try using 1/4" (~6mm) thick plate stock to cut out the shape of the A-arms, then either drill the edge of the plate for Traxxas rod-ends at each end of the A-arm, or make them a bit longer to accept hinge pins like the standard arms use. I'm planning a custom TC/VTA car that I plan to try this on for the front and rear A-arms, as well as the gearbox casing, making use of 1/4" Kydex, with a single 6000 series (or maybe 7000 series, not entirely sure yet) panel to serve as the motor mount. for your application, I'd probably go for some sort of aluminum alloy, to prevent big impacts from fracturing the A-arm where the holes are drilled into the edge, or to keep from pulling the hinge pins/threaded rod out of the abovementioned holes. alternately, stepping up to slightly thicker (say, 7m or 8mm) material and using Kydex or some other type of plastic to keep the weight down and add a bit of give into the suspension
