weakness damper rod ends and gears?

[Reo]

Hi, was racing this weekend on a rough clay track for 1:8 buggys. With large jumps, then teh rod end on damper popps off without breaking some thing. this happend to the champ pack dampers and the new big bore. Are the rod ends plastic soft or the hole not tight enough? non of the durangos, B44 or others manged to do that. did break the diff gear to.. make a snapping noise in accelaration. we shimmed it tighter (new gears ) and losend up the slipper a bit.

thx
