cheap at egay. they are actually leftover pieces, but good enough for me.
the green looking gfc-epoxy of the center bar/rear shock mount was an 20x30cm piece, 5mm strong, industrial standard.
2. The glue
There is a 2-component glue/epoxy glue available here, which can be tempered at about 70deg. c. like that you can process the glue for about an hour; to get it finished, I put the pieces into the oven (in the kitchen) for an hour. like that its ready quite quickly, and very, very solid. I really love that stuff (uhu endfest 300). when mixing the 2 substances you also can vary the stiffness or elasticity of the glue.
3. How-to:
The green center stabilizing bar and rear shock mount is made of 5mm quality glass-fiber-composite/epoxy. the original shock tower was made of very weak aluminium, just crap. But I didn't want to buy option parts for expensive $$$, so I made them myself.
I take the original shock tower, lay it on the epoxy; take 2 molegrips to fasten it, drill the first holes and put some screws thru. like that it's easy to work with the saw, drill and file. and it's absolutely exact. the same way the front shock mount was made, material is a sandwich of carbon and epoxy (small leftover pieces). funny: the glassfiber/epoxy shock tower weighs 2 gram less then the original one...
I really recommend that to everyone, who's shock towers are worn out or not stable. better than any option parts. and not expensive.
the center bar is just made by "trial and error". with saw and file. the reason was that there is almost no space for the original aluminium diff-bar (whats its name again), and on the front the space is needed for the esc.
the motor mount is made by a piece of carbon and an aluminium-brace. both pieces put into position, molegrip, glue.
all hand-made with a drill, saw, file, no cnc...
and a bit of madness... huaaa....
