Reply to Strange Technic 1210 problem - can anyone help?

Hey,

I'm experiencing a very weird problem when I turn one of my technic 1210 mk2s on and I have absolutely no clue as to what's causing it.

Rather than explain it, I have uploaded a video showing what happens.



Basically, it seems as if there's low torque, the platter judders backwards and forwards and the LEDs flicker. It's as if there's not enough power.

Can anyone offer any advice, or suggest what could be causing the problem?

Thanks,

Adam
