After reading about and seeing in person at the local HS all the problems Arrma cars are having with
control arm breakage,I decided to see if I could strengthen the known weak spot.
So I decided to wrap the ends of the upper and lower arms with some resin and fiberglass cloth.
I also added a drilled out fender washer (15/64th) to the pivot ball,as someone else pointed out THAT is probably what is the major cause of the plastic arms breaking out of the threads.
Adding a larger diameter flange to the pivot ball would alleviate a lot of stress at the point where the pivot ball threads into the "c" arms.IMO.....hear that Arrma,would be an easy fix for ya!
Here's some pics of what I did and I also made some brass shims from washers to adjust the camber.
And I use a digital angle gauge to get some pretty accurate alignment numbers.
