XV-02 tie rod questions?

[RallyX]

I have an issue with my XV02 where the tie rod end keeps popping off the ball. On the race on Sunday, it happened in the middle of two of the three qualifiers and in the main as well. 

I've replaced the ends a few times with both the standard black ends and the grey low friction ends, and I'm still having the same issue. I was thinking about using the Traxxas style with a screw going through a metal ball in the end. Can't find any Traxxas ends for 3mm, and I seriously doubt they make any short enough anyway. Have any of you done this mod to an XV-02? Which brand did you use? I know Yeah Racing makes some alloy ones, but I'm afraid they'll be too long.

Are you using a servo saver or a solid horn? Maybe a saver would allow some compliance on hard knocks and avoid pop-outs.

I think it's Kyosho that uses a cone washer on top of the ball, so it can't pop off. Maybe that's worth a try?
