yeh, just got done the servo replacing. I had an evader a few years back (brushed) and knew that it has by far, the worst servo mount setup of any RC sold. It is bad enough you have to try and line up the top plate with the bell crank posts, and that the screws are long. but then as you say, you cant re-seat the servo horn if you need to. I got lucky, turning the trim 95% to the right the wheels are straight.
I removed one screw that would not sit flush. just didn't matter what I tried, swapping screws, cleaning out the hole ect, it would not sit flush. The diff doesn't have a ton of play, but I have no way of telling if this was a RTR brushless, or an older that was updated.
gonna take it back out and see if I can get threw a pack.
