The new radio tray places the servo 8mm farther outward than the 1.0, which puts the servo on the flat of the chassis and not in the milled spot. Because of the chamfer on the chassis sides, there is no way for them to machine it any further. Easiest way to check is, with the tray in, remove the radio tray side mud guard and check for clearence. You want about 1mm of clearence so it won't hit when the chassis flexes.
