Called DESTROYER 7,7. In bad metal parts. Small resource. I pulled out and replaced the feather feather from solid steel. En see how long.
That would explain why your pins fail and why the real CEN truck parts do not; the weaker metals are substandard and cannot take the torque of the engine.
So, to fix you pin problem, try and see if the real Cenchain GST parts will fit you knock off truck. That should address that one problem. But I hate to say that you most likely will have to fix other parts too since knock-offs in almost all cases, and made horribly as compared to the real RC they are copied from.
