K1 Fault?

[Moss Models]

I have just built the first of our K1's and I think there is a bit of a weak point there may be a fix for?

At a meeting just before Christmas I saw two team drivers have the same problem with the rear shock ball cups pulling out of the threads. They seemed to have this problem almost every race. I have just built my shocks and noticed the ball cups screw in far too easy and don't really tighten up as the thread is so loose. In other words I think they will pull really easy.

Has everyone else had this problem and if so how did you sort it?

Many thanks.
